Reproducible: Always

Steps to Reproduce:

create table cls_0(i integer, j integer, k string);
insert into cls_0 values
( 1, 99, 'b'),
( 2, 99, 'b'),
( 3, 99, 'b'),
( 4, 99, 'a'),
( 5, 99, 'a'),
( 6, 99, 'a'),
( 7, 33, 'b'),
( 8, 33, 'b'),
( 9, 33, 'b'),
( 10, 33, 'a'),
( 11, 33, 'a'),
( 12, 33, 'a');
select * from cls_0;

-- The metric functions over all columns are derived in one blow.
-- The result can be cached for easy recall
create procedure cls_0_statistics()
begin
create table cls_0_statistics ( col string, fcn string, tpe string, val string);
insert into cls_0_statistics values
('i', 'min', 'int', (select cast( min( i ) as string) from cls_0)),
('i', 'max', 'int', (select cast( min( i ) as string) from cls_0)),
('j', 'min', 'int', (select cast( min( i ) as string) from cls_0));
end;

select * from cls_0_statistics;
