A WHERE clause in SQL is a data manipulation language statement.
WHERE clauses are not mandatory clauses of SQL DML statements. But it can be used to limit the number of rows affected by a SQL DML statement or returned by a query.
Actually. it filters the records. It returns only those queries which fulfill the specific conditions.
WHERE clause is used in SELECT, UPDATE, DELETE statement etc.
Let’s see the syntax for sql where:
SELECT column1, column 2, … column n
WHERE clause uses some conditional selection

< less than
>= greater than or equal
<= less than or equal
< > not equal to44
