Adaptive Server连接失败：使用pymssql

如何解决Adaptive Server连接失败：使用pymssql

我可以使用sqlcmd连接到sql Server：

sqlcmd -S xxxxxmssqlserver.database.windows.net,1433 -U xxxadministrator -P thxxxxx

但是，当我使用Python脚本时，它不起作用。

import pymssql

conn = pymssql.connect(server='xxxxxxmssqlserver.database.windows.net',user='mradministrator',password='thxxxx',database='AdventureWorks')
cursor = conn.cursor()
cursor.execute('SELECT c.CustomerID,c.CompanyName,COUNT(soh.SalesOrderID) AS OrderCount FROM SalesLT.Customer AS c LEFT OUTER JOIN SalesLT.SalesOrderHeader AS soh ON c.CustomerID = soh.CustomerID GROUP BY c.CustomerID,c.CompanyName ORDER BY OrderCount DESC;')
row = cursor.fetchone()
while row:
    print str(row[0]) + " " + str(row[1]) + " " + str(row[2])
row = cursor.fetchone()

错误消息是

[testadmin @ vic1-deployment] $ python test.py
追溯（最近一次通话）：

文件“ test.py”，第3行，在
conn = pymssql.connect（server ='xxxxmssqlserver.database.windows.net'，user ='xxxadministrator @ xxxxmssqlserver'，password ='xxxxx'，database ='Master'）

pymssql.connect中的文件“ src / pymssql.pyx”，第642行，
pymssql.OperationalError：（20002，'DB-Lib错误消息20002，严重性9：\ nAdaptive Server连接失败xxxxxmssqlserver.database.windows.net）\ n'）

根据以下建议进行环境检查！ Environment Requirements

[testadmin@vic1 deployment]$ tsql -C
Compile-time settings (established with the "configure" script)
                            Version: freetds v0.91
             freetds.conf directory: /usr/local/freetds/etc
     MS db-lib source compatibility: yes
        Sybase binary compatibility: no
                      Thread safety: yes
                      iconv library: yes
                        TDS version: 5.0
                              iODBC: no
                           unixodbc: yes
              sspI "trusted" logins: no
                           Kerberos: no

我在连接参数中使用了以下内容：

user='xxxadministrator@xxxxmssqlserver'
database='Master'

但是我不知道如何检查TDS protocol version以及是否检查FreeTDS is built with SSL support。但是，我从TDS version的输出中看到5.0是tsql -C。
