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.
