I am noticing major load time in retrieving results from large tables
imgrooot posted a topic in PHP Coding Help
I am retrieving data from multiple joined tables that contain around 3,500 rows each. I am only showing limited results but the load time is the same. Like it takes 5 seconds to load the page. I don't want this same issue to continue if I am predicting over 1,000,000 rows from these tables. So what's the best way to fix this? Here is my query. $get_members = $db->prepare("SELECT users.*, approvals.*, sponsors.* FROM approvals LEFT JOIN users ON approvals.user_id = users.user_id LEFT JOIN sponsors ON approvals.user_id = sponsors.sponsored_user WHERE user_id > :user_id ORDER BY user_id DESC LIMIT 20"); $get_members->bindValue(':user_id', 0); $get_members->execute(); $result_members = $get_members->fetchAll(PDO::FETCH_ASSOC); if(count($result_members) > 0) { foreach($result_members as $row) { // show results here } } else { echo 'none'; } if(count($result_members) < 20) {} else { // show-more button here }
