Query FHIR Data in DataGrip

DataGrip is a database IDE that allows SQL developers to query, create, and manage databases. When paired with the CData JDBC Driver for FHIR, DataGrip can work with live FHIR data. This article shows how to establish a connection to FHIR data in DataGrip.

Create a New Driver Definition for FHIR

The steps below describe how to create a new Data Source in DataGrip for FHIR.

1. In DataGrip, click File -> New > Project and name the project 👁 Creating a new DataGrip project.
   
2. In the Database Explorer, click the plus icon () and select Driver. 👁 Adding a new Driver.
   
3. In the Driver tab:
   • Set Name to a user-friendly name (e.g. "CData FHIR Driver")
   • Set Driver Files to the appropriate JAR file. To add the file, click the plus (), select "Add Files," navigate to the "lib" folder in the driver's installation directory and select the JAR file (e.g. cdata.jdbc.fhir.jar).
   • Set Class to cdata.jdbc.fhir.FHIR.jar
4. Click "Apply" then "OK" to save the Connection 👁 A configured Driver (Salesforce is shown).
   

Configure a Connection to FHIR

1. Once the connection is saved, click the plus (), then "Data Source" then "CData FHIR Driver" to create a new FHIR Data Source.
2. In the new window, configure the connection to FHIR with a JDBC URL.

   Built-in Connection String Designer

   For assistance in constructing the JDBC URL, use the connection string designer built into the FHIR JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

    java -jar cdata.jdbc.fhir.jar
    

   Fill in the connection properties and copy the connection string to the clipboard.

   Set URL to the Service Base URL of the FHIR server. This is the address where the resources are defined in the FHIR server you would like to connect to. Set ConnectionType to a supported connection type. Set ContentType to the format of your documents. Set AuthScheme based on the authentication requirements for your FHIR server.

   Generic, Azure-based, AWS-based, and Google-based FHIR server implementations are supported.

   Sample Service Base URLs

   • Generic: http://my_fhir_server/r4b/
   • Azure: https://MY_AZURE_FHIR.azurehealthcareapis.com/
   • AWS: https://healthlake.REGION.amazonaws.com/datastore/DATASTORE_ID/r4/
   • Google: https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/fhirStores/FHIR_STORE_ID/fhir/

   Generic FHIR Instances

   The product supports connections to custom instances of FHIR. Authentication to custom FHIR servers is handled via OAuth (read more about OAuth in the Help documentation. Before you can connect to custom FHIR instances, you must set ConnectionType to Generic.

   👁 Using the built-in connection string designer to generate a JDBC URL (Salesforce is shown.)
   
3. Set URL to the connection string, e.g.,

   jdbc:fhir:URL=http://test.fhir.org/r4b/;ConnectionType=Generic;ContentType=JSON;AuthScheme=None;

4. Click "Apply" and "OK" to save the connection string 👁 A configured Data Source (Salesforce is shown).
   

At this point, you will see the data source in the Data Explorer.

Execute SQL Queries Against FHIR

To browse through the FHIR entities (available as tables) accessible through the JDBC Driver, expand the Data Source.

To execute queries, right click on any table and select "New" -> "Query Console."

In the Console, write the SQL query you wish to execute. For example:

SELECT Id, [name-use] FROM Patient WHERE [address-city] = 'New York'
