Not Displaying Results with Inner Join 3 Tables

Question

I am trying to inner join 3 tables that is from OS TICKET Database.

The code I am using is $qry = "SELECT qbcd_user_email.address, qbcd_user_email.user_id FROM qbcd_user_email INNER JOIN qbcd_user ON qbcd_user.id = qbcd_user_email.user_id INNER JOIN qbcd_ticket ON qbcd_ticket.user_id WHERE (qbcd_user_email.address = '.$email.') ORDER BY qbcd_ticket.ticket_id DESC";

Code is returning:

string(287) "SELECT qbcd_user_email.address, qbcd_user_email.user_id FROM qbcd_user_email INNER JOIN qbcd_user ON qbcd_user.id = qbcd_user_email.user_id INNER JOIN qbcd_ticket ON qbcd_ticket.user_id WHERE (qbcd_user_email.address = '.patrick.kershner@gmail.com.') ORDER BY qbcd_ticket.ticket_id DESC"

but it is not displaying anything in the while clause:

while ($row = mysqli_fetch_assoc($result)){
echo $row['qbcd_ticket.number]."<br>";} 

I am not sure what is going on, or why its not displaying the results.

Can someone check out my code above and verify?

Answer 1

尝试将数字添加到您选择的属性中

$qry = "SELECT qbcd_user_email.address, qbcd_user_email.user_id, qbcd_ticket.number FROM qbcd_user_email INNER JOIN qbcd_user ON qbcd_user.id = qbcd_user_email.user_id INNER JOIN  qbcd_ticket ON qbcd_ticket.user_id WHERE (qbcd_user_email.address = '.$email.') ORDER BY qbcd_ticket.ticket_id DESC"

Answer 2

the first table is:

qbcd_ticket:
rows:

ticket_id | number | user_id | user_email_id | status_id | dept_id | and more...
5     |  762086|   2     |      0    |      1|  1  |    


the next is qbcd_user_email
rows:
id | user_id | flags | address
2  |    2    |  0    |  example@demo.com

the last is: qbcd_user
id | org_id | default_email_id | status | name              | created             | updated 
2  |    0   |   2          |     0  |  Patrick Kershner | 2017-03-03 10:44:28 | 2017-03-03 10:44:28

The information that I need to display, is all corresponding Tickets associated with the customer where it = the email address.

the only static variable that will not change is $_SESSION['user_email']; which is logged by logging into the members area.
