    <p>Suppose I have an <code>AFTER ALTER</code> trigger on my Oracle database and I rename some database object (<code>ALTER ... RENAME TO ...</code>). Within the trigger, how do I determine the <strong>new</strong> name of the database object? It seems that the <code>ORA_DICT_OBJ_OWNER</code>, <code>ORA_DICT_OBJ_NAME</code> and <code>ORA_DICT_OBJ_TYPE</code> functions all return the <strong>old</strong> values of the database object.</p> <p>For example:</p> <pre><code>CREATE OR REPLACE TRIGGER ADAM_BEFORE_AFTER BEFORE ALTER ON DATABASE BEGIN DBMS_OUTPUT.put_line('Before alter: ' || ora_dict_obj_owner || '.' || ora_dict_obj_name || ' (' || ora_dict_obj_type || ')'); END; CREATE OR REPLACE TRIGGER ADAM_AFTER_ALTER AFTER ALTER ON DATABASE BEGIN DBMS_OUTPUT.put_line('After alter: ' || ora_dict_obj_owner || '.' || ora_dict_obj_name || ' (' || ora_dict_obj_type || ')'); END; </code></pre> <p>Suppose I rename a table:</p> <pre><code>ALTER TABLE USELESS_TABLE9 RENAME TO USELESS_TABLE10 </code></pre> <p>The database outputs this:</p> <pre> Before alter: DEVELOPER.USELESS_TABLE9 (TABLE) After alter: DEVELOPER.USELESS_TABLE9 (TABLE) </pre> <p><strong>Update:</strong> Unfortunately, the output I presented above was incorrect. The output was actually being generated by a <code>BEFORE DDL</code> trigger and an <code>AFTER DDL</code> trigger I had created earlier, <strong>not</strong> by the <code>BEFORE RENAME</code> and <code>AFTER RENAME</code> triggers. I will continue to investigate why the <code>BEFORE RENAME</code> and <code>AFTER RENAME</code> triggers are not firing...</p> <p><strong>Update:</strong> It appears that the <code>BEFORE RENAME</code> and <code>AFTER RENAME</code> triggers refuse to fire, but the <code>BEFORE ALTER</code> and <code>AFTER ALTER</code> triggers do. I have updated the question accordingly.</p>

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.
