1^F推carlcarl:我剛才也在作實驗不過覺得他的schema好像沒那麼複雜XD11/05 06:21

2^F→carlcarl:IN subquery 這個我記得有看過建議是千萬不要這樣作11/05 06:23

3^F推carlcarl:我看他的好像是1:1的關係所以用10萬:10萬筆資料下去跑11/05 06:28

4^F→carlcarl:不過也才4.6秒不知道他的為什麼可以跑那麼久= =a11/05 06:28

12^F推carlcarl:嗯嗯如果是IN一般固定的值效能就比較沒問題了11/05 10:09

13^F→carlcarl:如果效能差的話用點反正規化OK吧~~11/05 10:10

14^F→carlcarl:我加上反正規化避開join 時間就從4.5加快到1.X秒了11/05 10:11
