我在Fedora 14 x64上运行mysql,pyodbc,python 2.7。
Odbcinst.ini是:
# 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是:
[MySQL]
Driver = MySQL
Database = mysql
Server = localhost
Socket = /var/lib/mysql/mysql.sock
User = rooter
Password = sshh
Mysql.sock是空的? /var/lib/mysql/mysql.sock有0.B
python脚本是:
import pyodbc
#pyodbc.pooling = False
conn = pyodbc.connect('DRIVER={MySQL};SOCKET=/var/lib/mysql/mysql.sock;UID=rooter;PWD=sshh')
csr = conn.cursor()
csr.execute("SET GLOBAL event_scheduler = ON")
csr.close()
conn.close()
del csr
我似乎无法连接上面的脚本,使用isql我得到了连接!
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)')
在Win XPx64上,
#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.

比较odbcinst.ini
和您的odbc.ini
在odbc.ini
中显示驱动程序的奇数值,您应该在这里有一个动态库(我认为)。
你为什么不use direct mysql connection(没有odbc)? :
import _mysql
conn = _mysql.connect(host="localhost", user="rooter",
password="sshh", db="mysql")
conn.query("SET GLOBAL event_scheduler = ON")
conn.close()
(未经测试)

文件&#34; C:\ Python26 \ lib \ site-packages \ MySQLdb__init __。py&#34;,第19行,in import _mysql ImportError:DLL加载失败:%1不是有效的Win32应用程序。
如果Python26&amp;&amp;视窗 我们需要下载3个文件:libguide40.dll,libmmd.dll,libmySQL.dll 将3个文件放到C:\ Python26 \ Lib \ site-packages中 并将3个文件放到C:\ Windows \ system32 然后重启你的系统
如果Python27&amp;&amp;视窗 设置模块时,请注意版本 MySQL的 - 蟒蛇-1.2.3.win32-py2.7.exe MySQL的 - 蟒蛇-1.2.4.win32-py2.7.exe 你需要的2个版本之一

代码测试:
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()
fetch_row()
函数有两个参数:
maxrows
限制返回的最大行数。how
:当how = 0时返回一个元组,并在how = 1时返回一个字典。例如,result.fetch(maxrows=5, how=1)
返回一个字典数组(最大值:5),其中键是列名,值是列值。
