I have gotten far enough to get the table onto vinilla (for my extension) but I am clueless on how to manage and display it, can someone please explain this to me?

Lets say I want to add to the comment query so that it will check to see if the users ID matches up the commentors ID.

Lets say I want to make a query from scratch what do I do?

    Do you know any mysql whatsoever or are you just unsure how to use the sqlbuilder class that vanilla uses?

    There are lot's of examples in the libray/Vanilla folder. But basically you use these methods:

    Create a new instance of the SqlBuilder class:
    $s = $Context->ObjectFactory->NewContextObject($Context, 'SqlBuilder');

    Set the main table of which you want to retrieve data. Use 'd' as an alias:
    $s->SetMainTable('Discussion', 'd');

    Add some fields to the select statement you want, again specify the alias:
    $s->AddSelect(array('DiscussionID', 'Name'), 'd');

    Now we add a where-statement and an order by property:
    $s->AddWhere('d', 'DiscussionID', '', '10', '<'); $s->AddOrderBy('DiscussionID', 'd');

    Finally, to retrieve the data, use the Database object:
    $ResultSet = $Context->Database->Select($s, 'Name of your class', 'Function where this query is triggered', 'Some error information');

    The result can be looped through by using:
    while ($row = $Context->Database->GetRow($ResultSet)) { echo $row['Name'] . '<br />'; }

    But again.. if you want to learn it, just browse through the vanilla files, or take a good look at the SqlBuilder class ;)
