I have created a variable named hash as a password hash. How can this variable be inserted a a field value in a table?

hash = pbkdf2_sha256.encrypt("password", rounds=200000, salt_size=16)
cur.execute("insert into meanu(username,pwdhash1) values('BV2',hash)")
produces following error:
mysql_exceptions.OperationalError: (1054, "Unknown column 'hash' in 'field list'")
mysql_exceptions.OperationalError: (1054, "Unknown column 'hash' in 'field list'")

cur.execute("insert into meanu(username,pwdhash1) values('BV2','hash')") inserts the literal "hash" as the field value.

  • I think you need quotes around hash – Mihai May 16 '15 at 6:46
  • Mihal, that doesn't insert the variable hash, but the entry is the literal word hash. – Bob Pynewby May 16 '15 at 7:59

    In which context are you using hash = ... and cur.execute(...) ? – DeadEye May 16 '15 at 8:03

You should insert hash as a parameter following this example: http://dev.mysql.com/doc/connector-python/en/connector-python-api-mysqlcursor-execute.html

Something like this

insert_stmt=(
       "insert into meanu (username,pwdhash1)"
       " values('BV2',%s)"
        )
data=(hash)
cursor.execute(insert_stmt, data)
  • Thank you very much! It works perfectly. Have a great weekend, Robert – Bob Pynewby May 16 '15 at 10:45
