MySQL commonly used examples of operator operations

Operator priority order highest priority: =
1 ||, or, xor
2 &&, and
3 between, case, when, then, else
4 =, <=>,> =,>, <=, <, <>,! =, Is, like, regexp, in
5 |
6 &
7 <<, >>
8 -, +
9 *, /, div,%, mod
10 ^
11 - (unary minus), ~ (unary bit inversion)
12!, Not
Lowest priority binary, collate

Arithmetic operators plus
mysql tutorial> select 1 + 2;
Less
mysql> select 2-1;
Multiply
mysql> select 2 * 3;
except
mysql> select 5/3;
Business
mysql> select 5 div 2;
mold
mysql> select 5% 2, mod (5,2);

Logical operators are not
mysql> select not 0, not 1, not null;
mysql> select! 0,! 1,! null;
versus
mysql> select (1 and 1), (0 and 1), (3 and 1), (1 and null);
mysql> select (1 && 1), (0 && 1), (3 && 1), (1 && null);
or
mysql> select (1 or 0), (0 or 0), (1 or null), (1 or 1), (null or null);
mysql> select (1 || 0), (0 || 0), (1 || null), (1 || 1), (null || null);
Exclusive or
mysql> select (1 xor 1), (0 xor 0), (1 xor 0), (0 xor 1), (null xor 1);
mysql> select (1 ^ 1), (0 ^ 0), (1 ^ 0), (0 ^ 1), (null ^ 1);

The comparison operator is equal to
mysql> select 1 = 0,1 = 1, null = null;
not equal to
mysql> select 1 <> 0,1 <> 1, null <> null;
Equal to safety
mysql> select 1 <=> 1,2 <=> 0,0 <=> 0, null <=> null;
Less than
mysql> select 'a' <'b', 'a' <'a', 'a' <'c', 1 <2;
Less than or equal to
mysql> select 'bdf' <= 'b', 'b' <= 'b', 0 <1;
more than the
mysql> select 'a'> 'b', 'abc'> 'a', 1> 0;
greater or equal to
mysql> select 'a'> = 'b', 'abc'> = 'a', 1> = 0, 1> = 1;
between
mysql> select 10 between 10 and 20, 9 between 10 and 20;
in
mysql> select 1 in (1,2,3), 't' in ('t', 'a', 'b', 'l', 'e'), 0 in (1,2);
is null
mysql> select 0 is null, null is null;
is not null
mysql> select 0 is not null, null is not null;
like
mysql> select 123456 like '123%', 123456 like '% 123%', 123456 like '% 321%';
regexp
mysql> select 'abcdef' regexp 'ab', 'abcdefg' regexp 'k';

Bitwise operators and
mysql> select 2 & 3;
mysql> select 2 & 3 & 4;
Bit or
mysql> select 2 | 3;
Exclusive OR
mysql> select 2 ^ 3;
Bit reversed
mysql> select ~ 1, ~ 18446744073709551614;
Bit right shift
mysql> select 100 >> 3;
Bit left
mysql> select 100 << 3;
