I have a successful select query, where I'm looping and building a row for getting parameters which works correctly while ($row = $orderDetailCheck->fetch(PDO::FETCH_ASSOC)) { $params = [ ":INVOICE_NUMBER" => $row["INVOICE_NUMBER"], ":CUSTNM" => $row["CUSTNM"], ":SELLINGN" => $row["SELLINGN"], ":GROUP" => $row["GROUP"], ":DTL12" => $row["DTL12"], ":DTL13" => $row["DTL13"], ":QUANTITY" => $row["QUANTITY"], ":COUNT_PLMN_1" => $row["COUNT_PLMN_1"], ":LAST_DATE" => $row["LAST_DATE"], ]; } My issue now is that, for each row, I need to perform two merges because the data from that select is going to be split into two tables in db2. Some values are truly split between the tables but some values are shared between the two. I'm not sure the best way to perform these two merges because if the first one (products table) inserts, then it creates an ID that I need as a foreign key basically, to insert into the orders table. So on insert I need to grab that newly created ID and use it for ```product_id``` in the second merge. If the first merge performs the update when matched, then I need to grab the existing ID for that record so that I can update the proper record in the orders table. My two merge statements: /*products table*/ MERGE INTO products AS P USING(VALUES( :GROUP, :DTL12, :DTL13, :CUSTNM, :SELLINGN, :COUNT_PLMN_1, :LAST_DATE ) ) AS S(GROUP,DTL12,DTL13,CUSTNM,SELLINGN,COUNT_PLMN_1,LAST_DATE) ON s.GROUP = p.GROUP and s.DTL12 = p.DTL12 and s.DTL13 = p.DTL13 and s.CUSTNM = p.CUSTNM WHEN MATCHED THEN UPDATE SET LAST_DATE = s.LAST_DATE WHEN NOT MATCHED THEN INSERT VALUES (s.GROUP,s.DTL12,s.DTL13,s.CUSTNM,s.SELLINGN,s.COUNT_PLMN_1,s.LAST_DATE) /*ORDERS Table*/ MERGE INTO ORDERS AS PO USING(VALUES( /*need foreign key, which is id from products table*/ :QUANTITY, :LAST_DATE, :INVOICE_NUMBER )) AS S(PRODUCT_ID,quantity_ordered,LAST_DATE,invoice_number) ON s.PRODUCT_ID = po.id WHEN MATCHED THEN UPDATE SET LAST_DATE = s.LAST_DATE, quantity_ordered = s.quantity_ordered, invoice_number = s.invoice_number WHEN NOT MATCHED THEN INSERT VALUES (s.PRODUCT_ID, s.quantity_ordered, s.LAST_DATE, s.invoice_number) Examples: If my ROW Returns INVOICE | CUSTNM | SELLINGNUM | GROUP | DTL12 | DTL13 | QUANTITY | COUNT_PLMN_1 | LAST_DATE ================================================================================================================== 1122 123 321 995 1452 12 13 5 '2018-12-14' Then my insert into products would be products ID | GROUP | DTL12 | DTL13 | CUSTNM | SELLINGNUM | COUNT_PLMN_1 | LAST_DATE ========================================================================================================== 1 995 1452 12 123 321 5 '2018-12-14' and my insert to orders: ORDERS PRODUCT_ID | QUANTITY_ORDERED | LAST_DATE | INVOICE ============================================================ 1 13 '2018-12-14' 1122 But if my next record matched on my unique qualities with a new invoice, quantity and date ROW Returns INVOICE | CUSTNM | SELLINGNUM | GROUP | DTL12 | DTL13 | QUANTITY | COUNT_PLMN_1 | LAST_DATE ================================================================================================================== 1133 123 321 995 1452 12 4 5 '2018-12-18' Then I would update products like so: products ID | GROUP | DTL12 | DTL13 | CUSTNM | SELLINGNUM | COUNT_PLMN_1 | LAST_DATE ========================================================================================================== 1 995 1452 12 123 321 5 '2018-12-18' and update orders like so: ORDERS PRODUCT_ID | QUANTITY_ORDERED | LAST_DATE | INVOICE ============================================================ 1 4 '2018-12-18' 1133 I guess the main question is: How can I get the ID of a record from the products table (whether it's an existing match OR newly created in the merge) and once I get it, how can I use it for the 2nd merge?

This is what I am trying to accomplish. 1. I have two tables. T1: Users and T2: Earnings. 2. I want to find a single random user whose deposit amount is greater than the listed amount. Below is my foreach loop within foreach loop trying to do the above. I was wondering if there is a more simple way to do this task? Is there a way to combine these two queries together? $listed_amount = 1000; // find a random user $find_user = $db->prepare("SELECT user_id FROM users WHERE user = :user AND active = :active ORDER BY RAND() LIMIT 1"); $find_user->bindValue(':user', 1); $find_user->bindValue(':active', 1); $find_user->execute(); $result_user = $find_user->fetchAll(PDO::FETCH_ASSOC); if(count($result_user) > 0) { foreach($result_user as $row) { $user_id = $row['user_id']; // find that random user's deposit amount $get_deposits = $db->prepare("SELECT deposit FROM earnings WHERE sent_to = :sent_to AND status = :status"); $get_deposits->bindParam(':sent_to', $user_id); $get_deposits->bindValue(':status', 1); $get_deposits->execute(); $result_deposits = $get_deposits->fetchAll(PDO::FETCH_ASSOC); if(count($result_deposits) > 0) { $ub = 0; foreach($result_deposits as $key=>$row) { $ub+= $row['deposit']; } $total_deposits = $ub; } if($total_deposits > $listed_amount) { // show the user } else { // hide the user } } }
