SQL 查询所有表名、字段名、类型、长度、存储过程、视图

-- 获得存储过程创建语句
select o.xtype,o.name,cm.text from syscomments cm
inner join sysobjects o on o.id=cm.id
where xtype =‘p‘
order by o.xtype,o.name,cm.text

-- 获得视图程创建语句
select o.xtype,o.name,cm.text from syscomments cm
inner join sysobjects o on o.id=cm.id
where xtype =‘v‘
order by o.xtype,o.name,cm.text

-- 查询所有表名、字段名、类型、长度
select o.name, c.name,t.name,c.length from syscolumns c
inner join systypes t on c.xtype= t.xtype
inner join sysobjects o on c.id= o.id
where   o.xtype=‘u‘
order by  o.name, c.name,t.name

-- 所有数据都来自于这四张表
--select * from sysobjects
--select * from syscolumns
--select * from syscomments
--select * from systypes
