sql数据库相关:
1,查看存储过程的内置函数:sp_helptext
eg:sp_helptext 存储过程名
2,提供一个存储过程用于查看数据库表的新结构tbinfo
create procedure [dbo].[tbInfo]
(
@tbName varchar(50)
)
as
select
表名=case when a.colorder=1 then d.name else '' end,
表说明=case when a.colorder=1 then isnull(f.value,'') else '' end,
字段序号=a.colorder,
字段名=a.name,
标识=case when COLUMNPROPERTY( a.id,a.name,'IsIdentity')=1 then '√'else '' end,
主键=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,
类型=b.name,
占用字节数=a.length,
长度=COLUMNPROPERTY(a.id,a.name,'PRECISION'),
小数位数=isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0),
允许空=case when a.isnullable=1 then '√'else '' end,
默认值=isnull(e.text,''),
字段说明=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 d.name=@tbName --如果只查询指定表,加上此条件
order by a.id,a.colorder
将这个存储过程放在数据库--可编辑区--存储过程下,即可以使用!
eg:tbinfo 表名
