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?

Hi Burzhuin;

The GetString method must return a non null value so you will need to test if it has a value first like in the following code snippet.

// Initialize the variable to an empty string
string sStr = "";
// Get the Field/Column only if not null 
if ( !reader.IsDBNull(x) )
   sStr = reader.GetString(x);

Open in new window


Not sure what you mean by this, "And another question I am trying to assign the data to the String variable but it produce an extension.", can you explain in a little more detail.
