Re: SQL Query - Using variable from another SQL Query

Try this as your SQL. It should give you all the results, then you can use PHP to sort it all out.

SELECT * FROM egw_cal WHERE cal_category='501' and cal_id in (SELECT cal_id FROM egw_cal_dates where cal_start > $tstamp)

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...

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...";



?>
