Define Hive Macros

You can use the Hive Macro Editor to define a set of statements that are frequently used or that perform a complex operation in a Hive physical model.

Note: Macros in Hive do not support Reverse Engineering from Database (REDB). Also, by default, the admin role is not in the current roles. While generating a macro, on the Forward Engineer Schema Generation dialog box, under Other Options, ensure that you select Set Admin Role.

To define a Hive macro

1. In the Model Explorer, right-click Macros and click New.

   An instance of a Macro is created.

2. Right-click the instance and click Properties.

   The Hive Macro Editor opens.

   Note: Click New on the toolbar to create a new macro. Use the Enter filter text text box to filter a very large list of macros to quickly locate the one you want to work with.

   Name

3. Click the Parameters tab and work with the following options. Click New on the toolbar to create a new parameter.

5. Work with the other tabs in the editor to access additional design features, for example:
   • View the fully expanded macro code on the Expanded tab.
