# example for connecting to a PostgreSQL server: db.connect driver=pg database=mydb db.login user=myname password=secret host=myserver.osgeo.org # port=5432 db.connect -p db.tables -p
The file .pgpass in a user's home directory can contain passwords to be used if the connection requires a password (and no password has been specified otherwise). On Microsoft Windows the file is named %APPDATA%\postgresql\pgpass.conf (where %APPDATA% refers to the Application Data subdirectory in the user's profile). Alternatively, a password file can be specified using the connection parameter passfile or the environment variable PGPASSFILE. This file should contain lines of the following format:
hostname:port:database:username:password
db.execute sql="ALTER TABLE mytable ADD ID integer" db.execute sql="CREATE SEQUENCE mytable_seq" db.execute sql="UPDATE mytable SET ID = nextval('mytable_seq')" db.execute sql="DROP SEQUENCE mytable_seq"
\h copy COPY t1 FROM 'filename' USING DELIMITERS ',';
CREATE TABLE test ( id serial NOT NULL, mytime timestamp DEFAULT now(), text varchar, wkb_geometry geometry, CONSTRAINT test_pkey PRIMARY KEY (id) ) WITHOUT OIDS; # insert value INSERT INTO test (text, wkb_geometry) VALUES ('Name',geometryFromText('POLYGON((600000 200000,650000 200000,650000 250000,600000 250000,600000 200000))',-1)); # register geometry column select AddGeometryColumn ('postgis', 'test', 'geometry', -1, 'GEOMETRY', 2);
