Choose three.

Which three statements are true about GLOBAL TEMPORARY TABLES?

A) A GLOBAL TEMPORARY TABLE cannot have PUBLIC SYNONYM.

B) A GLOBAL TEMPORARY TABLE can have multiple indexes

C) A GLOBAL TEMPORARY TABLE can be referenced in the defining query of a view.

D) Data Manipulation Language (DML) on GLOBAL TEMPORARY TABLES generates no REDO.

E) A GLOBAL TEMPORARY TABLE can have only one index.

F) A tigger can be created on a GLOBAL TEMPORARY TABLE

Answer：BCD

(解析：全局臨時表跟普通表同樣，能夠建立索引、視圖、觸發器等等，dml 操做一樣也會產生 redo。臨時表建立的目的就是爲了測試，若是不少操做不支持，那就失去了測試的意義。)
