DMV Query -- all Catalogs and last processed time

Question

Hi 
I want to get a list of all catalogs & there last processed time, can you join the two DMV queries ?
SELECT * FROM $System.DBSCHEMA_CATALOGS
SELECT CUBE_NAME, LAST_DATA_UPDATE FROM $System.MDSCHEMA_CUBES

Answer 1

I just used the one query , I was trying to list out all the catalogs and illustrate in an excel pivot table, unfortunately the last processed date is not available in the DBSCHEMA_CATALOGS
c
In order to get the last processed date I would have to connect to each Catalog to retrieve the data making it useless for excel, as the Last processed date in only available in the $System.MDSCHEMA_CUBES
schema
SELECT CUBE_NAME, LAST_DATA_UPDATE FROM $System.MDSCHEMA_CUBES
Hi Carlo,
In your scenario, you list out the catalogs using the query below
SELECT * FROM $System.DBSCHEMA_CATALOGS
And get the last processed date using the query below.
SELECT CUBE_NAME, LAST_DATA_UPDATE FROM $System.MDSCHEMA_CUBES
Now what you want to know if we can use the Join function to join those two queries, right?
The query engine for DMVs is the Data Mining parser. The DMV query syntax is based on the SELECT (DMX) statement. Although DMV query syntax is based on a SQL SELECT statement, it does not support the full syntax of a SELECT statement. Notably, JOIN, GROUP
BY, LIKE, CAST, and CONVERT are not supported.
So your requirement cannot be achieve currently.
Thank you for your understanding.
