Purpose

Use Connect SQL rules when your application needs to run complex Structured Query Language statements such as joins or stored procedures to update or extract information from an external database.

Alternative: If your application needs to perform a simple browse, open, delete, or update operation against an external database, use the Connector and Metadata Accelerator to configure external table access. When external table access is configured for an external table, you can use the Obj-Open, Obj-Browse, and other Obj- methods to interact with that table through a class that represents it and you do not need to create SQL connector rules. See About generating connector rules.

Access

Use the Application Explorer or the Integration slice () to see Connect SQL rules in your application. Use the Rules by Type Explorer to list all the Connect SQL rules that are available to you.

Development

To configure an SQL connection to an external database, use the following elements along with the Connect-SQL rule:

• An activity that references one or more of four standard methods for operating on relational databases — RDB-Open, RDB-List, RDB-Delete, and RDB-Save. The names of the methods match the names of the tabs in the connector rule. An activity that uses RDB-Open to call a connector rule runs the SQL statement on that connectors Open tab, and so on.
• A Database instance and one or more Database Table instances that provide access to the tables or views of the external database.
• A JDBC library that provides access to the external database software.
• Special data mapping syntax to associate properties with database columns.
