Hashing rows…

Bar Solutions - Wed, 2010-09-15 17:05
During my work at the current customer site I was asked to create files with the changes to the data in the database. Normally you would use triggers on the tables to create logs of the records changed. Or use a Flashback Data Archive, which is only available starting Oracle 11G and I am working [...]

Report in APEX

Bar Solutions - Wed, 2010-09-15 17:05
The other day someone at a customer had a question about displaying a report. The different options are in a table so he could easily use a report to display the options. But he wanted to display three columns of options. That is, if there are 10 options, he would want to display 3 rows [...]

Custom Authentication Scheme In APEX

Bar Solutions - Wed, 2010-09-15 17:05
I have been playing around with Apex 4.0 on When playing around with some ideas I have for application I decided to use the logging mechanism I created a while ago, to see what’s going on in the custom code. Since this is a hosted environment it is not too easy to check the [...]

Top 10 Reasons to Develop in a VM

Jeff Kemp - Mon, 2010-08-30 01:00
The cost of providing Virtual Machines to all your developers can be quite high, especially in terms of initially setting it all up (e.g. a typical developer may require two VMs running concurrently, one for the database server, one for the app server; their desktops will require enough grunt to run these while they also [...]

Generate DML/DDL/QUERY from SQL – the easy way

Jeff Kemp - Wed, 2010-08-25 21:00
This is a comment on’s article “Generate DML/DDL/QUERY from SQL” – comments are not enabled on their blog so here’s my addendum. The following query is offered as a means of generating a script to ONLINE all datafiles in a database: select 'ALTER DATABASE DATAFILE '''|| name || ''' online ;' from v$datafile; I [...]

OPP 2010

Bar Solutions - Tue, 2010-08-24 23:39
On October 27th and 28th the combined OPP (Oracle PL/SQL Programming) and APEXposed conference is coming to Europe. To Brussels to be exact. I have had the privilege to attend these conferences since the first one in 2005. The nice thing about this conference is that it is the only conference (at least that I [...]

InSync10 Day 2

Jeff Kemp - Wed, 2010-08-18 08:00
Another good day in Melbourne. Heard Richard Foote talk about Indexing New Features in Oracle 11g release 1 and 2. One thing he demonstrated was the creation of an index on only part of a table – normally I’d use a function-based index for this sort of thing, but his technique results in an index [...]

Never satisfied

Jeff Kemp - Wed, 2010-08-18 03:00
So I followed the great advice here to use the new COLLECT function in Oracle 10g to solve the common string-aggregation-in-SQL problem. I chose this solution over the others because it sorts the results as well, which was a user requirement. This is because the COLLECT function optionally takes an ORDER BY clause – even [...]

InSync10 Day 1

Jeff Kemp - Mon, 2010-08-16 05:00
After a scrumptious breakfast at the Armoury I headed in what I believed was the general direction of the Melbourne Convention Centre – after making a wrong turn I eventually spotted a footbridge over the river that rung a bell from my GoogleEarthing; after taking some photos I was finally at InSync10. The first session [...]

Editing Oracle Reports

Jeff Kemp - Wed, 2010-08-11 01:00
If you’re like me, the above picture will probably have given you a frisson of dread. Just a little. The example here is not a very complicated report, just a few repeating groups based on quite a nice data model. What catches me every time, however, is a few little apparent quirks in Oracle Reports [...]

Directory File List in PL/SQL

Jeff Kemp - Tue, 2010-08-10 01:00
UTL_FILE, unfortunately, does not allow you to query the contents of a directory. One option is to create a java routine. Note: this is not my code – a colleague sent the basics to me and I’ve just modified it somewhat to suit my purpose. CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED "DirectoryLister" AS [...]

Purge all Recyclebins without SYSDBA

Jeff Kemp - Mon, 2010-08-09 01:00
Want to purge all the recyclebins for all users in your database? Can’t (or don’t want to) log in as each user individually to run this, one by one: PURGE RECYCLEBIN You could log in as SYSDBA and run: PURGE DBA_RECYCLEBIN But, what if you don’t have SYSDBA access? (Yes, this has happened to me, with [...]

In Oracle, ” = NULL but NULL != ”

Jeff Kemp - Wed, 2010-08-04 19:00
When I get the result of my PL/SQL quiz for the day, I’m pleased when I got it right, but if I got it wrong, I’m either annoyed or overjoyed: If I disagreed with the result, I’m annoyed. If I agreed with the result, I’m overjoyed – because I learned something new, or I was [...]

Tag wikis on StackOverflow

Jeff Kemp - Mon, 2010-08-02 01:00
StackOverflow now allows the creation of wiki articles and tag synonyms. I’ve gone ahead and started a few articles about a few topics dear to my heart: oracle plsql apex – synonyms: htmldb and application-express These articles are not intended to be replacements for the documentation or Wikipedia, but primarily as a guide for people [...]

The Templating Way

Jeff Kemp - Thu, 2010-07-29 18:00
Today, grasshopper, you will learn the Way of the Template. The Templating Way is the path by which complex output is produced in a harmonious fashion. The Templating Way does not cobble a string together from bits and pieces in linear fashion. htp.p('<HTML><HEAD><TITLE>'||:title ||'</TITLE></HEAD><BODY>' ||:body||'</BODY></HTML>'); The Templating Way separates the Template from the Substitutions; by this [...]
