Sql server 2005 如何计算SQL Server 2005中存储过程的大小？

我被要求对特定数据库中使用的空间进行全面细分。 我知道我可以使用SQL Server 2005中的sys.dm_db_partition_stats来计算数据库中每个表使用了多少空间，但是有没有办法确定数据库中存储过程的单个大小和总大小？当然，除了打开每一个和数一数字符

与实际数据相比，存储过程使用的总空间可能不太大，但如果有数百个存储过程，总空间可能会增加。

比计算字符稍微好一点的方法是使用信息schema.routines。您可以对每个例程定义的长度求和，请注意，每个例程定义的最大长度为4000个字符，请参阅下面没有此限制的方法：

select Sum(Len(Routine_Definition)) from information_schema.routines where routine_type = 'PROCEDURE' 也可以返回每个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。数据库空间不足通常是由于不备份日志文件，然后使用dbcc shrinkfile或dbcc shrinkdatabase收缩日志文件

在Sql 2000中，下面是一个例程，它提供的长度不超过4000个字符的限制：

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

Dave_H的解决方案在information_schema.routines表中达到了4000个字符的限制

尝试这样做，首先生成一个包含存储过程全文的表，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

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definition列是NVARCHARMAX，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

最大值为4000个字符。我正在研究一种不同的方法，类似于我们使用的另一种例行程序。但是，是的，如果你因为存储过程而没有空间，那你就是做错了！美好的还为我提供了触发器、视图和标量函数的大小！
