Error handling in a cursor

    I am building a script which has a cursor in it.  It is pretty simple, but I am wondering how to use error handling within the cursor.  The code below is basically what I am doing:

    WHILE @@FETCH_STATUS = 0

     BEGIN

     DECLARE @l_error int

      DECLARE @l_filename VARCHAR(255)

       EXECUTE @l_error = sp_xxxxxxxxx @l_filename

     IF (@l_error = 0)

        PRINT 'Applied Script ' + @l_file_name

     ELSE

        PRINT 'FAILED'

      

     FETCH NEXT FROM files INTO @l_file_name

     END

    What I need to have is if an error does happen the cursor stops and gets out of the cursor.

    Use BREAK to get out of the current WHILE loop.

    Yes, PW is right. BREAK will exit the WHILE loop.

    That works perfectly for jumping out of the loop.  I tried putting a print statement with the break to state the table name that the error occured on but it reads as a syntax error.  Any ideas how I might accomplish that?

    Print doesn't handle in-line string concatenation. Build your error msg including the table name into a varchar variable and Print the variable.
