Query Help

[gfxhavenowner]

I posted this on VB.com, but really need help, so I'm posting it here too.

I want to run a MySQL query to set up a new variable. The variable will contain multiple forum ids separated by commas. I'm pretty new to all of the coding stuff, so here is how the variable will be stored.

$topx_omit=$DB->query_first("select * from ".TABLE_PREFIX."topx_options where oid='1'");

Now, I took this line from another hack and editted it, but if I undertsand correctly, it is a general command, so it should work.

I need to make both the table topx_options and the variable $topx_omit. Like I stated before, the variable must be able to hold multiple forum ids spearated by commas, so that I can recall the forum ids in another step. I can use either phpMyAdmin, or the VB SQL query option. How would I create this stuff?

Edit : what does oid mean, and what does oid='1' do?
