Postgres psycopg2 create user

问题

To create a user through psycopg2, I am using the following code :

        cur=conn.cursor()
    cur.execute("create user %s with password %s",('abcdefgh','0h/9warrAttrgd8EF0gkvQ==',))

This gives the following error :

syntax error at or near "'abcdefgh'" LINE 1: create user 'abcdefgh' with password '0h/9warrAttrgd8EF0gkvQ.

It seems that %s is placing quotes around the username, which postgres doesn't like while creating a user. The following code works fine :

        cur.execute("create user abcdefgh with password %s",('0h/9warrAttrgd8EF0gkvQ==',))

Any workaround for this ?

回答1:

Use psycopg2.extensions.AsIs(object):

from psycopg2.extensions import AsIs

cur.execute("create user %s with password %s", (AsIs('abcdefgh'), '0h/9warrAttrgd8EF0gkvQ==',))
