``` text
┌─id─┬─value─┐
│  0 │     0 │
│  1 │     1 │
└────┴───────┘
```

Create a dictionary:

``` sql
CREATE DICTIONARY new_dictionary(id UInt64, value UInt64 DEFAULT 0) PRIMARY KEY id
SOURCE(CLICKHOUSE(HOST 'localhost' PORT tcpPort() USER 'default' TABLE 'dictionary_source_table')) LAYOUT(DIRECT());
```

Query:

``` sql
SELECT * FROM dictionary('new_dictionary');
```

Result:

```
