I have aphp code to retrieve data from multiple tables eg:

SELECT RC.customer_id, RC.customer_number, RAA.address_id, RAA.customer_id FROM apps.RA_CUSTOMERS RC, apps.RA_ADDRESSES_ALL RAA WHERE RC.customer_number = 89

However, since customer_id is in two separate tables, how do I retrieve it? For everything else, in the while() loop, I can just do

while ($row = oci_fetch_array($stid, OCI_ASSOC+OCI_RETURN_NULLS)) { $row['CUSTOMER_NUMBER']; //this works! $row['RC.CUSTOMER_ID']; //this does not ... $row['CUSTOMER_ID']; //this works, but how do I know which table is this from? }

Any help greatly appreciated!

You can just use an ALIAS like RC.customer_id AS cid and RAA.customer_id AS raa_cid .

SELECT RC.customer_id AS cid, RC.customer_number, RAA.address_id, RAA.customer_id AS raa_cid FROM apps.RA_CUSTOMERS RC, apps.RA_ADDRESSES_ALL RAA WHERE RC.customer_number = 8

Now toy can call it using

$row['cid']; //the one from RA_CUSTOMERS $row['raa_cid']; //the one from RA_ADDRESSES_ALL

As you see by placing an alias now you call them and print by using alias given
