MySQL - ORDER BY values within IN()

Question

I\'m hoping to sort the items returned in the following query by the order they\'re entered into the IN() function.

INPUT:

SELECT id         


        

Answer 1

just use

order by INSTR( ',B,C,D,A,' ,  concat(',' , `field`, ',' ) )

avoid the situation like

 INSTR('1,2,3,11' ,`field`) 

will end with unordered result row : 1 and 11 alternant
