RE: query help

[Jay Blanchard]

I have a table similar to this:

 -------------------------
|transactions             |
|ID   |DATE      |EMPLOYEE|
|234  |2010-01-05| 345    |
|328  |2010-04-05| 344    |
|239  |2010-01-10| 344    |

Is there a way to query such a table to give the days of the year that
employee 344 did not have a transaction?
[/snip]

SELECT DATE
FROM transactions
WHERE EMPLOYEE != '344'
GROUP BY DATE;
