关于存储过程的函数

来源：互联网发布：http请求格式 json 编辑：程序博客网时间：2024/06/06 00:56

--1、查看所有存储过程与函数
     exec sp_stored_procedures
    或者
     select * from dbo.sysobjects where OBJECTPROPERTY(id, N'IsProcedure') = 1 order by name
--2、查看存储过程的内容
   select text from syscomments where id=object_id('存储过程名称')
   -- 或者用
   sp_helptext 存储过程名称

--3、查看存储过程的参数情况
   select '参数名称' = name,
         '类型' = type_name(xusertype),
         '长度' = length,
         '参数顺序' = colid,
         '排序方式' = collation
   from    syscolumns
   where   id=object_id('存储过程名称')

--或者

   --查看存储过程参数信息：
--如果返回值>1，则有参数。否则无
CREATE   PROC sp_PROC_Params
       @procedure_name sysname , --存储过程或者用户定义函数名
       @group_number int=1     ,   --存储过程的组号,必须在0到32767之间,0表示显示该存储过程组的所有参数
       @operator nchar(2)=N'='     --查找对象的运算符
AS
SET   NOCOUNT ON
DECLARE @SQL nvarchar(4000)
SET @SQL=N'SELECT

--4、查看所有存储过程内容
select b.name ,a.text from syscomments a,sysobjects b where object_id(b.name)=a.id and b.xtype in('P','TR')

--5、查看包含字符串内容的存储过程

select   b.name   ,a.text   from   syscomments   a,sysobjects   b
where
charindex('字符串内容',a.text)>0    and
object_id(b.name)=a.id   and   b.xtype   in('P','TR')
