sql 用函数来分割字符串

set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go


-- =============================================
-- Description:    分割字符串
-- =============================================
CREATE function [dbo].[split]
(
  @SourceSql varchar(8000),
  @StrSeprate varchar(10)
)
returns @temp table(F1 varchar(400),sequence int)
as
begin
  declare @i int
    declare @sequence int
    set @sequence = 1;
   set @SourceSql=rtrim(ltrim(@SourceSql))
   set @i=charindex(@StrSeprate,@SourceSql)
   while @i>=1
   begin
     insert @temp values(left(@SourceSql,@i-1),@sequence)
     set @SourceSql=substring(@SourceSql,@i+1,len(@SourceSql)-@i)
     set @i=charindex(@StrSeprate,@SourceSql)
     set @sequence = @sequence+1
   end
   if @SourceSql<>''
     insert @temp values(@SourceSql,@sequence)
   return
end

上面是分割的函数，创建在函数里

使用方法

如下：

SELECT CONVERT(INT,F1) FROM dbo.split('1,2,3,4,5,6', ',')
