    <p>I'm trying to write a PL/SQL function that returns an array of integers and then be able to call it with cx_Oracles callfunc. I think I got the PL/SQL function right, but I don't know how to call it with cx_Oracle.</p> <p><code>create or replace type test_type is table of NUMBER(10);</code></p> <pre><code>create or replace function test_function (n in INTEGER) RETURN test_type AS tmp_tab test_type := test_type(); BEGIN tmp_tab.EXTEND(n); FOR i IN 1 .. n LOOP tmp_tab(i) := i; END LOOP; RETURN tmp_tab; END; </code></pre> <p>It works with sqlplus:</p> <pre><code>SQL&gt; select test_function(20) from dual; TEST_FUNCTION(20) -------------------------------------------------------------------------------- TEST_TYPE(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20) </code></pre> <p>How can I get the result of such function using cx_Oracle? Is that possible?</p> <p>I've found this <a href="http://osdir.com/ml/python.db.cx-oracle/2005-06/msg00014.html" rel="nofollow">http://osdir.com/ml/python.db.cx-oracle/2005-06/msg00014.html</a> but I don't realy know how to use it. When I change my type definition to:</p> <pre><code>create or replace type test_type is table of NUMBER(10) index by binary_integer; </code></pre> <p>I get: Warning: Type created with compilation errors.</p> <pre><code>SQL&gt; sho err Errors for TYPE TEST_TYPE: LINE/COL ERROR -------- ----------------------------------------------------------------- 0/0 PL/SQL: Compilation unit analysis terminated 1/19 PLS-00355: use of pl/sql table not allowed in this context </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
