Solution 2

The first rule of thumb, never concatenate values to an SQL statement. Instead use SqlParameterhttp://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlparameter.aspx[^] (if this is SQL Server, otherwise use relevant parameter class like OleDbParameter).

To your question, see: Solving the Operation Must Use An Updateable Query error
[^] or http://support.microsoft.com/kb/175168[^]
