**Usage**
Postgres, MySQL, and Oracle support the expression `LEFT JOIN ... ON 1 = 1`, but ClickHouse does not.

It may be possible to replace `LEFT JOIN ... ON 1 = 1` with `CROSS JOIN`, but I want to use the query in the same form for lots of databases.

Please support the expression `LEFT JOIN ... ON 1 = 1`.


**Detailed SQL**
```SQL
CREATE TABLE test
(
    `name` Nullable(String),
    `id` int
)
ENGINE = Log();

insert into test values ('a', 1) ('b', 2) (null, 3);

select * from test t1 left join (select * from test ) t2 on 1 = 1   
-- DB::Exception: Not equi-join ON expression: 1 = 1. No columns in one of equality side.: While processing 1 = 1.
```

{
    data = join.data;
    from_storage_join = true;
    bool multiple_disjuncts = !table_join->oneDisjunct();
    if (multiple_disjuncts)
        throw Exception("StorageJoin with ORs is not supported", ErrorCodes::NOT_IMPLEMENTED);
    for (auto & map : data->maps)
    {
        joinDispatch(kind, strictness, map, [this](auto kind_, auto strictness_, auto & map_)
        {
            used_flags.reinit<kind_, strictness_>(map_.getBufferSizeInCells(data->type) + 1);
        });
    }
}
const ColumnWithTypeAndName & HashJoin::rightAsofKeyColumn() const
{
    
    return savedBlockSample().getByName(table_join->getOnlyClause().key_names_right.back());
}
}
