  1. Taking the Column Names out of the quotes doesn't work either Also I'm new to PHP, how would I format this in PDO?
  2. I'm designing a rental service and am working on a query to see if an item is available in a certain date range So far my query is as follows $q = "SELECT SUM(quantity) AS total FROM orders, order_details WHERE orders.order_id = order_details.order_id"; $q .= " AND equip_ID =".$item['id']; $q .= " AND 'start_date' > '".$start_date."'"; $result = $db->query($q); $row = mysqli_fetch_assoc($result); $sum = $row['total']; Say for instance $start_date = 2021-03-03 the output of $q would be SELECT SUM(quantity) AS total FROM orders, order_details WHERE orders.order_id = order_details.order_id AND equip_ID =12 AND 'start_date' > '2021-03-03' This does not work but if i manually insert $q into my mysql database it works. It comes up with the error shown below when I submit it from php, but not when I do directly into mysql You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ''start_date' > '2021-03-03'' at line 1 When I try hard-coding a date in I get the same error. Whats confusing is it works when I directly put it into mysql
