Unique indexes

i have a table which has 4 fields id, rotaId, tnt, user i want to create a unique index on the rotaId,tnt & user . I can see the unique checkbox on each field but how do i create a unique index across multiple fields?

Hi, Wappler doesn't support composite unique yet, there's a feature request if you search. Advanced users resort to creating/editing migration files manually to perform such composite unique index

Ok thanks
