Remarks

SqlCeCommandBuilder creates SQL statements that do not detect conflicts. This behavior differs from that of System.Data.SqlClient.

The SqlCeCommandBuilder registers itself as a listener for RowUpdating events whenever you set the DataAdapter property. You can associate only one SqlCeDataAdapter or SqlCeCommandBuilder object with each other at one time.

To generate INSERT, UPDATE, or DELETE statements, the SqlCeCommandBuilder uses the SelectCommand property to retrieve a required set of meta data automatically. If you change the SelectCommand after the meta data has been retrieved (for example, after the first update), you should call the RefreshSchema method to update the meta data.

The SelectCommand must also return at least one primary key or unique column. If there is none present, an InvalidOperation exception is generated, and the commands are not generated.

The SqlCeCommandBuilder also uses the Connection and Transaction properties referenced by the SelectCommand. You should call RefreshSchema if any of these properties are modified, or if the SelectCommand itself is replaced. Otherwise, the InsertCommand, UpdateCommand, and DeleteCommand properties retain their previous values.

If you call Dispose, the SqlCeCommandBuilder is disassociated from the SqlCeDataAdapter, and the generated commands are no longer used.
