The LockType property sets or returns a LockTypeEnum value that specifies the type of locking when editing a record in a Recordset. Default is adLockReadOnly. This property is read/write on a closed Recordset and read-only on an open Recordset.
Note: Set this property before opening the Recordset.
Note: Not all providers support all lock types. If the requested LockType setting is not supported, the provider will choose another type of locking. You can use the Supports method to determine the actual locking functionality available in a Recordset object.
Note: adLockPessimistic is not supported if CursorLocation is set to adUseClient.
