# Querying from StarRocks

StarRocks allows you to query table formats like Hudi, Delta and Iceberg tables using our [external catalog](https://docs.starrocks.io/docs/data_source/catalog/catalog_overview/) feature.
Users do not need additional configurations to work with OneTable synced tables.

For more information and required configurations refer to:
* [Hudi Catalog](https://docs.starrocks.io/docs/data_source/catalog/hudi_catalog/)
* [Delta Lake Catalog](https://docs.starrocks.io/docs/data_source/catalog/deltalake_catalog/)
* [Iceberg Catalog](https://docs.starrocks.io/docs/data_source/catalog/iceberg_catalog/)

For hands on experimentation, please follow [Creating your first interoperable table](/docs/how-to#create-dataset)
to create OneTable synced tables followed by [Hive Metastore](/docs/hms) to register the target table
in Hive Metastore. Once done, please follow the below high level steps:
1. Start the StarRocks server
2. From the directory where you have installed mysql-cli: login by running `mysql -P 9030 -h 127.0.0.1 -u root --prompt="StarRocks > "`.

]}

<TabItem value="hudi">
:::tip Note:
If you are following the example from [Hive Metastore](/docs/hms), you can query the OneTable synced Hudi table
from StarRocks using the below query.
```sql md title="sql"
CREATE EXTERNAL CATALOG unified_catalog_hms PROPERTIES ("type" = "unified","unified.metastore.type" = "hive", "hive.metastore.uris" = "thrift://hivemetastore:9083" );
SELECT * FROM unified_catalog_hms.hudi_db.<table_name>;
```

from StarRocks using the below query.
