umm when i declare a unique constraint on 2 fields in a table like so
unique (col1,col2),
if i insert data into the table will it check them individually or as a
composite?
for example if i inserted the values
col1 | col2
1, A
1, B
2, B
2, A
if the above unique constraint is declared will it give me errors when
inserting?
neither col1 or col2 are a primary key but together they could be
considered a composite candidate key pair
