用于在存储过程中查找和替换文本的 SQL 查询

Question

如何查找和替换存储过程中的特定文本？

我有查找和替换查询，但我不确定如何将其发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

这是我能够想到的，它目前正在执行文本替换并重新创建存储过程。
