爲什麼我可以使用tsql而不是pymssql連接到Azure MS SQL？

Question

今天我在哪裏：

TDSVER=7.3 tsql -H example.database.windows.net -U me -D ExampleDB -p 1433 -P notreallymypassword 

這不：

>>> import pymssql 
>>> pymssql.connect('example.database.windows.net', user='me', password='notreallymypassword', database='ExampleDB', tds_version='7.3') 

它失敗

Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
    File "pymssql.pyx", line 635, in pymssql.connect (pymssql.c:10734) 
    File "_mssql.pyx", line 1902, in _mssql.connect (_mssql.c:21821) 
    File "_mssql.pyx", line 577, in _mssql.MSSQLConnection.__init__ (_mssql.c:6214) 
    File "_mssql.pyx", line 1704, in _mssql._tds_ver_str_to_constant (_mssql.c:18845) 
_mssql.MSSQLException: unrecognized tds version: 7.3 

好。那麼，那是......奇怪。所以我回去嘗試tsql使用TDSVER=7.2，這似乎工作正常。

試圖與tds_version='7.2'連接給我：

Traceback (most recent call last): 
    File "pymssql.pyx", line 635, in pymssql.connect (pymssql.c:10734) 
    File "_mssql.pyx", line 1902, in _mssql.connect (_mssql.c:21821) 
    File "_mssql.pyx", line 637, in _mssql.MSSQLConnection.__init__ (_mssql.c:6581) 
    File "_mssql.pyx", line 1630, in _mssql.maybe_raise_MSSQLDatabaseException (_mssql.c:17524) 
_mssql.MSSQLDatabaseException: (20002, b'DB-Lib error message 20002, severity 9:\nAdaptive Server connection failed (datawhse.database. 
windows.net:1433)\n') 

During handling of the above exception, another exception occurred: 

Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
    File "pymssql.pyx", line 641, in pymssql.connect (pymssql.c:10824) 
pymssql.OperationalError: (20002, b'DB-Lib error message 20002, severity 9:\nAdaptive Server connection failed (datawhse.database.windo 
ws.net:1433)\n') 

那麼，是什麼原因呢？

更新1： pyodbc 也連接失敗：

conn = pyodbc.connect('SERVER=example.database.windows.net;Driver=FreeTDS;UID=me@example.database.windows.net;PWD=notmyrealpassword;' 
, ansi=True) 

我的〜/ .odbcinst.ini：

[FreeTDS] 
Description  = MS SQL driver 
Driver   = /usr/lib64/libtdsodbc.so.0 
Driver64  = /usr/lib64/libtdsodbc.so.0 
Setup   = /usr/lib64/libtdsS.so.0 
Setup64   = /usr/lib64/libtdsS.so.0 
UsageCount  = 1 
CPTimeout  = 
CPReuse   = 
Trace   = Yes 

而這種輸出：

Answer 1

它看起來像戈登是正確的：問題是，pymssql輪沒有SSL綁定。

我卸載它：

python -m pip uninstall pymssql 

然後從源代碼安裝它：

python -m pip install --no-binary pymssql pymssql 

這需要我安裝幾個依賴關係。但現在我可以連接

pymssql.connect('example.database.windows.net', 
       user='me', 
       password='notreallymypassword', 
       database='ExampleDB', 
       tds_version='7.2') 

Answer 2

你的連接ction字符串看起來不正確。它應該是這樣的：

pymssql.connect(server='example.database.windows.net', user='me@example', password='notreallymypassword', database='ExampleDB') 

注意，在你的榜樣調用connect()，你缺少一個server=參數;你只有完整的服務器名稱。
