Question

I have a table RECEIPT and the ID that i created is

REC-201290001 = “REC-“+”YEAR”+”MONTH”+”0001”

I create the number with a String.Format but in order to create the next one i need the last ID i inserted so i can increase it.

Thanks very much for your help.

$query = mysql_query("select value from config where name = 'next_receipt_id'");
$row = mysql_fetch_assoc($query);
$receiptId = "REC-"+"YEAR"+"MONTH"+$row['value'];

$insert_query = mysql_query("INSERT into order (`id`,...) values($receiptId,...)");

$updateReceiptId = mysql_query("update config set value = value+1 where name = 'next_receipt_id');
