Oracle SQL Developer中未显示DDL更改

Question

I have sql Upgrade script which has many sql statements(DDL,DML). When i ran this upgrade script in SQL developer, it runs successufully.I also provide in my script at the bottom commit. I can see all the changes in the database after running this upgrade script except the unique index constraints. When i insert few duplicate records it says unique constraint violated. It means the table has unique constraints. But i dont know why i cant view this constraints in oracle sql developer. The other DDL changes made i can view.I dont know is there any settings to view it in oracle sql developer.

CREATE UNIQUE INDEX "RATOR_MONITORING"."CAPTURING_UK1" ON "RATOR_MONITORING"."CAPTURING" ("DB_TABLE"); 
CREATE UNIQUE INDEX "RATOR_MONITORING_CONFIGURATION"."BRAND_UK1" ON "RATOR_MONITORING_CONFIGURATION"."BRAND" ("NAME");
CREATE UNIQUE INDEX "RATOR_MONITORING_CONFIGURATION"."BRAND_BUSINESS_PROCESS_UK1" ON "RATOR_MONITORING_CONFIGURATION"."BRAND_BUSINESS_PROCESS" ("BRAND_ID", "BP_ID");
CREATE UNIQUE INDEX "RATOR_MONITORING_CONFIGURATION"."BRAND_ENGINE_UK1" ON "RATOR_MONITORING_CONFIGURATION"."BRAND_ENGINE" ("BRAND_ID", "ENGINE_ID");

Answer 1

As A Hocevar noted, if you create an index

 create unique index test_ux on test(id);

you see it in the Indexes tab of the table properties (not in the Constraints tab).

Please note that COMMIT is not required here, it is done implicitely in each DDL statement. More usual source of problems are stale metadata in SQL Developer, ie missing REFRESH (ctrl R on user or table node).

If you want to define the constraint, add following statement, that will reuse the index defined previously

 alter table test add constraint test_unique unique(id) using index test_ux;

See further discussion about the option in Documentation

I am assuming you are trying to look for index on a table in the correct tab in sql developer. If you are not able to see the index there, one reason could be that your user (the one with which you are logged in) doesn't have proper rights to see the Index.

If you not obtain any error, the solution is very simple and tedious. SQL Developer doesn't refresh his fetched structures. Kindly push Refresh blue icon (or use Ctrl-R) in Connections view or disconnect and connect again (or restart SQL Developer) to see your changes in structures.
