如何从 SQL 服务器更改跟踪中获取所有已更改表的列表

Question

如何获取在给定版本之后有任何跟踪更改的所有表（已启用更改跟踪）的列表？

Answer 1

好吧，要获得所有启用了更改跟踪的 table 的列表，您可以执行类似

的查询

SELECT sys.tables.name FROM sys.change_tracking_tables 
JOIN sys.tables ON tables.object_id = change_tracking_tables.object_id

然后您可以根据需要为版本添加 where 条件。我相信这回答了你的问题。

此外，如果您想查看有关更改的一些信息，您可以使用更改table 函数运行查询，例如下面针对特定 table 的查询。

DECLARE @synchronization_version NVARCHAR(MAX),@last_synchronization_version NVARCHAR(MAX)
SET @synchronization_version = CHANGE_TRACKING_CURRENT_VERSION();
SELECT
CT.*
FROM
CHANGETABLE(CHANGES Sales.CreditCard, @last_synchronization_version) AS CT

更新

我更新了原始查询以执行查看并打印结果，您可以在执行查询之前查看 tables，因为每个人有超过 1000 tables您可能想删除一些评论。

SET NOCOUNT ON;
DECLARE @Views as TABLE (name nvarchar(200));

INSERT INTO @Views (name)
SELECT sys.tables.name FROM sys.change_tracking_tables 
JOIN sys.tables ON tables.object_id = change_tracking_tables.object_id


DECLARE @viewName   nvarchar(200) = (select top 1 name from @Views);
DECLARE @sql        nvarchar(max) = '';
DECLARE @union NVARCHAR(20)
DECLARE @sql1 NVARCHAR(max)

SET @sql1 = 'DECLARE @synchronization_version NVARCHAR(MAX),@last_synchronization_versionNVARCHAR(MAX)
SET @synchronization_version = CHANGE_TRACKING_CURRENT_VERSION();'
PRINT(@sql1)
WHILE(Exists(select 1 from @Views)) BEGIN
SET @union = '';
    SET @sql = '
SELECT
    CT.*
FROM
CHANGETABLE(CHANGES ' + @ViewName +', @last_synchronization_version) AS CT'
IF (SELECT COUNT(name) FROM @Views) > 2
BEGIN
SET @union = '  UNION'      
END 
Print (@sql+@union);
DELETE FROM @Views where name = @viewName;
SET @ViewName = (select top 1 name from @Views);
END;

Answer 2

这将return列出自上一个跟踪版本以来更改过的所有表：

set nocount on;

-- We want to check for changes since the previous version
--declare @prevTrackingVersion int = INSERT_YOUR_PREV_VERSION_HERE
-- Comment out this line if you know the previous version
declare @prevTrackingVersion int = CHANGE_TRACKING_CURRENT_VERSION() - 1

-- Get a list of table with change tracking enabled
declare @trackedTables as table (name nvarchar(1000));
insert into @trackedTables (name)
select sys.tables.name from sys.change_tracking_tables 
join sys.tables ON tables.object_id = change_tracking_tables.object_id

-- This will be the list of tables with changes
declare @changedTables as table (name nvarchar(1000));

-- For each table name in tracked tables
declare @tableName nvarchar(1000)
while exists(select top 1 * from @trackedTables)
begin
  -- Set the current table name
  set @tableName = (select top 1 name from @trackedTables order by name asc);

  -- Determine if the table has changed since the previous version
  declare @sql nvarchar(250)
  declare @retVal int 
  set @sql = 'select @retVal = count(*) from changetable(changes ' + @tableName + ', ' + cast(@prevTrackingVersion as varchar) + ') as changedTable'
  exec sp_executesql @sql, N'@retVal int output', @retVal output 
  if @retval > 0
  begin
    insert into @changedTables (name) select @tableName
  end

  -- Delete the current table name 
  delete from @trackedTables where name = @tableName;  
end

select * from @changedTables;
