The attached pdf-format documents provide information about:

Installing Microsoft SQL Express 2012
Using the Microsoft SQL Server Management Studio
Using the APLNext Database Interface Tools for SQL Server

Microsoft SQL Express 2012 is a free version of Microsoft SQL Server 2012 which has the full functionality of the commercial versions, a relatively large data limit of 6Gb and can be distributedd royalty-free. The attached document provides detailed instructions for installing this software.

The Microsoft SQL Server Management Studio is an application to create and manage Microsoft SQL databases. It is included in the installation of Microsoft SQL Express 2012. The attached document provides detailed instructions to use this software to create databases, including a sample database.

The APLNext Database Interface Tools for SQL Server is an interface between APL+Win and Microsoft SQL Server using methods which support the Transact SQL (structured query language) used by Microsoft SQL Server. The attached document provides detailed instructions to use this software with a sample database.

Is it possible to connect to localdb with the APLNext Database Interface Tools for SQL Server? If so, how you do that?

The attached document "Use Microsoft SQL Server Management Studio to Connect to LocalDB.pdf" describes how to use Microsoft SQL Server Mangement Studio to connect to and manage the 'localdb' SQL Server which can be installed with Microsoft SQL Express 2012.

The attached document indicates why the current (as of 05/09/2012) version of the APLNext Database Interface Tools for SQL Server cannot access the 'localdb' instance of the Microsoft SQL Express 2012 database software.

A future version of the APLNext Database Interface Tools for SQL Server may resolve this Microsoft limitation.

This link http://forum.apl2000.com/viewtopic.php?f=21&t=849#p3329 asks Is it possible to connect to localdb with the APLNext Database Interface Tools for SQL Server? This link http://forum.apl2000.com/viewtopic.php?f=21&t=849#p3331 suggests that there may be a problem.

In my experience, it is possible to use LocalDB with the APLNext Data Interface Tool - see the attached PDF for a workaround. Here's my session:

Note the Data Source specificaion on line [3] in the function listed above.

Of course you can use ADO with an ODBC driver or an OLEDB provider and, if MSSQLLocalDB is started, simply use LocalDB\MSSQLLocalDB as the server.
