Connecting to ODBC Data Sources
After you create the ODBC DSN, you can use ODBC on Windows to directly connect to data that is defined by a schema, such as Hive, and data that is self-describing. Examples of self-describing data include HBase, Parquet, JSON, CSV,and TSV.
In some cases, you may want to use Drill Explorer to explore that data or to create a view before you connect to the data from a BI tool. For more information about Drill Explorer, see Using Drill Explorer on Windows to browse data and create views.
In an ODBC-compliant BI tool, use the ODBC DSN to create an ODBC connection with one of the methods applicable to the data source type:
| Data Source Type | ODBC Connection Method |
|---|---|
| Hive | Connect to a table. Connect to the table using custom SQL. Use Drill Explorer to create a view. Then use ODBC to connect to the view as if it were a table. |
| HBase Parquet JSON CSV TSV | Use Drill Explorer to create a view. Then use ODBC to connect to the view as if it were a table. Connect to the data using custom SQL. |
Note
The default schema that you configure in the DSN may or may not carry over to an application’s data source connections. You may need to re-select the schema.
