T-SQL (Transact SQL) is a proprietary SQL extension used
by Microsoft SQL Server and Sybase SQL Server. T-SQL adds extensions for
procedural programming. Transaction-SQL is an extended form of SQL that adds
declared variables, transaction control, error and exception handling and row
processing to SQL's existing functions. Microsoft SQL and Sybase both support
T-SQL statements It is largely SQL-92 compliant, so if you're familiar with
another vendor's flavor of SQL, you'll probably feel right at home with
Transact-SQL.
Query Batch
A batch is a group of one or more Transact-SQL statements
sent at the same time from an application to SQL Server for execution.
The most important characteristic of a
batch is that it is parsed and executed on the server as an undivided entity. In
some cases, batches are created implicitly. SQL Server compiles the
statements of a batch into a single executable unit, called an execution plan.
The statements in the execution plan are then executed one at a time.
The given below example shows how to execute query
batch:-
Example:
1> create table workers(
2> ID int,
3> name nvarchar (20),
4> salary int,
5> start_date datetime,
6> city nvarchar (20),
7> region char (5))
8> GO
1>
2> --Inserting Records in a Query Batch
3>
4> SET QUOTED_IDENTIFIER OFF
5> GO
1> INSERT INTO workers (ID, Name) VALUES(01,"Ravi")
2> INSERT INTO workers (ID, Name) VALUES(02,"sapna")
3> INSERT INTO workers (ID, Name) VALUES(03,"Pankaj")
4> INSERT INTO workers (ID, Name) VALUES(04,"Udas")
5> GO
