这里设定传过来的参数是拼接好的字符串,如:1,2,3,4,5 create procedure up_batchDeleteById ( @condition varchar(max) ) as delete from dt_name where id in(@condition) 以上的做法看似正确,实际会报错,具体原因是说id是int类型的,而@condition是字
这里设定传过来的参数是拼接好的字符串,如:1,2,3,4,5
create procedure up_batchDeleteById
(
@condition varchar(max)
)
as
delete from dt_name where id in(@condition)
以上的做法看似正确,实际会报错,具体原因是说id是int类型的,而@condition是字符串类型,这样无法删除
正确做法:
create procedure up_batchDeleteById
(
@condition varchar(max)
)
as
declare @sql varchar(max)
set @sql='delete from dt_name where id in (' + @condition + ')'
exec(@sql)
