MariaDB Error 1646: SQLSTATE Required for SIGNAL CONDITION
Description
This error indicates that a `SIGNAL` or `RESIGNAL` statement attempted to use a `CONDITION` that was not explicitly defined with a `SQLSTATE` clause. In MariaDB, conditions used for signaling custom errors or warnings must be associated with a specific five-character `SQLSTATE` value for proper error handling and propagation.
Error Message
SIGNAL/RESIGNAL can only use a CONDITION defined with SQLSTATE
Known Causes
3 known causesCONDITION Missing SQLSTATE
A `DECLARE CONDITION` statement was used without specifying the `SQLSTATE 'NNNNN'` clause, which is mandatory for conditions intended for `SIGNAL` or `RESIGNAL` statements.
Incorrect Condition Declaration
The `CONDITION` was declared without an explicit `SQLSTATE`, possibly due to a misunderstanding of how `SIGNAL`/`RESIGNAL` interact with condition handling in MariaDB.
Syntactic Mismatch
The code might have been adapted from a different SQL dialect or an older version of MariaDB/MySQL where `CONDITION` definitions for `SIGNAL`/`RESIGNAL` had different or less strict requirements.
