一些比较难的sql问题:1(三)

5、字符串检索问题
表
ID IndexArr
1 1,2,3,4,5
2 55,6,99,87,1000
3 7,567567,567,43,123
IndexArr 是","分割的数字
现在有字符串 '2,34,45,345,867,4,984'
现在要检索的是 IndexArr 中每一个数字都在 字符串中出现过的 结果集。
我的解法:
[sql]
--1.函数
if exists(select * from sys.objects where name = 'f_splitSTR' and type = 'tf')
drop function dbo.f_splitSTR
go
create function dbo.f_splitSTR
(
@s varchar(8000), --要分拆的字符串
@split varchar(10) --分隔字符
)
returns @re table( --要返回的临时表
col varchar(1000) --临时表中的列
)
as
begin
declare @len int
set @len = LEN(@split) --分隔符不一定就是一个字符,可能是2个字符
while CHARINDEX(@split,@s) >0
begin
insert into @re
values(left(@s,charindex(@split,@s) - 1))
set @s = STUFF(@s,1,charindex(@split,@s) - 1 + @len ,'') --覆盖:字符串以及分隔符
end
insert into @re values(@s)
return --返回临时表
end
go
--> 测试数据:[tb]
if object_id('[tb]') is not null
drop table [tb]
go
create table [tb]([ID] int,[IndexArr] varchar(19))
insert [tb]
select 1,'1,2,3,4,5' uni
