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?
