+
+ClickHouse supports integration with multiple catalogs (OneLake, Unity, Glue, Polaris, etc.). This guide will walk you through the steps to query your data stored in Microsoft OneLake using ClickHouse and [OneLake](https://learn.microsoft.com/en-us/fabric/onelake/onelake-overview).
+
+Microsoft OneLake supports multiple table formats for their lakehouse. With ClickHouse, you can query Iceberg tables.
+
+:::note
+As this feature is beta, you will need to enable it using:
+`SET allow_database_iceberg = 1;`
+:::
+
+## Gathering Requirements OneLake {#gathering-requirements}
+
+Before querying your table in Microsoft Fabric, you'll need to collect the following information:
+
+- A OneLake tenant ID (Your Entra ID)
+- A client ID
+- A client secret
+- A warehouse ID and a data item ID
+
+See [Microsoft OneLake's documentation](http://learn.microsoft.com/en-us/fabric/onelake/table-apis/table-apis-overview#prerequisites) for help finding these values.
+
+## Creating a connection between OneLake and ClickHouse {#creating-a-connection-between-unity-catalog-and-clickhouse}
+
+With the required info above you can now create a connection between Microsoft OneLake and ClickHouse, but before that you need to enable catalogs:
+
+```sql
+SET allow_database_iceberg=1
+```
+
+### Connect to OneLake {#connect-onelake}
+
+```sql
+CREATE DATABASE onelake_catalog
+ENGINE = DataLakeCatalog('https://onelake.table.fabric.microsoft.com/iceberg')
+SETTINGS
+catalog_type = 'onelake',
+warehouse = 'warehouse_id/data_item_id',
+onelake_tenant_id = '',
+oauth_server_uri = 'https://login.microsoftonline.com//oauth2/v2.0/token',
+auth_scope = 'https://storage.azure.com/.default',
+onelake_client_id = '',
+onelake_client_secret = ''
+```
+
+## Querying OneLake using ClickHouse {#querying-onelake-using-clickhouse}
+
+Now that the connection is in place, you can start querying OneLake:
+
+```sql
+SHOW TABLES FROM onelake_catalog
+
+Query id: 8f6124c4-45c2-4351-b49a-89dc13e548a7
+
+ ┌─name──────────────────────────┐

+4. │ year_2020.green_tripdata_2020 │
+5. │ year_2022.green_tripdata_2022 │
+ └───────────────────────────────┘
+```
+
+If you're using the Iceberg client, only the Delta tables with Uniform-enabled will be shown:
+
+To query a table:
+
+```sql
+SELECT *
+FROM onelake_catalog.`year_2017.green_tripdata_2017`
+LIMIT 1
+
+Query id: db6b4bda-cc58-4ca1-8891-e0d14f02c890

+```
+
+:::note Backticks required
+Backticks are required because ClickHouse doesn't support more than one namespace.
+:::
+
+To inspect the table DDL:
+
+```sql
+SHOW CREATE TABLE onelake_catalog.`year_2017.green_tripdata_2017`
