vary the select statement in a from clause

hey all,

i have a sql like so:

update mytable
set mycol=val
if (cond)
select myval from t1
select * from t2
) tbl

is there a way to make the if(cond) work? probably doesn't look like a good 
idea anyway?

It will be best to simply use IF statement and run two separate queries based on the conditions:

IF (cond)
   UPDATE mytable ... FROM t1
   UPDATE mytable ... FROM t2

Pre-select visible sheets in listbox
Hi All, I have a user form which has a listbox which lists all the sheets in the workbook. It allows the user to pick from the list which sheets they would like to see, and hide the unselected ones. What I would like the listbox to do when the form opens, is to pre- select the sheets that are already visible, so that the user can just modify the selction instead of starting from scratch. Any help that people can give would be appreciated cheers Paul As a user, I would think that it would make more sense to ask me to select the sheets to hide--but that doesn't change ...

Selecting individual records for a report

Easier ways to selectively open a .wks as read-only...
Excel has a way via its internal file-open mechanism any worksheet as read only. This is great if you want to prevent damage to a sheet (yours or god forbid somebody elses). If you're a pathological user of Autosave like I am (to wit my related post on Autosave), you'll know how good an idea this can be. I know there are some freeware alternatives to Autosave (Autosafe, for example) but as a corporate user, I can't really use/install freeware.

Case statement vs Change/lookup table
Hello All Gurus, This is a problem that I have encountered and was wondering what would be a better approach to the solution I have a view that is pulling data from a table which is fed from an external application. Some of the data due to external situations is wrong/spelled wrong, in the past when this happened I updated another view with a complex set of case statements. This is fast and stable, however, it is for only three instances as they are the only mistakes and they happen always, aka the data is always spelled wrong for these three instances. Now there is a situation wher...
