Answer 1

要查找启用了更改跟踪的表，请对跟踪的数据库执行以下脚本

SELECT s.name AS Schema_name, t.name AS Table_name 
FROM sys.change_tracking_tables ctt
JOIN sys.tables t 
    ON t.object_id = ctt.object_id
JOIN sys.schemas s
    ON s.schema_id = t.schema_id
ORDER BY s.name, t.name

您可以在此处找到有关更改跟踪的有用系统视图的更多详细信息：

sys.change_tracking_databases (Transact-SQL)

这是Brent Ozar的一个查询，它提供了一个由变更跟踪维护的隐藏表的列表，用于存储更改，CT中涉及的表格在这些隐藏表格中占用的行和空间。
