Re: Sum of columns

[Chris Curvey <chris@xxxxxxxxxxxxxxx>]

does 

       sum (case when lev >= 50 then 1 else 0 end) as matches

do what you want?

Hi, 

 

this is my query:

SELECT user,

        sum(CASE WHEN lev >= 50 AND lev < 70 THEN 1 ELSE 0 END) as a,
        sum(CASE WHEN lev >= 70 AND lev < 80 THEN 1 ELSE 0 END) as b,
        sum(CASE WHEN lev >= 80 AND lev <= 90 THEN 1 ELSE 0 END) as c,

        sum(CASE WHEN lev > 90 THEN 1 ELSE 0 END) as d,
        (SELECT a + b + a + d) AS matches
        FROM t_temp_fts 
        GROUP BY user'

 

I like to add up the 4 columns a,b,c and d of every user, but it doesn't work like this.

Does anyone know a solution
