Cannot get DESCRIPTION from MDSCHEMA_MEASURES

HilaDG — Thu, 09 Mar 2023 02:59:38 GMT

I have a Power BI model which I'm trying to read the Metadata of.

Running the following query in DAX Studio works really well:

SELECT *
FROM $SYSTEM.MDSCHEMA_MEASURES
If I try to change it to list specific columns the way I want to, for example:

SELECT measure_cAption FROM $SYSTEM.MDSCHEMA_MEASURES

It works.

But not if I want DESCIPRION!

SELECT measure_cAption, DESCRIPTION
FROM $SYSTEM.MDSCHEMA_MEASURES
returns an error.

What am I missing? Or is this a bug? Images below

Many thanks!

@HilaDG Darren responded:

I believe the DESCRIPTION is a keyword in the Microsoft DMX language (which is what the DMV queries use)

If you enclose it in square brackets it should work SELECT [DESCRIPTION] FROM $SYSTEM.MDSCHEMA_MEASURES
