MS SQL 查詢資料庫中每個資料表之列數與資料表大小(容量)資訊,很有用

 

資料庫用久了 

特別是會放附件的資料表

要定時查看資料表大小

避免異常

 

在網上找到很有用的語法

特記

USE DatabaseName(要查的資料庫名稱)
Go

SELECT 
    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
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
