MySQL Error 1643: Uncaught NOT FOUND Condition
Description
MySQL Error 1643 signifies that a user-defined 'NOT FOUND' condition (SQLSTATE '02000') was signaled within a stored routine (procedure, function, or trigger) but was not caught by an appropriate handler. This typically means the routine's execution terminated unexpectedly because no `DECLARE HANDLER` was defined to manage the signaled condition.
Error Message
Unhandled user-defined not found condition
Known Causes
3 known causesMissing NOT FOUND Handler
A `SIGNAL SQLSTATE '02000'` statement was executed in a stored routine without a corresponding `DECLARE HANDLER` (e.g., `DECLARE EXIT HANDLER FOR SQLSTATE '02000'`) to intercept it.
Incorrect Handler Scope or Type
While a handler might exist, it's defined in a scope where it cannot catch the specific `SIGNAL` statement, or its type (e.g., `CONTINUE` vs. `EXIT`) doesn't achieve the desired error management.
Logic Flaw in Routine
The logic within the stored routine incorrectly triggers `SIGNAL SQLSTATE '02000'` when it shouldn't, or the subsequent error handling path is flawed, allowing the condition to propagate.
