表不存在于数据库中但它确实存在

Question

I'm using PHP to create a dynamic table in my database and store some data in it.

Sometimes when i run the query the table is created and data query is executed but then again if i refresh the query or refresh my page, it shows Error saying table doesn't exist and again if i refresh my page it will load data in 2 or 3 tries.

I'm creating table dynamically and then perform operation on it and at the end I'm dropping the table. Here is my code

<?php

$droptable = "DROP TABLE IF EXISTS temp_post";

if(!mysql_query($droptable))
{echo msql_error();}

    $sqlcreatetable = "CREATE TABLE temp_post(
    id INT NOT NULL AUTO_INCREMENT PRIMARY KEY,
    seq_id INT (6),
    name VARCHAR(64) NOT NULL)";

    if(!mysql_query($sqlcreatetable))
        {
            echo " ERROR CREATING TABLE --> ".mysql_error();
        }
    else{
           //query here
        }
        $sqldel = "DROP TABLE temp_post";
        if(!mysql_query($sqldel)){
            echo "ERROR DELETING TABLE --> ".mysql_error();
        }

      ?>

I've gone through some other posts and tried the solutions but still its not working properly.Help!!.. CHEERS

Answer 1

May be conflicts.. 2 simultaneous requests, so one request can drop table that is used by another request
Try to change CREATE TABLE to CREATE TEMPORARY TABLE

Answer 2

Why create and drop anyway? Use CREATE TEMPORARY TABLE or just TRUNCATE the table after use
