**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.
```

{
        if (func->name == "sum")
            sums.push_back(func);
        else if (func->name == "count")
            counts.push_back(func);
        else
        {
            assert(func->name == "avg");
            avgs.push_back(func);
        }
    }
    bool canBeFused() const
    {
        
        if (sums.empty() && counts.empty())
            return false;
        if (sums.empty() && avgs.empty())
            return false;
        if (counts.empty() && avgs.empty())
            return false;
        return true;
    }
};
