Primary key: To identify each record in a table, at least there must be one data field, which should be unique. That is corresponding data field of every record should be unique. It is called primary key. Primary key is used to identify the unique record from a collection of records. Table Creation: Creating table comes under Data Definition Language (DDL). The CREATE command is employed for establishing databases on our platform by constructing tables in an already existing database . The Syntax for creating table is as follows: CREATE TABLE TABLE_NAME ( Column1 datatype, Column2 datatype, … );

Program Plan Intro

Primary key:

To identify each record in a table, at least there must be one data field, which should be unique.

That is corresponding data field of every record should be unique.

It is called primary key.

Primary key is used to identify the unique record from a collection of records.

Table Creation:

Creating table comes under Data Definition Language (DDL).

The CREATE command is employed for establishing databases on our platform by constructing tables in an already existing database.

The Syntax for creating table is as follows:

CREATE TABLE TABLE_NAME (

Column1 datatype,

Column2 datatype,

…

);
