Question

My table is,

 customdata check service loc value
  101        0    0        4   4
  101        0    0        3   3
  101        5     4       4    3
  102        0     0       1     2
  102        4     4       3     3
  103        0     0       4     4

My result should be like,

  customdata cnt splcnt//count of check when not 0
   101        3    1
   102        2    1
   103        1    0

Can anyone tell me how should i have my query to take this both this count.

Answer 1

Use a CASE statement to conditionally SUM based on the value of check:

SELECT
    customdata,
    COUNT(*) AS cnt,
    SUM(CASE WHEN check > 0 THEN 1 ELSE 0 END) AS splcnt
FROM YourTable
GROUP BY customdata
