How to import data via post deployment script from SQL Server CE into a SQL Server DB freshly created using VS database project - visual-studio-2012

Question

I'm trying to import data from a SQL Server Compact (.sdf) database into a SQL Server database created through Visual Studio database project.
The .sdf database was created by a third party tool from an existant SQL Server database, and it is embedded into the Visual Studio project. The purpose is to deploy the database and insert initial values on a remote machine. I would like to run the import script as a post deployment script something like the following:
INSERT INTO Employer(
EmployerId,
EmployeeName
) SELECT
EmployerId,
EmployeeName
FROM sdfDB.dbo.Employer
Is it possible to reference a SQL Server Compact database (sdfDB)
in T-SQL script?
If not, what is the best practice to import data
into a freshly created DB from an embedded datasource which can be
deployed by build script in a remote machine?

Answer 1

1) Is it possible to reference a SQL Server Compact database (sdfDB) in
T-SQL script?
If you are thinking to something like this,
INSERT INTO [SQL SERVER Db].Table (Values)
SELECT (Values)
FROM [Sql Server Compact Db].Table
unfortunately no, this is not possible.
2) If not, what is the best practice to import data into a freshly
created DB from an embedded datasource which can be deployed by build
script in a remote machine.
You can use the SQL Server Compact Toolbox, that contains features to generate scripts from a Sql server compact file, that you can use to populate the SqlServer database.
Features:
Script!
Migrate a SQL Server Compact database directly to SQL Server (LocalDB/Express)
Migrate from SQL Server Compact to SQL Server, SQL Azure and SQLite via script (...)
