---------------------------------
Description:
SQL:
{code:java}
// code placeholder
select * from xxx where cast(n as boolean){code}
In calcite, casting a non-zero number to boolean is always false, which is
different with other databases. The other databases shows that casting zero to
boolean is false and casting non-zero value to boolean is true.
