QuestionFacing problem when calling store procedure from c# code Pin
Mou_kol2-Aug-22 7:52
MemberMou_kol2-Aug-22 7:52 
I have store procedure which insert and update data and at the end it return multiple data.
i am using SQL helper utility class to call store procedure. i use

C#
ds = await SqlHelper.ExecuteDatasetAsync(ConnectionManager.GetConnectionString(), CommandType.StoredProcedure, "USP_InsertBMAsLineItem", spParameter);


execution stuck at this line. i am not able to figure out where i made the mistake. when i execute SP from SSMS then everything goes fine. please see my store procedure and c# code. tell me where i made the mistake.

SQL

My C# code which would call SP

C#
public async Task<ResponseContextDto> ConvertToPercentLineItem(string tickerid, string items)
             {
                 DataSet ds = new DataSet();
                 DataTable dt=new DataTable();
                 string userid = GlobalVariable.strLoginID;
                 ResponseContextDto oResponseContext = new ResponseContextDto();
                 string? message = "";
        
                 try
                 {
                     #region db operation start
                     SqlParameter[] spParameter = new SqlParameter[3];
        
                     spParameter[0] = new SqlParameter("@TickerID", SqlDbType.VarChar);
                     spParameter[0].Direction = ParameterDirection.Input;
                     spParameter[0].Value = tickerid;
        
                     spParameter[1] = new SqlParameter("@CommaSeparatedItems", SqlDbType.VarChar);
                     spParameter[1].Direction = ParameterDirection.Input;
                     spParameter[1].Value = items;
        
                     spParameter[2] = new SqlParameter("@UserID", SqlDbType.VarChar);
                     spParameter[2].Direction = ParameterDirection.Input;
                     spParameter[2].Value = userid;
        
                     ds = await SqlHelper.ExecuteDatasetAsync(ConnectionManager.GetConnectionString(), CommandType.StoredProcedure, "USP_InsertBMAsLineItem", spParameter);
        
                     oResponseContext.IsSuccess = Status.Success;
                     oResponseContext.Message = Status.Message(Status.Success);
                     if (ds != null && ds.Tables.Count > 0 && ds.Tables[0].Rows.Count > 0)
                     {
                         dt = ds.Tables[0];
                         oResponseContext.ResponseData = dt;
                     }
                     else
                     {
                         oResponseContext.ResponseData = null;
                     }
        
                     #endregion
                 }
                 catch (Exception ex)
                 {
                     oResponseContext.IsSuccess = Status.Fail;
                     oResponseContext.Message = "Error " + ex.Message;
                     oResponseContext.ResponseData = null;
                 }
        
                 return oResponseContext;
             }


I also tried this way to capture return tabular data from SP into c# datatable but still no luck.

C#
string userid = GlobalVariable.strLoginID;
             ResponseContextDto oResponseContext = new ResponseContextDto();
             DataTable table = new DataTable();
             using (var con = new SqlConnection(ConnectionManager.GetConnectionString()))
             using (var cmd = new SqlCommand("USP_InsertBMAsLineItem", con))
             using (var da = new SqlDataAdapter(cmd))
             {
                 cmd.CommandType = CommandType.StoredProcedure;
                 cmd.Parameters.Add(new SqlParameter("@TickerID", tickerid));
                 cmd.Parameters.Add(new SqlParameter("@CommaSeparatedItems", items));
                 cmd.Parameters.Add(new SqlParameter("@UserID", userid));
                 da.Fill(table);
             }


please guide me what to change in c# code or in SP code.

Thanks
