sql相關:檢視儲存過程和表結構
sql資料庫相關:
1,檢視儲存過程的內建函式:sp_helptext
eg:sp_helptext 儲存過程名
2,提供一個儲存過程用於檢視資料庫表的新結構tbinfo
create procedure [dbo].[tbInfo]
(
@tbName varchar(50)
)
as
select
表名=case when a.colorder=1 then d.name else '' end,
表說明=case when a.colorder=1 then isnull(f.value,'') else '' end,
欄位序號=a.colorder,
欄位名=a.name,
標識=case when COLUMNPROPERTY( a.id,a.name,'IsIdentity')=1 then '√'else '' end,
主鍵=case when exists(select 1 from sysobjects where xtype='PK' and name in (
select name from sysindexes where indid in(
select indid from sysindexkeys where id = a.id AND colid=a.colid
))) then '√' else '' end,
型別=b.name,
佔用位元組數=a.length,
長度=COLUMNPROPERTY(a.id,a.name,'PRECISION'),
小數位數=isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0),
允許空=case when a.isnullable=1 then '√'else '' end,
預設值=isnull(e.text,''),
欄位說明=isnull(g.[value],'')
from syscolumns a
left join systypes b on a.xtype=b.xusertype
inner join sysobjects d on a.id=d.id and d.xtype='U' and d.name<>'dtproperties'
left join syscomments e on a.cdefault=e.id
left join sys.extended_properties g on a.id=g.major_id AND a.colid = g.minor_id
left join sys.extended_properties f on d.id=f.major_id and f.minor_id=0
where
order by a.id,a.colorder
將這個儲存過程放在資料庫--可編輯區--儲存過程下,即可以使用!
