Purpose

Special predicate


Syntax

<expression> [NOT] IN (<value list>) <expression> [NOT] IN (<nested select>)


See Also

INSERT, PREDICATES, SELECT, UPDATE


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
