GOTO Statement in SQL Server

After a condition/statement execution, if we need to alter the flow of execution to start from a particular label, then GOTO statement will help you. Basically, GOTO keyword uses to skip statement process and continue from a particular label.
GOTO Statement in SQL Server contains two parts –

     GOTO statement declaration: GOTO statement contains GOTO keywords and label_name as below.


GOTO label_name


    Label Declaration: Label contains label_name only with at least one statement as below.


label_name:
select * from tbl


Label_name must be unique within the scope of the code and after label_name declaration, there should be one SQL-statement.

Example: How can we use GOTO statement in SQL server, you can see below.


DECLARE @rating INT=10
WHILE @rating>0
BEGIN
            IF @rating=8
                        GOTO Codefari
            SET @rating=@rating-1
            PRINT @rating
END

Codefari:
PRINT 'www.codefari.com'



In above example, we have created one GOTO statement lable_name is Codefari if the @rating value is 8 then code will branch to the label called Codefari.
