The PL/SQL Cop tool suite supports the new Trivadis PL/SQL & SQL Coding Guidelines 3.2. Download the new versions from the Download section. So, what’s new? Numbering and Categorisation Scheme The guidelines have been renumbered, extended, categorised by severity (blocker, critical, major, minor and info) and assigned to one or more SQALE characteristics (changeability, […]

I’ve been working on a flexible table API generator for Oracle Databases for several months. A TAPI generator doesn’t sound like a real innovation. But this one contains some features you probably have not seen before in the TAPI generator and hopefully will like it as much as I do. In this post, I will […]

The latest version 3.1 of the Trivadis PL/SQL & SQL Coding Guidelines has 150 pages. More than 90 additional pages compared to version 2.0. Roger Troller did a tremendous job in updating and extending an already comprehensive document while making it simpler to read and easier to understand. In this post, I will […]

About three weeks ago Steven Feuerstein tweeted in his tip #501 a link to a generator for the WHEN clause in DML triggers on Oracle Live SQL. Back then I refactored the generator for oddgen – the Oracle community’s dictionary-driven code generator – and published the result on Oracle Live SQL as well. Some […]

Until August 2015 it never occurred to me that one could use non-PL/SQL code within conditional compilation blocks. Back then we discussed various template engine options as the foundation for oddgen – the Oracle community’s dictionary-driven code generator. oddgen supports nowadays the in-database template engines FTLDB and tePLSQL. Both tools may access templates stored in PL/SQL packages using a […]

Last week I presented the PL/SQL Cop tool suite to a customer in Germany. While preparing the demo I had taken my first deeper look at the PL/SQL Cop SonarQube plugin, written by Peter Rohner, a fellow Trivadian. I was impressed by how well the additional PL/SQL Cop metrics integrate into SonarQube and how easy […]

I’m currently reviewing a draft of Roger Troller’s updated PL/SQL and SQL Coding Guidelines version 3.0. One guideline recommends using ANSI join syntax. The mentioned reasons are ANSI join syntax does not have as many restrictions as the ORACLE join syntax has. Furthermore ANSI join syntax supports the full outer join. A third […]

Some people asked me to announce the availability of new versions of products on my website. I guess a blog entry and a Twitter announcement should do the job. Today I’ve released the following three updates: These products are always affected by a grammar change to SQL*Plus, SQL or PL/SQL. The goal is to […]

I’m using from time to time the free service Unwrap it! or Niels Teusink’s Python script unwrap.py to unwrap PL/SQL code. Recently I’ve been confronted more with wrapped code since a customer is about to migrate to a new banking platform which is using wrapped PL/SQL code extensively. While investigating migration errors we experienced that […]
