Question

I get an error with this SUBSELECT?

$common_dimensions_query = "
SELECT *
FROM main_products_common_dimensions d
WHERE d.product_id = (SELECT id FROM main_products WHERE abbreviation = '".$product."'";

The error:

Warning: pg_query() [function.pg-query]: Query failed: ERROR: syntax error at end of input LINE 4: … (SELECT id FROM main_products WHERE abbreviation = ‘banner’ ^ in

Is there anyway to do a LEFT JOIN here instead?

Answer 1

A version with JOIN instead of double SELECT:

"SELECT *
FROM main_products_common_dimensions d
JOIN main_products p ON d.product_id = p.id
WHERE p.abbreviation = '$product'"
