groupBitAnd

Applies bit-wise AND for series of numbers.

groupBitAnd(expr)

Arguments

expr – An expression that results in UInt* or Int* type.

Return value

Value of the UInt* or Int* type.

Example

Test data:

binary     decimal
00101100 = 44
00011100 = 28
00001101 = 13
01010101 = 85

Query:

SELECT groupBitAnd(num) FROM t

Where num is the column with the test data.

Result:

binary     decimal
00000100 = 4

Examples

Bitwise AND example

CREATE TABLE t (num UInt32) ENGINE = Memory;
INSERT INTO t VALUES (44), (28), (13), (85);

-- Test data:
-- binary     decimal
-- 00101100 = 44
-- 00011100 = 28
-- 00001101 = 13
-- 01010101 = 85

SELECT groupBitAnd(num) FROM t;

-- Result:
-- binary     decimal
-- 00000100 = 4
