in_predicate



	Command in_predicatarithmetic_expression [NOT] IN (subquery) \| arithmetic_expression [NOT] IN (arithmetic_expression, ..., arithmetic_expression)

Description

An in_predicate is used to compare an arithmetic_expression to check whether it is included (or NOT included if this keyword is also passed) in a list of values. The list of values used for the comparison can either be a sequence of arithmetic expressions that are passed or the result of a subquery.

Example

This example selects the records of the ORDERS table whose order_id column value is equal to 10000, 10001, 10003 or 10005:

SELECT *
FROM ORDERS
WHERE order_id IN (10000, 10001, 10003, 10005);
