MariaDB Error 1642: Custom Warning Triggered
Description
Error 1642, "Unhandled user-defined warning condition", indicates that a `SIGNAL` statement within a MariaDB stored program (like a procedure, function, or trigger) has explicitly raised a warning. This warning condition was then returned to the client, but the client application or calling context did not have specific logic implemented to handle this user-defined warning, causing it to be reported as unhandled.
