Question

我使用下面的SQL查询形成了下表。

STATE  count(goo)  AVG_SAL  count(SCOPE)  AVG_SAL  count(FB) AVG_SAL count(PAL)  AVG_SAL
KN        1          5500        --            --          --     --        --         --
IN       --           --          1           6000        1        3999     --         --
AR        1          7000         --            --         1       8250      --        --
CL        1          6000        --             --       --          --       1      4500

SELECT
  state,
  GooCount,
  GooCount   / Total AS AVG_GOO,
  sCOPECount,
  SCOPECount / Total AS AVG_SCOPE,
  FBCOunt, 
  FBCount    / Total AS AVG_FB,
  PALCount,
  PALCount   / Total AS AVG_PAL
FROM
(
    select
      state,
      SUM(CASE WHEN COMPANY_NAME = 'GOO'   THEN 1 ELSE 0 END) AS GooCount, 
      SUM(CASE WHEN COMPANY_NAME = 'SCOPE' THEN 1 ELSE 0 END) AS SCOPECount, 
      SUM(CASE WHEN COMPANY_NAME = 'FB'    THEN 1 ELSE 0 END) AS FBCount, 
      SUM(CASE WHEN COMPANY_NAME = 'PAL'   THEN 1 ELSE 0 END) AS PALCount,    
      COUNT(*) AS total
    from company_details 
    where company_status = 'OPEN'
    group by state order by state
) AS sub;

但是我想形成这样的输出。

STATE  count(goo)  AVG_SAL  count(SCOPE)  AVG_SAL  count(FB) AVG_SAL count(PAL)  AVG_SAL
KN        1          5500        --            --          --     --        --         --
IN       --           --          1           6000        1        3999     --         --
AR        1          7000         --            --         1       8250      --        --
CL        1          6000        --             --       --          --       1      4500
Total    3           18500        1             6000        2      12249     1        4500

我想做一个明智的计数。
