"""pgdb - DB-API 2.0 compliant module for PyGreSQL.
(c) 1999, Pascal Andre <andre@via.ecp.fr>.
See package documentation for further information on copyright.
Inline documentation is sparse.
See DB-API 2.0 specification for usage information:
http://www.python.org/peps/pep-0249.html
Basic usage:
pgdb.connect(connect_string) # open a connection
# connect_string = 'host:database:user:password:opt'
# All parts are optional. You may also pass host through
# password as keyword arguments. To pass a port,
# pass it in the host keyword parameter:
connection = pgdb.connect(host='localhost:5432')
cursor = connection.cursor() # open a cursor
cursor.execute(query[, params])
# Execute a query, binding params (a dictionary) if they are
# passed. The binding syntax is the same as the % operator
# for dictionaries, and no quoting is done.
cursor.executemany(query, list of params)
# Execute a query many times, binding each param dictionary
# from the list.
cursor.fetchone() # fetch one row, [value, value, ...]
cursor.fetchall() # fetch all rows, [[value, value, ...], ...]
cursor.fetchmany([size])
# returns size or cursor.arraysize number of rows,
# [[value, value, ...], ...] from result set.
# Default cursor.arraysize is 1.
cursor.description # returns information about the columns
# [(column_name, type_name, display_size,
# internal_size, precision, scale, null_ok), ...]
# Note that display_size, precision, scale and null_ok
# are not implemented.
cursor.rowcount # number of rows available in the result set
# Available after a call to execute.
connection.commit() # commit transaction
connection.rollback() # or rollback transaction
cursor.close() # close the cursor
connection.close() # close the connection
