Getting started

GnrSqlDb is the main class of gnr.sql.gnrsql module. A GnrSqlDb instance has the following purposes:

• manage the logical structure of a database, called database's model.
• manage operations on db at high level, hiding adapter's layer and connections.

First of all you have to create a GnrSqlDb instance:

mydb = GnrSqlDb(implementation='sqlite', dbname='example', 
                user='foo', password='bar')

The constructor method has the following parameters:

• implementation: at this time there are only adapters for Sqlite or Postgres.
• dbname: the database name.
• host: the address of the db.
• user: user name.
• password: password.
• port: connection port
• main_schema: the main_schema of db
