Question

我正在尝试使用SQL Anywhere 11从数据库中获取每个表的表大小。

我刚发现sp_spaceused已被弃用

对此有任何帮助将不胜感激！：）

Answer 1

系统视图SYSTAB可能是一个很好的选择。它可以为您提供表中的行数，它可以为您提供表使用的页数。（在下面的示例中，我将页面数乘以DB的页面大小以获得总字节大小。）

SELECT
    count,                      -- number of rows in the table
    (table_page_count * DB_PROPERTY('PageSize')) tablesize  
                                -- total size, in bytes
FROM SYSTAB
WHERE table_name = 'mytable';   -- or whatever limitations you want on 
                                -- the scope of the query

希望这有帮助。

您可以在Sql Server上使用此脚本来查找数据库中最大的表和行计数

SELECT sc.name +'.'+ ta.name TableName
,SUM(pa.rows) RowCnt
FROM sys.tables ta
INNER JOIN sys.partitions pa
ON pa.OBJECT_ID = ta.OBJECT_ID
INNER JOIN sys.schemas sc
ON ta.schema_id = sc.schema_id
WHERE ta.is_ms_shipped = 0 AND pa.index_id IN (1,0)
GROUP BY sc.name,ta.name
ORDER BY SUM(pa.rows) DESC

补充 Dan K 的回答。

SELECT
table_name,
count,                      
cast((table_page_count * DB_PROPERTY('PageSize')) as int) as Bytes,
cast(Bytes/1024 as varchar) + ' KB' as KB,
cast(Bytes/1024/1024 as varchar) + ' MB' as MB
FROM SYSTAB
WHERE creator = 1 
order by Bytes desc
