Request: compare and propagate user objects

Question

After making changes to table definitions, views, program units, and so on, it may be useful to propagate these changes to another database user. This maybe another development environment, or a testing environment in same or another database. Like "Compare user objects" option in PLSQL/Developer.

Compare User Objects
After making changes to table definitions, views, program units, and so on, it may be useful to propagate these changes to another database user. This maybe another development environment, or a testing environment. To compare the objects of your development user with another user, you can use the Compare User Objects function in the Tools menu. This will bring up the following dialog:
On the Selection tab page you can select the objects you wish to compare. After making this selection, you can press the Target Session button, to select the user and database that you want to compare. This will enable the Compare button, which you can press to start the compare operation. You can select the Include storage... option to include the storage information such as tablespace names and initial sizes for new objects. These may differ across databases, so this may not always be appropriate.
When the compare operation is finished, the dialog will switch to the Differences tab page, which will show a list of all objects that are different:
This list is sorted in order of dependency. Below the list of different objects of the target user, you see the SQL that needs to be executed to make these objects equal to the corresponding objects of the current user. If no object is selected, the SQL of all objects is displayed. If one or more objects are selected, only the SQL for the selected object(s) is displayed. In the example above, a missing EMP_MGR_EMPNO check constraint was added to the EMP table.
The Show Differences button will show a visual line-by-line difference of the old and new source file of an object. This can be useful to view the changes made in Program Units, or can help you determine why a specific DDL statement was generated for other object types. The Configure External Difference Tool allows you to configure the difference tool should be used. By default the ExamDiff utility will be used, for which a Pro version is available (See the About item of ExamDiff’s Info menu). See also Tools - Differences.
You can now press the Apply SQL button to execute this SQL in the target session. You can alternatively save the SQL in a file by pressing the Save SQL button, or you can copy it to the clipboard by pressing the Copy SQL button.
When objects are compared, the following properties are ignored:
·     Storage – Properties such as the next extent and pct free of tables and indexes are not considered relevant for comparison.
·     Constraints with system generated names – These constraints will have different names for the 2 users, so they cannot be compared. If a table is new in the target session, these constraints will be generated though.
·     Table creation properties – Properties that would require the recreation of the table are ignored.
·     Table data – To export table data, use the Export Table function (see Export Tables).
·     Sequence values – The current value of a sequence is considered data.

This is on the list but not for 1.0.
