T-SQL

TRANSACT STRUCTURED QUERY LANGUAGE

            This is a 4^th generated intermediate language between user and SQL Server. Whenever user wants to interact with SQL Server, he has to interact with SQL Server through T-SQL. It includes the following Sub Languages

1. DDL (Data Definition Language)
2. DML (Data Manipulation Language)
3. DCL (Data Control Language)
4. TCL (Transaction Control Language)

Things to Observe:

1. While writing the Queries using T-SQL in SQL Server Management Studio we need not to follow any particular case. Because T-SQL is case insensitive language.
2. After writing the Query, we need to select that query using either mouse or keyboard.
3. Now Press F5 ( Execute Key).
4. Then the results are displayed in a separate window called Result window or Result Pane.
5. Use Ctrl+R to Hide/Show the Result window or Result Pane.
6. Use F8 for Object Explorer

Note:

1. SQL SERVER can handle nearly 32767 Databases
2. Each Database can handle nearly 2 billion Database Objects.
3. Each Table can handle nearly 1024 columns
4. Each Table can handle nearly 1 million Rows.
