MySQL的程序工作在PHP，但不是在asp.net（C＃）

Question

我已經建立了一個MySQL後端使用PHP作爲服務器語言的網站，現在我在asp.net建立同一站點

下面的過程是定義在My​​SQL數據庫：

DELIMITER // 
CREATE PROCEDURE Login(
    IN Username VARCHAR(16), 
    IN UserPassword VARCHAR(16), 
    OUT UID int, 
    OUT SL INT, 
    OUT SP VARCHAR(8), 
    OUT MA BOOL) -- missing admin entry 
BEGIN 
    DECLARE adminID INT DEFAULT -1; 
    DECLARE lastTimeout DATETIME DEFAULT NULL; 
    SET UID = -1; 

    SELECT ID, SecurityLevel, LoginTimeout INTO UID, SL, lastTimeout 
    FROM User 
    WHERE User.UserName = Username and User.Password = UserPassword; 

    IF NOW() > lastTimeout OR lastTimeOut IS NULL THEN 
     IF lastTimeOut IS NOT NULL THEN 
      INSERT INTO UserLog (UserID, Date, Action) VALUES (UID, NOW(), 'TIMEOUT'); 
     END IF; 

     SELECT ID, Password INTO SL, SP 
     FROM SecurityLevels 
     WHERE ID = SL; 

     SELECT UserID INTO adminID 
     FROM Admin 
     WHERE UserID = UID; 

     IF adminID = -1 AND SL = 4 THEN SET MA = TRUE; 
     ELSE SET MA = FALSE; 
     END IF; 

     IF UID != -1 THEN 
      INSERT INTO UserLog (UserID, Date, Action) VALUES (UID, NOW(), 'LOGIN'); 
      UPDATE User SET User.LoginTimeOut = DATE_ADD(NOW(), INTERVAL 1 HOUR) WHERE User.ID = UID; 
     END IF; 
    ELSE 
     SET UID = -1; 
    END IF; 

END // 
DELIMITER ; 

我使用的用戶是：

CREATE USER 'LOGIN'@'%' IDENTIFIED BY '6Jd8kKi0'; 
GRANT execute ON procedure b09xxxxx.Login TO 'LOGIN'@'%'; 

現在，在PHP我不喜歡這樣，它就像一個魅力：

$pdo = new PDO('mysql:dbname=b09xxxxx;host=wwwlab.xxx.xxx.se', 'LOGIN', '6Jd8kKi0'); 
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING); 

$userID = 0; 
$securityLevel = 0; 
$securityPassword = ""; 

//$sql = "SELECT UserName, ID, SecurityLevel FROM User WHERE UserName = '" . $_POST['username'] . "' and Password = '" . $_POST['password'] . "';"; 
$sql = "CALL Login(:USERNAME, :PASSWORD, @UID, @SL, @SP, @MA);"; 

$stmt = $pdo->prepare($sql); 
$stmt->bindParam(':USERNAME', $_POST['username']); 
$stmt->bindParam(':PASSWORD', $_POST['password']); 
$stmt->execute(); 

//$q  = $pdo->query($sql) or die("ERROR:DB"); 

$sql = "SELECT @UID, @SL, @SP, @MA;"; 

$q = $pdo->query($sql) or die("ERROR:DB"); 

$r = $q->fetch(PDO::FETCH_ASSOC); 

但這asp.net（C＃）版本不工作：

string connectionString = "Server=wwwlab.xxx.xxx.se; Database=b09xxxxx; User ID=LOGIN; Password=6Jd8kKi0; Pooling=false;"; 
MySqlConnection dbcon = new MySqlConnection(connectionString); 
dbcon.Open(); 

//string query = "CALL Login(:USERNAME, :PASSWORD, @UID, @SL, @SP, @MA);"; 
//Now changed to this thanks to John Woo 
string query = "Login"; 

MySqlCommand sqlCmd = new MySqlCommand(query, dbcon); 
sqlCmd.CommandType = System.Data.CommandType.StoredProcedure; 

sqlCmd.Parameters.AddWithValue(":USERNAME", loginUsername.Text); 
sqlCmd.Parameters[":USERNAME"].Direction = ParameterDirection.Input; 
sqlCmd.Parameters.AddWithValue(":PASSWORD", loginPassword.Text); 
sqlCmd.Parameters[":PASSWORD"].Direction = ParameterDirection.Input; 

sqlCmd.Parameters.Add(new MySqlParameter("@UID", MySqlDbType.Int64)); 
sqlCmd.Parameters["@UID"].Direction = ParameterDirection.Output; 
sqlCmd.Parameters.Add(new MySqlParameter("@SL", MySqlDbType.Int64)); 
sqlCmd.Parameters["@SL"].Direction = ParameterDirection.Output; 
sqlCmd.Parameters.Add(new MySqlParameter("@SP", MySqlDbType.String)); 
sqlCmd.Parameters["@SP"].Direction = ParameterDirection.Output; 
sqlCmd.Parameters.Add(new MySqlParameter("@MA", MySqlDbType.Byte)); 
sqlCmd.Parameters["@MA"].Direction = ParameterDirection.Output; 

sqlCmd.ExecuteNonQuery(); 

MySqlDataAdapter adapter = new MySqlDataAdapter("SELECT @UID, @SL, @SP, @MA;", dbcon); 
DataSet ds = new DataSet(); 
adapter.Fill(ds, "result"); 

CustomerGrid.DataSource = ds.Tables["result"]; 
CustomerGrid.DataBind();    

dbcon.Close();http://stackoverflow.com/editing-help 

我收到以下錯誤：

過程或函數 'CALL Login(:USERNAME, :PASSWORD, @UID, @SL, @SP, @MA)' 不能在數據庫 'b09xxxxx' 中找到。

編輯：現在這是新的問題：SELECT命令拒絕用戶LOGIN'@'193.11.99.23'表「PROC」

我估計調用方法.fill僞時產生錯誤。

更改下面的代碼;

MySqlDataAdapter adapter = new MySqlDataAdapter("SELECT @UID, @SL, @SP, @MA;", dbcon); 
DataSet ds = new DataSet(); 
adapter.Fill(ds, "result"); 
CustomerGrid.DataSource = ds.Tables["result"]; 

With;

DataTable table = new DataTable(); 
table.Columns.Add("UID", typeof(int)); 
table.Columns.Add("SL", typeof(int)); 
table.Columns.Add("SP", typeof(string)); 
table.Columns.Add("MA", typeof(boolean)); 

table.Rows.Add(sqlCmd.Parameters["@UID"].Value, sqlCmd.Parameters["@SL"].Value, sqlCmd.Parameters["@SP"].Value, sqlCmd.Parameters["@MA"].Value); 
CustomerGrid.DataSource = table
