MySQLERRORNotableStored RoutinesHIGH confidence

Column(s) not allowed here in handler context

Production Risk

Low — compile-time error; the routine will not be created.

What this means

ER_HANDLER_SYNTAX_ERROR (1502, SQLSTATE HY000) is raised when a HANDLER declaration contains columns or syntax that is not valid in that context.

Why it happens
  1. 1Syntax error in a DECLARE HANDLER statement
  2. 2Using column references where they are not allowed in handler declarations
How to reproduce
trigger — this will error
trigger — this will error
CREATE PROCEDURE my_proc()
BEGIN
  DECLARE my_col INT;
  DECLARE CONTINUE HANDLER FOR my_col  -- Column reference not valid here
  SELECT 1;
END;

expected output

ERROR 1502 (HY000): Column(s) not allowed here

Fix

Use valid condition values in DECLARE HANDLER

Use valid condition values in DECLARE HANDLER
CREATE PROCEDURE my_proc()
BEGIN
  DECLARE CONTINUE HANDLER FOR SQLEXCEPTION
  BEGIN
    SELECT 'An error occurred';
  END;
  SELECT * FROM my_table;
END;

Why this works

Handler conditions must be SQLSTATE codes, named conditions, or predefined condition types like SQLEXCEPTION.
