How connect to mysql with python via odbc

Im running mysql, pyodbc, python 2.7 loaded on Fedora 14 x64.

Odbcinst.ini is:

# Example driver definitions

# Driver from the postgresql-odbc package
# Setup from the unixODBC package
#[PostgreSQL]
#Description    = ODBC for PostgreSQL
#Driver     = /usr/lib/psqlodbc.so
#Setup      = /usr/lib/libodbcpsqlS.so
#Driver64   = /usr/lib64/psqlodbc.so
#Setup64    = /usr/lib64/libodbcpsqlS.so
#FileUsage  = 1


# Driver from the mysql-connector-odbc package
# Setup from the unixODBC package
[MySQL]
Description = ODBC for MySQL
#Driver     = /usr/lib/libmyodbc5.so
#Setup      = /usr/lib/libodbcmyS.so
Driver64    = /usr/lib64/libmyodbc5.so
Setup64     = /usr/lib64/libodbcmyS.so
FileUsage   = 1

Odbc.ini is :

[MySQL]
Driver = MySQL
Database = mysql
Server = localhost
Socket = /var/lib/mysql/mysql.sock
User = rooter
Password = sshh

Mysql.sock is empty? /var/lib/mysql/mysql.sock has 0.B

python script is:

import pyodbc

#pyodbc.pooling = False 
conn = pyodbc.connect('DRIVER={MySQL};SOCKET=/var/lib/mysql/mysql.sock开发者_如何学C;UID=rooter;PWD=sshh') 

csr = conn.cursor()
csr.execute("SET GLOBAL event_scheduler = ON")
csr.close()

conn.close() 
del csr

I cant seem to connect with above script, Using isql i get Connected!

MyERROR msg:

Traceback (most recent call last):
  File "/CCX/Py/MySql Event OFF.py", line 4, in <module>
    conn = pyodbc.connect('DRIVER={MySQL};SOCKET=/var/lib/mysql/mysql.sock;UID=rooter;PWD=sshh') 
pyodbc.Error: ('IM002', '[IM002] [unixODBC][Driver Manager]Data source name not found, and no default driver specified (0) (SQLDriverConnectW)')

On Win XPx64,

#cxn = MySQLdb.connect (host = "localhost",user="rooter",passwd ="sshh")

Err Msg:

File "C:\Python26\lib\site-packages\MySQLdb\__init__.py", line 19, in <module>
    import _mysql
ImportError: DLL load failed: %1 is not a valid Win32 application.

Comparing odbcinst.ini and your odbc.ini show an odd value for driver in odbc.ini, you should have a dynamic library here (I think).

And why don't you use direct mysql connection (without odbc)? :

import _mysql

conn = _mysql.connect(host="localhost", user="rooter", 
                      password="sshh", db="mysql") 
conn.query("SET GLOBAL event_scheduler = ON")
conn.close() 

(not tested)

File "C:\Python26\lib\site-packages\MySQLdb__init__.py", line 19, in import _mysql ImportError: DLL load failed: %1 is not a valid Win32 application.

if Python26 && windows we need download 3 files : libguide40.dll, libmmd.dll, libmySQL.dll put the 3 files to C:\Python26\Lib\site-packages and also put the 3 files to C:\Windows\system32 then restart your system

if Python27 && windows when you setup the module ,be careful the version MySQL-python-1.2.3.win32-py2.7.exe MySQL-python-1.2.4.win32-py2.7.exe one of the 2 version is you need

code tested:

import _mysql

conn=_mysql.connect(host="localhost", user="root", passwd="***", db="test")
conn.query("select * from test_table")
result = conn.use_result()

print result.fetch_row()

The fetch_row() function has two parameters:

1. maxrows limits the max number of rows returned.
2. how: it returns a tuple when how=0 and returns a dictionary when how=1.

For example, result.fetch(maxrows=5, how=1) returns an array (maximum size: 5) of dictionaries where the key is the column name and the value is the column value.
