Recursive stored functions and triggers are not allowed
Production Risk
Low — function/trigger fails; no data changed.
What this means
A stored function or trigger attempted to call itself recursively, which is not allowed.
Why it happens
- 1Function calling itself directly
- 2Trigger on table T fires a statement that modifies T, causing the trigger to fire again
How to reproduce
trigger — this will error
trigger — this will error
CREATE FUNCTION f(n INT) RETURNS INT DETERMINISTIC RETURN IF(n<=1, 1, f(n-1)*n);
expected output
ERROR 1424 (HY000): Recursive stored functions and triggers are not allowed
Fix 1
Use an iterative approach with a loop
Why this works
Replace recursion with an explicit loop inside a procedure.
Fix 2
For recursive procedures, increase max_sp_recursion_depth
For recursive procedures, increase max_sp_recursion_depth
SET SESSION max_sp_recursion_depth = 10;
Why this works
Stored procedures (not functions) can be recursive if max_sp_recursion_depth > 0.
