如果你是一个数据库工作者,或者是一个代码编写者,你是否为填写那些字段烦恼呢?少还好说,如果达到几十个,你一定会被弄得昏头晕脑,一下就失去了编写代码的快乐。
好了,用以下的方法使你省略了填写字段的烦恼,一下子就能够达到编写代码的性高潮!实在是居家旅游,必备良药,胜过伟哥!
第一步,建立视图!
create VIEW Col AS
select
b.Name ColName,
b.ColID,
c.Name xColtype,
(select Name from systypes where xUserType = c.xType and xType = xUserType) ColType,/*convert user define type to system type*/
b.Length Sizes,
b.Prec Prec,
b.xScale Scale,
convert(bit,b.status&8) Nulls,
a.Name ObjectName,
a.Type ObjectType
from sysobjects A,syscolumns b,systypes c
where a.type in ('U','V','P') and a.Id=b.Id and b.Xusertype=c.Xusertype
第一步,建立存储过程!
CREATE PROCEDURE sysgetcol
@objectname Char(80)
AS
declare
@objecttype char(10)
select
@objecttype = objecttype
from COL
where objectname = @objectname
if @@ROWCOUNT = 0
begin
Print 'Internal Error(001):'
Print ' not found object :''' + Rtrim(@objectname) +'''!'
Return -1
end
select
colname,
colType types,
xColType,
sizes,
prec,
scale,
colid,
Nulls
Into #temp
from COL
where objectname = @objectname
order by colid
--PATINDEX('%pattern%', expression)
--Script object Structure
if @objecttype = 'U'
begin
select 'Create Table ' + Rtrim(@objectname) + ' ('
union all
select ' ' + Rtrim(colname) + ' ' + RTrim(xColType)+
Case xColType when 'Char' then '('+RTrim(Convert(Char(3),sizes))+')'

else ''
end +
case nulls when 0 then' Not Null' else '' end + ' ,'
from #temp
union all
select ')'
end
/*Building select statement*/
select 'CREATE VIEW view_' + RTrim(@objectname) + ' AS' + Char(10) + 'select '
union all
