MySQLERRORCriticalStored RoutinesHIGH confidence
LIMIT clause requires an integer value

Why it happens

How to reproduce
trigger — this will error
trigger — this will error
CREATE PROCEDURE p(lim VARCHAR(10)) BEGIN SELECT * FROM t LIMIT lim; END;
expected output
ERROR 3081 (HY000): LIMIT clause uses a non-integer value.
Fix
Declare the LIMIT variable as an integer type

CREATE PROCEDURE p(lim INT) BEGIN SELECT * FROM t LIMIT lim; END;
Why this works
LIMIT requires an integer; declaring it as INT avoids the type mismatch.
