A ‘quick’ question came in this morning: “Jeff, does SQL Developer show contents of Object type columns? I’m advised not…

I wanted to say ‘Yes’ and then just run away laughing maniacally, but I thought maybe I should put together a quick example instead. So here goes. And by the way, welcome to 2013 everyone 🙂

Creating a USER TYPE

From the DOCS


Create and Populate a Table using the new Type

CREATE TABLE demo_tab1 (b1 NUMBER, b2 demo_typ1);
INSERT INTO demo_tab1 VALUES (1, demo_typ1(2,3));

Querying and Viewing the TYPE data using SQL Developer

Now I’m not a fan of ‘SELECT *’ from queries, but in this case I’ll give you a pass. Or, just open the table editor in the connection tree and go to the Data tab. I’ll use the SELECT * from method.

Click on the ‘Pencil’ icon to drill into the object type data.

So a quick and dirty post, but now I have one less scenario to code up when needing to answer FAQ SQL Developer questions 🙂

  1. is it possible to get the same output as in SQL Plus to this select * from demo_tab1?
    I mean to see data without using “Click on the ‘Pencil’ icon to drill into the object type data.” but actual data

    Thanks, It solved my problem. I just recompiled the types and now I can see the objects values in debug tab.

  3. Hi Jeff,
    Many times when we debug object types which are inherited from a base Oracle object type sqldeveloper will show it as OPAQUE. Can you please guide on this regard.


    • Sounds like that OBJECT TYPE hasn’t been compiled with DEBUG. And make sure all of the dependent objects have been. At least, that’s what I would check first.

    …and when will we be able to see the contents of types and tables of types when debugging PL/SQL? (Or if this is already possible but I’m doing something wrong, please let me know!)
