程序|存储过程|数据|数据库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))+')'
when 'Numeric' then '(' + RTrim(Convert(Char(3),Prec)) + ',' + RTrim(Convert(Char(3),Scale)) + ')'
when 'Varchar' then '('+RTrim(Convert(Char(3),sizes))+') '
when 'nchar' then '(' + RTrim(Convert(Char(3) ,sizes)) + ')'
when 'nvarchar' 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
select ' '+RTrim(colname)+',' from #temp --order by colid
union all
select 'from '+ RTrim(objectname)

/******update #temp set sizes=Null where Types<>'Char'******/
--bulid procedure parameter
select 'CREATE PROCEDURE ' + RTrim(objectname) + '_Update'
UNION ALL
select
' ' + RTrim(colname) + ' ' + RTrim(xColType)+
Case xColType when 'Char' then '('+RTrim(Convert(Char(3),sizes))+') ,'
when 'Numeric' then '(' + RTrim(Convert(Char(3),Prec)) + ',' + RTrim(Convert(Char(3),Scale)) + ') ,'
when 'Varchar' then '('+RTrim(Convert(Char(3),sizes))+') ,'
when 'nchar' then '(' + RTrim(Convert(Char(3) ,sizes)) + ')'
when 'nvarchar' then '(' + RTrim(Convert(Char(3) ,sizes)) + ')'
else ' ,'
end
from #temp
--order by colid
UNION ALL
select 'AS'
/*Building update part*/
UNION ALL
select ' update ' + RTrim(objectname) + ' set'
UNION ALL
select ' '+RTrim(colname)+' = '+RTrim(colname)+' ,' from #temp-- order by colid
Union All
select ' where '
Union All
select ' '+RTrim(colname)+' = '+RTrim(colname)+' and' from #temp-- order by colid
UNION ALL
/*update #temp set sizes=Null*/

/*Building Insert statement*/
select ' if ROWCOUNT = 0'
UNION ALL
select ' insert into ' + Rtrim(objectname) + '('
UNION ALL
select ' '+RTrim(colname)+' ,' from #temp-- order by colid
UNION ALL
select ' )'
UNION ALL
select ' values('
UNION ALL
select ' '+RTrim(colname)+' ,' from #temp --order by colid
UNION ALL
select ' )'

select ' '+RTrim(colname)+' = Trim(request("'+RTrim(colname)+'"))' from #temp

select ' '+RTrim(colname)+' = Trim(rs("'+RTrim(colname)+'"))' from #temp --order by colid

select ' .parameters('+Rtrim(colid)+') = '+ colname from #temp --order by colid
GO


第三步，使用该存储过程！
假设你的数据库里有一个叫做Nta_base_member的表
Create Table Nta_base_member (
m_id bigint Not Null ,
m_type smallint ,
m_state smallint ,
memberid bigint ,
travelco_id bigint
)

打开你的查询分析器，键入
sysgetcol Nta_base_member

然后按ctrl+t，然后按F5，看看查询分析器出现什么东东？
