SQL Server:表和/或数据库使用的8K页数

Question

我可以使用T-SQL向我显示表用于存储其行的8K页数吗？

另外,我可以看到数据库正在使用的8K页数吗？

Answer 1

尝试这样的事情:

-- Total # of pages, used_pages, and data_pages for a given heap/clustered index
SELECT 
    t.NAME AS TableName,
    p.rows AS RowCounts,
    SUM(a.total_pages) AS TotalPages, 
    SUM(a.used_pages) AS UsedPages, 
    (SUM(a.total_pages) - SUM(a.used_pages)) AS UnusedPages
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
WHERE 
    t.NAME NOT LIKE 'dt%' 
    AND t.is_ms_shipped = 0
    AND i.OBJECT_ID > 255 
GROUP BY 
    t.Name, p.Rows
ORDER BY 
    t.Name

这会显示表格使用的页面 - 已使用,未使用和总计.

对于整个数据库 - 只需总结每个表的页面并重复每个数据库.
