Where clause is used to limit the row. If I want to display only those student name who achieve greater than 80 then we limit the row.

Where basically used to filter Records(Rows).

select * from emp where ename='smith';

So, Here we are putting Restriction on the rows only.

The WHERE clause is used to extract only those records that fulfill a specified criterion.

Eg: customers from the country "India", in the "Customers" table

SELECT * FROM Customers
WHERE Country='India';

Actually the WHERE clause is used to extract only those data's that fulfills a specified criterion. It is used on row operation. E.g:

SELECT column_name(s)
FROM table_name
WHERE column_name sal value

Where class is used to retrieve row data from the table.

Suppose we have a one emp table that contains some columns if we want get the information of empid 234 so we have to write,

SELECT * from emp where Empid=234.
