Question

我被要求对特定数据库中使用的空间进行全面细分。我知道我可以在SQL Server 2005中使用 sys.dm_db_partition_stats 来计算数据库中每个表的空间大小，但有没有办法确定个人和数据库中存储过程的总大小？（当然，没有打开每一个并计算字符。）

存储过程使用的总空间不太可能很大（与实际的数据相比），但有数百个，它可能会累加。

Answer 1

;WITH ROUTINES AS (
    -- CANNOT use INFORMATION_SCHEMA.ROUTINES because of 4000 character limit
    SELECT o.type_desc AS ROUTINE_TYPE
            ,o.[name] AS ROUTINE_NAME
            ,m.definition AS ROUTINE_DEFINITION
    FROM sys.sql_modules AS m
    INNER JOIN sys.objects AS o
        ON m.object_id = o.object_id
)
SELECT SUM(LEN(ROUTINE_DEFINITION))
FROM ROUTINES

Answer 2

比计算字符稍微好一点的方法是使用信息schema.routines。您可以将每个例程定义的长度相加为（注意每个例程定义最多为4,000个字符，请参阅下面的没有此限制的方法）：

select Sum(Len(Routine_Definition)) from information_schema.routines 
where routine_type = 'PROCEDURE'

或者你可以返回每个sp的长度

select Len(Routine_Definition), * from information_schema.routines 
where routine_type = 'PROCEDURE'

存储过程的长度不太可能是问题所在。通常用数据库耗尽空间是因为没有备份日志文件（然后使用dbcc shrinkfile或dbcc shrinkdatabase缩小它）。

在Sql 2000中，这是一个例程，它提供的长度没有上面的4000个字符限制：

DECLARE @Name VarChar(250)
DECLARE RoutineCursor CURSOR FOR
   select Routine_Name from information_schema.routines where routine_type = 'PROCEDURE'

DECLARE @Results TABLE
   (   SpName   VarChar(250),
       SpLength   Int
   )

CREATE TABLE ##SpText
   (   SpText   VarChar(8000)   )

OPEN RoutineCursor
FETCH NEXT FROM RoutineCursor INTO @Name

WHILE @@FETCH_STATUS = 0
   BEGIN
      INSERT INTO ##SpText   (SpText)   EXEC sp_helptext @Name

      INSERT INTO @Results (SpName, SpLength) (SELECT @Name, Sum(Len(SpText)) FROM ##SpText)
      TRUNCATE TABLE ##SpText

      FETCH NEXT FROM RoutineCursor INTO @Name
   END

CLOSE RoutineCursor
DEALLOCATE RoutineCursor
DROP TABLE ##SpText

SELECT SpName, SpLength FROM @Results ORDER BY SpLength DESC
SELECT Sum(SpLength) FROM @Results

Answer 3

Dave_H的解决方案在information_schema.routines表中达到了4,000个字符的限制

试试这个，首先生成一个带有sprocs全文的表，然后对字符长度求和。

--create a temp table to hold the data
create table ##sptext (sptext varchar(1000))
go

--generate the code to insert the full text of your sprocs
select 'insert into ##sptext (sptext) exec sp_helptext '''+specific_name+''';'
from information_schema.routines 
where routine_type = 'PROCEDURE'
go

/*Copy the output back to your query analyzer and run it*/

--now sum the results    
select sum(len(sptext))
from ##sptext

Answer 4

需要使用DATALENGTH而不是LEN来获取字节数而不是字符数，因为sys.sql_modules目录视图的定义列是NVARCHAR（MAX），即Unicode

SELECT Type,
   SUM(Chars)  SizeChars,
   SUM(Bytes)  SizeBytes,
   SUM(Bytes) / 1024. SizeKB,
   CAST(SUM(Bytes) / 1024 AS VARCHAR) + '.' + CAST(SUM(Bytes) % 1024 AS VARCHAR) SizeKBRemBytes
FROM
(
SELECT o.type_desc Type, 
       LEN(sm.definition) Chars,
       DATALENGTH(sm.definition) Bytes
    FROM sys.sql_modules sm
    JOIN sys.objects o ON sm.object_id = o.object_id
) x
GROUP BY Type
ORDER BY Type
