我收到错误
过程或函数“myStoreProcNameHere”指定了太多参数。
以下是我的存储过程和SqlDataSource
。我正在使用GridView编辑数据。
帮助? :(
存储过程:
ALTER PROCEDURE UpdateTwoTables

@UserID varchar(10),
@Pass varchar(50),
@Enabled int,
@Permission int,
@Rank int,
@FName varchar(50),
@LName varchar(50),
@Phone varchar(50),
@Email1 varchar(50),
@Email2 varchar(50)
)
AS
BEGIN TRANSACTION
UPDATE tbl_user_login
SET UserID = @UserID, Pass = @Pass,
Enabled = @Enabled, Permission = @Permission,
Rank = @Rank
WHERE ID = @ID
IF @@ERROR <> 0

RETURN
END
UPDATE tbl_user_profile
SET FName = @FName, LName = @LName,
Phone = @Phone, Email1 = @Email1, Email2 = @Email2
WHERE ID = @ID
IF @@ERROR <> 0

在我从循环(foreach)中调用存储过程之前,我遇到过此错误消息。
我收到的异常原因是由于我在循环的每次迭代后都没有清除参数。
例如: 这段代码抛出:
using (SqlCommand cmd = new SqlCommand())
{
cmd.CommandType = System.Data.CommandType.StoredProcedure;
cmd.CommandText = "MySproc";
foreach (MyClass c in myClasses)
{
cmd.Parameters.AddWithValue("@val1", c.val1);
cmd.Parameters.AddWithValue("@val2", c.val2);
var result = MyDbManager.instance.ExecuteScalarQuery(cmd);
}
}
修复方法是清除参数:
using (SqlCommand cmd = new SqlCommand())
{
cmd.CommandType = System.Data.CommandType.StoredProcedure;
cmd.CommandText = "MySproc";
foreach (MyClass c in myClasses)
{
cmd.Parameters.AddWithValue("@val1", c.val1);
cmd.Parameters.AddWithValue("@val2", c.val2);
var result = MyDbManager.instance.ExecuteScalarQuery(cmd);
cmd.Parameters.Clear();
}
}

实例必须创建
Vb.Net&amp; C#
glopal值
vb.net -> Dim cmd as New SqlCommand()
c#-> Sqlcommand cmd=new sqlCommand()
Con.open()
cmd=New SqlCommand()
something write...
Con.Close()
