user634381 :


Hi all,

I require a query. My issue is:

I have a table with 3 columns:

1'st column stores the value through (Sun, Mon,..., Sat) : All 7 days of the week.
2'nd Column stores Group_id like (1,2,...n)
3'rd Column stores Batch id like (1,2,3,....n)

Rows resemble like this:

Sun 1 1
Sun 1 4
sun 1 5
Sun 2 2
sun 2 8
Sun 2 9
Mon 1 1
Mon 1 4
Mon 1 5
Mon 2 2
Mon 2 8
Mon 2 9.
.
.
Sat 2 9

Conditions:
1. The group and batch id is the same for all the days. Eg.
Sun 1 1
Sun 1 4
sun 1 5
Sun 2 2
sun 2 8
Sun 2 9
Mon 1 1
Mon 1 4
Mon 1 5
Mon 2 2
Mon 2 8
Mon 2 9

My requirement is:

1. I want to display the distinct batch ids of the list for all the days based on group like:
1,4,5 and should not contain : 2,8,9
