拼接字符串转化为table并作为查询条件

DECLARE @DATAAREAID AS NVARCHAR(MAX)
set @DATAAREAID='001,002,003,004'
if object_id('tempdb..##MyTempTable1') is not null
	Begin
		DROP TABLE ##MyTempTable1  --如果有存在就删除临时表
	End
	Select * Into ##MyTempTable1 From 
	(
		SELECT B.id,B.typeid  
		FROM   (  
					SELECT [value] = CONVERT(XML, '<v>' + REPLACE(@DATAAREAID,',', '</v><v>') + '</v>')  
				) A  
				OUTER APPLY(  
			SELECT id = N.v.value('.', 'nvarchar(100)'),typeid=1
			FROM   A.[value].nodes('/v') N(v)  
		) B  
	) as T

select  PRICECALCID,Price,DATAAREAID,MisItemName into ##tmp2 
from A
where DATAAREAID in (select id from ##MyTempTable1 where typeid=1)
