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

Foreign key represent a link or say a relationship between columns of tables. Similar to primary key constraint Foreign Key constraint is also of two types. Simple Foreign key constraint and Composite Foreign key constraint. Constraint which involves only one column in foreign key in child table and one column in reference key in parent table is called Simple Foreign Key. While the constraint which involves more than one column in foreign key in child table and more than one column in reference key in the parent table is called Composite Foreign Key.

How to find all database constraints with SQL in Oracle.
 
14:49
I have written a small sql code to find out all database constraints. Just be sure you have dba permission, otherwise you might not view all constraints. To see constraints separately for dba and user you can use user or dba instead of all, like user_constraints or dba_constraints, user_cons_columns, dba_cons_columns. I have used all_ to find out everything instead in a single query.

SQL with Oracle 10g XE - Using ALTER TABLE to Modify Table Columns
 
05:23
In this video I use the ALTER TABLE command to modify an existing field column. The command will allow you to change the data types, whether the field can be null, or even the primary key. When using the ALTER TABLE command you would use the keyword MODIFY to make changes to an existing column. Be careful when changing a data type of the null field as existing data may cause an error if not in compliance with the new change. The code I used to alter the Books table is : ALTER TABLE BOOKS MODIFY ISBN_10 VARCHAR(13); This video is part of a series of videos with the purpose of learning the SQL language.

SQL View
 
11:19
SQL is a standard Structured query language for storing, manipulating and retrieving data in databases. View 1) What is a View? A view is a saved SQL query. A view can also be considered as a virtual table. actually retrieves the data from the underlying base tables. vtblEmployee, vtblDepartment Create View vWName as sql query Views can be used to reduce the complexity of the database schema, for non IT users. Views can be used as a mechanism to implement row and column level security. Row Level Security where tblDepartment.DeptName = 'IT' To look at view definition - sp_helptext vWName ; To modify a view - ALTER VIEW statement ; To Drop a view - DROP VIEW vWName. 2) Updateable Views Is it possible to Insert, Update and delete rows, from the underlying tblEmployees table, using view vWEmployeesDataExceptSalary? Yes, SQL server views are updateable. Update vWEmployeesDataExceptSalary Set Name = 'Mikey' Where Id = 2 3) Indexed views when you create an index, on a view, the view gets materialized. This means, the view is now, capable of storing data. In SQL server, we call them Indexed views and in Oracle, Materialized views. vtblProduct , vtblProductSales If you want to create an Index, on a view, the following rules should be followed by the view. For the complete list of all rules, please check MSDN. 1. The view should be created with SchemaBinding option 2. If an Aggregate function in the SELECT LIST, references an expression, and if there is a possibility for that expression to become NULL, then, a replacement value should be specified. In this example, we are using, ISNULL() function, to replace NULL values with ZERO. 3. If GROUP BY is specified, the view select list must contain a COUNT_BIG(*) expression 4. The base tables in the view, should be referenced with 2 part name. In this example, tblProduct and tblProductSales are referenced using dbo.tblProduct and dbo.tblProductSales respectively. Limitation : 1. You cannot pass parameters to a view. Table Valued functions are an excellent replacement for parameterized views. 2.Rules and Defaults cannot be associated with views. 3.The ORDER BY clause is invalid in views unless TOP or FOR XML is also specified. 4.Views cannot be based on temporary tables.

SQL Tutorial 4:  Use ALTER , UPDATE, DELETE, and DROP statements

How do you ALTER, UPDATE, DELETE, DROP table in a database? A standard SQL scripts are applicable to all database vendors such as Informix, SQL Server, Oracle, MySQL when employing this command including DB2. The video explains how to ALTER table. Alter command is used when you add or DROP column/s in a table. Make sure you execute REORG TABLE after the alteration. When changes are required to a row data, execute the UPDATE SET command. WHERE clause must be included to isolate records that fall on the criterion. Failure to do so will update the entire column of that table if done carelessly. WHERE clause is also used when executing a DELETE sql script. If you fail to include WHERE clause, the entire rows in the table will be deleted. Execute with caution when working with DROP command. On most cases, the changes are irreversible when you are done executing this command. You may DROP column, table, views, stored procedure, user defined functions, database or simply combined it with ALTER command.
