2.表结构

 1 DECLARE @TableName varchar(20)

 2 SET @TableName='HR_Duty'

 3 SELECT

 4         (CASE when a.colorder=1 then d.name else '' end) AS 表名,

 5         a.colorder 字段序号,

 6         a.name 字段名,

 7         (case when COLUMNPROPERTY( a.id,a.name,'IsIdentity')=1 then '√'else '' end) 标识,

 8         (case when (SELECT count(*)

 9         FROM sysobjects

10         WHERE (name in

11                   (SELECT name

3.查进程及CPU占用时间,text为运行的Sql

 1 select db_name(database_id),session_id,cpu_time,start_time,command,database_id,[user_id],connection_id,[text]

 2 from sys.dm_exec_requests t1

 3 cross apply sys.dm_exec_sql_text(t1.sql_handle)

 4 --WHERE session_id=@@spid

 5 ORDER BY cpu_time desc

 6 --杀死相关进程

 7 SELECT @@spid

 8 --KILL 2529

 9 

10 --sELECT text FROM sys.dm_exec_requests as t1

11 --cross apply sys.dm_exec_sql_text(t1.sql_handle)

12 --,sys.dm_os_tasks t2,sys.dm_os_threads t3

13 --where t1.session_id=t2.session_id and t2.worker_address=t3.worker_address

14 --and  t3.os_thread_id=24564.查找对象依赖项--------------------------------------------------------------------------------

15 --查找对象依赖项

4.根据SQL存储过程名取得存储过程的内容

 1 --     GetContentByProcedureName '[dbo].[存储过程名]'

 2 --Create procedure GetContentByProcedureName

 3 --(@ProcedureName nvarchar(500))

 4 --as

 5 DECLARE @ProcedureName nvarchar(500)

 6 SELECT @ProcedureName='B_Add_Proc'

 7 if exists (select * from dbo.syscomments where id=object_id(N''+@ProcedureName+''))

 8     select c.text, c.encrypted, c.number,

 9     xtype=convert(nchar(2), o.xtype),    

10     datalength(c.text), convert(varbinary(8000),

11     c.text), 0 from dbo.syscomments c, dbo.sysobjects o   

12     where o.id = c.id and c.id = object_id(N''+@ProcedureName+'')

13     order by c.number, c.colid option(robust plan)
