为了满足需求自定义Split()在SQL中实现，代码很整洁，感兴趣的朋友可以参考下，或许对你学习sql语句有所帮助...

declare @Index int, @Entry nvarchar(max)
SET QUOTED_IDENTIFIER ON
@Input nvarchar(max),
set @Input = substring(@Input, @Index+datalength(@Separator)/2, len(@Input))

复制代码代码如下:

end

SQL里面用自定义Split()完成个性化需求

end
@RemoveEmptyEntries bit=1
[Id] int identity(1,1),
while (@Index>0)
函数、表都建好了，下面调用测试一下吧：
select [Value] from [dbo].[SplitString](@str3, '###', 0)
CREATE function [dbo].[SplitString]
)
insert into @TABLE([Value]) Values(@Entry)
SET ANSI_NULLS ON
set @Index = charindex(@Separator,@Input)
select [Value] from [dbo].[SplitString](@str1, ',', 1)

复制代码代码如下:

GO
[Value] nvarchar(max)
set @str3 = '1###2###3###'
begin
if (@RemoveEmptyEntries=0) or (@RemoveEmptyEntries=1 and @Entry<>'')

@Separator nvarchar(max)=',',
declare @str1 varchar(max), @str2 varchar(max), @str3 varchar(max)
begin

as
set @str1 = '1,2,3'

if (@RemoveEmptyEntries=0) or (@RemoveEmptyEntries=1 and @Entry<>'')
returns @TABLE table
set @Index = charindex(@Separator, @Input)
(
set @Entry=ltrim(rtrim(@Input))
select [Value] from [dbo].[SplitString](@str2, '###', 1)
insert into @TABLE([Value]) Values(@Entry)
结果，截个图来看一下：
begin
(
end
)
end
return
set @Entry=ltrim(rtrim(substring(@Input, 1, @Index-1)))
set @str2 = '1###2###3'
begin
