Creating a Database Operation

Set up a database operation to extract data from a relational database. A data service—and the view model on which it is based—can use database operations as input sources.


Before you configure a database operation, make sure that a database connector has been created for the appropriate database. A database operation relies on its database connector to connect to the relational database from which the database operation extracts data.

  1. To connect to the grid domain controller (GDC) for the Data Federation domain where you’ll create your database operation, right-click the GDC in Enterprise Explorer, then click Connect. The data catalog for the GDC’s domain appears beneath the GDC in Enterprise Explorer.
  2. To locate your database connectors in Enterprise Explorer, expand Categories > ViewLibrary > DatabaseServices. DatabaseServices contains a folder for each database connector; the folder contains the database connector itself and its database operations.
  3. (Optional) If you’re not sure which database connector you want, right-click on any of the items in the folders in DatabaseServices and select Get Info. WorkSpace Data Federation displays a summary description of the item.
  4. Right-click on a database connector’s folder and select Database Operation. WorkSpace Data Federation launches the database operation wizard.
  5. Complete the following information on the wizard pages:
    Table 1. Database connector selection page
    Field Description
    Domain Select the Data Federation domain where you want the database operation to be created.
    Database connector Select a database connector for your new database operation to use.
    Table 2. Name and Description page
    Field Description
    Name Enter a name for this database operation.
    Description (Optional) Enter some descriptive information about this database operation.
    Table 3. Basic Operation Properties page
    Field Description
    SQL Statement Enter the query that this database operation will execute. For example:
    • select * from dept
    • select * from emp where ENAME = ?
    Modifies Database Click Yes if this database operation performs an update, insert, or other operation that writes to the back-end database.
    Caching Choose the caching behavior for the results of this database operation.
    Run as Specify which Data Federation user the database operation will be run as. To run the database operation as the current user, click The user running the operation.

    To run the database operation as the same user every time, regardless of which user or application calls it, click A specific user and enter a qualified user ID. Use this format:


    For example:


    Alternatively, click Browse to select a user.

    Calls a stored procedure Select this option if the SQL statement involves a stored procedure in the underlying database.
    Supports batch operations Select this option if the statement is an update that can be used with JDBC batch mode.
  6. If your SQL statement requires any parameters, specify a data type for each parameter on the Parameter Types page, then click Next.
  7. If your SQL statement requires any parameters, specify a value for each parameter on the Parameter Values page, then click Next. WorkSpace only uses these values when it executes the database operation to generate the schema. You will be able to supply different values at runtime.
  8. Click Finish. WorkSpace Data Federation creates the new database operation and executes it to generate its schema. (The schema is needed when the database operation is used to generate a SQL view or as an input source for a view model.)
