Exceptions

Exception	Description
System.InvalidOperationException	The DataAdapter property is not set, SelectCommand of the associated TdDataAdapter is not set or no TdConnection is associated with DataAdapter.SelectCommand.
System.ObjectDisposedException	The TdCommandBuilder is closed/disposed.

Remarks

The invocation of RefreshSchema method can result in one or more calls to the Advanced SQL Engine to retrieve metadata (Column and Table information). The metadata is cached in order to minimize roundtrips to the Advanced SQL Engine. The cache is purged only when the DataAdapter property is set or the RefreshSchema method is called. Therefore, you should call RefreshSchema when there are changes the to the SelectCommand property of associated TdDataAdapter.
