I have an SQL table with the following columns:

```
title, author, genre, rating

```

On import from SQL to CSV file into HDFS with Sqoop I need to add an extra **non-null** column `src` that has a default value "online" for every input record.
How to do this in Sqoop?
So a resulting record should have the following format:

```
src, title, author, genre, rating

```

where `src` = "online" for every output record
