python - psycopg2.ProgrammingError: syntax error at or near "\" -


i have python module copy data table file.im using postgresql database server. copy command used above action.

however in blog (http://grokbase.com/t/postgresql/pgsql-general/058tagtped/about-error-must-be-superuser-to-copy-to-or-from-a-file) states that, can use \copy in 'psql' on client side, have superuser copy on server side, security reasons. used \copy command. when try execute below method, results in error

psycopg2.programmingerror: syntax error @ or near "\" line 1: \copy

i can't find why throwing error. can me out?

def process():      query="\copy %s %s"%('test_table', 'test_file.txt')       @env.with_transaction()      def do_execute(db):          cursor = db.cursor()          cursor.execute(query)

do_execute database wrapper, creates connection , executes query.

\ escape in python strings, string contains escape \c. \c invalid escape in python, , python leaves invalid escapes unchanged, "\copy" \copy. (thus @tiziano's answer misleading).

>>> print "\c" \c

the real problem \copy psql command, not server side postgresql command. can't use client other psql. must instead use the psycopg2 support copy via client driver.

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
