分割再成批插入
declare @s varchar(8000),@sql nvarchar(4000)
set @s='1,12,1212,4545'
set @sql='insert into t(col) select '+replace(@s,',',' col union all select ')
exec(@sql)
测试
drop table #table
declare @s varchar(8000),@sql nvarchar(4000)

create table #table (col int)

exec(@sql)
select * from #table
create function f_split(@SourceSql varchar(8000),@StrSeprate varchar(10))
returns @temp table(a varchar(100))
--实现split功能 的函数
as
begin
declare @i int
set @SourceSql=rtrim(ltrim(@SourceSql))
set @i=charindex(@StrSeprate,@SourceSql)

end
用法:select * from dbo.f_split('ABC:BC:C:D:E',':')
、Get_StrArrayLength
CREATE function Get_StrArrayLength
(
@str varchar(1024), --要分割的字符串
@split varchar(10) --分隔符号
)
returns int
as
begin
declare @location int
declare @start int
declare @length int
set @str=ltrim(rtrim(@str))
set @location=charindex(@split,@str)
set @length=1
while @location<>0
begin
set @start=@location+1
set @location=charindex(@split,@str,@start)
set @length=@length+1
end
return @length
end
2、Get_StrArrayStrOfIndex
CREATE function Get_StrArrayStrOfIndex
(
@str varchar(1024), --要分割的字符串
@split varchar(10), --分隔符号
@index int --取第几个元素
)
returns varchar(1024)

begin
set @start=@location+@seed
set @location=charindex(@split,@str,@start)
set @next=@next+1
end
if @location =0 select @location =len(@str)+1
--这儿存在两种情况:1、字符串不存在分隔符号 2、字符串中存在分隔符号,跳出while循环后,@location为0,那默认为字符串后边有一个分隔符号。
return substring(@str,@start,@location-@start)
end
3、应用:
set @next=1
while @next<=dbo.Get_StrArrayLength(@KeyWords,',')
begin

set @s='1,12,1212,4545'
set @sql='insert into t(col) select '+replace(@s,',',' col union all select ')
exec(@sql)
