mysql-python fetchrow brings: TypeError: 'long' object is not callable

Question

I got a table:

+-----------+-------------+------+-----+---------+-------+
| Field     | Type        | Null | Key | Default | Extra |
+-----------+-------------+------+-----+---------+-------+
| Benutzer  | varchar(50) | YES  |     | NULL    |       |
| Confirmed | tinyint(1)  | YES  |     | NULL    |       |
+-----------+-------------+------+-----+---------+-------+

with one entry!

If I execute on the mysql console in a shell:

select Benutzer from UserConfirm where Benutzer = '\{\'gid\'\:\ \'tamer\'\,\ \'uid\'\:\ \'tamer\'\}'

it works!

At mysql-python there comes the errormessage:

TypeError: 'long' object is not callable

What did I make wrong?! Here is my python code:

cursor = self.__db.cursor().execute('select * from UserConfirm where Benutzer = \'' + ds + '\'') 
return cursor().fetchrow()

For any advice, I would kindly thank you.

Answer 1

The problem is that you are not storing the cursor object, just the return value of execute, which is not the cursor, it should be:

cursor = self.__db.cursor()
cursor.execute('select * from UserConfirm where Benutzer = \'' + ds + '\'') 
return cursor.fetchone()

Answer 2

Note that I assume your line cursor().fetchrow() is a typo and you meant cursor.fetchrow().

Not knowing mysql-python myself, from the error I can assume cursor.execute is returning the number of rows or an error code, not the cursor itself.

Try the following instead:

cursor = self.__db.cursor()
cursor.execute('select * from UserConfirm where Benutzer = \'' + ds + '\'')
return cursor.fetchrow()
