For some reason it was an easier job than usual. Do you think we need to add the following 2 items? - 9f133763961e280d8ba692bcad0b061b861e9138 this is an optimizer transform improvement. - a8a968a8212ee3ef7f22795c834b33d871fac262 this is an optimizer costing improvement. Both of them can generate a better plan on some cases. -- Best Regards Andy Fan
