很久以前無聊寫的東西, 以SQL Command查詢DB中的table有哪些, 儲存到Table中,
查詢以多少個Table, 和資料筆數, 做成StoreProcedure, 再定期將資料儲存起來.
可以將這些結果查詢Table中的資料成長數量.
(使用在MS SQL Server 2008-R2, 其它DB的語法會有些與不同唷)

如前言.
不多說, 直接上Code吧.

第一段, 建立 DATABASE [Administration]
和 DB_Control, DB_Record, DB_FileUseSize
三個Table的用途等等就會知道囉,

(這邊做了一個錯誤示範, 我懶得改了, Column建議不要用關鍵字命名.
那時候居然用 Roe取Column的名字 XDDD)

第二段取得各DB 名稱, 和檔案的大小, 寫入剛剛建立的Table [DB_FileUseSize] 中.

WHILE @rowNo <= @max  
    BEGIN 
        --此處對每一行要進行的操作的代碼   
                select @DbSerId=DbSerId,@dbname=dbname from #depTemp WHERE DbSerId=@rowNo
                --取得DB為@dbname
                --DB編號  @DbSerId
--print @DbSerId
--print @dbname

--清除掉暫存的table
IF OBJECT_ID(''tempdb..#Data'') IS NOT NULL 
    DROP TABLE #Data
IF OBJECT_ID(''tempdb..#DataNew'') IS NOT NULL 
    DROP TABLE #DataNew

insert into #TableRelate exec sp_tables
 
declare @name varchar(255) 
declare @tableCount varchar(100) 
--用cur來當取得所有的db name
declare cur cursor  for

--字串要拼好 [dbo].[DB_Name]

select convert(int,'''+convert(nvarchar(255),@DbSerId)+''') as DbSerID,

    DROP TABLE #Data

DECLARE @dbCount INT

DROP TABLE #depTemp--清除臨時表
IF OBJECT_ID('tempdb..#Data') IS NOT NULL 
    DROP TABLE #Data
IF OBJECT_ID('tempdb..#DataNew') IS NOT NULL 
    DROP TABLE #DataNew

第三段, 直接把剛剛儲存的結果查詢出來吧.

use Administration

select * 
from dbo.DB_Control 
left JOIN DB_Record on DB_Control.DbSerid = DB_Record.DbSerid
LEFT JOIN DB_FileUseSize on DB_Control.DbName = DB_FileUseSize.DbName


select * from dbo.DB_LogFile

可以看到各DB和Table的資料了.
