DB Navigator

DB Navigator shows the entire database structure as a tree with expandable nodes.

DB Navigator Toolbar

Icon Tool Tip Description

Back and Forward

Retrace your steps. Navigate between hyperlinked database objects and their dependent objects and components. Move between—

  • An object and its dependencies, and vice-versa
  • An index or trigger and the table to which it refers, and vice-versa
  • A collector type and the base type of table it is related to
  • A synonym and its base object

You can also use the Forward and Back buttons in conjunction with Up One Level.

Up One Level

Change hierarchy levels in the DB Navigator tree.

TIP: Use Back to return to the level where you first used moved up.

DB Navigator Preferences

Set and Save filters to limit the objects displayed in the tree.

Open the Filter Properties Dialog.

Fully Expand Node from DB Expand the selected DB Navigator node and all its descendants.
Refresh from Current Node Refresh the selected DB Navigator node.

Show/Hide Details Panel

Show / Hide details about the selected DB Navigator node.

  • When you select a Schema node or Object Type node (for example, Tables or Indexes) the details pane shows a list of objects contained in that node. This list allows for selection of multiple objects for batch operations like Drop, Extract DDL, or Compile.
  • When you select a specific object the details pane shows attributes of the selected object.

 

Using DB Navigator

DB Navigator displays all types of Oracle objects, giving you a hierarchical view of any schema, including dependent objects. The tree view includes nodes for "My Schema," "All Schemas," and "Current Instance."

This symbol

Indicates

The node can be expanded.

Click + to drill down to underlying objects or data.

Alternatively, press the right arrow key or the space bar while the node is selected.

The node can be collapsed.

Click the – sign.

Alternatively, press the left arrow key while the node is selected.

(Grayed text)

The database object at that node is disabled or offline.

(Red text)

The database object at that node is invalid.

 

TIP:

  • Drag objects or connections that you use frequently to the Project Manager for fast access.
  • Double click on an object to open it for editing (Visual Object Editors, Code Editor).
  • Further commands are available on a selected object (or objects). Try the Object Menu. Right click on the object.
  • When a property is a reference to another database object (for example the base table for an index, or synonym's base object), click on the reference in the Value column to jump to the referenced object's node and display its properties.
  • To move around in the Navigator window you can use the keyboard arrow keys. Use Page Up and Page Down to scroll multiple lines.
  • To purge objects: Select the object(s) in the Recycle Bin and right click Purge. Alternatively, right-click on the Recycle Bin node and select Empty Recycle Bin.

  • To copy an object from one schema to another:

    1. Open a second DB Navigator window.
    2. Drag the object from the source window to the target window.
    3. Execute the DDL displayed in the editing window
  • To switch to another session's DB Navigator window, select the session and click View | DB Navigator.
  • Your view of the Oracle Data Dictionary determines what objects you can see. For more information, see DBA Dictionary Views.

Filter Properties Dialog

Create or modify DB Navigator filters that restrict the display of objects in the DB Navigator tree. You can save your filters, so that they will be available from the DB Navigator toolbar.

Select filter

Field Description
Filter Name Select an existing filter name or enter a new one.

 

Select filter settings.

Tab Description
General Selected schemas will be visible in the DB Navigator tree when the filter is applied.
Global Filters Selected top level nodes will be visible in DB Navigator when the filter is applied.

Object Filters

Selected object types will be visible in the DB Navigator window when the filter is applied.

Application of name masks

Type the name mask in the Filter box.

Name masks are specified according to Oracle’s LIKE operator definition. For example, setting the name mask ABC% will result in displaying only those objects with names beginning with the characters "ABC".

The name mask is applied to all selected object types. Click Assign Globally.to apply the name mask to all objects.

Describe

The Oracle DESCRIBE command reports the attributes, methods and arguments of an object type. The SQL Navigator Describe command works with more objects than does the SQL*Plus version of the command. You can describe not only procedures, functions, packages, synonyms, and object types, but also tables, indexes, clusters and objects.

To open the Describe window

Object Menu

  1. Ensure the required database connection is active.
  2. Select the database object.
  3. Click Object | Describe.
DB Navigator Right click the object in DB Navigator and select Describe.
Project Manager Right click the object in Project Manager and select Describe.
Code Editor Right click the object in Code Editor and select Describe Object at Cursor.
Shortcut Ctrl+F3

 

TIP: To keep the existing Describe window open while opening additional Describe windows, click the Pin toolbar icon in the Describe window. Set the default pin behavior in View | Preferences | General | User Interface.

  • Can be used to provide a quick summary of a table or view and all its column names and data types.

Tips to use the Describe window

A quick way to construct a SELECT statement

To drag column names into the Select statement

  1. In the editing window, click the cursor on the table name.
  2. Open the Describe window.
  3. Drag and drop column names from the Describe window into the SELECT statement.

Describe Command or Auto Describe Tool

Use either the Describe command or the Auto Describe Tool to describe an object

Auto Describe Tool

Automatically see a description of any object you select.

A dockable Describe window opens and stays on top of the application window.

As you select various objects you will automatically see a description of the selected object in the Auto Describe window.

Object | Describe

Click the Describe command on the Object menu whenever needed. It opens a describe window for a single selected object and will not update automatically when you select another object.

Difference Viewer

The Difference Viewer displays the compared objects in a split window. Differences between the objects are highlighted, and the toolbars and menus give you access to controls for customizing the view and creating reports.
