sqlserver查看庫中表的相關信息(表大小、行數、空間等)

一、查看庫中各表大小及行數等信息

SELECT 
    t.NAME AS TableName,
    s.Name AS SchemaName,
    p.rows AS RowCounts,
    SUM(a.total_pages) * 8 AS TotalSpaceKB, 
    CAST(ROUND(((SUM(a.total_pages) * 8) / 1024.00), 2) AS NUMERIC(36, 2)) AS TotalSpaceMB,
    SUM(a.used_pages) * 8 AS UsedSpaceKB, 
    CAST(ROUND(((SUM(a.used_pages) * 8) / 1024.00), 2) AS NUMERIC(36, 2)) AS UsedSpaceMB, 
    (SUM(a.total_pages) - SUM(a.used_pages)) * 8 AS UnusedSpaceKB,
    CAST(ROUND(((SUM(a.total_pages) - SUM(a.used_pages)) * 8) / 1024.00, 2) AS NUMERIC(36, 2)) AS UnusedSpaceMB
FROM 
    [OES].sys.tables t
INNER JOIN      
    [OES].sys.indexes i ON t.OBJECT_ID = i.object_id
INNER JOIN 
    [OES].sys.partitions p ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_id
INNER JOIN 
    [OES].sys.allocation_units a ON p.partition_id = a.container_id
LEFT OUTER JOIN 
    [OES].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;

二、查詢數據庫中所有的表名及對應行數

SELECT   a.name, b.rows
FROM      sys.sysobjects AS a INNER JOIN
                sys.sysindexes AS b ON a.id = b.id
WHERE   (a.type = 'u') AND (b.indid IN (0, 1))
ORDER BY b.rows DESC
