# The SQL Linter for Humans

[](https://hub.docker.com/r/sqlfluff/sqlfluff)
**SQLFluff** is a dialect-flexible and configurable SQL linter. Designed
with ELT applications in mind, **SQLFluff** also works with Jinja templating
and dbt. **SQLFluff** will auto-fix most linting errors, allowing you to focus
your time on what matters.
## Dialects Supported
Although SQL is reasonably consistent in its implementations, there are several
different dialects available with variations of syntax and grammar. **SQLFluff**
currently supports the following SQL dialects (though perhaps not in full):
- ANSI SQL - this is the base version and on occasion may not strictly follow
the ANSI/ISO SQL definition
- [Athena](https://aws.amazon.com/athena/)
- [BigQuery](https://cloud.google.com/bigquery/)
- [ClickHouse](https://clickhouse.com/)
- [Databricks](https://databricks.com/) (note: this extends the `sparksql` dialect with
[Unity Catalog](https://docs.databricks.com/data-governance/unity-catalog/index.html) syntax).
- [Db2](https://www.ibm.com/analytics/db2)
- [DuckDB](https://duckdb.org/)
- [Exasol](https://www.exasol.com/)
- [Greenplum](https://greenplum.org/)
- [Hive](https://hive.apache.org/)
- [Materialize](https://materialize.com/)
- [MySQL](https://www.mysql.com/)
- [Oracle](https://docs.oracle.com/en/database/oracle/oracle-database/21/sqlrf/index.html)
- [PostgreSQL](https://www.postgresql.org/) (aka Postgres)
- [Redshift](https://docs.aws.amazon.com/redshift/index.html)
- [Snowflake](https://www.snowflake.com/)
- [SOQL](https://developer.salesforce.com/docs/atlas.en-us.soql_sosl.meta/soql_sosl/sforce_api_calls_soql.htm)
- [SparkSQL](https://spark.apache.org/docs/latest/)
- [SQLite](https://www.sqlite.org/)
- [Teradata](https://www.teradata.com/)
- [Transact-SQL](https://docs.microsoft.com/en-us/sql/t-sql/language-reference) (aka T-SQL)
- [Trino](https://trino.io/)
- [Vertica](https://www.vertica.com/)
We aim to make it easy to expand on the support of these dialects and also
add other, currently unsupported, dialects. Please [raise issues](https://github.com/sqlfluff/sqlfluff/issues)
(or upvote any existing issues) to let us know of demand for missing support.
Pull requests from those that know the missing syntax or dialects are especially
welcomed and are the question way for you to get support added. We are happy
to work with any potential contributors on this to help them add this support.
Please raise an issue first for any large feature change to ensure it is a good
fit for this project before spending time on this work.
## Templates Supported
SQL itself does not lend itself well to [modularity](https://docs.getdbt.com/docs/viewpoint#section-modularity),
so to introduce some flexibility and reusability it is often [templated](https://en.wikipedia.org/wiki/Template_processor)
as discussed more in [our modularity documentation](https://docs.sqlfluff.com/en/stable/perma/modularity.html).
**SQLFluff** supports the following templates:
- [Jinja](https://jinja.palletsprojects.com/) (aka Jinja2)
- SQL placeholders (e.g. SQLAlchemy parameters)
- [Python format strings](https://docs.python.org/3/library/string.html#format-string-syntax)
- [dbt](https://www.getdbt.com/) (requires plugin)
Again, please raise issues if you wish to support more templating languages/syntaxes.
## VS Code Extension
We also have a VS Code extension:
- [Github Repository](https://github.com/sqlfluff/vscode-sqlfluff)
- [Extension in VS Code marketplace](https://marketplace.visualstudio.com/items?itemName=dorzey.vscode-sqlfluff)
# Getting Started
To get started, install the package and run `sqlfluff lint` or `sqlfluff fix`.
```shell
$ pip install sqlfluff
$ echo " SELECT a + b FROM tbl; " > test.sql
$ sqlfluff lint test.sql --dialect ansi
== [test.sql] FAIL
L: 1 | P: 1 | LT01 | Expected only single space before 'SELECT' keyword.
| Found ' '. [layout.spacing]
L: 1 | P: 1 | LT02 | First line should not be indented.
| [layout.indent]
L: 1 | P: 1 | LT13 | Files must not begin with newlines or whitespace.
| [layout.start_of_file]
L: 1 | P: 11 | LT01 | Expected only single space before binary operator '+'.
| Found ' '. [layout.spacing]
L: 1 | P: 14 | LT01 | Expected only single space before naked identifier.
| Found ' '. [layout.spacing]
L: 1 | P: 27 | LT01 | Unnecessary trailing whitespace at end of file.
| [layout.spacing]
L: 1 | P: 27 | LT12 | Files must end with a single trailing newline.
| [layout.end_of_file]
All Finished 📜 🎉!

# Releases
**SQLFluff** adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html),
so breaking changes should be restricted to major versions releases. Some
elements (such as the python API) are in a less stable state and may see more
significant changes more often. For details on breaking changes and how
to migrate between versions, see our
[release notes](https://docs.sqlfluff.com/en/latest/perma/releasenotes.html). See the
[changelog](CHANGELOG.md) for more details. If you would like to join in, please
