SQL Server DBA Monitor Database FileSize

2022-07-07

筆記 SQL Server 如何藉由設定作業排程，定時紀錄資料庫各資料表使用的資料列以及容量，精進 DBA 的管理工作，也藉由自動化更省力 😘

SQL Server Logo

說明

首先建立資料表

USE DBA
DROP TABLE IF EXISTS TableRows
CREATE Table TableRows(
	DatabaseName nvarchar(100),
	TableName nvarchar(100),
	RowCounts int,
	TotalSpaceMB int,
	UsedPaceMB int,
	UnUsedSpaceMB int,
	InsertDatetime datetime2
)

要定期執行的 Script，藉由 sp_MSforeachdb 來迭代向所有的資料庫取得資料表資訊，並且寫入 DBA 資料庫之中。

DECLARE @command varchar(4000)
SELECT @command = '
USE [?];
IF db_name()  not in ("tempdb")
  INSERT INTO DBA.dbo.TableRows
  SELECT
    db_name() AS DatabaseName,
    t.NAME AS TableName,
    --s.Name AS SchemaName,
    p.rows AS RowCounts,
    SUM(a.total_pages) * 8 /1024 AS TotalSpaceMB,
    SUM(a.used_pages) * 8 /1024 AS UsedSpaceMB,
    (SUM(a.total_pages) - SUM(a.used_pages)) * 8 /1024 AS UnusedSpaceMB,
    GetDate()
  FROM
    sys.tables t
  INNER JOIN
    sys.indexes i ON t.OBJECT_ID = i.object_id
  INNER JOIN
    sys.partitions p ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_id
  INNER JOIN
    sys.allocation_units a ON p.partition_id = a.container_id
  LEFT OUTER JOIN
    sys.schemas s ON t.schema_id = s.schema_id
  WHERE
    t.NAME NOT LIKE "dt%"
    AND t.is_ms_shipped = 0
    AND i.OBJECT_ID > 255
  GROUP BY
    t.Name, s.Name, p.Rows
  ORDER BY
    t.Name
ELSE
  SELECT NULL
'

EXEC sp_MSforeachdb @command

加入排程作業，頻率不用太高，每天一次即可。
