Exception typeCondition


This property cannot be changed after an insert, update, or delete command has been generated.

Some data sources may have objects that can contain characters such as spaces, commas, and semicolons. To accommodate this capability, use the QuotePrefix and QuoteSuffix properties to specify delimiters such as a left bracket and a right bracket to encapsulate the object name.


Although you cannot change the QuotePrefix or QuoteSuffix properties after an insert, update, or delete command has been generated, you can change their settings after calling the Update method of a DbDataAdapter.
