从python连接到Azure分析服务

Question

我有Azure分析服务实例，使用表格模型，我需要通过DAX或MDX从python脚本查询数据。

我从Azure获得了一个看起来像这样的连接字符串：

Provider=MSOLAP;Data Source=asazure://eastus.asazure.windows.net/mymodel;Initial Catalog=mycatalog;User [email protected];Password=mypass;Persist Security Info=True;Impersonation Level=Impersonate

我尝试使用pyodbc连接到该连接字符串：

import pyodbc

connection_str = "Provider=MSOLAP;Data Source=asazure://eastus.asazure.windows.net/mymodel;" \
                 "Initial Catalog=mycatalog;User [email protected];Password=mypass;" \
                 "Persist Security Info=True;Impersonation Level=Impersonate"

my_connection = pyodbc.connect(connection_str)

我收到了这个错误：

Traceback (most recent call last):
  File "C:/workspace/test.py", line 7, in <module>
    my_connection = pyodbc.connect(connection_str)
pyodbc.InterfaceError: ('IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified (0) (SQLDriverConnect)')

Process finished with exit code 1
