What are the types of tables in Teradata

Answer Posted / 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 .
