Raising your own errors in Yukon

Another thing I’ve noticed in Books Online – the new ERROR function, which allows you to raise your own errors. For example in AdventureWorks, try the following query:

WITH MEMBER MEASURES.TEST AS
IIF(MEASURES.[INTERNET ORDER COUNT]>2000
, MEASURES.[INTERNET ORDER COUNT]
, ERROR("TOO LOW!")
)
SELECT {MEASURES.[INTERNET ORDER COUNT], MEASURES.TEST} ON 0,
[DATE].[CALENDAR TIME].[ALL PERIODS].CHILDREN ON 1
FROM
[DIRECT SALES]

There’s a section in BOL on error handling which isn’t filled in yet so I guess this is probably only the tip of the iceberg as far as this area of functionality is concerned, but it’s interesting nonetheless.

One thought on “Raising your own errors in Yukon

  1. It isn\’t a tip of the iceberg – it is the entire iceberg in this area. I.e. you can put an MDX expression which returns a string inside Error function:Error("Product " + Product.CurrentMember.UniqueName + " has encountered an error in member property Weight")
