Обсуждение: problem creating users via pythons script

this is really newb of me but i can't manage to make a script to create
users.

cur.execute("""CREATE USER %s WITH PASSWORD %s IN GROUP %s
""",(StaffUserName,NewPassword,StaffGroup))

produces this error

ERROR:  syntax error at or near "'bob.smith'" at character 13

is it because i need to double quote or something? i'm sure the answer
is stupid and i'm just too tired.

IIRC, per Python DB-API PEP, the DB adapter you use try to escape and
quote any parameter you specified. Please try to use python parameters,
that are "% (param1, param2, ...)", only for values; not for any other
place in the query string.

To summarize, you can only use parameters for values, not keys.

Edit: «% (param1, param2, ...)» part must be replaced with
      «"query_str", param1, param2, ...»

Just don't pass username as parameter to Cursor.execute(), for instance:

cur.execute("CREATE USER %s WITH PASSWORD %s IN GROUP %s"
            % (StaffUserName, NewPassword, StaffGroup))

P.S. Please don't forget to CC mailing list next time. Also, -interface
     ml is more appropriate for these kind of questions.
