Hi,
can I habe multi table indices to ensure that certain IDs can only
appear in on relation?
Like
table_0(id int), table_1(id int), table_2(id int)
rel_1_to_0( id_1 int, id_0 int )
rel_2_to_0( id_2 int, id_0 int )
An id of table_0 should only exist either in rel_1_to_0 OR rel_2_to_0.
How can I do this?
regard
Andreas
