Description
IN is a special predicate to evaluate whether the specified <expression> is equal to one of the values in the <value list> or <nested select>. The <value list> contains a list of comma separated values. The <nested select> is an SQL SELECT clause.
The optional NOT evaluates whether the specified <expression> is not equal to any of the values in the <value list> or <nested select>.
The data type must be the same for the <expression> and all the values in <value list> or returned by the <nested select>.
Example
SELECT name, address, balance, cost*1.15; FROM accounts; WHERE paid_date < date() AND ord_value IN (100, 200, 300); ORDER BY name, paid_date SELECT name, address, balance, rep_id; FROM accounts; WHERE rep_id IN (SELECT emp_id from employees where location = 'MA'); ORDER BY name
