例如:比如 産品字段protest有逗号組合,現在把這些分割開來。

變成如下:
方法如下:
create table dbo.test_name(
id int null
,name varchar(10) null
,protest varchar(500) null
);
insert into dbo.test_name values ('1','張三','電腦,電視機,掃地機');
insert into dbo.test_name values ('2','李四','掃地機');
insert into dbo.test_name values ('3','王五','');
insert into dbo.test_name values ('4','宋小','筆記本電腦,手機');
select a.id
,a.name
,a.protest
,SUBSTRING(a.protest,number,CHARINDEX(',',a.protest+',',number)-number) as protestxx
from test_name a with(nolock) ,master..spt_values with(nolock)
where type='p'
and SUBSTRING(','+a.protest,number,1)=','
如果查詢出剔除空的資料如下:
select a.id
,a.name
,a.protest
,SUBSTRING(a.protest,number,CHARINDEX(',',a.protest+',',number)-number) as protestxx
from test_name a with(nolock) ,master..spt_values with(nolock)
where number >= 1 and number < len(a.protest)
and type='p'
and SUBSTRING(','+a.protest,number,1)=','
