postgresql - python - how to properly quote sql string -


how quote string postgres sql syntax within python script uses psycopg2's cur.execute ("select .. ")

postgres sql:

select 'alter table rename ' || tablename || ' ' ||    regexp_replace ( tablename, '_foo$', '_bar' ) || ';' pg_tables tablename '%_foo';

within python script:

  cur.execute("select 'alter table rename ' || tablename || ' ' ||                 regexp_replace ( tablename, '_foo$', '_bar' ) || ';'                 pg_tables                 tablename '%_foo'")

simply, add line breaks:

cur.execute("select 'alter table rename ' || tablename || ' ' || \              regexp_replace ( tablename, '_foo$', '_bar' ) || ';' \              pg_tables \              tablename '%_foo'")
