~ (bitwise NOT)

The bitwise NOT operator (~) is a unary operator used to invert the bits of a binary value. It converts each 0 to a 1 and each 1 to a 0, resulting in the ones’ complement of the original value.

Syntax

~ expr --> integer

expr ::= integer

Arguments

Parameter

Description

expr

Integer expression

Returns

Returns an integer that is the bitwise NOT of the input and preserves the data type of the argument supplied.

Notes

  • If the value is NULL, the result is NULL.

Examples

master=> SELECT ~16, ~24;
-17,-25

master=> SELECT ~101, ~110;
-102,-111

master=> SELECT ~32, ~64;
-33,-65

master=> CREATE OR REPLACE TABLE t (xtinyInt tinyInt, xsmallInt smallInt, xint int, xbigInt bigInt);

master=> INSERT INTO t VALUES (1,1,1,1);

master=> SELECT ~xtinyInt, ~xsmallInt, ~xint, ~xbigInt from t;
