Property of a FILE that controls what isolation level is used within a transaction frame. This property is valid on all SQL based drivers (except Oracle). The default value is 8.

PROP:LogoutIsolationLevel uses the ODBC isolation level standard. This may not be the same as the isolation levels documented on the target driver's native back end. For example, with Sybase's ASA, the documented isolation levels are 0, 1, 2 and 3 and they correspond to

| **ODBC level** | **Sybase Level** |
| 1 | 0 |
| 2 | 1 |
| 4 | 2 |
| 8 | 3 |
| 16 | N/A |
