发帖数: 5177 | 3 Say I have two tables, Employee and PayRate. Employee has a primary key
EmpID which is a foreign key to PayRate. I need to update any matched
employees whose pay rate is greater than 1. I have to consider both
performance and mutual lock. Here are two solutions:
1. SELECT then UPDATE
select @cnt=count(*) from employee where name=@name and dob=@dob and empid
in (select empid from payrate where rate >1)
if @cnt > 1
begin
update employee set status = 1 where name=@name and dob=@dob and empid in

发帖数: 620 | 4 下面两句我没看出啥区别来, 谁说说??
(一个先判断一下, 然后update, 另一个直接update.)
if @cnt > 1
begin
update employee set status = 1 where name=@name and dob=@dob and empid in
(select empid from payrate where rate > 1)
2. UPDATE directly
update employee set status = 1 where name=@name and dob=@dob and empid in
(select empid from payrate where rate > 1) |

managers.
proc sql;
select lastname,firstname
from sasuser.staffmaster
where 'NA'=
(select jobcategory
from sasuser.supervisors
where staffmaster.empid = supervisors.empid);
我不明白的是 where clause里面的 'NA'= 是什么意思啊？作什么用的呢？为什么不写
成这样呢：
proc sql;
select lastname,firstname
from sasuser.staffmaster
where staffmaster.empid in
(select supervisors.empid
from sasuser.supervisors); |

Least Flycatcher听见唱歌没有？Empids我一般只能靠声音辨别，不过如果是Least的
话，这个eye ring好像不够宽。还有别的照片没有，换个角度看看嘴和primary
projection长短？

发帖数: 1745 | 15 真是过奖了。因为不打鸟，所以我在找鸟上经常偷懒。听见声音就算数，说实在的
Empids长什么样我没有怎么仔细研究过，大部分时间都花在找更好看的鸟上了 -_-|| 。
我对着Kaufman Field Guide to Advanced Birding好好看了一下。你打到的这只鸟从
背部颜色，喉咙和头部的反差，wingbar颜色和形状细节确实都和Least Flycatcher最
相近。Eye ring和primary projection(由于角度，不是特别容易判断)我还是不太拿得
准，不过我觉得这个很可能就是Least Flycatcher了。恭喜打到新鸟啊！ |

发帖数: 3103 | 16 哈哈，这本书我也有。我在这个鸟身上花了好几个钟头，这本书关于empid的那一章也
仔细看了很久，最后觉得有60-70%的把握吧（其它30-40%是Acadian Flycatcher），应
该差不多了。我的List只计拍到的、基本拿得准的，70%可以算是我的下限，已经极为
保守了。这个就先算了吧，已经老老实实地做好功课了。

发帖数: 1745 | 17 嗯，很像。
不好意思，Empids我没有仔细研究过，辨别基本靠耳朵。 |
