BEGIN...END (TSQL Statement)

Encloses a series of TSQL statements as a block, so that they are syntaxically treated as a single statement.

This construct is often used in combination with IF...ELSE and WHILE statements.

Syntax

BEGIN
    <statement_1>
    ...
    <statement_n>
END

Arguments

<statement_1>…<statement_n>

series of any valid TSQL statements.

Remarks

BEGIN...END blocks can be nested.

Examples

CREATE TABLE t (a INT NOT NULL PRIMARY KEY, VARCHAR(50));
GO

DECLARE @i INT = 100;

BEGIN TRANSACTION;

WHILE @i < 105
  BEGIN
  INSERT INTO t VALUES(@i, 'hello_' + CAST(@i AS VARCHAR));
  SET @i += 1;
  END

COMMIT TRANSACTION;

SELECT * FROM t;
GO

The result is:

a          |b              |

        100|hello_100      |

        102|hello_102      |
        103|hello_103      |
