The BITNOT function in H2 database is used to perform a bitwise NOT operation on a given integer value.

2. Syntax​

The syntax for the BITNOT function in H2 database is as follows:

BITNOT(value)

Arguments​

  • value: The integer value on which the bitwise NOT operation needs to be performed.

Return​

  • The BITNOT function returns the result of the bitwise NOT operation as an integer value.

3. Notes​

  • The BITNOT function in H2 database expects the input value to be an integer. If the value is not an integer, it will be implicitly converted to an integer before performing the bitwise NOT operation.
  • The bitwise NOT operation inverts each bit of the input value, resulting in a bitwise complement.

4. Examples​

Here are a few examples demonstrating the usage of the BITNOT function in H2 database:

Example 1 - Performing bitwise NOT on an integer value:​

SELECT BITNOT(5) AS result;

Output:

result
------
-6

Example 2 - Performing bitwise NOT on a column:​

CREATE TABLE numbers (
  id INT PRIMARY KEY,
  value INT
);

INSERT INTO numbers VALUES (1, 10), (2, 15), (3, 7);

SELECT id, value, BITNOT(value) AS result
FROM numbers;

Output:

id | value | result
---+-------+--------
1  | 10    | -11
2  | 15    | -16
3  | 7     | -8
