set/reset user defined properties via db query

[lazyeye]

Hi,

I'm trying to figure out a way to change the values of some properties via a database query. I need to change the values of 2 properties for ALL products in the catalog, and doing that via actinic is just WAY too long. There're the variable and userdefinedproperties tables in the actiniccatalog db, but they're just dealing with variable settings, definitions, and parameters. I'm trying to find the relationships, how those properties relate to a product. This relationship must be somewhere. If I can find it then I can build a query which I'll be using to change whatever value either globally or according to some conditions.
Understand what I mean?

You can usually do this by changing their placement and then changing it back.

"changing their placement"?? What, like, moving them around?
