MySQL查询执行错误

Question

我无法执行SQL查询，如下所示;

"Could not execute SQL query" SELECT * FROM tbl_fault WHERE id>0 AND `release`='2.70.000.04'

原因可能是，我正在使用mysql_real_escape_string，如下所示

if ($_REQUEST["releasenu"]<>'') {
$search_releasenu = " AND `release`='".mysql_real_escape_string($_REQUEST["releasenu"])."'"; }

mysql数据库中的release列是VARCHAR

需要建议！

亲切的问候

Answer 1

改变你的代码

$search_releasenu = " AND `release`='".mysql_real_escape_string($_REQUEST["releasenu"])."'"; }

至

$search_releasenu = " AND release='".mysql_real_escape_string($_REQUEST["releasenu"])."'"; }

如上所述，从释放中删除aprostrophe

Answer 2

尝试这个：

if ($_REQUEST["releasenu"]<>'') {
$search_releasenu = " AND release='".mysql_real_escape_string($_REQUEST['releasenu'])."'"; }
