Datasources

(datasources)

Overview

Datasources in Servoy provide a structured way to interact with various types of data sources, such as database tables, in-memory tables, views, and stored procedures. These datasources are accessible through the datasources object and support dynamic code completion based on the solution’s data model, enabling efficient development.

Datasources include types like DBDataSource, MemDataSource, ViewDataSource, SPDataSource, and MenuDataSource, each catering to a specific use case. For example, db is used for server/table-based data sources, mem for in-memory tables, and view for view foundset data sources. Stored procedures are managed under the sp property, with server-side configuration enabling their use. The menu property handles menu-related datasources.

For details related to datasources, refer to the specific sections in the Servoy documentation:
