如题，环境是 python 3.6 + django 1.11 + sqlserver 2008 安装服务器 centos7 +nginx 查询英文表，英文 sql 语句正常，列是中文也可以正常显示，查询中文视图报错如执行 select [名字] from [报告单视图]会报错
python3 manage.py shell
from django.db import connections
conn = connections['mssqldb']
cur = conn.cursor()
cur.execute('SELECT TOP 1 name FROM vw_report')
<pyodbc.Cursor object at 0xac1b528>
cur.fetchall()
cur.execute("SELECT top 1 [姓名] FROM [接口视图_报告结果] where [姓名]='郎秀兰'") #报错
cur.fetchall()
/etc/odbc.ini 修改内容为这样
[ODBC Data Sources]
ODBCNAME = Microsoft SQL Server
[MSSQL-PYTHON]
Driver = /usr/lib64/libtdsodbc.so
Description = Hi! This is a description of the MSSQL-PYTHON driver

client charset = UTF-8
/etc/odbcinst.ini 修改内容为这样

/etc/freetds.conf 此文件修改编码 client charset = GB2312 无效果，改 utf8 也试过不对！

django settings.py 配置如下
'mssqldb': {

'HOST': '127.0.0.1',
'PORT': '1433',
'USER': 'sa',
'PASSWORD': '*********',
'OPTIONS': {

},
其他配置
LANGUAGE_CODE = 'zh-Hans'
TIME_ZONE = 'Asia/Shanghai'
报如下错误

django 访问引用数据报如下错误

大哥，这个已经很明显了好吧。。。中文出错基本上就是字符编码问题，你看下面的 column name，都是乱码，一看就知道是编码问题啊。。。
具体如何解决就 Google 吧。 /etc/odbcinst.ini 和 /etc/freetds.conf 这两个应该都要同步改吧？ 还有，在 sqlserver 里面查询一下表的编码是什么，应该能解。 具体怎么查询 Google。 |
