I have two tables.
Table "data" has three fields, "id integer", "project text", and "component text".
Table "participants" has two fields, "id integer" and "username text".
The id in each table correspond to the same thing.
The values for each table is as follows:
data
----
1 | Stocks | Decisions
2 | Stocks | Loss
3 | Stocks | Profits
4 | Bonds | Interest
participants
------------
1 | George
1 | Harry
1 | Carmen
2 | Owen
2 | John
3 | Harry
4 | Bubba
What I want is a distinct list of id, project, and component where username = Harry.
Resulting in the following:
1 | Stocks | Decisions
3 | Stocks | Profits
Can this be done in a single SQL statement?
