If you are building an extension based on Extbase/Fluid you can find the 
experts in the newsgroup/mailinglist typo3.projects.typo3v4mvc

I assume that you are building an extension based on pibase (the 'old' 
way ;-) ). From your description it seems that you want to present a 
list of records (products) and that some of them are visible for certain 
FE users and others are visible for other FE users.

If that is the case you can simply use the access fields of TYPO3. Make 
sure you have the access field where you can select the FE usergroup 
which has access to a record enabled in your configuration of the 
products table.

In your SQL query you can simply add 
$this->cObj->enableFields('tx_myproductstable'); to the where part. This 
will add things like hidden='0', disabled='0' (if they are configured 
for that table) and also a check for the right fe_group.

Example:
$products = $GLOBALS['TYPO3_DB']->exec_SELECTgetRows(
   '*',
   'tx_myproductstable',
   'column1=' . intval($var) .
     $this->cObj->enableFields('tx_myproductstable')
);

This will automatically give the list of records which are not hidden or 
deleted and visible for the fe_group(s) the currently logged in user 
belongs to.
