show table oracle types or varray types in query results

[This topic is migrated from our old forums. The original author name has been removed]

I want to execute a query grouped by some column and show a collected column as a nested table in oracle (see https://docs.oracle.com/database/121/SQLRF/functions034.htm#SQLRF06304 for more information about collect). The query executes fine, but the collected column is shown as null. When I execute the same query in a java application using jdbc, I am able to show the results of the nested table (see https://docs.oracle.com/cd/B28359_01/java.111/b31224/oraarr.htm#BABDEJBJ for more information about how to retrieve data from an oracle.sql.ARRAY type in jdbc). As an example, I create a customers and a bankaccounts table: create table customers ( id number(6) not null primary key , name varchar2(30) not null , birthdate date not null ); create table bankaccounts ( nr number(10) not null primary key , customer_id number(6) not null , current_balance number(14,2) not null ); ... and populate it: insert into customers select 1, 'Jeffrey Lebowski', date '1964-01-01' from dual union all select 2, 'Walter Sobchak', date '1961-01-01' from dual; insert into bankaccounts select 123456789, 1, 10 from dual union all select 987654321, 1, 100 from dual union all select 234567890, 2, 2000 from dual; I also create a nested table type: CREATE TYPE myNumberTableType AS TABLE OF number(14,2); ... and finally execute the following query: select c.id, c.name, cast(collect (b.current_balance) as myNumberTableType) as collectedBalances from customers c inner join bankaccounts b on b.customer_id = c.id group by c.id, c.name; This executes fine, but the last column only shows nulls: ID NAME COLLECTEDBALANCES -- ---------------- ----------------- 1 Jeffrey Lebowski (null) 2 Walter Sobchak (null) I also tried the same using a VARRAY: CREATE TYPE myNumberArrayType AS VARRAY(10) OF number(14,2); ... and execute the query like the following: select c.id, c.name, cast(collect (b.current_balance) as myNumberArrayType) as collectedBalances from customers c inner join bankaccounts b on b.customer_id = c.id group by c.id, c.name; ... but I still get the same results. I'm using dbViz 9.1.7 using oracle thin driver using ojdbc7-12.1.0.2.0.jar. Is dbViz supposed to support nested tables and varrays in queries? Best regards Jan

Hi Jan, DbVisualizer currently does not support displaying nested tables. We have an open ticket for looking into this and I have added your vote for this feature. Best Regards, Hans Edited by: Hans Bergsten on Mar 31, 2016 9:52 PM
