    <p>I have the following information with me:</p> <pre><code>The EMP table is as follows: EMPNO , ENAME, JOB, MGR, HIREDATE, SAL,COMM,DEPTNO Here is the DEPT table: DEPTNO, DNAME, LOC </code></pre> <p>Based on the following question:</p> <p><strong>create a table to log employee terminations. Include the empno, emp name, the date hired, the date terminated, and the name of the oracle user who terminated the employee.</strong></p> <p>I have created the following table in Oracle 11g, SQL Plus as follows:</p> <pre><code>CREATE TABLE employee_terminations_log( empno number(4), emp_name char(8), datehired date, dateterminated date, dbuser char(8) ); </code></pre> <p>Now, based on the following question :</p> <p><strong>Create a trigger on the emp table to insert relevant information into the employee termination log. The trigger must execute every time an employee is deleted.</strong></p> <p>I wrote the code for the trigger as follows:</p> <pre><code>create or replace trigger emp_termination_trigger after delete of empno on emp for each row begin insert into employee_termination-log values(:old.empno,:old.emp_name,:old.hiredate,sysdate,user); end; </code></pre> <p>But I'm getting the following error:</p> <pre><code>8 / after delete of empno on emp * ERROR at line 2: ORA-04073: column list not valid for this trigger type </code></pre> <p>Could anyone please tell me what's wrong in the above code for trigger? Basically I have to deleter the whole employee row and for that I have used the following statement in the above code. </p> <p>after delete of empno on emp</p> <p>Please let me know what's wrong.</p> <p>Thanks</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.
