寻求有关构建SQL查询的帮助:
我有两张桌子:
表1 - 对象:
object_id name owner
1 Object1 Owner1
2 Object2 Owner2
3 Object3 Owner3
表2 - 对象属性(每个对象只有3个属性)
object_id property_name Property_value
1 color blue
1 shape circle
1 inhouse true
2 color red
2 shape rectangle
2 inhouse false
3 color green
3 shape rectangle
3 inhouse true
我想构建一个这样的视图:
name owner color shape inhouse
Object1 Owner1 blue circle true
Object2 Owner2 red rectangle false
Object3 Owner3 green rectangle true
