Answer / ravi
We know that in Teradata all the tables are either SET or MULTISET.
The difference between SET and MULTISET tables is –
SET tables – SET tables did not allow duplicate values in the table.
MULTISET tables – MULTISET tables allow duplicate values in table.
Many of us already defined the temporary tables and permanent table .
Type of Temporary Table :
1) Global temporary Table : GTT can be either SET or Multiset .
2) Volatile Table : It can be either SET or Multiset .
3) Derived Table : they are specified on a query level with an AS keyword in
an sql ststment.
Permanent Table : Permanent Table DDL as well as data stored in Permanent Space . It can be either Set or Multiset .

Answer / ram
Permanent Tables:
1. SET table - Strictly NO duplicate values [By-Default]
2. MULTI SET table - Allows Duplicate Values.
Temporary Tables:
1. Global Temporary Table - supports [Compression in table],
when session logged out, Table persists and its record gets
vanished.
2. Volatile Table - When session logged out, TABLE and its
records are not available further.

Answer / maruthi
create insert drop delete
sys sys sys sys-------------derived table
user user sys sys-------------volatile table
user user user sys--------------global temp table
user user user user-------------normal table
-->derived table will be created by system while executing sub queries
-->global temp table & volatile table has to be created by user by mentioning "global temporary table" , "volatile table" respectively in the syntax at the time of creating the table.
