Question

我需要分析我的数据库。我想获取所有表名，它们的记录数和这些表的实际数据大小。如您所知，记录计数有时可能较低，但表的实际大小可能非常高。

你有这样的剧本吗？

Answer 1

这对你有用吗？这是我使用的脚本：

 SELECT 
    S.name +'.'+ T.name as TableName, 
    Convert(varchar,Cast(SUM(P.rows) as Money),1) as [RowCount],
    Convert(varchar,Cast(SUM(a.total_pages) * 8 as Money),1) AS TotalSpaceKB, 
    Convert(varchar,Cast(SUM(a.used_pages) * 8 as Money),1) AS UsedSpaceKB, 
    (SUM(a.total_pages) - SUM(a.used_pages)) * 8 AS UnusedSpaceKB
FROM sys.tables T
INNER JOIN sys.partitions P ON P.OBJECT_ID = T.OBJECT_ID
INNER JOIN sys.schemas S ON T.schema_id = S.schema_id
INNER JOIN sys.allocation_units A ON p.partition_id = a.container_id
WHERE T.is_ms_shipped = 0 AND P.index_id IN (1,0)
GROUP BY S.name, T.name
ORDER BY SUM(P.rows) DESC

顺便说一句，我把这些计数都当作钱，所以我可以得到逗号。

使用CURSOR和临时表的另一种方法。

IF OBJECT_ID(N'tempdb..[#TableSizes]') IS NOT NULL
  DROP TABLE #TableSizes ;
GO

CREATE TABLE #TableSizes
  (
    TableName nvarchar(128)  
  , [RowCount] int
  , ReservedSpaceKB int
  , DataSpaceKB int
  , IndexSizeKB int
  , UnusedSpaceKB int
  ) ;
GO

DECLARE RecCountCursor CURSOR FOR 
    SELECT S.name+'.'+T.name AS TableName
    FROM Sys.tables T INNER JOIN sys.schemas S ON (S.schema_id = T.schema_id)
    WHERE S.principal_id = 1
    ORDER BY TableName

OPEN RecCountCursor ;
DECLARE @TableName nvarchar(128) ;  

FETCH RecCountCursor INTO @TableName ;
WHILE ( @@FETCH_STATUS = 0 )
BEGIN    
    CREATE TABLE #TempTableSizes
      (
        [TableName] nvarchar(128)  
      , [RowCount] char(11)   
      , [ReservedSpace] varchar(18)
      , [DataSpace] varchar(18)    
      , [IndexSize] varchar(18)    
      , [UnusedSpace] varchar(18)  
      ) ;

    INSERT INTO #TempTableSizes
            exec sp_spaceused @objname = @TableName;       
    UPDATE #TempTableSizes SET [TableName] = @TableName;
    INSERT INTO #TableSizes
        SELECT [TableName], [RowCount], 
            SUBSTRING([ReservedSpace], 1, CHARINDEX(' KB', [ReservedSpace])), 
            SUBSTRING([DataSpace], 1, CHARINDEX(' KB', [DataSpace])),
            SUBSTRING([IndexSize], 1, CHARINDEX(' KB', [IndexSize])),
            SUBSTRING([UnusedSpace], 1, CHARINDEX(' KB', [UnusedSpace]))
         FROM #TempTableSizes
    DROP TABLE #TempTableSizes; 

    FETCH RecCountCursor INTO @TableName ;   
  end

CLOSE RecCountCursor ;     
DEALLOCATE RecCountCursor ;


SELECT *
FROM    [#TableSizes]
ORDER BY [ReservedSpaceKB] DESC ;

DROP TABLE #TableSizes ;

使用：

SELECT @@servername;

IF EXISTS(SELECT name FROM tempdb.sys.tables WHERE name LIKE '#spaceUsed%')
    BEGIN
        DROP TABLE #spaceUsed;
    END;
CREATE TABLE #spaceUsed  (
name VARCHAR(255) ,
rows INT ,
reserved VARCHAR(50) ,
data VARCHAR(50) ,
index_size VARCHAR(50) ,
unused VARCHAR(50));

EXEC sp_msforeachtable
@command1 =' 
--
INSERT INTO #spaceUsed
exec sp_spaceused N''?'';
'
,@whereand = ' And Object_id In (Select Object_id From sys.objects
Where SCHEMA_NAME(Schema_ID) like ''%'')';

DECLARE
   @spaceUsedData TABLE  (
   name VARCHAR(255) ,
   rows INT ,
   reservedMB BIGINT NULL ,
   dataMB BIGINT NULL ,
   index_sizeMB BIGINT NULL ,
   unusedMB BIGINT NULL);

INSERT INTO @spaceUsedData (name , rows , reservedMB ,  dataMB ,index_sizeMB ,unusedMB)
SELECT                  name , rows ,
Convert ( BIGINT ,Ltrim(Rtrim(Replace(reserved ,'KB' ,'')) ))/1024 ,
Convert ( BIGINT ,Ltrim(Rtrim(Replace(data ,'KB' ,'')) ))/1024 ,
Convert ( BIGINT ,Ltrim(Rtrim(Replace(index_size ,'KB' ,'')) ))/1024 ,
Convert ( BIGINT ,Ltrim(Rtrim(Replace(unused ,'KB' ,'')) ))/1024
FROM #spaceUsed;

SELECT * , reservedMB+  dataMB+index_sizeMB+unusedMB AS TotalMB FROM @spaceUsedData
ORDER BY rows DESC;
