kalster Posted June 21, 2013 Share Posted June 21, 2013 i need to change only one field by swap and keep the rest of the values for those rows. for example, x in row one has a value of 2 and the x in the other row has a value of 3. i need to swap only x for those rows. UPDATE swap_test SET x=(@temp:=x), x = y, y = @temp; Quote Link to comment Share on other sites More sharing options...
Barand Posted June 21, 2013 Share Posted June 21, 2013 Use the rows' primary keys to identify which x should get which value Quote Link to comment Share on other sites More sharing options...
