MySQLERRORNotableStored RoutinesHIGH confidence

Routine body is too long

Production Risk

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

What this means

ER_TOO_LONG_BODY (1461, SQLSTATE HY000) is raised when the body of a stored procedure, function, trigger, or event exceeds the maximum allowed size.

Why it happens
  1. 1Stored routine body exceeds the internal size limit
  2. 2Very long SQL statements or large numbers of statements in a single routine
How to reproduce
trigger — this will error
trigger — this will error
-- A stored procedure with an extremely long body
CREATE PROCEDURE huge_proc()
BEGIN
  -- Thousands of lines of SQL...
END;

expected output

ERROR 1461 (HY000): Can't create more than max_prepared_stmt_count statements (current value: 16382)

Fix

Split the routine into smaller sub-routines

Split the routine into smaller sub-routines
-- Break into multiple procedures called from a parent:
CREATE PROCEDURE part1() BEGIN ... END;
CREATE PROCEDURE part2() BEGIN ... END;
CREATE PROCEDURE main_proc()
BEGIN
  CALL part1();
  CALL part2();
END;

Why this works

Splitting large routines into smaller ones reduces each individual body size below the limit.
