MySQL: Simple way to toggle a value of an int field

Question

I know how to do this, but i think I\'ll overcomplicate it with double selects and so on.

How can you do this (example in pseudo-sql)

UPDATE some_table S         


        

Answer 1

In this case, you could use an XOR type operation:

UPDATE some_table SET an_int_value = an_int_value XOR 1

This is assuming that an_int_value will always be 1 or 0 though.
