The LockType class contains the fields shown in the following table.
Constant | Value | Description |
UNSPECIFIED | -1 | Does not specify a type of lock. For clones, the clone is created with the same lock type as the original. |
READONLY | 1 | Indicates read-only. You cannot alter the data. |
PESSIMISTIC | 2 | Indicates pessimistic locking, record by record—the provider does what is necessary to ensure successful editing of the records, usually by locking records at the data source immediately upon editing. |
OPTIMISTIC | 3 | Indicates optimistic locking, record by record. The provider uses optimistic locking, locking records only when you call the Recordset.update method. |
BATCHOPTIMISTIC | 4 | Indicates optimistic batch updates. Required for batch update mode as opposed to immediate update mode. |
