Syntax
bitand::=
Text description of bitand
Purpose
BITAND computes an AND operation on the bits of argument1 and argument2, both of which must resolve to nonnegative integers, and returns an integer. This function is commonly used with the DECODE function, as illustrated in the example that follows.
Note:
This function does not determine the datatype of the value returned. Therefore, in SQL*Plus, you must specify BITAND in a wrapper, such as TO_NUMBER, which returns a datatype.

Examples
The following represents each order_status in the sample table oe.orders by individual bits. (The example specifies options that can total only 7, so rows with order_status greater than 7 are eliminated.)
SELECT order_id, customer_id,
DECODE(BITAND(order_status, 1), 1, 'Warehouse', 'PostOffice')
Location,
DECODE(BITAND(order_status, 2), 2, 'Ground', 'Air') Method,
DECODE(BITAND(order_status, 4), 4, 'Insured', 'Certified') Receipt
FROM orders
WHERE order_status < 8;
ORDER_ID CUSTOMER_ID LOCATION MET RECEIPT
