like the questioned asked... i asked because I always thought primary was just unique... wasn't sure if it was indexed

Yes it's always indexed.
You can consider a primary key being like a unique index, basically.

It can be more, but it becomes DB specific.

Yes, Indexed

in mysql a primary key is exactly like a unique index with the exception of a unique index allows null values and a primary key doesn't.

Hi,

If you have assign a primary to your database table than it will automatically indexed..
