How to get a list of the Tables maintained by Change Tracking in SQL

Thanks to Brent Ozar and Dave Phillips who showed us how to get a list of the Tables maintained by Change Tracking directly in MS SQL Server Management Studio. It works for both AX2012 and D365 versions.


SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED;
GO
SELECT
   sct1.name AS CT_schema,
   sot1.name AS CT_table,
   ps1.row_count AS CT_rows,
   ps1.reserved_page_count*8./1024. AS CT_reserved_MB,
   sct2.name AS tracked_schema,
   sot2.name AS tracked_name,
   ps2.row_count AS tracked_rows,
   ps2.reserved_page_count*8./1024. AS tracked_base_table_MB,
   change_tracking_min_valid_version(sot2.object_id) AS min_valid_version
FROM sys.internal_tables it
JOIN sys.objects sot1 ON it.object_id=sot1.object_id
JOIN sys.schemas AS sct1 ON sot1.schema_id=sct1.schema_id
JOIN sys.dm_db_partition_stats ps1 ON it.object_id = ps1. object_id AND ps1.index_id in (0,1)
LEFT JOIN sys.objects sot2 ON it.parent_object_id=sot2.object_id
LEFT JOIN sys.schemas AS sct2 ON sot2.schema_id=sct2.schema_id
LEFT JOIN sys.dm_db_partition_stats ps2 ON sot2.object_id = ps2. object_id AND ps2.index_id in (0,1)
WHERE it.internal_type IN (209, 210)
order by tracked_name
;

GO
