bitwise.or
Description
Performs a bitwise OR operation on two integers. Each bit in the result is 1 if at least one of the corresponding bits in the operands is 1.
Syntax
flex.bitwise.or(a, b)
Parameters
| Parameter | Type | Required | Description |
|---|---|---|---|
a |
number (integer) | Yes | First operand |
b |
number (integer) | Yes | Second operand |
Returns
Type: number (integer)
The result of the bitwise OR operation.
Examples
Example 1: Basic OR Operation
RETURN flex.bitwise.or(12, 10) AS result
Output:
result
------
14
(Binary: 1100 OR 1010 = 1110 = 14)
Example 2: Combining Permission Flags
WITH 1 AS readFlag, 2 AS writeFlag
RETURN flex.bitwise.or(readFlag, writeFlag) AS readWritePermission
Output:
readWritePermission
-------------------
3
(Binary: 01 OR 10 = 11 = 3)
Example 3: Setting Multiple Flags
MATCH (u:User {id: 123})
SET u.permissions = flex.bitwise.or(u.permissions, 4) // Add execute permission
Notes
- Operates on 32-bit signed integers in JavaScript
- Both operands are converted to integers if needed
- Commonly used for combining flags and setting bits

Frequently Asked Questions 2
What does flex.bitwise.or return?
It returns an integer where each bit is 1 if the corresponding bit in either (or both) input operands is 1. For example, flex.bitwise.or(5, 3) returns 7.
How can I combine permission flags with bitwise.or?
Use flex.bitwise.or(existingFlags, newFlag) to add a permission bit. For example, flex.bitwise.or(permissions, 4) sets the third bit.
