Struct BitAndUpdatable 

struct BitAndUpdatable<T> {
    _phantom: PhantomData<T>,
}

Computes the bitwise AND of all non-null input values.

Example

statement ok
create table t (a int2, b int4, c int8);

statement ok
create materialized view mv as
select bit_and(a) a, bit_and(b) b, bit_and(c) c from t;

query III
select * from mv;
----
NULL NULL NULL

statement ok
insert into t values
   (6, 6, 6),
   (3, 3, 3),
   (null, null, null);

query III
select * from mv;
----
2 2 2

statement ok
delete from t where a = 3;

query III
select * from mv;
----
6 6 6

statement ok
drop materialized view mv;

statement ok
drop table t;
