SQLint - a simple SQL linter


SQLint is a simple command-line linter which reads your SQL files and reports any syntax errors or warnings it finds.

At this stage, SQLint checks SQL against the ANSI syntax, and uses the PostgreSQL SQL parser to achieve this. SQLint does not have support for non-standard SQL variants (e.g. MySQL), but contributions are welcome.


SQLint is currently provided as a ruby gem: you can install it using the following command:

gem install sqlint


To check the syntax of a file containing SQL, simply pass the filename to sqlint on the command line:

sqlint filename.sql

In the absence of a filename, sqlint reads from standard input.
