  • How to speed up mysql query?
  • Remove the non-standard abbreviation sec
  • I have a website about vacation villa rentals. Around 800 properties are listed. When i start a search, i get properties with my first query which filters type, style, area, no. of rooms, capacity etc. After i get the list, a foreach loop shows the results. If check-in and check-out dates are not selected, 800 properties take 1 sec max in mysql query.
  • But if dates are selected, inside the loop, i make another mysql query to get prices of the propery between selected dates from a table called property_prices. (if no price exists, or the condition of the propery is not "booked" for a or any day in the selected range)
  • Below is the first query which takes 1 second the return 800 property details.
  • `$sql = "SELECT property_id, property_capacity, property_rooms FROM properties WHERE property_status = 2 ";`
  • And this one is for the prices is check-in and check-out dates are given.
  • `$res = $Db->row("SELECT SUM(price_value) AS TotalPrice, COUNT(price_id) AS TotalRecord FROM property_prices WHERE price_property_id = ? AND price_date BETWEEN '$sdate' AND '$edate' AND ((price_date = '$sdate' AND price_condition IS NOT NULL) OR (price_date > '$sdate' AND price_condition = ?)); ", array($listing['property_id'],1));`
  • The problem starts here, i get the results in 30 seconds when i search for the total price for each property. I'm happy to make pagination but* i have a sorting filter for customer to sort from cheap to expensive or reverse.
  • As i don't know the total prices for each property, i can not sort the list if i make a pagination.
  • The property_price table has
  • `| id | propery_id | date | price | condition
  • `
  • Any ideas/offers, how i can manage to speed up the query?
  • As the property prices change alot, i cannot use memcache for search result.
  • Cheers
