過程或函數預計參數「@OperatorName」，但未提供

Question

我得到一些意外的錯誤， 我有兩個兩種方法之一是的insertUpdate &另一個GETDATA

for INSERT UPDATE SP is -- >> spInsert_WorkEntry 
for GETDATA SP is  -- >> spGetWorkEntryData 

兩者的SP參數與圖像中顯示的相同。

我正在動態生成參數。如CreateParams所示。 創建參數對於INSERTUPDATE & GETDATA的兩種方法都是相同的。

插入更新方法正常工作&按預期工作。

但是，當我試圖執行另一種方法，即GETDATA它給我錯誤@OperatorName參數預計。 第一個參數是@AutoID該參數沒有給出錯誤。 我檢查了所有可能會導致問題的可能情況，但現在可以獲得任何信息。

public int InsertOrUpdate(WorkEntry t, string callingPage, string operation) 
{ // Start the Insert Update Method 
    IDbDataParameter[] param = null; 
    int returnValue = 0; 
    try

     param = CreateParams(t, callingPage, operation); 
     param[0].Value = t.AutoID; 
     param[1].Value = t.OperatorName;

     command.CommandText = "spInsert_WorkEntry"; 
     command.Parameters.AddRange(param); 

     returnValue = command.ExecuteNonQuery(); 
     sqlConnection.Close();

下面是SP的圖像

Answer 1

嘗試前SqlDataAdapter da = new SqlDataAdapter(command);聲明

SqlConnection sqlConnection = new SqlConnection(ConfigurationManager.AppSettings["ConnectionString"].ToString()); 
     sqlConnection.Open(); 
     SqlCommand command = sqlConnection.CreateCommand(); 
    command.Parameters.AddRange(param); 
     SqlDataAdapter da = new SqlDataAdapter(command); 
     command.CommandType = System.Data.CommandType.StoredProcedure; 
     command.CommandText = "spGetWorkEntryData"; 

     da.Fill(ds); 

也爲select語句移動command.Parameters.AddRange(param);，如果你不使用Where條款，那麼也許傳遞參數是不必要的。

更新：我測試了它和它在我的例子做工精細

我到你Get方法

public DataSet Get(string callingPage, string operation) 
    { // Start the Insert Update Method 

     // new instance of dataset and sqlcommand 
     DataSet ds = new DataSet(); 
     SqlCommand command = new SqlCommand(); 

     IDbDataParameter[] param = null; 
     DataSet returnValue = new DataSet(); 
     try 
     { 
      param = CreateParams(callingPage, operation); 
      param[0].Value = 1; 
      param[1].Value = ""; 
      param[2].Value = DateTime.Now; 
      param[3].Value = DateTime.Now; 
      param[4].Value = DateTime.Now; 

      // using connectin string property insted ConfigurationManager.AppSettings 
      SqlConnection sqlConnection = new SqlConnection(ConfigurationManager.ConnectionStrings["Connection"].ConnectionString); 
      sqlConnection.Open(); 
      command = sqlConnection.CreateCommand(); 
      SqlDataAdapter da = new SqlDataAdapter(command); 
      command.CommandType = System.Data.CommandType.StoredProcedure; 
      command.CommandText = "spGetWorkEntryData"; 
      command.Parameters.AddRange(param); 
      da.Fill(ds); 

      sqlConnection.Close(); 
      return returnValue; 

     } 
     catch (Exception ex) 
     { 
      throw ex; 
     } 
     finally 
     { 
      param = null; 
      command.Parameters.Clear(); 

     } 
    }// End 

我演示存儲過程

Create proc [dbo].[spGetWorkEntryData] 
@autoId int, 
@operatorName varchar(100), 
@date datetime, 
@startDate datetime, 
@enddate datetime 

as 

begin 
select * from dbo.tblBinaryUsers 
end 

做了一些改動結果：

Answer 2

取下選擇查詢SP spGetWorkEntryData所有參數，它並不需要這個， 和你的SP將是

create proc spGetWorkEntryData 
as 
begin 
select operatorname, date, startdate ,enddate from workentry 
end
