存储过程执行没有问题,@o_userid在ems sqlmanage下测试也有值,但是在php下边调用就会报错,请高手指点一下?

$sql = "CALL UserCheck(@o_userid,'".$userName."','".$usrPass."');";
$conn = db_connect();
if($result = mysqli_query($conn,$sql) or die(mysqli_error()))
{
$rs = mysqli_query($conn,"select @o_userid")  or die(mysqli_error()); //这一句报错?
$row = $rs->fetch_array();
Warning: mysqli_error() expects exactly 1 parameter, 0 given in E:\biyie\htdocs\pilin\data\loginusermiddle.php on line 19
$row = $rs->fetch_array();

解决方案

mysqli_error()需要参数。。。

mysqli_error($conn)
