**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.
```

return;
    }
    if (kind == ASTTableJoin::Kind::Right || kind == ASTTableJoin::Kind::Full)
    {
        materializeBlockInplace(block);
        if (nullable_left_side)
            JoinCommon::convertColumnsToNullable(block);
    }
    if (overDictionary())
    {
        using Kind = ASTTableJoin::Kind;
        using Strictness = ASTTableJoin::Strictness;
        auto & map = std::get<MapsOne>(data->maps[0]);
        std::vector<const std::decay_t<decltype(map)>*> maps_vector;
        maps_vector.push_back(&map);
        if (kind == Kind::Left)
        {
            switch (strictness)
            {
            case Strictness::Any:
            case Strictness::All:
                    joinBlockImpl<Kind::Left, Strictness::Any>(block, sample_block_with_columns_to_add, maps_vector);
                    break;

                    break;
            case Strictness::Anti:
