The SQL Linter for humans

image image image codecov CircleCI

Bored of not having a good SQL linter that works with whichever dialiect you're working with? Fluff is an extensible and modular linter designed to help you write good SQL and catch errors and bad SQL before it hits your database.

Getting Started

To get started just install the package, make a sql file and then run sqlfluff and point it at the file.

$ pip install sqlfluff
$ echo "  SELECT a  +  b FROM tbl;  " > test.sql
$ sqlfluff lint test.sql
== [test.sql] FAIL
L:   1 | P:   1 | L003 | Single indentation uses a number of spaces not a multiple of 4
L:   1 | P:  14 | L006 | Operators should be surrounded by a single space unless at the start/end of a line
L:   1 | P:  27 | L001 | Unnecessary trailing whitespace

Usage

For more details on usage see the docs on github here.
