EDBI Routines for MySQL (InnoDB engine) Data mapping (any COMP type could be used, mapping is done according to the digits): PIC X(n) VARCHAR(n) PIC 9(1-2) TINYINT PIC 9(3-4) SMALLINT PIC 9(5-6) MEDIUMINT PIC 9(7-9) INT PIC 9(>9) BIGINT PIC 9(n)V9(m) DECIMAL(n+m,m) PIC S9(n)V9(m) DECIMAL(n+m,m) Peculiar jdbc settings: iscobol.jdbc.autocommit=false This is set in order to take a lock if issued. The COBOL program shouldn’t use COMMIT and ROLLBACK statements in order to avoid conflicts with the operations performed by EDBI routines. iscobol.jdbc.on_stop_run=commit Due to the above setting, it’s good practice to instruct the runtime to commit all modifications before exiting.
