## Querying Oracle DB
Once you have added a Oracle DB data source, click on `+` button of the query manager to create a new query. There are two modes by which you can query SQL:
SQL mode can be used to write raw SQL queries. Select SQL mode from the dropdown and enter the SQL query in the editor. Click on the `run` button to run the query.
#### GUI mode
GUI mode can be used to query Oracle database without writing queries. Select GUI mode from the dropdown and then choose the operation **Bulk update using primary key**. Enter the **Table** name and **Primary key column** name. Now, in the editor enter the records in the form of an array of objects.
