I have two tables that contain device lists. One table contains all the critical devices. The other table contains devices with comments. I am trying to retreive the list of devices without comments in a grid. I have tried the right and left joins and do not get the results I am expecting.
Here is the sql that the gui created:
SELECT devname, name
FROM devcriticaldailylist INNER JOIN devcritical ON
devcriticaldailylist.name <> devcritical.devname;
This returns the total list with comments. I need the devices without comments - the devices listed in the daily table. Anyone have an idea?

A better description of the tables and what 'comments' are would be
necessary to give an answer.

Try
SELECT devname, name
FROM devcritical
LEFT JOIN devcriticaldailylist ON devcriticaldailylist.name = devcritical.devname
WHERE devcriticaldailylist.name Is Null;
