Depends... Looking at what you posted it'll be something like this:
SELECT DISTINCT $table_sport.sportID
FROM $table_sport, $table_users
WHERE $table_users.usrName = '$admin_username'
AND $table_users.usrPswd = password($admin_password)
AND $table_sport.usrName = $table_users.usrName
AND $table_sport.usrPswd = $table_users.usrPswd
You can also make it a bit more readable, like this:
SELECT DISTINCT S.sportID
FROM $table_sport S,
$table_users U
WHERE U.usrname = '$admin_username'
AND U.usrPswd = password($admin_password)
AND S.usrName = U.usrname
AND S.usrPswd = U.usrPswd;
This way you don't have those variablenames in the query all the
time.
