.. _dialect_toplevel:
Dialects
========
The **dialect** is the system SQLAlchemy uses to communicate with various types of :term:`DBAPI` implementations and databases.
The sections that follow contain reference documentation and notes specific to the usage of each backend, as well as notes
for the various DBAPIs.
All dialects require that an appropriate DBAPI driver is installed.
Included Dialects
-----------------
.. toctree::
:maxdepth: 1
:glob:
postgresql
mysql
sqlite
oracle
mssql
Support Levels for Included Dialects
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The following table summarizes the support level for each included dialect.
.. dialect-table:: **Supported database versions for included dialects**
:header-rows: 1
Support Definitions
^^^^^^^^^^^^^^^^^^^
.. glossary::
Fully tested in CI
**Fully tested in CI** indicates a version that is tested in the sqlalchemy
CI system and passes all the tests in the test suite.
Normal support
**Normal support** indicates that most features should work,
but not all versions are tested in the ci configuration so there may
be some not supported edge cases. We will try to fix issues that affect
these versions.
Best effort
**Best effort** indicates that we try to support basic features on them,
but most likely there will be unsupported features or errors in some use cases.
Pull requests with associated issues may be accepted to continue supporting
older versions, which are reviewed on a case-by-case basis.
Deprecated, no longer supported dialects
----------------------------------------
The following dialects have implementations within SQLAlchemy, but they are not
part of continuous integration testing nor are they actively developed.
These dialects are deprecated and will be removed in future major releases.
.. toctree::
:maxdepth: 1
:glob:
firebird
sybase
Note that both of these dialects now have third-party implementations that
are maintained separately. See the following list.
