BIT_OR

Syntax

BIT_OR(expr)

Description

Returns the bitwise OR of all bits in expr. The calculation is performed with 64-bit (BIGINT) precision. It is an aggregate function, and so can be used with the GROUP BY clause.

From MariaDB 10.2.0, BIT_OR can be used as a window function.

Examples

CREATE TABLE vals (x INT);

INSERT INTO vals VALUES(111),(110),(100);

SELECT BIT_AND(x), BIT_OR(x), BIT_XOR(x) FROM vals;
+------------+-----------+------------+
| BIT_AND(x) | BIT_OR(x) | BIT_XOR(x) |
+------------+-----------+------------+
|        100 |       111 |        101 |
+------------+-----------+------------+

As an aggregate function:

CREATE TABLE vals2 (category VARCHAR(1), x INT);

INSERT INTO vals2 VALUES
  ('a',111),('a',110),('a',100),
  ('b','000'),('b',001),('b',011);

SELECT category, BIT_AND(x), BIT_OR(x), BIT_XOR(x) 
  FROM vals GROUP BY category;
+----------+------------+-----------+------------+
| category | BIT_AND(x) | BIT_OR(x) | BIT_XOR(x) |
+----------+------------+-----------+------------+
| a        |        100 |       111 |        101 |
| b        |          0 |        11 |         10 |
+----------+------------+-----------+------------+
