Question

我收到以下错误：

Fatal error: Uncaught exception 'PDOException' with message 
'SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error 
in your SQL syntax;

但是，我无法解决。行号表示它是15

$res->execute(array_values($params));

你能发现问题吗？

function fetchBgnew(array $conditions){ 
    $db = Core::getInstance();              
    $sql = "SELECT p.id, p.bg, p.bg_desc, p.bg_id, p.user_id, p.panel_id, p.domainurl, 
                   p.type, p.price 
              FROM ".USERS_BG." as p 
              left join ".USERS." as u on p.user_id=u.id WHERE u.status !=0 and 1 and";
    $params = array();
    foreach ($conditions as $column => $value) {
        if (preg_match('/^[a-z]+$/', $column)) {

            $params[] = $value;
            $sql .= "group by p.id desc, LIMIT 0,25";
        }
    }

Answer 1

看起来你忘记了这些空间。

$sql = "SELECT p.id,p.bg,p.bg_desc,p.bg_id,p.user_id, p.panel_id,p.domainurl,p.type,p.price FROM ".USERS_BG." as p left join ".USERS." as u on p.user_id=u.id WHERE u.status !=0 and 1 and";
...
$sql .= "$column = ?";
...
$sql .= "group by p.id desc, LIMIT 0,25";

这将产生类似SELECT ... andcolumn =的声明（注意'和'和'列'之间缺少空格）

此外，您的GROUP BY语法不正确（DESC之后不应该有逗号）并再次丢失空格。想象一下如果你有两个领域会发生什么？

Answer 2

除了@TomvanderWoerdt的（正确...）答案之外：你的sql语句无效，你最后只能添加一个LIMIT子句。

同样适用于GROUP BY条款。
