This is PHP4 Code!
Using IN Within A Normal SELECT Query
You can select from within another tables results really easily like this:
SqlCommand1->CommandText = "SELECT ProjectId \
FROM tblMyTable1 \
WHERE ProjectIsActive='TRUE' AND ProjectId IN (SELECT ProjectId FROM tblMyTable2 WHERE ProjectUsersAll='TRUE' OR UserId=@UserId) \
ORDER BY ProjectStartDate DESC";
Simple Find Name From Another Table By Matching An ID Between The Tables
$sql = "SELECT table1.name, table2.member_id FROM table1, table2 WHERE table2.member_id = $member_id AND table1.common_value = table2.common_value ORDER BY table1.name ASC";
$result = @mysql_query($sql);
$names_list = '';
while ($result = @mysql_fetch_array($result))
{
$names_list .= $result['name'] . "<br />";
}
