Certainly! Based on your requirements, here's an updated code snippet that performs the sum and subtraction of two fields with conditions applied:
php$select = $adapter->select()
->from(
['c' => $tableName],
[
'*',
'sum_field' => new \Zend_Db_Expr('c.qty + c.sale_qty'),
'diff_field' => new \Zend_Db_Expr('c.qty - c.sale_qty')
]
)
->where('c.qty > ?', $qtyThreshold) // Apply a condition on c.qty field
->where('c.sale_qty > ?', $saleQtyThreshold); // Apply a condition on c.sale_qty field
In the above code, I've added two new aliases, sum_field and diff_field, to represent the sum and subtraction of qty and sale_qty fields, respectively. Additionally, I've included conditions on both qty and sale_qty fields using the where() method. Please replace $qtyThreshold and $saleQtyThreshold with your desired values for the conditions.
Make sure to replace $adapter with your database adapter instance and $tableName with the actual name of the table you are querying.
After executing the select query, you can retrieve the result using the aliases sum_field and diff_field from the query result.
