正在使用哪些表更改跟踪

Question

我的备份失败：由于错误2601，未能将提交表刷新到dbid 12中的磁盘。请查看错误日志以获取更多信息。

我的数据库启用了更改跟踪。我如何确定哪些表具有启用？我看了50+，并找不到它的。 SQL 2008 R2

感谢

Answer 1

要查找已启用了更改跟踪的表，执行以下脚本对跟踪数据库

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 

您可以找到有关有用的系统的详细信息观点变更跟踪在这里：

sys.change_tracking_tables (Transact-SQL)

sys.change_tracking_databases (Transact-SQL)

这里的布伦特奥扎尔查询，让您通过更改跟踪维护，存储改变了隐藏的表的列表，涉及CT的表中的行和空间占用这些隐藏的表。

SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED; 
GO

    sct1.name AS CT_schema, 
    sot1.name AS CT_table, 
    ps1.row_count AS CT_rows,

    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
