    这是一个创建于 2527 天前的主题,其中的信息可能已经有所发展或是发生改变。

    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  
    Trace = No  
    #Database = cxonline  
    Server = 192.168.123.93 
    Port = 1433  
    Setup = /usr/lib64/libtdsS.so
    FileUsage = 1
    client charset = UTF-8
    

    /etc/odbcinst.ini 修改内容为这样

    [FreeTDS]
    Description = FreeTDS
    Driver = /usr/lib64/libtdsodbc.so
    
    [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  
    Trace = No  
    #Database = cxonline  
    Server = 192.168.123.93 
    Port = 1433  
    Setup = /usr/lib64/libtdsS.so
    FileUsage = 1
    client charset = UTF-8
    

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

    [192.168.1.108]
    host = 192.168.123.93
    port = 1433
    tds version = 8.0
    client charset = GB2312
    
    
    [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  
    Trace = No  
    #Database = cxonline  
    Server = 192.168.123.93 
    Port = 1433  
    

    django settings.py 配置如下

    'mssqldb': {
        'ENGINE': 'sqlserver',
        'NAME': 'data1',
        'HOST': '127.0.0.1',
        'PORT': '1433',
        'USER': 'sa',
        'PASSWORD': '*********',
        'OPTIONS': {
            'DRIVER': 'SQL Server Native Client 10.0',
        },
    

    其他配置

    LANGUAGE_CODE = 'zh-Hans'
    TIME_ZONE = 'Asia/Shanghai'
    

    报如下错误

    conn = connections['mssqldb'] cur = conn.cursor() cur.execute('SELECT TOP 1 reportid FROM vw_report') <pyodbc.Cursor object="" at="" 0x7fdbfb2c25d0=""> cur.fetchall() [(3.0, )] cur.execute("SELECT top 1 [姓名] FROM [接口视图_1] where [姓名]='郎秀兰'") Traceback (most recent call last): File "/usr/local/lib/python3.6/site-packages/django/db/backends/utils.py", line 63, in execute return self.cursor.execute(sql) File "/usr/local/lib/python3.6/site-packages/sql_server/pyodbc/base.py", line 545, in execute return self.cursor.execute(sql, params) pyodbc.ProgrammingError: ('42000', "[42000] [FreeTDS][SQL Server]Incorrect syntax near '='. (102) (SQLExecDirectW)")

    The above exception was the direct cause of the following exception:

    Traceback (most recent call last): File "<console>", line 1, in <module> File "/usr/local/lib/python3.6/site-packages/django/db/backends/utils.py", line 80, in execute return super(CursorDebugWrapper, self).execute(sql, params) File "/usr/local/lib/python3.6/site-packages/django/db/backends/utils.py", line 65, in execute return self.cursor.execute(sql, params) File "/usr/local/lib/python3.6/site-packages/django/db/utils.py", line 94, in exit six.reraise(dj_exc_type, dj_exc_value, traceback) File "/usr/local/lib/python3.6/site-packages/django/utils/six.py", line 685, in reraise raise value.with_traceback(tb) File "/usr/local/lib/python3.6/site-packages/django/db/backends/utils.py", line 63, in execute return self.cursor.execute(sql) File "/usr/local/lib/python3.6/site-packages/sql_server/pyodbc/base.py", line 545, in execute return self.cursor.execute(sql, params) django.db.utils.ProgrammingError: ('42000', "[42000] [FreeTDS][SQL Server]Incorrect syntax near '='. (102) (SQLExecDirectW)")

    django 访问引用数据报如下错误

    ProgrammingError at /Vresult/
    ('42S22', "[42S22] [FreeTDS][SQL Server]Invalid column name '鎶ュ憡鍗曞彿'. (207) (SQLExecDirectW)")

    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。

    @PureWhite 非常感谢回复,是编码问题,但是在哪里改才可以支持?我谷歌一圈没有找到,数据库是中午编码,兰亭字符集 lant ……,具体编码我一会查下,问题应该在 freetds 什么的编码,用 GB2312 及 UTF8 都乱码,已经找原因一个星期,查出数据中文显示正确,mssql 数据库服务器是 win10,数据库服务器安装 pymssql,可以查询,centos7 连接就不能!是否无解?

    @qile1 不是无解,字符编码虽然是一个比较麻烦的问题,但是也是很容易解决的。
    你自己都说了,数据库是中文编码,字符集是什么 兰亭(没听说过这个,我猜应该是 latin 吧。。。)?
    你要么就修改数据库的编码为 utf-8,要么就把配置里面的编码全部改成和数据库一样。
    包括记得 Django 的编码也得改,你在 python 里面调用的时候记得要 decode 或者 encode,根据你解决方案的不同。

    其实要做的事非常简单,就是把数据库,client 和你的 Django 的应用编码设置成一致就可以了。
