Constants
- PGError
Backward-compatible aliase
- PGconn
The PostgreSQL connection class. The interface for this class is based on libpq, the C application programmer's interface to PostgreSQL. Some familiarity with libpq is recommended, but not necessary.
For example, to send query to the database on the localhost:
require 'pg' conn = PG::Connection.open(:dbname => 'test') res = conn.exec_params('SELECT $1 AS a, $2 AS b, $3 AS c', [1, 2, nil]) # Equivalent to: # res = conn.exec('SELECT 1 AS a, 2 AS b, NULL AS c')
See the PG::Result class for information on working with the results of a query.
