Hi,
Do you mean that the table has two unique indices, or that the primary index
has two columns?
Either way, it is easy to define this in mysql:
create table foo (
col1 varchar(20) not null,
col2 int not null,
col3 smallint not null,
primary key(col1, col2),
unique second_idx(col1, col3));
Hope this helps
Quentin

Subject: PK, SK, FK . . . ?
Terribly simple question, but I'm fairly new at this.
I'm building a database based off a model built in MS Access. The table
that I'm currently working on appears to have two Primary Keys, although I'm
assuming one of them must be secondary. How would I specify this in
creating the table in MySQL? Would I need to create a composite key, etc.?
Thanks.
