> If we use cast boolean in where conditions to filter rows, in vectorization execution the filter is unable to filter rows, step to reproduce:
> {code:java}
> create table vtb (key string, value string);
> insert into table vtb values('0', 'val0'), ('false', 'valfalse'),('off', 'valoff'),('no','valno'),('vk', 'valvk');
> select distinct value from vtb where cast(key as boolean); {code}
> It's seems we don't generate a SelectColumnIsTrue to filter the rows if the casted type is string:
