[TYPO3-english] Using variable in $addWhere select statement

[Adrian Marcinkowski]

I have 2 extensions on different pages.

List view is rendered by extension_1

Single view is rendered by extension_2

I`m transferring a variable from list to single in url:

www.qqq.com/Index.php?tx_ext1_pi1[showUid]=388<http://www.qqq.com/Index.php?tx_ext1_pi1%5bshowUid%5d=388>



in second extension I need to add this variable to $addWhere in my select
query. How to add it do $addWhere?
