Function PreparedImpl.queryRow

Execute a prepared SQL SELECT command where you only want the first Row (if any).


					
			std.typecons.Nullable!(mysql.result.Row) queryRow
			(
			

			  ColumnSpecialization[] csa = null
			

			);

If the SQL command does not produce a result set (such as INSERT/CREATE/etc), then MYXNoResultRecieved will be thrown. Use exec instead for such commands.

If there are long data items among the expected result columns you can use the csa param to specify that they are to be subject to chunked transfer via a delegate.
