MySQL uses (64-bit) arithmetic for bit operations, so these operators have a maximum range
BIGINT
of 64 bits.
• [951]
|
Bitwise OR:
mysql> SELECT 29 | 15;
-> 31
The result is an unsigned 64-bit integer.
• [951]
&
Bitwise AND:
mysql> SELECT 29 & 15;
-> 13
The result is an unsigned 64-bit integer.
• [951]
^
Bitwise XOR:
mysql> SELECT 1 ^ 1;
-> 0
mysql> SELECT 1 ^ 0;
-> 1
mysql> SELECT 11 ^ 3;
-> 8
The result is an unsigned 64-bit integer.
• [951]
<<
Shifts a longlong (BIGINT) number to the left.
mysql> SELECT 1 << 2;
-> 4
The result is an unsigned 64-bit integer. The value is truncated to 64 bits. In particular, if the shift
count is greater or equal to the width of an unsigned 64-bit number, the result is zero.
• [951]
>>
Shifts a longlong (BIGINT) number to the right.
mysql> SELECT 4 >> 2;
-> 1
The result is an unsigned 64-bit integer. The value is truncated to 64 bits. In particular, if the shift
count is greater or equal to the width of an unsigned 64-bit number, the result is zero.
• [951]
~
Invert all bits.
