我需要一种方法让@listOfPageIds 被识别为数字列表而不是字符串.我试过强制转换,删除单引号......我真的不想在 sql 中做一个循环.
I need a way to have the @listOfPageIds be recognized as a list of numbers instead of strings. I have tried casting, removing the single quotes... I really don't want to do a loop in sql.
Declare @listOfPageIds varchar(50) ;
Set @listofPageIds = '2, 3, 4, 5, 6, 7, 14, 15';
select * from mytable p where p.PageId in( @listOfPageIds);
嗯,在生产服务器上我会写一些表值函数来拆分列表,但是如果你需要快速的临时查询,这个 xml 技巧可以工作>
Well on production server I'd write some table valued function for splitting lists, but if you need quick ad-hoc query, this xml trick could work
declare @listOfPageIds varchar(50), @data xml
declare @temp table(id int)
select @listofPageIds = '2, 3, 4, 5, 6, 7, 14, 15';
select @data = '<t>' + replace(@listofPageIds, ', ', '</t><t>') + '</t>'
insert into @temp
select
t.c.value('.', 'int') as id
from @data.nodes('t') as t(c)
select * from @temp
