I would like to export certain tables of the database to a .sql flat file using SQL Server 2012.
I went to SQL SERVER Management Studio -> Right Clicked on the database I would like to export -> Task -> Export Data
Then I landed on this page

Then I created a filename, Entered " for a Text qualifier
Then I clicked the next button and landed on this screen.

I am unable to continue from here due to the following error:
Columns are not defined for this connection manager.
