      • getSelectForUpdateString

        public String getSelectForUpdateString()
        INTERNAL: Lock. UPDLOCK seems like the correct table hint to use: HOLDLOCK is too weak - doesn't lock out another read with HOLDLOCK, XLOCK is too strong - locks out another read which doesn't use any locks. UPDLOCK seems to behave exactly like Oracle's FOR UPDATE: locking out updates and other reads with FOR UPDATE but allowing other reads without locks. SQLServer seems to decide itself on the granularity of the lock - it could lock more than the returned rows (for instance a page). It could be forced to obtain to make sure to obtain row level lock: WITH (UPDLOCK, ROWLOCK) However this approach is strongly discouraged because it can consume too much resources: selecting 900 rows from and requiring a "personal" lock for each row may not be feasible because of not enough memory available at the moment - in that case SQLServer will wait until the resource becomes available.

      • shouldPrintLockingClauseAfterWhereClause

FROM ADDRESS WHERE (ADDRESS_ID = ?) FOR UPDATE on SQLServer platform (method returns false): SELECT ADDRESS_ID, ... FROM ADDRESS WITH (UPDLOCK) WHERE (ADDRESS_ID = ?)
