MySQL BIT_AND() function
BIT_AND() function
MySQL BIT_AND() function returns the bitwise AND 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 18446744073709551615.
What is Bitwise AND operation
A logical AND operation is performed on each pair of corresponding bits of two binary expressions of equal length.
In each pair, it returns 1 if the first bit is 1 AND the second bit is 1. Else, it returns 0.
Syntax:
BIT_AND(expr)
Where expr is a given expression.
MySQL Version : 5.6
Example: MySQL BIT_AND() function
The following MySQL statement performs Bitwise AND 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_AND('book_price') AS BITS
FROM book_mast group by book_id;
Sample Output:
mysql> SELECT book_id, BIT_AND('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 | +---------+------+ 16 rows in set, 16 warnings (0.04 sec)
