For more information about how primary key information is added to a <see cref="T:System.Data.DataTable" />, see <see cref="M:System.Data.IDataAdapter.FillSchema(System.Data.DataSet,System.Data.SchemaType)" />.To function properly with the .NET Framework Data Provider for OLE DB, <see langword="AddWithKey" /> requires that the native OLE DB provider obtains necessary primary key information by setting the DBPROP_UNIQUEROWS property, and then determines which columns are primary key columns by examining DBCOLUMN_KEYCOLUMN in the IColumnsRowset. As an alternative, the user may explicitly set the primary key constraints on each <see cref="T:System.Data.DataTable" />. This ensures that incoming records that match existing records are updated instead of appended. When using <see langword="AddWithKey" />, the .NET Framework Data Provider for SQL Server appends a FOR BROWSE clause to the statement being executed. The user should be aware of potential side effects, such as interference with the use of SET FMTONLY ON statements. For more information, see SET FMTONLY (Transact-SQL).</summary>
