[英]pyodbc connection to MS SQL Server running on a docker container
pyodbc doesn't seem to be able to connect when trying to connect through specifying Driver.尝试通过指定驱动程序进行连接时,pyodbc 似乎无法连接。 I am able to connect to setting up a DSN but I also want to make connection when user has got the Driver, Server, UID, PWD and Database details.我能够连接以设置 DSN,但我还想在用户获得驱动程序、服务器、UID、PWD 和数据库详细信息时建立连接。
I am on Mac and and using FreeTDS driver.我在 Mac 上并且使用 FreeTDS 驱动程序。
freetds.conf freetds.conf
[MYMSSQL]
host = 0.0.0.0
port = 1433
tds version = 7.3
odbcinst.ini odbcinst.ini
[FreeTDS]
Description=FreeTDS Driver for Linux & MSSQL
Driver=/usr/local/lib/libtdsodbc.so
Setup=/usr/local/lib/libtdsodbc.so
UsageCount=10
Here is how I am trying to connect:这是我尝试连接的方式:
conn_str = "DRIVER=FreeTDS;SERVER={0};UID={1};PWD={2};DATABASE={3}".format('MYMSSQL', 'sa', 'password','tempdb')
conn = pyodbc.connect(conn_str)
The error I get is this:我得到的错误是这样的:
pyodbc.OperationalError: ('08001', '[08001] [FreeTDS][SQL Server]Unable to connect to data source (0) (SQLDriverConnect)')
Exact same database details work when I try to connect through DSN.当我尝试通过 DSN 连接时,完全相同的数据库详细信息工作。
If you have a freetds.conf file containing the host name/IP and port, eg,如果您有一个包含主机名/IP 和端口的 freetds.conf 文件,例如,
gord@xubuntu64-nbk1:~$ cat /etc/freetds/freetds.conf
[myFreeTdsHost]
host = 192.168.0.179
port = 49242
then you can use both of those values in your DSN-less connection string by simply specifying the SERVERNAME=
然后您可以通过简单地指定SERVERNAME=
在无 DSN 的连接字符串中使用这两个值
# get host name/IP and port from freetds.conf
cnxn_str = (
'DRIVER=FreeTDS_ODBC;'
'SERVERNAME=myFreeTdsHost;'
'DATABASE=myDb;'
'UID=sa;PWD=_whatever_;'
)
You can also supply the host name/IP and port directly via SERVER=
and PORT=
like so您还可以像这样直接通过SERVER=
和PORT=
提供主机名/IP 和端口
# supply host name/IP and port directly (bypassing freetds.conf)
cnxn_str = (
'DRIVER=FreeTDS_ODBC;'
'SERVER=192.168.0.179;'
'PORT=49242;'
'DATABASE=myDb;'
'UID=sa;PWD=_whatever_;'
)
