使用IronPython在SQL Server Analysis Services上执行查询 [英] Execute query on SQL Server Analysis Services with IronPython

问题描述

我能够使用Microsoft.AnalysisServices.dll使用Python连接到SQL Server Analysis Service，现在我无法在多维数据集上执行查询.

I was able to connect to SQL server Analysis service in Python using Microsoft.AnalysisServices.dll, and now I can't execute query on cube.

我尝试了与以下相同的Execute方法:

I've tried Execute method same as following:

amoServer.Execute('select from finance')

发出Execute方法后，出现此错误:

After issuing Execute method I have this error:

<Microsoft.AnalysisServices.XmlaError object at 0x000000000000002B [Microsoft.AnalysisServices.XmlaError]>

注意:我正在Windows Server 64Bit上使用IronPython和Python 2.7.

Note: I'm using IronPython with Python 2.7 on Windows Server 64Bit.

出什么问题了?

推荐答案

最好使用 Microsoft.AnalysisServices.AdomdClient.dll 和 mdx 查询. 并在 Ststem.Data 程序集中的数据集中设置查询结果 像这样的东西:

its better use Microsoft.AnalysisServices.AdomdClient.dll and mdx query. and set query result in Datasets in Ststem.Data assembly something like this:

clr.AddReference ("Microsoft.AnalysisServices.AdomdClient.dll")
clr.AddReference ("System.Data")

from Microsoft.AnalysisServices.AdomdClient import AdomdConnection , AdomdDataAdapter
from System.Data import DataSet

conn = AdomdConnection("Data Source=0.0.0.0;Catalog=MyCatalog;")
conn.Open()
cmd = conn.CreateCommand()
cmd.CommandText = "your mdx query" # in your case 'select from finance'
adp = AdomdDataAdapter(cmd)
datasetParam =  DataSet()
adp.Fill(datasetParam)
conn.Close();

# datasetParam hold your result as collection a\of tables
# each tables has rows
# and each row has columns
print datasetParam.Tables[0].Rows[0][0]
