复制代码 代码如下: SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE function [dbo].[SplitString] ( @Input nvarchar(max), @Separator nvarchar(max)=',', @RemoveEmptyEntries bit=1 ) returns @TABLE table ( [Id] int identity(1,1),
复制代码 代码如下: SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE function [dbo].[SplitString] ( @Input nvarchar(max), @Separator nvarchar(max)=',', @RemoveEmptyEntries bit=1 ) returns @TABLE table ( [Id] int identity(1,1), [Value] nvarchar(max) ) as begin declare @Index int, @Entry nvarchar(max) set @Index = charindex(@Separator,@Input) while (@Index>0) begin set @Entry=ltrim(rtrim(substring(@Input, 1, @Index-1))) if (@RemoveEmptyEntries=0) or (@RemoveEmptyEntries=1 and @Entry<>'') begin insert into @TABLE([Value]) Values(@Entry) end set @Input = substring(@Input, @Index+datalength(@Separator)/2, len(@Input)) set @Index = charindex(@Separator, @Input) end set @Entry=ltrim(rtrim(@Input)) if (@RemoveEmptyEntries=0) or (@RemoveEmptyEntries=1 and @Entry<>'') begin insert into @TABLE([Value]) Values(@Entry) end return end 函数、表都建好了，下面调用测试一下吧： 复制代码 代码如下: declare @str1 varchar(max), @str2 varchar(max), @str3 varchar(max) set @str1 = '1,2,3' set @str2 = '1###2###3' set @str3 = '1###2###3###' select [Value] from [dbo].[SplitString](@str1, ',', 1) select [Value] from [dbo].[SplitString](@str2, '###', 1) select [Value] from [dbo].[SplitString](@str3, '###', 0) 结果，截个图来看一下：
