I have a table that holds 1 to many items. To keep it simple say it
has 2 columns: tagid and noteid. A given tagid can have many noteid's.
ex.
tagid   noteid
------  ------
a       1
a       4
a       7
b       7
b       3
c       1

I want to perform a query: give me all noteid's that have tagid a and
tagid b. The result for the example above would be:

noteid
------
7

Can someone point me in the right direction. I am also interested in
optimal performance here.

I'm new to SQL and so far I am just doing simple select's. Thanks.
