--TEST CASE FOR TEMP TABLE
--1. temp table's feature:
-- 1). Coordinator isolation
-- 2). Session isolation.
-- 3). Auto drop when session quit.
-- 4). Unlogged
-- 5). Other features are the same as ordinary table.
--2. temp table's SQL interface:
-- 1) Create
-- 2) Use
-- 3) Analyze
-- 4) Truncate
-- 5) Discard
-- 6) Alter
