表不存在于数据库中但它确实存在

时间:2022-09-25 23:21:15

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

我正在使用PHP在我的数据库中创建一个动态表并在其中存储一些数据。

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.

有时,当我运行查询时,表创建并执行数据查询,但如果我刷新查询或刷新页面,它会显示错误表示表不存在,如果我刷新页面,它将再次加载数据或3次尝试。

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

我正在动态创建表,然后对它执行操作,最后我正在删除表。这是我的代码

<?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();
        }

      ?>

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

可能是冲突.. 2个并发请求,因此一个请求可以删除另一个请求使用的表尝试将CREATE TABLE更改为CREATE TEMPORARY TABLE

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

为什么要创造和放弃呢?使用CREATE TEMPORARY TABLE或仅在使用后对表进行TRUNCATE
