Members
| Member name | Description | |
|---|---|---|
| Null | This callback is reserved and always considered invalid. | |
| Finalize | A finalizable column has gone to zero. | |
| BeforeInsert | This callback will occur just before a new record is inserted into a table by a call to JetUpdate. | |
| AfterInsert | This callback will occur just after a new record has been inserted into a table by a call to JetUpdate but before JetUpdate returns. | |
| BeforeReplace | This callback will occur just prior to an existing record in a table being changed by a call to JetUpdate. | |
| AfterReplace | This callback will occur just after an existing record in a table has been changed by a call to JetUpdate but prior to JetUpdate returning. | |
| BeforeDelete | This callback will occur just before an existing record in a table is deleted by a call to JetDelete. | |
| AfterDelete | This callback will occur just after an existing record in a table is deleted by a call to JetDelete. | |
| UserDefinedDefaultValue | This callback will occur when the engine needs to retrieve the user defined default value of a column from the application. This callback is essentially a limited implementation of JetRetrieveColumn that is evaluated by the application. A maximum of one column value can be returned for a user defined default value. | |
| OnlineDefragCompleted | This callback will occur when the online defragmentation of a database as initiated by JetDefragment has stopped due to either the process being completed or the time limit being reached. | |
| FreeCursorLS | This callback will occur when the application needs to clean up the context handle for the Local Storage associated with a cursor that is being released by the database engine. For more information, see JetSetLS. The delegate for this callback reason is configured by means of JetSetSystemParameter with JET_paramRuntimeCallback. | |
| FreeTableLS | This callback will occur as the result of the need for the application to cleanup the context handle for the Local Storage associated with a table that is being released by the database engine. For more information, see JetSetLS. The delegate for this callback reason is configured by means of JetSetSystemParameter with JET_paramRuntimeCallback. |
