[英]How to query using mysqli prepared statements where 2 columns equal different values?
我试图基本上查询数据库，所以它看起来像这样：
$stmt5 = $DBH->prepare("SELECT id FROM numbers WHERE value1 = ? value2 = ?");
$stmt5->bind_param("ss",$value1,$value2);
但是我不断收到“在非对象上调用成员函数bind_param的信息”，我该怎么做？
您错过了AND尝试这个
$DBH->prepare("SELECT id FROM numbers WHERE value1 = ? AND value2 = ?")
