I am new to C# and never worked with it before, but for some reason I must chose it for my SQL 2012 SSIS script task. I need to retrieve data from SQL Server database. But using Reader: reader = cmd.ExecuteReader(); my script throws an exception when Reader gets NULL value, e.g reader.GetString(x). Is there any better way to retrieve the data? And another question I am trying to assign the data to the String variable but it produce an extension. I declared it as String sStr; and using sStr = reader.GetString(x). What do I do wrong?
