使用文中提供的代碼做一個統(tǒng)計表每天的新增行數(shù)及新增存儲空間的功能

實現(xiàn)步驟如下：

1. 創(chuàng)建表

創(chuàng)建表，存儲每天的表空間占用情況

				?

									CREATE TABLE [dbo].[t_rpt_table_spaceinfo](

									[table_name] [sysname] NOT NULL,

									[record_date] [date] NOT NULL,

									[record_time] [time](7) NOT NULL,

									[rows_count] [bigint] NULL,

									[reserved] [bigint] NULL,

									[data_size] [bigint] NULL,

									[index_size] [bigint] NULL,

									[unused] [bigint] NULL,

									CONSTRAINT [PK_t_rpt_table_spaceinfo] PRIMARY KEY CLUSTERED 

									(

									[table_name] ASC,

									[record_date] ASC,

									[record_time] ASC

									)

									)

2. 新建作業(yè)

新建作業(yè)，作業(yè)計劃每天凌晨運行一次，每天記錄表占用的空間情況，存儲到上一步建立的表中

作業(yè)中執(zhí)行的T-SQL代碼為：

				?

									SET NOCOUNT ON

									/*創(chuàng)建臨時表，存放用戶表的空間及數(shù)據(jù)行數(shù)信息*/

									CREATE TABLE #tablespaceinfo

									(

									nameinfo VARCHAR(500) ,

									rowsinfo BIGINT ,

									reserved VARCHAR(20) ,

									datainfo VARCHAR(20) ,

									index_size VARCHAR(20) ,

									unused VARCHAR(20)

									) 

									DECLARE @tablename VARCHAR(255); 

									/*使用游標(biāo)，循環(huán)得到表空間使用情況*/ 

									DECLARE Info_cursor CURSOR

									FOR

									SELECT '[' + [name] + ']'

									FROM sys.tables

									WHERE type = 'U'; 

									OPEN Info_cursor 

									FETCH NEXT FROM Info_cursor INTO @tablename 

									WHILE @@FETCH_STATUS = 0

									BEGIN

									INSERT INTO #tablespaceinfo

									EXEC sp_spaceused @tablename 

									FETCH NEXT FROM Info_cursor 

									INTO @tablename 

									END

									INSERT INTO t_rpt_table_spaceinfo

									(record_date, record_time, [table_name], [rows_count]

									, reserved, [data_size], index_size, unused)

									SELECT convert(date,getdate()), convert(varchar(8),getdate(),114), nameinfo, rowsinfo

									,CAST(REPLACE(reserved, 'KB', '') AS BIGINT) ,CAST(REPLACE(datainfo, 'KB', '') AS BIGINT) 

									,CAST(REPLACE(index_size, 'KB', '') AS BIGINT) ,CAST(REPLACE(unused, 'KB', '') AS BIGINT) 

									FROM #tablespaceinfo

									CLOSE Info_cursor 

									DEALLOCATE Info_cursor 

									DROP TABLE [#tablespaceinfo]

3. 查詢結(jié)果

連續(xù)的數(shù)據(jù)記錄之間做比較，即可得到數(shù)據(jù)的增量變化情況

示例代碼如下：

				?

									;with table_spaceinfo as

									(

									select record_date, record_time, table_name, rows_count, reserved, data_size, index_size, unused

									,ROW_NUMBER() over(PARTITION by table_name order by record_date,record_time asc) as list_no

									from t_rpt_table_spaceinfo

									)

									select _a.table_name as 表名,convert(varchar(20),_a.record_date)+' '+convert(varchar(8),_a.record_time)+'~~'

									+convert(varchar(20),_b.record_date)+' '+convert(varchar(8),_b.record_time) as [時間段范圍]

									,_b.rows_count-_a.rows_count as [新增的行數(shù)]

									,_b.data_size - _a.data_size as [新增數(shù)據(jù)空間(KB)]

									from table_spaceinfo _a

									join table_spaceinfo _b on _a.table_name=_b.table_name and _a.list_no=_b.list_no-1

									order by [時間段范圍]
