Entity Relationship Model for PL/Scope

Today I found a sketch of an ERD from last year when I looked at the new features of PL/Scope in version 12.2. It looked a bit complicated and also wrong. So, I decided to refactor it using SQL Developer Data Modeler and share the result. You find the model in the […]

Limitations of PL/Scope and How to Deal with Them

My first car was a Renault R5 TX. The motor cooling of this car was really bad. On a hot summer day, it was simply not possible to drive slowly in high traffic without overheating the engine. To cool the engine you could either stop the car, open the front lid and […]

Simplify the Use of PL/Scope in SQL Developer

In this post, I showed how to do some code analysis with PL/Scope and how the views and packages of the plscope-utils might simplify this task. However, these views and packages are based on dba_* views and it is sometimes not that easy to get such privileges for an additional user in a non-personal database instance. […]

plscope-utils – Utilities for PL/Scope

PL/Scope was introduced with Oracle Database version 11.1 and covered PL/SQL only. SQL statements such as SELECT, INSERT, UPDATE, DELETE and MERGE were simply ignored. Analysing PL/SQL source code without covering SQL does not provide a lot of value. Hence, PL/Scope was neglected by the Oracle community. But this seems to change with […]

Bitemp Remodeler v0.1.0 Released

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 […]

How to Integrate Your PL/SQL Generators in SQL Developer

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 […]

Outer Join Operator (+) Restrictions in 12.1.0.2?

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 […]

Trivadis PL/SQL & SQL CodeChecker for SQL Developer Released

A half a year ago Trivadis released a command line utility to scan code within a directory tree for guideline violations of the Trivadis PL/SQL & SQL Coding Guidelines Version 2.0. This tool is perfectly suited to process millions of lines of code, but an integration into Oracle SQL Developer was missing until now. […]
