Question

I would like to update multiple columns in my table using a case statement, but I cannot find how to do this (is this even possible). I came up with the following invalid reference query:

UPDATE tablename SET
    CASE name
        WHEN 'name1' THEN col1=5,col2=''
        WHEN 'name2' THEN col1=3,col2='whatever'
        ELSE col1=0,col2=''
    END;

Is there any way of achieving the expected result with valid SQL?

Answer 1

UPDATE tablename
SET col1 = CASE WHEN name = 'name1' THEN 5 
                WHEN name = 'name2' THEN 3 
                ELSE 0 
           END
 , col2 = CASE WHEN name = 'name1' THEN '' 
               WHEN name = 'name2' THEN 'whatever' 
               ELSE '' 
          END
;
