This property contains detailed information about the current notification.

Declaration

// C#
Public DataTable Details{get;}

Property Value

A DataTable instance that contains detailed information about the current notification.

Remarks

The returned DataTable object contains column data about the current notification in order as shown in Table 9-25.

The QueryId column contains the CHANGE_NOTIFICATION_QUERY_ID that corresponds to the pseudo-column that may have been retrieved by a SELECT statement at the time of the query-based notification. Also, the OracleDependency object maintains all the CHANGE_NOTIFICATION_QUERY_IDs that are registered with it.

For Continuous Query Notification:

• The Details property indicates changes for each invalidated object in the notification in the data table.

• If ROWID information is requested, then the ROWID information is populated into the Rowid column. However, if many rows are modified in a table, then the whole table is invalidated, and ROWID information is not provided. Therefore, the Rowid column contains all Null values.

• If the database event is related to a DDL change of the table or a table drop, then the Rowid column is set to Null.
