Error during compilation of event body

Production Risk

Low — DDL error; the event will not be created.

What this means

ER_EVENT_COMPILE_ERROR (1557, SQLSTATE HY000) is raised when the SQL body of an event contains a syntax or semantic error that prevents it from being compiled.

Why it happens
  1. 1Syntax error in the SQL statement in the event DO clause
  2. 2References to nonexistent tables or columns in the event body
How to reproduce
trigger — this will error
trigger — this will error
CREATE EVENT bad_event
ON SCHEDULE EVERY 1 HOUR
DO SELCT 1;  -- Typo: SELCT instead of SELECT

expected output

ERROR 1557 (HY000): Error during compilation of event's body

Fix

Fix the SQL syntax in the event body

Fix the SQL syntax in the event body
CREATE EVENT good_event
ON SCHEDULE EVERY 1 HOUR
DO SELECT 1;

Why this works

The event body must contain valid SQL; test the SQL independently before embedding it in an event.
