WHERE clause is used to retrieve row-level data from the table, based on the condition.

For example.

Select * from employees where emp_salary>10000.

Here the employee is a table name.

emp_salary is a column name.

The answer displays the rows only which that have > than 10000.

Where Clause comes under selection.

In selection we can select rows only.

The SQL WHERE clause limits the row data that are returned. We limit column data only in the first select clause.

The where clause is used to check the condition.

Based on the condition, we can select some specific records from the table and we can update some specific records in the table, and also we can delete some specific records from the table.

Where clause specifies which records should be updated. E.g give me all the records of all the students who are 18 yrs. The WHERE clause is synonymous to"who are 18 yrs".

Can we write the syntax as:

select 'ename' from records where salary>260000;

Where records is table name and ename is employee name why not?

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.
