When the isolation level is Read Committed and a SELECT FOR UPDATE statement is issued against some data stores, the OpenAccess SDK Client does not lock the expected row.
Valid values
0 | 1
- 0=The appropriate row will be locked. Specifying 0 degrades the performance for SELECT FOR UPDATE statements because rows are fetched one at a time.
- 1=The appropriate row is not locked.
Default
1
Type
Dynamic
For more information about isolation levels, refer to the OpenAccess SDK Client Reference.
