Error extracting Description field in DAX Studio

This is the reason and the solution, in case anyone else has the same problem

https://github.com/DaxStudio/DaxStudio/issues/60

This behaviour is not specific to DAX Studio, you get the same syntax error running these queries from any other client tool. The DMVs actually use a query language called DMX which is almost SQL, but not quite.

And I believe that "ID" and "Name" are reserved words in DMX, so if you quote these column names with square brackets they should work fine.

eg.

select [ID], [Name] from $SYSTEM.TMSCHEMA_TABLES
select [ID], TableID, [Name], Expression, FormatString from $SYSTEM.TMSCHEMA_MEASURES

Select functions give the same error.  Was hoping to do the following or similar SQL construct.

select right( [Name], charindex('-',[Name])-1 ) from $SYSTEM.TMSCHEMA_PARTITIONS order by [Name]

to remove the appended unique identification string.
