MySQL BIT_XOR() function

Last update on April 04 2022 13:10:37 (UTC/GMT +8 hours)

BIT_XOR() function

MySQL BIT_XOR() function returns the bitwise XOR of all bits in a given expression.

The calculation is performed on 64 bit precession.

If this function does not find a matching row, it returns 0.

What is Bitwise XOR operation

After taking two bit patterns of equal length, it performs logical XOR operation on each pair of corresponding bits (the first of each; the second of each; and so on).

The result in each position is 1 if the two bits are different, and 0 if they are same.

Syntax:

BIT_XOR(expr)

Where expr is a given expression.

MySQL Version: 5.6

Example: MySQL BIT_XOR() function

The following MySQL statement performs Bitwise XOR operation on the values of book_price column. A grouping on book_id column is also performed.

Sample table: book_mast

Code:

SELECT book_id, BIT_XOR('book_price') 
AS BITS from book_mast group by book_id;

Sample Output:

mysql> SELECT book_id, BIT_XOR('book_price') AS BITS from book_mast group by book_id;
+---------+------+
| book_id | BITS |
+---------+------+
| BK001   |    0 | 
| BK002   |    0 | 
| BK003   |    0 | 
| BK004   |    0 | 
| BK005   |    0 | 
| BK006   |    0 | 
| BK007   |    0 | 
| BK008   |    0 | 
| BK009   |    0 | 
| BK010   |    0 | 
| BK011   |    0 | 
| BK012   |    0 | 
| BK013   |    0 | 
| BK014   |    0 | 
| BK015   |    0 | 
| BK016   |    0 |
