Oracle JDeveloper 188.8.131.52.0 Generates Invalid SQL Scripts in Alter Mode from Offline Database
(Doc ID 1086390.1)
Last updated on FEBRUARY 25, 2021
Applies to:Oracle JDeveloper - Version 184.108.40.206.0 and later
Information in this document applies to any platform.
When working with Offline Databases in JDeveloper 220.127.116.11.0 the "generate to" function generates a SQL script but with some code that is causing errors in ALTER mode.
For a simple column, JDeveloper generates the following, and is not expected:
Drop column X
Add column X1 (same as X)
Rename column X1 to X
Expected would be that the DROP and ADD commands are not generated.
Steps to reproduce the issue using JDeveloper 18.104.22.168.0
- Create new GENERIC application
- Choose "Database (Offline) in the Project Technologies.
- Click "Finish"
- Create new Project
- Choose "Offline Database Objects" in Tab "Current Technologies" in List "Categories"
- Choose "Offline Database" in List "Items"
- Name Database "Test"
- Choose Oracle10g R1 for Database emulation
- Click OK
- Generate Database connection. Use any schema, for example any test schema provided by Oracle.
- Right-click in Application Navigator on Item "Test"
- Choose "Copy to Projects" from the context menu
- Choose the Database connection, which you created on step 10.
- On "Specify Target" the default should be ok.
- On "Object Picker" click "Query" to get the whole schema
- Then put all objects from the left list to the right list.
- On "Choose Operation" leaf the default (should be CREATE) and click finish.
- Right click on any offline table and choose "duplicate..." and Rename it to any unique name (for instance "TABLE2"). Then click OK.
- Double click on the new table, rename a Column adding a numeric prefix (for instance COL to COL2)
- Add new Unique Constrains for another column.
- Click OK.
- Right click on the newly created offline table (TABLE2) and Choose "Generate to..."->"SQL-script".
- Choose "ALTER" and then finish. (this is the ONLY option)
Then, repeat the following steps:
24. Right click on the offline table and choose "Generate to..." -> "SQL-script".and
25. Choose "ALTER" and then click finish. (No other options are needed).
After that you will see the number added and the ADD and DROP commands.
