Asp.net Sql 参数丢失

Question

我正在尝试调用带有多个参数的存储过程，但收到错误

“过程或函数‘sp_User_Create’需要参数 '@adminUser'，未提供。"

当我发送一个 0 值时

但是当我使用大于 0 的值调用存储过程时，它可以正常工作吗？

这是我的代码....

SqlConnection con;
SqlCommand cmd = new SqlCommand();
con = new SqlConnection("server=XXX.XXX.XXX.XXX; database=xxxxxxx; uid=xxxxxxx; pwd=xxxxx");
cmd = new SqlCommand("sp_User_Create", con);
cmd.CommandType = CommandType.StoredProcedure;

cmd.Parameters.Add(new SqlParameter("fullName", txtFirstName.Text + " " + txtLastName.Text));
cmd.Parameters.Add(new SqlParameter("emailAddress", txtEmailAddress.Text));
cmd.Parameters.Add(new SqlParameter("password", txtPassword.Text));
cmd.Parameters.Add(new SqlParameter("phoneNumber", txtPhoneNumber.Text));
cmd.Parameters.Add(new SqlParameter("jobTitle", txtJobTitle.Text));
cmd.Parameters.Add(new SqlParameter("createDate", DateTime.Now));
cmd.Parameters.Add(new SqlParameter("companyId", 116));
cmd.Parameters.Add(new SqlParameter("adminUser", 0));
cmd.Parameters.Add(new SqlParameter("userExpireDate", DateTime.Now.AddDays(7)));
cmd.Parameters.Add(new SqlParameter("userAccessLeaderboardClips", 99));
cmd.Parameters.Add(new SqlParameter("userAccessLeaderboardUsers", 99));
cmd.Parameters.Add(new SqlParameter("userAccessLeaderboardVideos", 99));
cmd.Parameters.Add(new SqlParameter("userAccessShared", 99));
cmd.Parameters.Add(new SqlParameter("userAccessEmbed", 99));
cmd.Parameters.Add(new SqlParameter("userAccessTinyUrl", 1));
cmd.Parameters.Add(new SqlParameter("userAccessAllowCreatedVideos", 1));
cmd.Parameters.Add(new SqlParameter("userAccessDownload", 99));
cmd.Parameters.Add(new SqlParameter("companyName", "My Company Name"));
cmd.Parameters.Add(new SqlParameter("logoName", "the logo name"));
cmd.Parameters.Add(new SqlParameter("postcode", "XXXX XXX"));
cmd.Parameters.Add(new SqlParameter("optIn", true));
cmd.Parameters.Add(new SqlParameter("accountType", ""));
cmd.Parameters.Add(new SqlParameter("transactionDesc", ""));
cmd.Parameters.Add(new SqlParameter("transactionDate", ""));
cmd.Parameters.Add(new SqlParameter("transactionAmount", ""));

con.Open();
cmd.ExecuteNonQuery();
con.Close();

我已经检查了存储过程并且它正在等待：

@adminUser as int

这是存储过程：

INSERT INTO UserTransactions(UserID, TransactionDesc, TransactionDate, TransactionAmount, AccountType, ResellerParameter, CampaignParameter)

我只是不明白为什么当发送一个零时它说参数丢失，但是当我发送大于零的东西时它工作得很好？

Answer 1

使用 SqlParameter 构造函数的此重载来指定整数参数值时要小心。由于此重载采用 Object 类型的值，因此必须在值为零时将整数值转换为 Object 类型。

如果您不执行此转换，编译器会假定您正在尝试调用 SqlParameter (string, SqlDbType) 构造函数重载。-MSDN

试试这个

cmd.Parameters.Add(new SqlParameter("@adminUser", SqlDbType.Int).Value=0);

Answer 2

您需要在传递给过程的所有参数的参数名称之前添加“@”

cmd.Parameters.Add(new SqlParameter("@adminUser", 0));

Answer 3

宾果游戏！ - 修复它。

我已将代码更改为：

cmd.Parameters.AddWithValue("@adminUser", 0);

感谢您的关注和帮助！

Answer 4

您需要在每个参数名称之前添加 @ 符号，就像您添加的一样
cmd.Parameters.AddWithValue("@adminUser", 0); for cmd.Parameters.Add(new SqlParameter("adminUser", 0));
