I have three table in my Database.  Email, enrollees and users.

Please view attached picture to get a better understanding.  I need to retrieve the 'official_email' data field from the  'enrollees' table.  I have the following code but it missing the select statement to where = select ....

I have this case.  Into my code the Enrolle id_number is 972432 is not equal to the client.user_id which is 16885.  How I can retrieve the 'official email' data from that field into the 'enrollees' table??

<CFQUERY NAME="DisplayEmail" datasource="aar" username="#application.username#" password="#application.password#">
    SELECT official_email
      FROM enr
    WHERE enrollee_id_number  = #client.user_id#

</CFQUERY>

Please advise, how I can add another select to the where = select .... .

If you must match on user id, you need a JOIN between user and enrollees.  Assuming the "user_id" column is an INTEGER, something like this where #someUserIDHere# represents the user id, ie 16885

(Always use cfqueryparam to protect the db from sql injection)

SELECT e.official_email
FROM   Users u INNER JOIN Enroless e ON e.enrollee_id_number = u.id_number
WHERE  u.user_id = <cfqueryparam value="#someUserIDHere#" cfsqltype="cf_sql_integer">

Right now into my code I have this script.

<CFQUERY NAME="DisplayEmail" datasource="aar" username="#application.username#" password="#application.password#">
    SELECT *
    FROM email
    WHERE email.user_id = #client.user_id#
    </CFQUERY>

Open in new window


<td height="21">E-Mail:</td>
              <td height="21"><cfoutput>
             <input type="text" name="email" value="#DisplayEmail.email#" size="50">

Based on these tables attached, please do you know how to change that cfquery?

Thank you very much for your help!!!

If you want to use official_email instead of "email",  use the query I posted.  But substitute #client.user_id# for #someUserIDHere#.  

<CFQUERY NAME="DisplayEmail" datasource="aar" username="#application.username#" password="#application.password#">
SELECT e.official_email
FROM   Users u INNER JOIN Enroless e ON e.enrollee_id_number = u.id_number
WHERE  u.user_id = <cfqueryparam value="#client.user_id#" cfsqltype="cf_sql_integer">
</cfquery>

Also change the query column name in the output:

<input type="text" name="email" value="#DisplayEmail.official_email#" size="50">

Here is what I've received.

I have this on line 69:

My bad. Looks like there's a typo in the table name. Just correct it by plugging in the real name of your enrollees table here:

...
FROM   Users u INNER JOIN Enrolless e ON e.enrollee_id_number = u.id_number
...
