Struct BoolOrUpdatable 

struct BoolOrUpdatable;

Returns true if any non-null input value is true, otherwise false.

Example

statement ok
create table t (b boolean);

statement ok
create materialized view mv as select bool_or(b) from t;

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

statement ok
insert into t values (true), (false), (null);

query T
select * from mv;
----
t

statement ok
delete from t where b is true;

query T
select * from mv;
----
f

statement ok
drop materialized view mv;

statement ok
drop table t;
