Delete query takes too long and also does not delete all records
shades posted a topic in MySQL Help
Hi Guys, I have a form where the user can select rows and delete them. But my problem is when I select around 4800 rows to delete it takes too long and also only 2500 rows get deleted. So, could someone help me with the below code so it does not take more time and also deletes all the rows? Note: 1. I use InnoDB 2. I use ajax with async set to false <?php include("dbconnect.php"); ini_set ( 'max_execution_time', 20000); if(isset($_POST['id'])){ foreach ($_POST['id'] as $ids) { $stmt = $dbconnect->prepare("DELETE FROM datatable WHERE id=:id"); $stmt -> bindValue(':id', $ids); $stmt -> execute(); } $data =1; echo $data; } ?> I see in the above code my delete query is executed again and again through the loop and I would like to know if there is a way to execute only one statement and get all the ids inside the statement. Thank you. -
I currently have a php code at the top of the page that would automatically delete a user from the database if a certain condition isn't met before 24 hours. This code is processed no matter where you are on the site. I have two questions. 1. Will this be an issue if the database has thousands of users? 2. Is there a better way to do this?
