SQL query using two or more tables
I am trying to get information from my SQL to a PHP page, the problem I have is I am trying to use multiple tables to populate the result
The columns of the columns have the same names, although the table names are obviously different.
Table ticket
status_id; TICKET_ID
Ticket__cdata table p>
TICKET_ID
SELECT * FROM ticket WHERE status_id = '1' ORDER BY created DESC
I am filtering a table for only lookup 1 in table A
I am repeating TICKET_ID to php from table A, but now I want to filter ticket_id on table B and extract information from this form. Table be has no status_id so cannot filter on this again.
Logic says I should say something like this
SELECT * FROM ticket_cdata WHERE ticket_id = '".$ticket_id."'
Here is my code as of today without the second request
$result = mysql_query("SELECT * FROM ost_ticket WHERE status_id = '1' ORDER
BY created DESC");
?>
<?php
while($rows=mysql_fetch_array($result)){
?>
<tr>
<td class="center">
<div align="center"><? echo $rows['number']; ?></div></td>
<td><div align="center"><? echo $rows['ticket_id']; ?></div></td>
<td><div align="center"><? echo $rows['lbs_time']; ?></div></td> //This it the info required from TABLE ticket but must be linked to the status_id
UPDATED STRING
$result = mysql_query("SELECT tc.*
FROM ticket_cdata tc
JOIN ticket t ON tc.ticket_id = t.ticket_id
WHERE t.status_id = '1'
ORDER BY t.created DESC");
?>
<tr>
<td class="center">
<div align="center"><? echo $rows['number']; ?></div></td>
<td><div align="center"><? echo $rows['ticket_id']; ?></div></td>
<td><div align="center"><? echo $rows['created']; ?></div></td>
<td><div align="center"><? echo $rows['subject']; ?></div></td>
Now I can't Echo any info

The original query can be modified as follows:
SELECT * FROM ticket t
WHERE t.status_id = '1'
AND EXISTS (SELECT * FROM ticket__cdata WHERE ticket_id = t.ticket_id)
ORDER BY t.created DESC
This limits the results that are present in the table ticket__cdata
and have status_id = '1'
