Synonym Editor Layout

The Field View tab shows a hierarchy of segments and columns on the left, with the attributes and values of the selected item on the right.

Note: The attributes available depend on the type of synonym.

The image below is an example of an SQL data source with a key column selected.

Note: Information about the attribute that has focus is displayed at the bottom of the attribute list. In this case, an explanation of the FIELDNAME attribute appears.

The following objects may appear on the Field View tab.

The Segment View tab shows a hierarchy of segments on the left, with the attributes and values of the selected item on the right, as seen in the following image.

The List View tab shows a list of objects on the left, with the attributes and values of the selected item on the right, as shown in the following image.

When you right-click a segment in the Synonym Editor, the shortcut menu shown in the following image appears in both the Field View and Segment View tabs. This image shows a SQL data source with the root segment selected.

The following options are available:

When you right-click a column in the Synonym Editor, a shortcut menu appears in both the Field View and List View tabs. The following image shows a SQL data source with a column selected.

Note: If you multi-select columns and right-click them, an abridged version of the shortcut menu opens.

The following options are available:

The Modeling View tab shows a graphical representation of the synonym, as shown in the following image. Use the Modeling View to define dimensions for OLAP analysis, view join properties, create cluster joins, and add or edit segments.

The Text View tab shows the description of the underlying table.

You can print the synonym syntax by selecting Print from the Application menu.

The image below is an example of an MS SQL Server data source in the Text View tab.

The Access File Text View tab shows the description of the Access File for a synonym, which is used to access the database.

Note: You can print the synonym syntax by selecting Print from the Application menu.

The image below is an example of an SQL data source in the Access File Text View tab.

Note: While you can edit the text views, it is highly recommended that you do so with care. Editing the synonym incorrectly can invalidate the synonym.
