Define Oracle View Column Properties

In a model based on the Oracle target server, you use the General tab in the View Column Editor to manage the domain parent, physical data type, and other properties for the selected column.

To define Oracle view column properties

1. Right-click a view column in the Model Explorer and click Properties.

   The Oracle View Column Editor opens.

2. Select the view from the View drop-down that contains the column that you want to define.
3. Select the column in the Navigation Grid that you want to define.

   Note: Click New on the toolbar to create a new column. Use the Enter filter text box to filter a very large list of columns to quickly locate the one that you want to define.

4. Click the General tab and work with the following options:

   Domain Parent

   Displays the current parent domain. You can change the domain using the check boxes. Use the toolbar to sort the domain list or open the Domain Editor to work with domains.

   Name

   Displays the view column name. You can change the name in this field or specify one of the following naming options:

   Inherit

   Specifies to inherit the view column name from the domain.

   Override

   Specifies to override inheritance of the view column name.

   Harden

   Specifies to harden the view column name.

   Physical Data Type

   Lets you select a data type from the drop-down list to apply to the selected column. If the selected data type requires a value for precision, scale, or both, enter the value inside the data type parentheses. For example, you can select the DECIMAL() data type and specify a precision of 2 and a scale of 10 inside the parentheses to assign the data type DECIMAL(2,10) to the selected column.

5. Click the Expression tab and enter a view column expression, which is a user-defined expression that is stored as a view column.
6. Click the Indexes tab to manage index membership.
7. (Optional) Click the Style tab to manage themes and display options for the view column.

10. (Optional) Click the UDP tab to work with user-defined properties for the view column.
11. (Optional) Click the Notes tab to view history information and view or edit user notes.
