Question

doubles quotes dont work so you have to type ‘some value’ to actually do variable comparisons when doing direct execution of SQL statements.

Problem is that now when I execute the SQL statement from ASP.NET code I dont seem to be getting any readings…I am not even getting errors :S….

I HAVE tried executing the SQL statement on its own, and it does work.

public static string testExi(string localIncidentNum)
        {

            try
            {
                string query = "SELECT TOP 1 UniqueColID From DBNAME WHERE LocalIncidentNum = @localIncidentNum ORDER BY [version] DESC";

                DataTable dt = new DataTable();
                SqlConnection connection = new SqlConnection(connectionStr);

                SqlCommand command = new SqlCommand(query, connection);
                command.Parameters.AddWithValue("@localIncidentNum", localIncidentNum);

                connection.Open();
                SqlDataAdapter adp = new SqlDataAdapter(command);
                adp.Fill(dt);
                connection.Close();
                command.Dispose();
                connection.Dispose();

                if (dt.Rows.Count != 0)
                {
                    string UniqueColID = dt.Rows[0]["UniqueColID"].ToString();
                    return UniqueColID;
                }
                else
                {
                    return null;
                }


                string some = dt.Rows[0]["UniqueColID"].ToString();
                return some;
            }


            catch (Exception err)
            {
                Global.tmpmsg = " Updating follow up was not successful. " + err.ToString();
                return null;
            }


        }

If I hardcode an incident value in the SELECT statement it works but if I hardcode the incident value in .addwithvalue, it doesn’t work.

    command.Parameters.AddWithValue("@localIncidentNum", "12-023696");

I solved it. The problem was that I (for some reason) needed to put the full path of the table before the table name in sql code when executing it from C sharp file:

SELECT TOP 2 [DB name].[dbo]. [table name]
