Phalcon ExecuteQuery inner Join issues - phalcon

Question

This is Native SQL Query, thats work in MySql:
SELECT a.pshdQty
FROM production_stock_header a
INNER JOIN (SELECT MAX(pshdId) AS pshdId
FROM production_stock_header
WHERE pshdAuditDelete = 'N'
) b
ON a.pshdId = b.pshdId
But, why in Phalcon this always errors?
$triggerSet = $this->modelsManager->executeQuery("
SELECT pshdQty
FROM ProductionStockHeader
INNER JOIN (SELECT MAX(pshdId) AS pshdId
FROM ProductionStockHeader
WHERE ProductionStockHeader.AuditDelete = 'N'
) AS b
ON ProductionStockHeader.pshdId = b.pshdId
");

Answer 1

Phalcon ORM doesn't provide a way to write such join statements.
I'd suggest to just run a raw native SQL query on your db connection:
$triggerSet = $this->db->query("SELECT a.pshdQty
FROM production_stock_header a
INNER JOIN (SELECT MAX(pshdId) AS pshdId
FROM production_stock_header
WHERE pshdAuditDelete = 'N'
) b
ON a.pshdId = b.pshdId")->fetch();
$this->db points to your database connection you registered in your services.
You can also drop the inner join all together:
$triggerSet = $this->modelsManager->executeQuery("
SELECT pshdQty
FROM ProductionStockHeader
WHERE AuditDelete = 'N'
ORDER BY pshdId DESC
LIMIT 1
");
