How can I export my 2012 database with data to a .sql file so I can import it to a 2008 server? I've never been able to export the data only the structure.
You can right click on the database in management studio. then go to,
Tasks --> Generate scripts --> Advanced
There you can enable "Type of data to script" as Schema and data
, then generate the script. So that your script file will be populated with your data in table.
