Question

i’m trying to match a “userTypeId” in the “users” table to its corresponding “id” in the “userRoles” table so that I can echo the “roleName”, also in “userRoles”.

Here are the tables:

userRoles
---------------------
id  roleName
1   superuser
2   admin
3   editor
4   author
5   contributor
6   subscriber

users
---------------------
id  userName        userTypeId
1   heyjohnmurray   1
2   admin           2

I tried this query and whenever i check it, it echoes out “WRONG”

$roleQuery = "SELECT id, roleName, userTypeId FROM userRoles JOIN users ON id=userTypeId";
$roleResult = mysqli_query($dbconnect, $roleQuery);

if(!$roleResult){
    echo 'WRONG';
} else {
    echo 'RIGHT';
}

Answer 1

add an ALIAS on the tables,

SELECT a.id, a.roleName, b.userTypeId 
FROM   userRoles a, users b
WHERE  a.id = b.userTypeId

or better use the format (ANSI SQL-92)

SELECT a.id, a.roleName, b.userTypeId 
FROM   userRoles a
       INNER JOIN users b
          ON a.id = b.userTypeId
