Mysql: Swap data for different rows

Question

Suppose a table fruits that looks like this:

------------------------------------------
| id |    name    |   color   | calories |
-------------         


        

Answer 1

Since ID is unique, it is difficult to just swap the IDs, it's easier to swap the column contents. A query like this might be what you need:

UPDATE
  yourtable t1 INNER JOIN yourtable t2
  ON (t1.id, t2.id) IN ((1,5),(5,1))
SET
  t1.color = t2.color,
  t1.name = t2.name,
  t1.calories = t2.calories
