错误提示是这样的：Presentations (unknown member) : Invalid request. The PowerPoint Frame window does not exist.转得还真有才...... 你要是可以教我，随便你怎么鄙视啊...
select top 12 * from Product where [id] not in (select top 12 [id] from Product) 这样可以分页，但是我在后面想加个条件 select top 12 * from Product where [id] not in (select top 12 [id] from Prod ......
