MySQL update case help

Question

Can anybody tell me how to fix this query?

update ae44
set Price = Case
when ID = \'AT259793380\' then \'500\'
when ID = \'AT271729590\' then \'600\'
when ID         


        

Answer 1

UPDATE ae44 SET
    Price = CASE
    WHEN ID = 'AT259793380' THEN '500'
    WHEN ID = 'AT271729590' THEN '600'
    WHEN ID = 'AT275981020' THEN '700'
    ELSE Price END

Or you can use WHERE:

UPDATE ae44 SET
    Price = CASE
    WHEN ID = 'AT259793380' THEN '500'
    WHEN ID = 'AT271729590' THEN '600'
    WHEN ID = 'AT275981020' THEN '700'
    END
WHERE 
    ID IN ('AT259793380', 'AT271729590', 'AT275981020')

And set the LIMIT is good idea too:

UPDATE ae44 SET
    Price = CASE
    WHEN ID = 'AT259793380' THEN '500'
    WHEN ID = 'AT271729590' THEN '600'
    WHEN ID = 'AT275981020' THEN '700'
    END
WHERE 
    ID IN ('AT259793380', 'AT271729590', 'AT275981020')
LIMIT 3
