Test case:

create table t ( col varchar(32000) );

-- populate it with data
execute block
as
declare variable i integer;
begin
i= 0;
while (i < 200000) do begin
insert into t (col) values(mod(:i, 10));
i= i+1;
end
end;

select col from t group by 1;
-- unexpected NULLs and empty strings

select cast(col as integer) from t group by 1;
-- Overflow occurred during data type conversion.
-- conversion error from string "".
