Search in multi value column on SQL

Hello Experts,

I have a char(7) separated custom multi value column in ADSGroup. On a SQL level, I'm trying to get all rows which contain a particular MV attribute

For instance, if my row1 has values a;b;c and row2 has value c;d;e, then if I search for c I should get both row1 and row2, similarly if I search for 'b' I should get only row1

I believe there are some QBM_FCV functions but I'm not sure how to use those, any hints?

Thanks

Kin
