MySQL bitwise operators

Bitwise operators are used to perform operations on binary values. MySQL supports several bitwise operators, including:

Bitwise AND (&): Returns a binary value where each bit is the result of a logical AND operation on the corresponding bits in the input values.
Example: SELECT 12 & 5; //Returns 4
Explanation: In binary, 12 is 1100 and 5 is 0101. The bitwise AND operation gives 0100, which is 4 in decimal.
Bitwise OR (|): Returns a binary value where each bit is the result of a logical OR operation on the corresponding bits in the input values.
Example: SELECT 12 | 5; //Returns 13
Explanation: In binary, 12 is 1100 and 5 is 0101. The bitwise OR operation gives 1101, which is 13 in decimal.
Bitwise XOR (^): Returns a binary value where each bit is the result of a logical XOR operation on the corresponding bits in the input values.
Example: SELECT 12 ^ 5; //Returns 9
Explanation: In binary, 12 is 1100 and 5 is 0101. The bitwise XOR operation gives 1001, which is 9 in decimal.
Bitwise NOT (~): Returns a binary value where each bit is flipped.
Example: SELECT ~12; //Returns -13
Explanation: In binary, 12 is 1100. The bitwise NOT operation gives 0011, but MySQL uses two's complement for negative numbers, so the result is -13 in decimal.
Left Shift (<<): Shifts the bits of the first operand to the left by the number of positions specified by the second operand. New bits on the right are filled with zeros.
Example: SELECT 5 << 2; //Returns 20
Explanation: In binary, 5 is 0101. Shifting two positions to the left gives 10100, which is 20 in decimal.
Right Shift (>>): Shifts the bits of the first operand to the right by the number of positions specified by the second operand. New bits on the left are filled with zeros.
Example: SELECT 5 >> 2; //Returns 1
Explanation: In binary, 5 is 0101. Shifting two positions to the right gives 0001, which is 1 in decimal.

Remember that these operators work on the binary representation of numbers, so their results can be surprising if you're thinking in terms of decimal numbers.

MySQL bitwise operators examples:
- MySQL provides bitwise operators for performing bitwise operations on integer values.
```
SELECT 5 & 3 AS bitwise_and, 5 | 3 AS bitwise_or, 5 ^ 3 AS bitwise_xor, ~5 AS bitwise_not;
```
How to use bitwise AND operator in MySQL:
- The bitwise AND operator (&) performs a bitwise AND operation on each pair of corresponding bits.
```
SELECT column1 & column2 AS result FROM table_name;
```
Bitwise OR operator in MySQL queries:
- The bitwise OR operator (|) performs a bitwise OR operation on each pair of corresponding bits.
```
SELECT column1 | column2 AS result FROM table_name;
```
XOR operator usage in MySQL bitwise operations:
- The XOR operator (^) performs a bitwise exclusive OR operation on each pair of corresponding bits.
```
SELECT column1 ^ column2 AS result FROM table_name;
```
Bitwise NOT operator in MySQL calculations:
- The bitwise NOT operator (~) inverts each bit of its operand.
```
SELECT ~column1 AS result FROM table_name;
```
Applying bitwise operators to integer values in MySQL:
- Bitwise operators can be used with integer columns or constants.
```
SELECT column1 & 15 AS result FROM table_name;
```
Using bitwise shifts in MySQL:
- Bitwise shift operators (<< and >>) shift bits to the left or right.
```
SELECT column1 << 2 AS left_shift, column1 >> 1 AS right_shift FROM table_name;
```
Performing bitwise operations with MySQL expressions:
- You can use complex expressions combining bitwise operators for specific calculations.
```
SELECT (column1 & 3) | (column2 << 2) AS result FROM table_name;
```
Bitwise operators and binary representation in MySQL:
- Internally, MySQL uses binary representation for integer values, making bitwise operations efficient.
```
SELECT BIN(column1 & column2) AS binary_result FROM table_name;
```
Examples of bitwise operations in MySQL queries:
- Applying bitwise operations to achieve specific outcomes in your queries.
```
SELECT (flags & 1) AS is_flag_set, (permissions | 8) AS add_permission FROM user_table;
```
