我认为我的问题或多或少与Trying to query SQL Server from django running on Linux - Can't open lib '/path/to/libtdsodbc.so'重复,但答案完全没有用。
我正在使用以下内容:
Python3
Django 1.9
(通过pip3安装)freetds-dev 0.91-6build1
通过apt-get django-pyodbc-azure
/ django-pyodbc
尝试连接时,执行python3 manage.py inspectdb
我得到以下堆栈跟踪:
Traceback (most recent call last):

pyodbc.Error: ('01000', "[01000] [unixODBC][Driver Manager]Can't open lib 'FreeTDS' : file not found (0) (SQLDriverConnect)")
The above exception was the direct cause of the following exception:

我已经编辑了base.py来打印出它使用的连接字符串,即:
DRIVER=FreeTDS;DATABASE=test;PWD=test;UID=sa;PORT=1433;SERVER=10.13.36.223
我的数据库的settings.py如下:
DATABASES = {
'default': {
'ENGINE': 'sql_server.pyodbc',
'NAME': 'test',
'USER': 'sa',
'PASSWORD': 'test',
'HOST': '10.13.36.223',
'PORT': '1433',
'AUTOCOMMIT': True,
'OPTIONS' : {
'host_is_server': True
}
}
}
我的假设是连接str的DRIVER
部分应该是odbc驱动程序的可执行文件的完全限定路径,现在它已设置为&#34; FreeTDS&#34 ;,它不作为文件存在。我的问题是:
答案 0 :(得分:6)
我需要做以下事情:
sudo apt-get install tdsodbc
/etc/odbcinst.ini
以包含以下内容:
[FreeTDS]
Description = TDS Driver for MSSQL
driver = /usr/lib/x86_64-linux-gnu/odbc/libtdsodbc.so
setup = /usr/lib/x86_64-linux-gnu/odbc/libtdsS.so
它有效。
答案 1 :(得分:3)
上述[FreeTDS]配置非常有用。
在settings.py DATABASE会话中,我还添加了驱动程序版本以及unicode结果设置。这是我的配置:
DATABASES = {
'default': {
'ENGINE': 'sql_server.pyodbc',
'NAME': 'myDataBaseNameInMSSQLServer',
'USER': 'mssql-user-with-SQL-authentication',
'PASSWORD': 'password',
'HOST': 'server-host-name-or-IP\\SQLEXPRESS',
'PORT': '1433',
'OPTIONS' : {
'AUTOCOMMIT': True,
'host_is_server': True,
'unicode_results': True,
'driver': 'FreeTDS',
'extra_params' : 'TDS_VERSION=8.0',
}
}
}
对于SQL Express,您还需要Google搜索如何使该实例可用于远程连接。
