campaign table are the item for sale and on the transaction table are the item sold. I want to count the transaction_id that are made transaction table and sum the total of sold item.. but the table are different..
Here is what I tried:
$uid = $_GET['uid']; $query = " SELECT transaction.*, count(*) AS transaction.transaction_id, sum(*) AS campaign.payout FROM transaction JOIN transaction.c_id=campaign.c_id GROUP_BY c_id WHERE uid=$uid AND DATE(dateTime)=DATE(NOW())"; $result = mysqli_query($conn, $query); while ($row = mysqli_fetch_assoc($result)) {$transaction_id = $row['transaction_id']; $payout = $row['payout'];} echo "payment: [".$payout."] transaction: [".$transaction_id."]";
campaign table:
------------------------ |c_id | c_name | payout| ----------------------- | 1 | c_n1 | 100 | | 2 | c_n2 | 200 | | 3 | c_n3 | 300 | ------------------------
transactions table:
-------------------------------- |transaction_id | c_id | valid | -------------------------------- | 12325sdfsf3 | 1 | 1 | | 324ssggsgs3 | 1 | 1 | | f2fs33fs3sg | 3 | 1 | --------------------------------

Answer
To get the total payout for all transactions you need to perform a join. For example:
select count(*) as total_count, sum(c.payout) as total_payout from transaction t join campaign c on c.c_id = t.c_id
The SUM()
function will add up all values from the payout
column.
