This is the query that i'm trying to achieve via active record:
UPDATE `Customer_donations` cd
join Invoices i on i.cd_id = cd.cd_id
set cd.amount = '4', cd.amount_verified = '1'
WHERE i.invoice_id = '13';
This is my attempt at the active record:
$data = array('cd.amount'=>$amount, 'cd.amount_verified'=>'1');
$this->db->join('Invoices i', 'i.cd_id = cd.cd_id')
->where('i.invoice_id', $invoiceId);
// update the table with the new data
if($this->db->update('Customer_donations cd', $data)) {
return true;
}
And this is the query that's actually getting produced:
UPDATE `Customer_donations` cd
SET `cd`.`amount` = '1', `cd`.`amount_verified` = '1'
WHERE `i`.`invoice_id` = '13'
Why is this active record statement not applying my join clause?
How about the solution below? A bit ugly but it achieved what you expected in your question.
$invoiceId = 13;
$amount = 4;
$data = array('cd.amount'=>$amount, 'cd.amount_verified'=>'1');
$this->db->where('i.invoice_id', $invoiceId);
$this->db->update('Customer_donations cd join Invoices i on i.cd_id = cd.cd_id', $data);
Even cleaner, since update accepts a third "where" array parameter:
$invoiceId = 13;
$amount = 4;
$data = array('cd.amount'=>$amount, 'cd.amount_verified'=>'1');
$this->db->update('Customer_donations cd join Invoices i on i.cd_id = cd.cd_id',
$data, array('i.invoice_id' => $invoiceId));
