DBI Backend¶

Description¶

DBI backend stores all data in any database supported by libdbi, which parameters are defined by configuration (see SMSD Configuration File for description of configuration options).

For tables description see SMSD Database Structure.

This backend is based on SQL Service.

Note

The DBI driver is currently not supported on Windows because libdbi library does not support this platform.

Configuration¶

Before running gammu-smsd you need to create necessary tables in the database. You can use examples given in database specific backends parts of this manual to do that.

The configuration file then can look like:

[smsd]
service = sql
driver = DBI_DRIVER
host = localhost

Supported drivers¶

For complete list of drivers for libdbi see libdbi-drivers project. The drivers for example include:

sqlite3 - for SQLite 3
mysql - for MySQL
pgsql - for PostgeSQL
freetds - for MS SQL Server or Sybase

Creating tables for SQLite¶

SQL script for creating tables in SQLite database:

CREATE TABLE gammu (
  Version INTEGER NOT NULL DEFAULT '0' PRIMARY KEY
);

INSERT INTO gammu (Version) VALUES (17);

CREATE TABLE inbox (
  UpdatedInDB NUMERIC NOT NULL DEFAULT (datetime('now')),
  ReceivingDateTime NUMERIC NOT NULL DEFAULT (datetime('now')),
  Text TEXT NOT NULL,

  CHECK (Coding IN

  END;

CREATE TABLE sentitems (

CREATE INDEX sentitems_date ON sentitems(DeliveryDateTime);
CREATE INDEX sentitems_tpmr ON sentitems(TPMR);
CREATE INDEX sentitems_dest ON sentitems(DestinationNumber);
CREATE INDEX sentitems_sender ON sentitems(SenderID);

CREATE TRIGGER update_sentitems_time UPDATE ON sentitems 
  BEGIN
    UPDATE sentitems SET UpdatedInDB = datetime('now') WHERE ID = old.ID;
  END;

Note

You can find the script in docs/sql/sqlite.sql as well. There are also scripts for other databases in same folder.

Upgrading tables¶

The easiest way to upgrade database structure is to backup old one and start with creating new one based on example above.

For upgrading existing database, you can use changes described in History of database structure and then manually update Version field in gammu table.
