PL/SQL & SQL Formatter Settings


This repository provides formatter settings for the coding style rules of the Trivadis PL/SQL & SQL Coding Guidelines.

Settings are primarily provided for

These settings have been defined and tested with the product versions mentioned above. They might not work in other versions.

JDK 8 or 11 is required for SQLDev and SQLcl. The standalone tvdformat.jar works with JDK 8, 11, 17.

See releases for settings supporting older versions.

Deviating Settings

Please note that these settings do not comply with rule 5. Line breaks are placed after a comma and not before. All other rules are followed. However, you can easily change this in the preferences.

Nice to Know

Lightweight Formatter

The Arbori program implements a lightweight formatter which accepts different coding styles. If you need a heavyweight formatter to enforce the conformity of your code, you will need to use the default Arbori program provided by the SQL Developer team.

In any case, you can use our SQLcl JavaScript format.js, the standalone formatter or the Git pre-commit hook to format your code.

Disable Formatter

The formatter is enabled by default. You can disable the formatter with a single-line or multi-line comment containing @formatter:off. From that point on, whitespace are kept as is. To re-enable the formatter use @formatter:on.

Supported Marker Comment Action Origin
@formatter:off Disables formatter Eclipse IDE
@formatter:on Enables formatter Eclipse IDE
noformat start Disables formatter PL/SQL Developer
noformat end Enables formatter PL/SQL Developer

The marker comments are case sensitive.

Here's an example showing the code after calling the formatter:

-- @formatter:off
select decode(dummy, 'X', 1 
                   , 'Y', 2
                   , 'Z', 3
                        , 0) /* @formatter:on */
  from dual;


SQL Developer uses its own parse tree query language called Arbori for its advanced formatter configuration. Here is some additional information that might be useful if you plan to tweak the behavior of the formatter yourself.


Thank you, Vadim Tropashko for providing this valuable information.

JavaScript Global Variables

To get the most out of the dynamic JavaScript actions from an Arbori program, you should know the following global variables and their corresponding Java class.

Variable Type JAR File
struct dbtools-common.jar
target oracle.dbtools.parser.Parsed dbtools-common.jar
tuple HashMap<String, oracle.dbtools.parser.ParseNode> dbtools-common.jar
logger oracle.dbtools.util.Logger dbtools-common.jar

Formatter settings are also provided for the following products:

Product Version File
Allround Automations PL/SQL Developer 14.0.6
JetBrains DataGrip 2021.1 trivadis.xml
