Example

Below are examples of Teradata databases as follows. Below we have defined multiple examples of Teradata as follows.

• In the first example, we are connecting to the Teradata database as follows.

• In the below example, we have defined the number of AMP from the Teradata database as follows.

Select HASHAMP() + 1;

• In this example, we are creating the database in the Teradata database. We have created the database name as teradata_test.

CREATE DATABASE teradata_test from SYSDBA
AS
PERM = 1000000000,
SPOOL = 1000000000,
TEMPORARY = 10000000;

• In the below example, we are creating the table. Below we have created the table name as a test as follows.

CREATE SET TABLE TEST, FALLBACK (id INTEGER);

• In the below example, we are creating the table with the primary key. Below we have created the table name test1 as follows.

CREATE SET TABLE TEST1, FALLBACK (id INTEGER) UNIQUE PRIMARY INDEX (id);

Pre-requisites

To start with the Teradata tutorial, it is recommended to have an understanding of the below concepts as follows.

• Basic concept of database: Basic concepts of the database are also required to work with Teradata. We required a basic understanding of the concept of keys, relationships, indexes, and other database concepts.
• Programming languages: Knowledge of programming language is important while working with teradata. We have required knowledge of python and java.
• SQL Queries: We also required knowledge of SQL queries like select, update, delete, insert, join, and other SQL queries.
