sp_MSforeachdb is indeed a cursor, and not a particularly good one.

Still, it exists, and it's useful for quick-and-dirty tasks sometimes, particularly if you don't have a lot of dbs.

So, I'll offer a version for it:

CREATE TABLE #t_nodb (

dbname nvarchar(128)

)

EXEC sp_MSforeachdb '

IF ''?'' IN (''tempDB'') -- IN (''master'', ''model'', ''msdb'', ''tempdb'')

RETURN

INSERT INTO #t_nodb

SELECT ''?''

WHERE

NOT EXISTS(SELECT 1 FROM [?].sys.extended_properties)

'

SELECT *

FROM #t_nodb

ORDER BY dbname

DROP TABLE #t_nodb
