Question

我试图在Oracle中报告两个不同的事情。 Priority和Non-Priority。但是，Non-Priority语句还包括Priority语句中的计数。如何从Priority计数中减去Non-Priority计数？目前，结果是：

优先级： 3
非优先级： 84

但它应该是：

优先级： 3
非优先级： 81

您是否注意到1个查询中有2个类似的查询？总有一种更好的方法，通常是使用CASE语句。：）

另外，您使用表ITEMDATA两次。但你加入相同的价值，所以一旦足够。请始终使用表别名来使您的生活更轻松。你可能已经发现了这一点。

修改：用类似＆＃39;％xx％＆＃39;替换了instr（）。

,      case when it.itemname like '%ANES OP%' then 'prio'
            when it.itemname like '%TPN%' then 'prio'
            when it.itemname like '%CODE BLUE%' then 'prio'
            else 'non-prio'
   end prio_type
from   archivedqueue aq
join   scanninglog   sl on sl.batchnum = aq.batchnum
