|
||
|
|
└────┴───────┘
|
||
|
|
```
|

Dictionary の作成:
|
||
|
|
|

|
|
``` 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());
|
||
|
|
```
|
||
|
|
|
||
|
|
クエリ:
|
||
|
|
|
||
|
|
``` sql
|
||
|
|
SELECT * FROM dictionary('new_dictionary');
|
||
|
|
```
