This package is meant for accessing xmla datasources - see http://en.wikipedia.org/wiki/XML_for_Analysis
In your workdir run:
# create virtualenv
python3 -m venv xyz
cd xyz
source bin/activate
git clone https://github.com/may-day/olap
cd olap/xmla
# optional if you have it already
pip install pipenv
pipenv install -dev
python setup.py develop
# now you should be good to go
See HOWTO
Here is an example how to use it:
import olap.xmla.xmla as xmla
p = xmla.XMLAProvider()
# mondrian
c = p.connect(location="http://localhost:8080/mondrian/xmla")
# or ssas - note that thhis needs setup on an iis
# also you'll probably need to authenticate using kerberos
# from requests_kerberos import HTTPKerberosAuth
# c = p.connect(location="https://my-as-server/olap/msmdpump.dll",
# sslverify="/path/to/my/as-servers-ca-cert.pem", auth=HTTPKerberosAuth())
# getting info about provided data
print(c.getDatasources())
print(c.getMDSchemaCubes())
# for ssas a catalog is needed, so the call would be like
# get a catalogname from a call to c.getDBSchemaCatalogs()
# c.getMDSchemaCubes(properties={"Catalog":"a catalogname"})
# execute a MDX (working against the foodmart sample catalog of mondrian)
cmd= """
select {[Measures].ALLMEMBERS} * {[Time].[1997].[Q2].children} on columns,
[Gender].[Gender].ALLMEMBERS on rows
from [Sales]
"""
res = c.Execute(cmd, Catalog="FoodMart")
#return only the Value property from the cells
res.getSlice(properties="Value")
# or two props
res.getSlice(properties=["Value", "FmtValue"])
# to return some subcube from the result you can
# return all
res.getSlice()
# just the 4th column
res.getSlice(Axis0=3)
# same as above, SlicerAxis is ignored
res.getSlice(Axis0=3, SlicerAxis=0)
# return the data sliced at the 2nd and 3rd row
res.getSlice(Axis1=[1,2])
# return the data sliced at the 2nd and 3rd row and at the 4th column
res.getSlice(Axis0=3, Axis1=[1,2]) Using the procedural interface:
import olap.xmla.xmla as xmla
p = xmla.XMLAProvider()
c = p.connect(location="http://localhost:8080/mondrian/xmla")
s = c.getOLAPSource()
# import olap.interfaces as oi
# oi.IOLAPSource.providedBy(s) == True
s.getCatalogs()
s.getCatalog("FoodMart").getCubes()
s.getCatalog("FoodMart").getCube("HR").getDimensions()
s.getCatalog("FoodMart").getCube("HR").getDimension("[Department]").\
getMembers()
s.getCatalog("FoodMart").getCube("HR").getDimension("[Department]").\
getMember("[Department].[14]")
cmd= """
select {[Measures].ALLMEMBERS} * {[Time].[1997].[Q2].children} on columns,
[Gender].[Gender].ALLMEMBERS on rows

"""
res=s.getCatalog("FoodMart").query(cmd)
res.getSlice()The contained vs.wsdl originates from the following package: http://www.microsoft.com/en-us/download/confirmation.aspx?id=9388 and was subsequently modified (which parameters go in the soap header) to work with the zeep.
