Send html report per email from sqlplus

Your business partner wants to receive some daily mail with an sql query output in it. It does not need to be ultra-fancy, but some colors and titles would not hurt.

Here is the report in SQL:


select dname, sum(sal) from emp join dept using (deptno) group by rollup(dname);

Ok, let’s do the report within sqlplus.

rep.sql


set echo off numf 999G999G999G999 lin 32000 trims on pages 50000 head on feed off markup html off
alter session set nls_numeric_characters='.''' nls_date_format='Day DD. Month, YYYY';
spool /tmp/rep.html
prompt To: laurentschneider@example.com
prompt From: laurentschneider@example.com
prompt Subject: Daily department report
prompt Content-type: text/html
prompt MIME-Version: 1.0
set markup html on entmap off table 'BORDER="2" BGCOLOR="pink"'
prompt <i>Good morning, </i>
prompt <i>Here is the department report per &_DATE</i>
prompt <i>Kind Regards, </i>
prompt <i>Your IT Operations</i>

prompt <br/><h3>List of departments with the total salaries of their employees</h3>
select dname "Department", sum(sal) "Salary" from emp join dept using (deptno) group by rollup(dname);
spool off
host /usr/sbin/sendmail -t </tmp/rep.html
quit

Then simply call it from sqlplus (you may want to configure the sendmail part)

SQL> @rep

check your mail :

To: laurentschneider@example.com
From: laurentschneider@example.com
Subject: Daily department report
Good morning,

Here is the department report per Friday 15. April , 2011

Kind Regards,

Your IT Operations



List of departments with the total salaries of their employees

Department Salary
ACCOUNTING 8’750
RESEARCH 10’875
SALES 9’400
  29’025

It is pretty easier to maintain than APEX, but the capabilities are not that rich…

track ddl change (part 2)

I wrote about tracking ddl changes with a trigger there : track ddl changes

Another option is to use auditing.

A new and cool alternative is to use enable_ddl_logging (11gR2). This will track all ddl’s in the alert log

ALTER SYSTEM SET enable_ddl_logging=TRUE

Then later you issue

create table t(x number)

and you see in the alertLSC01.log

Tue Apr 05 14:43:32 2011
create table t(x number)

Wait, that’s not really verbose !?

Remember the alert log is just there for backward compatibility, it is time you start looking in the xml file :-)

There is not really much more there but the module, which indeed reveals someone is using TOAD to access my database !
