We can also say that SQL tables are kind of data structure which are used by database for efficient storage of data. To create a table in our database we use SQL CREATE TABLE command. SQL CREATE TABLE is a type of DATA DEFINITION LANGUAGE also known as DDL. To Create a table in your schema you will require CREATE TABLE system privilege. In our future videos we will see what are system and object privileges and how to grant them to a user. Today for this video we will be using Sample schema HR which already has all the necessary privileges. Ohk Let's see the syntax. CREATE TABLE table name ( column name1 Data-Type(size), column name2 Data-Type(size), ..... ); CREATE TABLE is an oracle reserved word or say an Oracle key word whereas There are 3 different ways of creating a table in Oracle database. Creating a table using Command Line Interface (CLI) in Oracle database For demonstrating how to create table in oracle database using CLI, I'll be using Command prompt. Thats how we create table using command prompt. you can check your table structure by DESCRIBE command for that just write DESC and your table name. Like this Another way of creating a table is by using Graphic user interface (GUI) in Oracle database To demonstrate how to create table using GUI we will use SQL developer. Lets open our SQL developer I am connected to HR schema if you do not know how to create a connection to database using SQL developer please watch my oracle database tutorial 4 that explains database connectivity using SQL developer and command prompt. Link for this video is in the description below. So lets create a table. Creating a table using SQL developer is very easy we do not have to fire any query here. Let's start First of all right click on your connection in which you want to create a table and choose schema browser. This will open a separate schema browser pane or you can expend your connection by clicking this + sign and then right click on table and choose New Table. However I prefer working with schema browser so let's skip to schema browser pane here from the first drop-down list you can choose connection name and in the second drop down list you can choose what database objects you want to work with we want to create a table thus I'll choose table and then click this arrow here and choose option for new table Ok we have created a table wizard first of all give a unique name to your table and add some column as well. For this, click the green plus button. Now we already have a column so give it some name. Also choose a datatype from the list and specify any size you can check this not null column if in case you want to make this a mandatory column you can also specify default value and constraint If you want to make this column a primary key you can click here In my future video i'll show you what are these constraints and different ways of applying them on a column in a table. for this video we will concentrate on create table only so when you are done with all your columns click ok Thats your table You can double click on your table here and can see its structure. Thats it

Oracle Database 12c Security - Oracle Virtual Private Database (VPD)
 
12:29
Learn how to use Oracle Virtual Private Database (VPD) to secure your data. See all lessons at http://skillbuilders.com/12c-TSDP-Tutorial First, Virtual Private Database. What is it? Answer: It's a declarative technique for enforcing security. Typically, it's based on user application context. That was the first limitation of 8i. Backed with 8i context were session-specific. The context variables were sort in the PGA. That means you simply couldn't use this in a web environment. However, global context, with use of 9i, Virtual Private Database became usable for web applications with connection pooling. But whether you're using it to client server or on a three tier environment, it's declarative technique rather than a programmatic technique. I can go behind the back of the application as a DBA and generate predicates to get appended to all SQLs. Select, insert, update, delete the end users. Issue the SQL and I will generate a predicate that filters the access. It's impossible to bypass. All users will have predicates appended to all their code. It doesn't matter whether they're using SQL Plus, Discoverer, Business Objects, Crystal Reports, eBusiness Suites, whatever they're using, I as DBA can filter their access to roles. The end result, different users see different data sets while running the same code and accessing the same tables, hence, the name Virtual Private Database. Different users will think they're seeing a totally different set of tables, but in fact it's one column database, one set of tables hosting a single application shared by all the users. The mechanism - you can apply VPD to tables, to views, to synonyms, and a declarative technique. Once the technique you write a function that generates the predicate, you associate the function with the table. From then on whenever the user issue SQL against that table the Cost-Based Optimizer rewrites the code. The Cost-Based Optimizer rewrites the user SQL to call the function to generate the predicate. The predicate is then appended to the SQL and it's the modified SQL that is parsed and executed. Let's see how this actually works. I'm working here by the way. This is just a perfectly normal 12.1 database. But what I'm going to demonstrate at this point will in fact work on 11g as well. I'm not going to be using any of the 12c enhancements to VPD for this little demonstration. I'll work in the scott schema. What do we have to do? We write a function to generate the predicate string. Create function. And I'll my function vpdf. The function must conform to a fixed specification. It must take two varchar arguments. One of the arguments is intended to be the schema to which the function will be applied. The other argument is the object within the schema to which the function will be applied. And it must return a varchar2, which is the generated predicate. Let's begin. Within this function you can do just about anything. There are some limitations. It's impossible for the function to query or update the table against which the VPD calls here is going to be applied or we violate the rules of purity that we come across so often with PL/SQL. But apart from that, it can do just about anything - including a number of dreadful side effects can be introduced by writing VPD functions. I'm going to do a very simple one on this one. I'll shall simple return immediately a predicate. What predicate? Ename, which is the ename column from this scott.emp table. Ename should equal sys_context. I'll go to the local context, my user end context, and just extract session user. We can see that John has tested this earlier today and therefore the object already was suggesting and he's just dropping it now and cleaning up the recreate. I hope you realize these really are live demonstrations. I'm not just running scripts. I've created a function. What's that function going to do? It's going to return this value here. Test it. Always test it and see what it's actually going to do. I'll select vpdf. I have to give it a couple of arguments. This one will do for now.

Oracle SQL Tutorial 21 - How to Create / Drop Indexes
 
03:58
In the last video, we wrote up the SQL to create three tables: CREATE TABLE users( user_id NUMBER, username VARCHAR2(50 CHAR) UNIQUE, CONSTRAINT users_pk PRIMARY KEY (user_id) ); CREATE TABLE projects( project_id NUMBER, Project_name VARCHAR2(50 CHAR) UNIQUE, creator VARCHAR2(50 CHAR) NOT NULL, CONSTRAINT projects_pk PRIMARY KEY (project_id), CONSTRAINT projects_users_fk FOREIGN KEY (creator) REFERENCES users (username) ON DELETE CASCADE ); CREATE TABLE project_users( project_id NUMBER NOT NULL REFERENCES projects (project_id) ON DELETE CASCADE, user_id NUMBER NOT NULL REFERENCES users (user_id) ON DELETE CASCADE, CONSTRAINT project_users_pk PRIMARY KEY (project_id, user_id) ); I'm going to increase the size of the users table a bit by adding a first and last name column. CREATE TABLE users( user_id NUMBER, username VARCHAR2(50 CHAR) UNIQUE, first_name VARCHAR2(50 CHAR), last_name VARCHAR2 (50 CHAR), CONSTRAINT users_pk PRIMARY KEY (user_id) ); But before we finish this design, we should consider indexing certain columns. What columns should we index? Well, as a reminder, the columns that are indexed by default are columns with the UNIQUE constraint, and those that are labeled as primary keys. Columns that are not indexed but often should be are those labeled as a foreign key. The column that jumps out the most to me is the creator column of the project table. It's the only foreign key that is not part of some index. Let's fix this by creating our first index. The way we do that is with the CREATE INDEX command. CREATE INDEX projects_creator_ix ON projects (creator) What naming convention are we following for the index? We are naming it by the table name, followed by an underscore, followed by the column, followed by an underscore, followed by an ix (for index). In this situation it does not apply, but if our foreign key column is labeled as UNIQUE, we can add the UNIQUE keyword like this: CREATE UNIQUE INDEX projects_creator_ix ON projects (creator) Now if you want to get rid of an INDEX, you can use this command: DROP INDEX projects_creator_ix Now, if we want to select data from the user table and the project table we can do that much faster. That's because the foreign key and column it references are both indexed and those are the columns we would do the join on. We will discuss how to do joins in a future video. So what are some potential problems with this database design? Overall, it is pretty good. With this design though we need to make sure there is no way for someone to update a user's username. In the next video we are going to discuss why. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me on Patreon! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

This means a given student can be enrolled into many courses and a given course can have many students enrolled. Below is the question asked in an interview for SQL Server Developer role. Write a SQL script to insert data into StudentCourses table. Here are the rules that your script should follow. 1. There will be 2 inputs for the script Student Name - The name of the student who wants to enroll into a course Course Name - The name of the course the student wants to enroll into 2. If the student is already in the Students table, then use that existing Student Id. If the student is not already in the Students table, then a row for that student must be inserted into the Students table, and use that new student id. 3. Along the same lines, if the course is already in the Courses table, then use that existing Course Id. If the course is not already in the Courses table, then a row for that course must be inserted into the Courses table, and use that new course id. 4. There should be no duplicate student course enrollments, i.e a given student must not be enrolled in the same course twice. For example, Tom must not be enrolled in C# course twice. Answer : To avoid duplicate student course enrollments create a composite primary key on StudentId and CourseId columns in StudentCourses table. With this composite primary key in place, if someone tries to enroll the same student in the same course again we get violation of primary key constraint error. Alter table StudentCourses Add Constraint PK_StudentCourses Primary Key Clustered (CourseId, StudentId) Here is the SQL script that inserts data into the 3 tables as expected Declare @StudentName nvarchar(50) = 'Sam' Declare @CourseName nvarchar(50) = 'SQL Server' Declare @StudentId int Declare @CourseId int -- If the student already exists, use the existing student ID Select @StudentId = Id from Students where StudentName = @StudentName -- If the course already exists, use the existing course ID Select @CourseId = Id from Courses where CourseName = @CourseName -- If the student does not exist in the Students table If (@StudentId is null) Begin -- Insert the student Insert into Students values(@StudentName) -- Get the Id of the student Select @StudentId = SCOPE_IDENTITY() End -- If the course does not exist in the Courses table If (@CourseId is null) Begin -- Insert the course Insert into Courses values(@CourseName) -- Get the Id of the course Select @CourseId = SCOPE_IDENTITY() End -- Insert StudentId & CourseId in StudentCourses table Insert into StudentCourses values(@StudentId, @CourseId) If required, we can very easily convert this into a stored procedure as shown below. Create procedure spInsertIntoStudentCourses @StudentName nvarchar(50), @CourseName nvarchar(50) as Begin Declare @StudentId int Declare @CourseId int Select @StudentId = Id from Students where StudentName = @StudentName Select @CourseId = Id from Courses where CourseName = @CourseName If (@StudentId is null) Begin Insert into Students values(@StudentName) Select @StudentId = SCOPE_IDENTITY() End If (@CourseId is null) Begin Insert into Courses values(@CourseName) Select @CourseId = SCOPE_IDENTITY() End Insert into StudentCourses values(@StudentId, @CourseId) End Use the following statement to execute the stored procedure Execute spInsertIntoStudentCourses 'Tom','C#'

Oracle SQL Tutorial 11 - CREATE TABLE
 
05:04
The way you create a table is to use the CREATE TABLE command. CREATE TABLE users() So in this situation, the name comes right after the TABLE keyword. The next thing we do is put all of the columns on a line that we want to put in our table. CREATE TABLE users( user_id, username, first_name, last_name ) Notice the naming conventions here. For this series we are going to make columns with what is known as snake casing. This is where each individual word is separated by an underscore. if you have more than one column, all of them have to have commas except the last one. The comma is a way to say that another column is coming, so you don't need to do it on the last one. Now you would think we were done, but we also have to say what data type each column is. Later we will extensively discuss data types so we can focus on them exclusively. For now, here are the data types we are going to use: CREATE TABLE users( user_id NUMBER, username VARCHAR2(50), first_name VARCHAR2(50), last_name VARCHAR2(50) ) Now, inside of the parenthesis for varchar2, we pass in a number... This is the max length of the string. But the question is, what is it measured in? The default is actually in bytes, not characters. For example if we have the string hello, it is 5 characters, but it might take up a total of 10 bytes of storage. So I would recommend adding the keyword char right after the number so it defaults to 50 characters, not bytes. CREATE TABLE users( user_id NUMBER, username VARCHAR(50 CHAR), first_name VARCHAR2(50 CHAR), last_name VARCHAR2(50 CHAR) ) This will work to create a table, but it's really missing a lot of information… which column is the primary key? Are we adding any indexes? Is there any thing else we need to say about these columns? So as you can tell, we are making progress, but there is still so much to learn. The biggest gotcha to remember from this video is that the data type VARCHAR ends in a 2, stupid, right? who would end the name of something with a 2?

One of SQL Developer’s most popular features has undergone a significant upgrade. Users can quickly define and recall delimited or Excel files to be imported to a new or existing Oracle table. Data preview and validation is provided for each column, as well as ‘best guess’ data type and date format mask mapping. This process can now be automated via the SQL Developer command line interface (SDCLI) ‘Import’ command. NOTE: This is a video only. There is no audio. Copyright © 2015 Oracle and/or its affiliates.

SQL Tutorial 2: Overview of SQL
 
40:34
http://www.gcreddy.com/2016/08/sql-overview.html Overview of SQL, Structured Query Language Syntax, SQL Data Types, SQL Operators, SQL Built in Functions, SQL Queries and Sub Queries. Data Definition Language, Data Manipulation Language and Data Control Language Commands. Overview of Structured Query Language • SQL (Structured Query Language) is a standard language for accessing databases. • All Relational Database Management Systems like MS Access, MS SQL Server, Oracle, Sybase, MySQL, DB2 use SQL as standard database language. i. Environment Setup We can practice SQL Commands in any Database Management System, Install any Database Engine and practice. ii. SQL Syntax • A database contains one or more tables. Each table is identified by a name, Tables contain records (rows. with data. • Most of the actions we need to perform on a database are done with SQL statements. • SQL keywords are Not case sensitive: select is the same as SELECT • All the SQL statements start with any of the keywords like SELECT, INSERT, UPDATE, DELETE etc... and all the statements end with a semicolon (;., it is the standard way to separate SQL Statements. iii. SQL Data Types • A data type defines what kind of value a column can contain, we have to use data types while creating database tables, choose a particular data type for a table column based on our requirement. Example: Character Data Types Numeric Data Types Date and Time Data Types Etc... • Data Types vary from One Database Management System to another iv. Operators Operators are used to perform Arithmetic, Comparison and Logical Operations. Categories of Operators in SQL 1. Arithmetic Operators 2. Comparison Operators 3. Logical Operators v SQL Functions SQL has many built-in functions for performing processing on data. Categories of Built-in Functions in SQL 1. Aggregate Functions 2. String Functions 3. Date Functions Etc... vi. Data Definition Language The Data Definition Language (DDL) is used to create and destroy databases and database objects. Important Operations • Create Database • Use Database (Specify the Database you wish to work with within your DBMS) • Alter Database • Drop Table, Drop Database vii. Data Manipulation Language The Data Manipulation Language (DML. is used to insert, retrieve and modify database information) Important Operations • Insert Records to an existing Table • Retrieve the specific information from an operational database. • Modify information contained within a Table. • Delete information contained within a Table. viii. Data Control Language The Data Control Language (DCL) allows database administrators to configure security access to relational databases. Important Operations • Provide access on the Database objects to the Users • Remove User access rights to the Database Objects • Deny Permissions to Users. ix. SQL SELECT Statement The SELECT statement is used to select data from a database. • General Selection • Conditional Selection Etc... (We use clauses, Operators and keywords...) x. SQL Joins The SQL Joins clause is used to combine records from two or more tables in a database. Different SQL Joins: 1. Inner Join 2. Left Join 3. Right Join 4. Full Join ----------------------------------------------------

Set Up a new Connection in Oracle SQL Developer
 
02:23
https://www.databasestar.com/introduction-oracle-sql-course/ In this video, I’ll show you how to set up a connection in SQL Developer. SQL Developer is Oracle’s free IDE for working with your SQL database. It’s one of the best tools available, and used by a lot of people. As part of my Introduction to Oracle SQL series of videos, I use SQL Developer to set up the data and explain the concepts. The first step once you have downloaded the application is to set up a connection. What is a connection? A connection in SQL Developer lets you connect to a database. You enter in a set of data once for your database, and SQL Developer remembers this and lets you connect to the database. You provide the following data: - Connection name - Username - Password - Server details (e.g. server, port, SID) The connection can have a name to help you remember it in the future. Connections can also be colour coded to make it easier to see which connection you’re working on! So, to find out how to set up a connection in SQL Developer, watch this video! Let me know in the comments if you have any questions.

in this video i will show you how to use select statement and sql plus commands and many more, join our group for more detail https://www.facebook.com/groups/242999206136244/, The Four main categories of SQL statements are as follows: 1. DML (Data Manipulation Language) 2. DDL (Data Definition Language) 3. DCL (Data Control Language) 4. TCL (Transaction Control Language) -------------------------------------------------------------------------- DML statements include the following: SELECT – select records from a table INSERT – insert new records UPDATE – update/Modify existing records DELETE – delete existing records -------------------------------------------------------------------------- DDL statements are used to alter/modify a database or table structure and schema. These statements handle the design and storage of database objects. CREATE – create a new Table, database, schema ALTER – alter existing table, column description DROP – delete existing objects from database -------------------------------------------------------------------------- DCL statements control the level of access that users have on database objects. GRANT – allows users to read/write on certain database objects REVOKE – keeps users from read/write permission on database objects. -------------------------------------------------------------------------- TCL statements allow you to control and manage transactions to maintain the integrity of data within SQL statements. BEGIN Transaction – opens a transaction COMMIT Transaction – commits a transaction ROLLBACK Transaction – ROLLBACK a transaction in case of any error. ------------- .---------------------------------------------------------------------------------------------------------. video courses- list of playlist : tips and trics link► https://www.youtube.com/playlist?list=PLOfLYVXrwqXrI5jvwUEi6N13QR4xCj2k2 command prompt commands: link►https://www.youtube.com/playlist?list=PLOfLYVXrwqXobXGUdGk6JhzyQ216dNiQL oracle sql: link►https://www.youtube.com/playlist?list=PLOfLYVXrwqXqoUWCoh4cARGDW13SofDO- c programming: link►https://www.youtube.com/playlist?list=PLOfLYVXrwqXrZ_Ub8EXeLY7YP1YxhoJzf .-----------------------------------------------------------------------------------------------------------. watch more videos: learn oracle sql online overview tutorail : https://www.youtube.com/watch?v=Dfesgj4w8QA&t=8s how to fix or repair a corrupted usb flash drive or cd card using command prompt: https://www.youtube.com/edit?video_id... how to copy a folder using cmd: https://www.youtube.com/watch?v=Lblhb... how to move a folder using cmd: https://www.youtube.com/watch?v=YFfHZ... how to dell files in cmd: https://www.youtube.com/watch?v=3-lqg... how to make and remove directory: https://www.youtube.com/edit?video_id... how to change color and title in cmd: https://www.youtube.com/edit?video_id... how to change directory in command prompt: https://www.youtube.com/watch?v=SmLYx... .-----------------------------------------------------------------------------------------------------------. social media links: join our group: ► https://www.facebook.com/groups/24299... ► Follow on Google+: http://[email protected] ► Follow on Twitter: https://twitter.com/@rananavi4766669 :

GridView insert update delete in asp.net - Part 23
 
23:47
Link for csharp, asp.net, ado.net, dotnet basics and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for text version of this video http://csharp-video-tutorials.blogspot.com/2013/03/gridview-insert-update-delete-in-aspnet.html In this video we will discuss about performing an insert, update and delete on asp.net gridview control using sqldatasource. We will be using tblEmployee table for this demo. SQL script to create and populate this table with sample data is available in Part 13 of asp.net gridview tutorial. Create an asp.net web application. Drag and drop a gridview and a sqldatasource control on WebForm1.aspx. Configure "SqlDataSource1" control 1. Right click on "SqlDataSource1" control and select "Show Smart Tag" 2. Now click on "Configure Data Source" link 3. Select connection string, from the dropdownlist on "Choose your data connection" screen. You need to have a connection string specified in web.config file. 4. Click Next 5. On "Configure the Select Statement" screen, select "tblEmployee" table from dropdownlist. 6. Click on "Advanced" button 7. Select "Generate INSERT, UPDATE and DELETE statements" checkbox and click OK 8. Click Next and Finish Drag and drop gridview control on WebForm1.aspx. Now let us associate "SqlDataSource1" control with "GridView1" control 1. Right click on "GridView1" control and select "Show Smart Tag" 2. Select "SqlDataSource1" from "Choose Data Source" dropdownlist 3. Select "Enable Deleting" and "Enable Editing" checkboxes. At this point "Delete" and "Edit" buttons should appear on the gridview control. We will be using gridview control's footer for inserting a new record. Set "ShowFooter" property of the GridView1 control to "true". This can be done from the properties window, or in the HTML. By default GridView control has generated bound fields to display EmployeeId, Name, Gender and City columns. We need to convert these bound fields into template fields. This can be done very easily using the designer. 1. On the "GridView Tasks" pane click on "Edit Columns" link button. 2. Select "EmployeeId" from "Selected Fields" section and click on "Convert this field into a template field" link 3. Do the same for Name, Gender and City Now modify the template fields in the HTML. Please note 1. In every TemplateField, along with EditItemTemplate and ItemTemplate, we also need FooterTemplate. 2. A dropdownlist is used in EditItemTemplate and FooterTemplate of "Gender" template field, instead of a textbox control. 3. To validate data during edit and insert operations, notice that, we are using validation controls, in EditItemTemplate and FooterTemplate. 4. A linkbutton is used in the footer template of "EmployeeId" template field, to enable the user to insert a new employee row 5. We have used ValidationGroup="Insert" for all the validation controls in FooterTemplates. LinkButton's ValidationGroup is aslo set to "Insert", so that all the validation controls in in FooterTemplates are fired only on Insert LinkButton click. 6. We have set LinkButton's OnClick="lbInsert_Click". 7. After the closing tag of GridView, notice that we are using 2 validationsummary controls, to display all the validation messages in one place. ValidationSummary1 control's ValidationGroup is set to "Insert". ValidationSummary1 control displays all insert related validation errors, and edit related validation errors are displayed using ValidationSummary2 control. Finally copy and paste the following event handler method in WebForm1.aspx.cs protected void lbInsert_Click(object sender, EventArgs e) { SqlDataSource1.InsertParameters["Name"].DefaultValue = ((TextBox)GridView1.FooterRow.FindControl("txtName")).Text; SqlDataSource1.InsertParameters["Gender"].DefaultValue = ((DropDownList)GridView1.FooterRow.FindControl("ddlGender")).SelectedValue; SqlDataSource1.InsertParameters["City"].DefaultValue = ((TextBox)GridView1.FooterRow.FindControl("txtCity")).Text; SqlDataSource1.Insert(); }
