  DAAB how to get multiple output parameters ?

  May 09, 2011 08:10 AM|LINK

  A stored procedure is returning 2 output parameter. I tried to catch them in DAL using DAAB but couldn't succeed. Actually control did not returned on next lines. Please guide me.

   

  using (DbCommand dbCommand = db.GetSqlStringCommand("p_AddLeaveApplication"))
              {
                  dbCommand.CommandType = CommandType.StoredProcedure;
                  db.AddInParameter(dbCommand, "@EmployeeId", DbType.Int16, leave.EmployeeId);
                  db.AddInParameter(dbCommand, "@DateTo", DbType.Date,string.Format("'{0:yyyy-MM-dd HH:mm:ss}'",  leave.DateTo));
                  db.AddInParameter(dbCommand, "@DateFrom", DbType.Date, string.Format("'{0:yyyy-MM-dd HH:mm:ss}'", leave.DateFrom));
                  db.AddInParameter(dbCommand, "@LeaveType", DbType.String, leave.LeaveType);
                  db.AddOutParameter(dbCommand, "@Result", DbType.Int16, 1);
                  db.AddOutParameter(dbCommand, "@LeaveId", DbType.Int16, 1);
                  db.ExecuteNonQuery(dbCommand);
                  LeaveId = Convert.ToInt16(db.GetParameterValue(dbCommand, "@LeaveId"));
                  return result = Convert.ToInt16(db.GetParameterValue(dbCommand, "@Result"));
              }

  Thanks in anticipation,

  If you are creating a DbCommand, you can use that to get the output params:

  db.GetParameterValue(dbCommand, "@LeaveID")

  Thanks DarrellNorton,

   

  Please guide me one more thing.

  It is when I need to catch 2 output parameters should I do like:

  db.GetParameterValue(dbCommand, "@LeaveID");
  
  db.GetParameterValue(dbCommand, "@UserId");
  
  also will it call stored procedure two times ? or for gettign all output paramters it will just call sp once ?
  
  
  

  Thanks in anticipation,

  Hi Haansi,

  Haansi

  It is when I need to catch 2 output parameters should I do like:

  It won't execute your procedure when you call these lines.

  db.GetParameterValue(dbCommand, "@LeaveID");

  
  db.GetParameterValue(dbCommand, "@UserId");
  

  Actually, it is called when you call db.ExecuteNonQuery(dbCommand); After this, all the output parameters are retrieved from the your procedure.  You can see the steps from this link.   http://msdn.microsoft.com/en-us/library/system.data.common.dbcommand.aspx

  Best regards,

  Jonathan
