SQL Server 2008：我有1000个表，我需要知道哪些表有数据

Question

SMSS中是否有办法检测表是否有任何记录？我需要获取有记录的表列表。也许有一个sql语句可以解决这个问题吗？

Answer 1

试试这个 - 给你表名和行数：

SELECT 
    t.NAME AS TableName,
    SUM(p.rows) AS [RowCount]
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
WHERE   
    i.index_id <= 1
GROUP BY 
    t.NAME, i.object_id, i.index_id, i.name 
ORDER BY 
    SUM(p.rows) DESC

它在单个输出中显示所有表及其行数。

由于您的问题特别提及SSMS，您也可以右键单击对象资源管理器中的数据库，然后从快捷菜单中执行

Reports -> Standard Reports -> Disc Usage By Table

Answer 3

更简单的语法：

SELECT  [Name]      = o.name
    ,     [RowCount]  = SUM(p.row_count)

FROM    SYS.DM_DB_PARTITION_STATS p

INNER JOIN
        SYS.TABLES o
    ON p.[object_ID] = o.[object_id]

WHERE   index_id    <= 1 -- Heap or clustered index only

GROUP BY o.name

ORDER   BY 2 desc

Answer 4

您可以使用此存储过程：

EXEC sp_MSforeachtable @command1="EXEC sp_spaceused '?'"

这将返回数据库中每个表的结果集（每个表都显示名称，行数以及其他信息）。

以下是如何将它们放入表变量中，并按行数排序：

DECLARE @TBL TABLE (
    [name] nvarchar(500),
    [rows] bigint,
    [reserved] nvarchar(500),
    [data] nvarchar(500),
    [index_size] nvarchar(500),
    [unused] nvarchar(500)
)

INSERT INTO @TBL
EXEC sp_MSforeachtable @command1="EXEC sp_spaceused '?'"

SELECT * FROM @TBL
ORDER BY [rows] DESC

Answer 5

希望，它可以帮助您-

SELECT name AS [TableList] FROM SYS.DM_DB_PARTITION_STATS s 
INNER JOIN sys.tables t ON t.[object_id] = s.[object_id]
WHERE row_count = 0

此代码显示该表列表，其中不包含任何数据或行。

谢谢！
