I have quotes and quotes have items.

When i duplicate a quote i need to also duplicate the items.

I have achieved this in one instance with the following. 

    $sql2 = "INSERT INTO quote (client_id, total_value, job_id, version, name, currency, kit_delivery, kit_return, quote_status_id)
            SELECT client_id, total_value, job_id, (version+1), name, currency, kit_delivery, kit_return, 2 from quote where quote.id = :quoteId";
    $stmt2 = $pdo ->prepare($sql2);
    $stmt2 -> execute([
        ":quoteId" => $quoteId
    ]);
    $iid = $pdo -> lastInsertId();

This works but the version + 1 that i have in there is not going to work as i first need to check for the highest version that has been used.

I may have gone down a rabbit hole here however: 

function createNewQuoteFromThisVersion($quoteId){
    include 'includes/dbconn.php';
    $sql ="UPDATE quote SET quote_status_id = 1";
    $stmt = $pdo ->query($sql) -> execute();

    $sql4 = "SELECT client_id, job_id from quote where id = :quoteId";
    $stmt4 = $pdo -> prepare($sql4);
    $stmt4 -> execute([
        ':quoteId' => $quoteId
    ]);
    if($row = $stmt4 -> fetch()){
        $clientId = $row['client_id'];
        $jobId = $row['job_id'];

    }

    $sql5 = "SELECT max(version) as v from quote where client_id = :clientId and job_id = :jobId";

    $stmt5 = $pdo -> prepare($sql5);
    $stmt5 -> execute([
        ':clientId' => $clientId,
        ':jobId' => $jobId
    ]);
    if($row = $stmt5 -> fetch()){
        $versionNumber = $row['v'];

    }

    $sql2 = "INSERT INTO quote (client_id, total_value, job_id, version, name, currency, kit_delivery, kit_return, quote_status_id)
            SELECT client_id, total_value, job_id, :version, name, currency, kit_delivery, kit_return, 2 from quote where quote.id = :quoteId";
    $stmt2 = $pdo ->prepare($sql2);
    $stmt2 -> execute([
        ":quoteId" => $quoteId,
        ':version' => $versionNumber
    ]);
    $iid = $pdo -> lastInsertId();

    $sql3 = "INSERT INTO quote_items (quote_id, item_id, quantity, start_date, end_date, notes, amount_charged_each, original_price, chargable_units)
            SELECT :iid, item_id, quantity, start_date, end_date, notes, amount_charged_each, original_price, chargable_units from quote_items where quote_id = :quoteId";
    $stmt3 = $pdo -> prepare($sql3);
    $stmt3 -> execute([
        ':iid' => $iid,
        ':quoteId' => $quoteId
    ]);
}

This was my effort at doing what i needed to.

The sql2 section is where i am going wrong i think.  What is the correct way to select what is in the database but also amend the some of the data you are putting in.

I can give data here if needed.

Please forgive the naming convention here it will be tidied as i go.

Start with 

SELECT q.id
     , q.version
FROM quote q
     JOIN (
            SELECT client_id
                 , max(version) as version
            FROM quote
            WHERE client_id = 15
          ) latest USING (client_id, version);
          
+----+---------+
| id | version |
+----+---------+
| 71 |       6 |
+----+---------+

Now you know that for client #15 the latest quote has id = 71 and its version is 6.

Duplicate quote #71, giving the dupe a verion of 7, and duplicate the items for #71 with the quote_id of the new duped quote.
