Just add another LOCKING:
LOCKING TABLE a FOR ACCESS
LOCKING TABLE b FOR ACCESS
SELECT
Btw, i would prefer LOCK ROW ACCESS instead:
no need for adding all table names and it automatically upgrades to a table lock when neccessary.
In very old releases there used to be some problems with this approach (in some cases the row lock was upgraded to a table lock with READ
instead of ACCESS), but now only some rare combinations in multi statemnet requests might show that behaviour (if at all).
