[s_m_l_x]

since 0.90 in windows, if i use execute() to search some data , when i fetch row i have get this exception :

Traceback (most recent call last):
  File "<pyshell#12>", line 1, in <module>
    cur.fetchone()

if i use oursql0.1 these is no problem, i dont know what happen

I have the same issue.

So I'm having a hell of a time reproducing this error. If I could get a minimal broken example of this, it would be fantastic.

[aqua (vhx)]

This simple database and table cause the problem for me.

There are no rows in that table. Please provide the full contents of the table, the python source used to generate the error, and the complete traceback.

[aqua (vhx)]

Yes there are no rows. It produces the same exact error, with or without any rows at all. It is simply a test database that produces the problem for me.

The code that produces the problem:
import oursql

host = '127.0.0.1'
port = 3303
user = 'test'
pw = 'test'
db = 'test'

db = oursql.connect(host=host, user=user, passwd=pw, db=db, port=port)

print "SQL Connection Established on %s:%s" % (host, port)

cursor = db.cursor()

cursor.execute("""SELECT * FROM `item_db`""");

rows = cursor.fetchall()

for row in rows:
            print row

[aqua (vhx)]

Sorry, last code is incorrect. The below code is copy-pastable to produce the error for me.

import oursql

host = '127.0.0.1'
port = 3303
user = 'test'
pw = 'test'
db = 'test'

database = oursql.connect(host=host, user=user, passwd=pw, db=db, port=port)

print "SQL Connection Established on %s:%s" % (host, port)

cursor = database.cursor()

cursor.execute("""SELECT * FROM `item_db`""");

rows = cursor.fetchall()

for row in rows:
    print row

I am having the exact same issue on windows:

>>> import oursql
>>> conn = oursql.connect(user="root",
        db="test",
        passwd="password", port=3306,host="127.0.0.1")
>>> cursor = conn.cursor()
>>> cursor.execute("SELECT * FROM `ip_addr`")
>>> cursor.fetchall()

Traceback (most recent call last):
  File "<pyshell#10>", line 1, in <module>
    cursor.fetchall()
  File "cursor.pyx", line 228, in oursql.Cursor.fetchall (oursqlx/oursql.c:16568)

InterfaceError: (2036, 'Using unsupported buffer type: 3 (parameter: 3)', None)

the database is not empty - not that it should make any difference.

[lobe (sharpblade1)]

Also I am running a 64 bit mysql server, and using the 32 bit connector (and the 32 bit compiled oursql binaries).

[Danny McRae (khjklujn)]

I encountered this problem also, however, when I built the package from source instead of using the distributed binary, the problem went away. One big clue as to where the problem may be is that I had to edit setup.py to look for version 5.1 in the registry rather than version 5.0.
