Description
Provides access to the callback function that executes for every SQL command passed to or from the server.
Read TraceCallbackEvent to determine whether the SQL connection is monitoring communication between the application and the SQL server to which it connects. For example, if the application uses a TSQLMonitor component, that component assigns a value to TraceCallbackEvent, which it uses to monitor SQL commands. Changing the value of the callback would then interfere with the operation of the TSQLMonitor component.
TraceCallbackEvent is a read-only property. To assign a callback for monitoring SQL commands, use the SetTraceEvent method.
