## Reserved keywords
Druid SQL reserves certain keywords which are used in its query language. Apache Druid inherits all of the reserved keywords from [Apache Calcite](https://calcite.apache.org/docs/reference.html#keywords). In addition to these, the following reserved keywords are unique to Apache Druid:
* **CLUSTERED**
* **PARTITIONED**
To use the reserved keywords in queries, enclose them in double quotation marks. For example, the reserved keyword **PARTITIONED** can be used in a query if and only if it is correctly quoted:
```sql
SELECT "PARTITIONED" from druid.table
```
