Lianja sql server

Logic to perform a query is self-contained inside the virtual table definition. This gives a clear separation between the UI presentation layer and the underlying data source. Virtual tables are fully updatable with transparent inserts, updates and deletes and they are both SQL and NoSQL compatible. All virtual table connections using the same connection string or DSN are pooled to maximize performance. Virtual tables allow you to join disparate data sources. For example, you can use virtual tables accessing Microsoft SQL Server alongside native Lianja tables, alongside other virtual tables accessing MySQL and build relationships between the data.Creating a Virtual TableIt's always a good idea to test out any ODBC connection you want to use in Lianja in the ODBC Console, so that you can see that the connection is being made and that you can access the tables you expect.I've set up a system DSN called awhr in the Windows 32 bit ODBC Administrator (on 64 bit Windows, this is %windir% \SysWOW64\odbcad32.exe) to connect to the Microsoft SQL Server AdventureWorks sample database on my local machine.In the Lianja App Builder Console Workspace, I enter awhr as the Connstring and once the connection is reported as successful, I list the tables then open the Sales.Currency table to check its structure and data.So, I'm happy that I can connect to the awhr DSN - a DSNless connection string can also be specified in the Connstring field - and that Sales.Currency is the table that I am interested in.

This is an introduction to the use of Virtual Tables. It explains what virtual tables are, their advantages and how to get started using them. Further documentation will give more detailed information on modifying virtual tables, defining their keys, update properties, use of the underlying CursorAdapter object, 'local' virtual tables and more.Contents1 See Also2 What are Virtual Tables?3 What's so special about Virtual Tables?4 Creating a Virtual Table5 Using Virtual TablesSee Also Watch the introduction to the Data Workspace video: Syntax for the CREATE VIRTUALTABLE and ALTER VIRTUALTABLE Commands Properties and Methods of the CursorAdapter Class Virtual Tables - Further Configuration and Troubleshooting Virtual Tables - Local Development, Remote Deployment Virtual Table Properties Virtual Tables - Local Stored Procedures Virtual Tables - Using Parameterized Views SET CONNSTR Command (default 'ODBC Connection') HOWTO integrate Lianja and VFP with concurrent data accessWhat are Virtual Tables?Virtual tables allow you to access external data via an ODBC connection (or an OLEDB connection on Windows), yet they look like regular tables in a Lianja database. You can drag 'n' drop virtual tables in the Page Builder and reference them in the same way as standard tables and all the time the underlying connection, SQL statements and cursor adapter are being handled for you.What's so special about Virtual Tables? Pro TipAll virtual table connections using the same connection string or DSN are pooled to maximize performance. Virtual tables are an all-in-one combination of a connection, SQL commands and a CursorAdapter object, so the connection and the
