These lines: ids+=odr[0].TOString()+; ids+=odr[1].ToString() + '; // there's something wrong with this line probably a '+' was omitted Get the first column from the row convert it to a string and add it followed by a comma to the variable 'ids'. Get the second column from the row convert it to a string and add it followed by a single quote to the variable 'ids'.
