Hi!

I need some help how to compare values from a table with a csv string.

1. I have a SP that takes a CSV string.
2. I need to check so the values from a SELECT in the SP  exists in the CSV string

The problem is that some values in the table must exists in the csv string but there are also values that are grouped, and just one of theses values needs to be found in the csv string.

EX:
CSV string
'foo1', 'foo2', foo3', 'foo5'

SELECT Query in SP will return
C1_Value     C2_Group
foo1             1
foo2             2
foo3             3
foo4             3
foo5             4

foo3 and foo4 are in the same group => OR between these values

SQL SP should verify:
is table value 'foo1' in csv string AND
is table value 'foo2' in csv string AND
is table value  ('foo3' OR 'foo4')  in csv  string AND
is table value 'foo5' in csv string

if true return 1 if false return 0

Any tips?
