SQL Service
===========

Description
-----------

SQL service stores all its data in database. It can use one of these SQL backends
(configuration option :config:option:`Driver` in smsd section):

* ``native_mysql`` for :ref:`gammu-smsd-mysql`
* ``native_pgsql`` for :ref:`gammu-smsd-pgsql`
* ``odbc`` for :ref:`gammu-smsd-odbc`
* drivers supported by DBI for :ref:`gammu-smsd-dbi`, which include:
    * ``sqlite3`` - for SQLite 3
    * ``mysql`` - for MySQL
    * ``pgsql`` - for PostgeSQL
    * ``freetds`` - for MS SQL Server or Sybase

SQL connection parameters
-------------------------

Common for all backends:

* :config:option:`User` - user connecting to database
* :config:option:`Password` - password for connecting to database
* :config:option:`Host` - database host or data source name
* :config:option:`Database` - database name
* :config:option:`Driver` - ``native_mysql``, ``native_pgsql``, ``odbc`` or DBI one
* :config:option:`SQL` - SQL dialect to use

Specific for DBI:

* :config:option:`DriversPath` - path to DBI drivers
* :config:option:`DBDir` - sqlite/sqlite3 directory with database

.. seealso:: The variables are fully described in :ref:`gammurc` documentation.

.. _SQL Queries:

SQL Queries
-----------

Almost all queries are configurable. You can edit them in
:config:section:`[sql]` section. There are several variables used in SQL
queries. We can separate them into three groups:

* phone specific, which can be used in every query, see :ref:`Phone Specific Parameters`
* SMS specific, which can be used in queries which works with SMS messages, see :ref:`SMS Specific Parameters`
* query specific, which are numeric and are specific only for given query (or set of queries), see :ref:`Configurable queries`
