<p class=MsoNormal>Hello everyone,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’m having a bit of an issue with executing a
subquery. I need to find all of the items whose IDs are not in a
particular set. If I obtain the set before-hand by executing the query
that retrieves the set, then it works; if I try to execute the query that
retrieves the set as a subquery, then it doesn’t work (SQLException,
column not found).<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>For example:<o:p></o:p></p>

<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Works. There’s gotta be something simple that I’m
doing wrong here. Any help would be appreciated!<o:p></o:p></p>
