MySQL错误：1064模棱两可的错误

Question

Well, hello. I have this php script which is the backend process of my DataTables table. Here's the code:

 <?php session_start(); // $username = $_SESSION['username']; if (empty($_SESSION['username'])) { session_destroy(); header('location:login.php'); } /* * Script: DataTables server-side script for PHP and MySQL * Copyright: 2010 - Allan Jardine, 2012 - Chris Wright * License: GPL v2 or BSD (3-point) */ /* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * Easy set variables */ /* Array of database columns which should be read and sent back to DataTables.

I get MySQL Error: 1064 when I try to run the php file, the file didn't gave me JSON response which I needed to display the data to my DataTables.

Can anyone help me with this?

Thank you.

Answer 1

Error 1064 says that your SQL syntax has an error.

Try putting backticks (`) around your table name. I believe MySQL will let you use dashes (-) in a table name, but you have to quote the table name when referring to it or you get an SQL syntax error.

$sQuery = "
    SELECT COUNT(" . $sIndexColumn . ")
    FROM   `$sTable`
";

我认为当您替换“ $ sOrder”时 ，您没有使用别名作为列名
