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.
Insert values:
Inserting values comes under Data Manipulation Language (DML).
- The INSERT command in SQL is employed to add records to an existing table.
Syntax for inserting values into the table is as follows:
INSERT INTO TABLE_NAME VALUES('DATA 1', 'DATA 2');
