BITNOT

Overview

The BITNOT function is used to perform a bitwise NOT operation on an integer type expression. This function can handle any integer type input and returns a result of the same type as the input. In addition to using the bitnot() function, the ~ operator can also be used to achieve the same functionality.

~expr

Parameters

• expr: An integer type expression that needs to be bitwise negated.

Return Value

• Returns the bitwise negated result of the same type as the input expr.

Example

1. Perform bitwise negation on a single integer:

SELECT BITNOT(100); -- Return result: -101
SELECT ~100;       -- Return result: -101

2. Perform bitwise NOT operation on integers in the query results:

   SELECT BITNOT(column_name) FROM table_name WHERE condition;
   SELECT ~column_name FROM table_name WHERE condition;
