GO

Send the current batch of T-SQL statements to an instance of SQL Server.

Syntax
      GO [--comment]

Key
   comment    Optional comment text.

The scope of local (user-defined) variables is limited to a batch, and cannot be referenced after a GO command.
Execution of a stored procedure after the first statement in a batch must include the EXECUTE keyword.

Example

DECLARE @MyString VARCHAR(20)
SELECT @MyString = 'Hello World'
PRINT @MyString
GO
-- Next line will error because the variable was declared before this batch.
PRINT @MyString
GO
