Module error 

Enums

DbError

ErrorClass

StmtOutcome

Represents the outcome of executing a SQL statement. Control flow signals (BREAK, CONTINUE, RETURN) are modeled on the success path rather than as error variants, preventing accidental swallowing by catch-all error handlers and keeping TRY…CATCH semantics clean.

Type Aliases

StmtResult

Convenience type alias for statement execution results.
