用于查找和替换存储过程中的文本的SQL查询

Question

如何在存储过程中查找和替换特定文本？

我有查找和替换查询但我不知道如何将其发布回存储过程或使用查询结果更新存储过程.

这是我用于查找和替换的查询:

SELECT
   REPLACE (object_definition(object_id('storedprocedure_1')), 'findstring', 'replacestring')

Answer 1

Declare @spnames CURSOR
Declare @spname nvarchar(max)
Declare @moddef nvarchar(max)
Set @spnames = CURSOR FOR
select distinct object_name(c.id) 
from syscomments c, sysobjects o 
where c.text like '%findtext%'
and c.id = o.id
and o.type = 'P'    
OPEN @spnames
FETCH NEXT
FROM @spnames into @spname
WHILE @@FETCH_STATUS = 0
BEGIN   
    Set @moddef =
    (SELECT
    Replace ((REPLACE(definition,'findtext','replacetext')),'ALTER','create')
    FROM sys.sql_modules a
    JOIN 
    (   select type, name,object_id
    from sys.objects b
    where type in (
    'p' -- procedures
    )
    and is_ms_shipped = 0
    )b
    ON a.object_id=b.object_id where b.name = @spname)              
    exec('drop procedure dbo.' + @spname)
    execute sp_executesql @moddef
    FETCH NEXT FROM @spnames into @spname
END

这就是我能够提出的,它目前正在替换文本并重新创建存储过程.
