如何将存储过程的文本存入SQL Server 2000中的单个记录？

Question

通过以下脚本,我得到了数据库中的所有存储过程:

SELECT sm.id, OBJECT_NAME(sm.id) AS object_name, sm.text
FROM syscomments AS sm
JOIN sysobjects AS so ON sm.id = so.id
WHERE (so.status >= 0) AND (so.xtype = 'P')

我希望每个存储过程获得一行.表syscomments中的文本字段是nvarchar 4000.因此,方法可以存储在多个寄存器中.问题是我存储了超过15000个字符的过程.

识别使用多个记录的SP

SELECT sm.id, COUNT(sm.colid) AS Cantidad
INTO #SPrepeated
FROM  syscomments AS sm INNER JOIN
      sysobjects AS so ON sm.id = so.id
WHERE (so.status >= 0) AND (so.xtype = 'P') AND (so.category = 0)
GROUP BY sm.id, so.name
HAVING   (COUNT(sm.colid) > 1)

SELECT sm.id, OBJECT_NAME(sm.id) AS object_name, sm.text
into #Tresult
FROM syscomments AS sm
JOIN sysobjects AS so ON sm.id = so.id
JOIN #SPrepeated as spr ON so.id = spr.id
WHERE (so.status >= 0) AND (so.xtype = 'P')

select * from #Tresult

drop table #Tresult
drop table #SPrepeated

在#TResult中,我拥有表中有多个记录的所有存储过程syscomments.考虑到结果可能超过8000个字符,如何将这些分组并连接成每个过程的单个记录？

我按照 @devio 的建议从应用程序中调用了 SELECT 语句，并且它运行得很好（文本字段没有被截断）。@LittleBobbyTables 建议的脚本是问题的解决方案，只需稍作修改，因为第一条记录连接了两次相同的字符串。

-- Gonzalo's original code --
SELECT sm.id, COUNT(sm.colid) AS Cantidad
INTO #SPrepeated
FROM  syscomments AS sm INNER JOIN
  sysobjects AS so ON sm.id = so.id
WHERE (so.status >= 0) AND (so.xtype = 'P') AND (so.category = 0)
GROUP BY sm.id, so.name
HAVING   (COUNT(sm.colid) > 1)

SELECT sm.id, sm.colid, OBJECT_NAME(sm.id) AS object_name, 
    cast(sm.text as ntext) as [text]
into #Tresult
FROM syscomments AS sm
JOIN sysobjects AS so ON sm.id = so.id
JOIN #SPrepeated as spr ON so.id = spr.id
WHERE (so.status >= 0) AND (so.xtype = 'P')
