如何捕获在SQL中每天创建和删除的表的详细信息？

Question

需要找出每天创建和删除的表的列表。

Answer 1

首先，过时且不安全的方法。服务器级DDL触发器： link

我推荐的解决方案是使用SQL Server审核：

然后，您可以使用内置视图查看所有架构更改：

或者，以更灵活的方式，您可以查询最后一个日志文件，并根据需要应用任何过滤器：

 declare
 @database_name sysname =   N'my_database'
,@object_name   sysname =   N'my_object_name';

--  get last audit file path/name
declare @last_log_file  nvarchar(512)   =  (select [audit_file_path] from [sys].[dm_server_audit_status]);
declare @dt_from        datetime;
declare @dt_to          datetime;

--  transfer last log file into temporary table 
if object_id('tempdb..#auditlogs', 'u') is not null
begin
    drop table [#auditlogs];
end;


select * into [#auditlogs] from [sys].[fn_get_audit_file](@last_log_file, default, default);

--  get log file first/last rec dates
select 
     @dt_from   =   min([event_time])
    ,@dt_to     =   max([event_time])
from
    [#auditlogs];

--  index temporary table   
create nonclustered index [ix_#auditlogs__event_time]           on [#auditlogs]([event_time]        asc);
create nonclustered index [ix_#auditlogs__database_name]        on [#auditlogs]([database_name]     asc);
create nonclustered index [ix_#auditlogs__object_name]          on [#auditlogs]([object_name]       asc); 
create nonclustered index [ix_#auditlogs__audit_file_offset]    on [#auditlogs]([audit_file_offset] asc); 


--  display some info about the retrieved logs
select 
     [logs_from]        =   @dt_from    
    ,[logs_to]          =   @dt_to
    ,[log_file_name]    =   @last_log_file;

--  remove not actual data
delete from [#auditlogs] where 
        (nullif([database_name] , space(0)) is not null and [database_name] <> @database_name)
    or  (nullif([object_name]   , space(0)) is not null and [object_name]   <> @object_name);

Answer 2

 SELECT *
 FROM sys.tables
 WHERE create_date >= '20180712' AND create_date < '20180713' 

或者如果您想要一个特定的日期：

SELECT *
FROM sys.tables
WHERE cast(create_date AS DATE) = '2018-07-13'
