Question

I wanted to access two tables in mysql and want to use the fields in both tables. I used a innerjoin to match both tables, but wondering how to fetch the field in both tables, coz both tables are having same field name and different values.
Here is my query…

$query1 = mysql_query("SELECT facilitator.FacID, facilitator.email, assigned.email FROM facilitator INNER JOIN assigned ON facilitator.FacID = assigned.FacID WHERE assigned.email = '$stuemail' AND facilitator.active = '1'") or die($query."<br/><br/>".mysql_error());
            while($line1=mysql_fetch_array($query1,MYSQL_ASSOC)){
                $faci= $line1['FacID'];
                $facemail = $line1['email'];
                $stumail2 = $line1['email'];
.............code goes on.............. 

I want to fetch both emails field values but wondering how to do. I am sure what I have wrote for $stumail2 is wrong. Please help me.

Answer 1

You have a few options.

The first would be to assign a field-alias in MySQL:

SELECT
    facilitator.FacID,
    facilitator.email AS facilitatorEmail,
    assigned.email AS assignedEmail
    ....

The second, since you’re using mysql_fetch_array(), is to access the fields by their index. The facilitator.email field has index 1 and assigned.email has index 2, so you could use:

$facemail = $line1[1];
$stumail2 = $line1[2];

Alternatively, by default, MySQL should be adding an incremental number (starting at 1) for each duplicate column name. So, you should be able to use email1 to access the assigned.email column:

$facemail = $line1['email'];
$stumail2 = $line1['email1'];
