The DB-to-XML Data Source Editor

You use the DB-to-XML data source editor to specify database connectivity settings, and to compose the SQL/XML (queries and other actions) that you want to execute on the server.

Figure 274. DB-to-XML Data Source Editor

SQL/XML Editor

The SQL/XML editor is on the left side of the DB-to-XML data source editor. It consists of two tabs, SELECT and UPDATE, which you use to compose SQL/XML SELECT and, optionally, UPDATE and INSERT statements. You can type directly in the editor, or you can use drag-and-drop to automatically compose SQL/XML statements.

See Composing SQL/XML in Stylus Studio to learn more about using the SQL/XML editor.

Database Schema Tree

The database schema tree is on the right side of the DB-to-XML data source editor. Once you have established a connection to the database specified in the scenario, Stylus Studio displays a tree diagram of the database schema.

Figure 275. Database Schema Tree

The database schema tree is displayed by default. You can hide it by clicking the Show/Hide Database Schema button ( ).

Information in the schema tree is displayed in a hierarchical fashion, starting with the server you specified in the scenario. Tables, views, and columns are displayed in database order; column data types are displayed in the Type column.

Working with Relational Data

Stylus Studio can automatically create valid SELECT, INSERT, and UPDATE SQL/XML statements based on the objects you select from the database schema tree. In addition, your DB-to-XML data source can contain any valid SQL/XML statement defined on the SELECT or UPDATE tabs. The actions that can be performed by the SQL/XML you define in your DB-to-XML data source are limited only by the permissions of the username you use to log in to the database. See Composing SQL/XML in Stylus Studio for more information on this topic.
