You specified the FOR UPDATE or FOR READ ONLY clause in a DECLARE CURSOR statement. The FOR UPDATE or FOR READ ONLY clause must be specified in the PREPARE statement, not the DECLARE CURSOR statement. For compatibility with previous versions (but with reduced performance), the sqlpp -m HISTORICAL option can be used to allow the FOR UPDATE or FOR READ ONLY clause in the DECLARE CURSOR statement.

• PREPARE statement [ESQL]
