**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.
```

{
    Columns materialized;
    materialized.reserve(names.size());
    for (const auto & column_name : names)
    {
        materialized.emplace_back(materializeColumn(block, column_name));
    }
    return materialized;
}
ColumnRawPtrs getRawPointers(const Columns & columns)
{
    ColumnRawPtrs ptrs;
    ptrs.reserve(columns.size());
    for (const auto & column : columns)
        ptrs.push_back(column.get());
    return ptrs;
}

    {
        auto & col = block.getByPosition(i);
        col.column = recursiveRemoveLowCardinality(col.column);
        col.type = recursiveRemoveLowCardinality(col.type);
    }
}
