i have the following query:
1.$query="SELECT * FROM ab_service WHERE account_id=$account_id AND sku='".$sku."'";
2.$query="SELECT * FROM ab_service WHERE account_id=$account_id AND sku='$sku'";
none of the above seems to work.the problem is with $sku var because when i dont put it as the condition, i get results.what is the problem ? the variable $sku is already asigned from another table.
