Databases¶

Two databases are supported: sqlite and postgresql. The database URLs follow the django url convention. The following features are supported in both databases:

Schema parsing of tables, columns, primary keys, foreign keys and unique indexes
Compound primary and foreign keys
SQL generation

Sqlite¶

Use the sqlite:/// prefix in front of the path name.

For a relative path use e.g.

sqlite:///test-db.sqlite3

For an absolute path use e.g.

sqlite:////var/lib/databases/test-db.sqlite3

Postgresql¶

A full postgresql URL is something like:

postgresql://user:password@host:port/dbname

host and dbname are required and password and port are optional. This is e.g. a valid url

postgresql://test_user@localhost/test_database

The generated SQL always starts with a BEGIN, ends with a COMMIT and has an extra \set ON_ERROR_STOP for convenience, so that a full SQL result looks something like:

BEGIN;
\set ON_ERROR_STOP
INSERT INTO ...
COMMIT;
