Re: SQL Query - Using variable from another SQL Query

This is a join - Read up on them, they're very useful and don't require the overhead of a sub-query. SELECT egw_cal.* FROM egw_cal_dates LEFT JOIN egw_cal using (cal_id) where egw_cal_dates.cal_start > $tstamp AND egw_cal.cal_category = '501' -Micah On 02/12/2007 08:14 AM, Matthew Ferry wrote:

Hello Everyone.... Got a simple / stupid question. Worked on this all night. I'm over looking something very basic here. The query "event_time" brings back the calendar id for each event that is pending in the future. ie.... 12, 13, 14, 26 (There could be 100 of them out there) The second query "events" needs to meet both reqirements. 1 - cal_category='501' 2 - cal_id= a number from the "event_time" query I think i need to do a loop inside of a loop Thanks... Matt Here is my code: <?php $todays_year = date("Y"); $todays_month = date("m"); $todays_day = date("d"); $tstamp = mktime(0, 0, 0, $todays_month, $todays_day, $todays_year); $event_time = mysql_query("SELECT cal_id FROM egw_cal_dates where cal_start > $tstamp", $db); $events = mysql_query("SELECT * FROM egw_cal WHERE cal_category='501' and cal_id='$event_time'\n", $db); if ($event = mysql_fetch_array($events)) { echo "<center>\n"; echo "<HR>\n"; do { echo "<B><Font Size='10'>$event[cal_title]&nbsp;&nbsp;&nbsp;&nbsp;-&nbsp;&nbsp;&nbsp;$event[cal_location]</B></Font>\n"; echo "<BR>\n"; echo "$event[cal_description]"; echo "<BR>\n"; echo "<HR>\n"; } while ($event = mysql_fetch_array($events)); } else { echo "No Public Events Are Currently Scheduled..."; } ?>
