Lightweight Formatter for PL/SQL & SQL

TL;DR Bye bye heavyweight formatter. Long live the lightweight formatter. Are you using Oracle’s SQL Developer or SQLcl? Then install these settings and press Ctrl-F7 to produce code that conforms to the Trivadis PL/SQL & SQL Coding Style. A compromise between conformity and individuality.

Work From Home – First Anniversary

Patching SQL Developer 20.2 with SQLcl’s Formatter

Introduction SQLcl 20.3.0 was released on October 29, 2020. It’s the first time I remember that we have a SQLcl version without the corresponding SQL Developer version.

Disable Formatter for Code Sections in SQL Developer

In this blog post I show how you can disable the formatter for some parts of your code. IntelliJ IDEA and the Eclipse IDE use tags in comments to identify sections of code that must not be formatted. By default these tags are @formatter:off and @formatter:on. Example [crayon-6196c84067d53335587392/] When I format this […]
