[問題] database view跟table的問題
<<<Database>>>
create view時
是用table來create的
那請問可以用幾個view來create新的一個view嗎？
就像：
create view viewNEW as select
viewAAA.entity_id, viewAAA.time_id, viewAAA.value as viewAAA,
viewBBB.entity_id, viewBBB.time_id, viewBBB.value as viewBBB,
viewCCC.entity_id,viewCCC.time_id,viewCCC.value as viewCCC,
from viewBBB, viewAAA, viewCCC
where viewAAA.entity_id = viewCCC.entity_id,
viewCCC.entity_id = viewBBB.entity_id
