Alters the flow of execution to a label. The Transact-SQL statement or statements that follow GOTO are skipped and processing continues at the label. GOTO statements and labels can be used anywhere within a procedure, batch, or statement block. GOTO statements can be nested.
Define the label: label: Alter the execution: GOTO label
Is the point after which processing starts if a GOTO is targeted to that label. Labels must follow the rules for identifiers. A label can be used as a commenting method whether GOTO is used.
GOTO can exist within conditional control-of-flow statements, statement blocks, or procedures, but it cannot go to a label outside the batch. GOTO branching can go to a label defined before or after GOTO.
GOTO permissions default to any valid user.
The following example shows how to use
GOTO as a branch mechanism.
DECLARE @Counter int; SET @Counter = 1; WHILE @Counter < 10 BEGIN SELECT @Counter SET @Counter = @Counter + 1 IF @Counter = 4 GOTO Branch_One --Jumps to the first branch. IF @Counter = 5 GOTO Branch_Two --This will never execute. END Branch_One: SELECT 'Jumping To Branch One.' GOTO Branch_Three; --This will prevent Branch_Two from executing. Branch_Two: SELECT 'Jumping To Branch Two.' Branch_Three: SELECT 'Jumping To Branch Three.';
