Trying to call a 10 working day attendance record of a class using GROUP_CONCAT and getting repeating values in it.

the query is

The result is not accurate. error in count of Total Present

  • Just add a DISTINCT inside GROUP_CONCAT(DISTINCT ... – Mihai May 21 '15 at 09:05

    If it was me, I'd start with the problem (the sample data set), the solution (the desired result set), and an indication of what you've tried so far to get from a to b - all presented in a way that others could easily replicate. – Strawberry May 21 '15 at 09:07

  • Actually DISTINCT is counting the total_p as 1 e.g. mon, tue, wed total_p 7:40:00, 7:40:00, 7:40:00, 1 – Atif Naseem May 26 '15 at 08:58
