Just had another thought on this problem (a lot like bad gas, I guess).  Are we talking about attachment views here?

Nan wich has a good idea about the learning process, does she do training?  As to adding a column, each round trip to the DB server is somewhat costly, if you can anticipate the extra column or columns, and include them in your first query, generally the results will be faster if done in one request, even when transferring additional data, up to a point of course.  One bonus of doing this is you could create “fly over” pop-ups, although it won’t take much to eat up the savings from your combined query, with all the generated html.

The other approach is to have the popup retrieve the extra content just for the popup page, much like with ajax, except you could just retrieve the extra page (don’t do a fly over popup if you take this approach, you’ll beat your server to death).

Hi All

In my custom module, I do a SQL query. After the query is done, I want to add a coulmn to query result.

In that new coulmn I wan to put a "Details" link, if user clicks on "Details" link, user should be able to see a new pop-up dialog page containing more data about the searched record. 

Is it possible, please suggest how it can be done.

Best Regards

Austin
