How to Create a DB-to-XML Data Source

To create a DB-to-XML data source:
1. Select File > New > DB to XML Data Source from the menu.

Stylus Studio displays the Scenario Properties dialog box.

2. Specify a scenario name (or accept the default).
3. Specify the information needed to connect to the database server and log in to the database. This information includes
    • The database type (Oracle or Sybase, for example)
    • The server on which the database resides
    • The username, password, and any other information required to log in to the database.

See Specifying Connection Settings if you need help with this step. If you selected DataDirect SequeLink for the database type, see Using DataDirect SequeLink as a DB-to-XML Data Source.

Alternative: If you have already defined a default connection setting and you want to use it for this scenario, click the Use Default Connection field.

4. Click OK to save the scenario.

Stylus Studio automatically connects to the database and logs you into the server. The database schema, table, view, and column information for the database you specified in the scenario appears in the schema pane of the DB-to-XML Data Source Editor.

5. Compose the SQL/XML SELECT statement to query the database. (UPDATE and INSERT statements, which write modified data back to the database, are optional.) See Composing SQL/XML in Stylus Studio.
6. Click the Execute Query button ( ) the query and review the XML it returns.
7. Optionally (if you have written SQL/XML to write new or modified data to the database), save the XML document returned by the SQL/XML query to write data back to the database. See Working with Relational Data as XML.

The remainder of this chapter describes these steps in greater detail.
