Query HarperDB 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 HarperDB, DataGrip can work with live HarperDB data. This article shows how to establish a connection to HarperDB data in DataGrip and use the table editor to load HarperDB data.

Create a New Driver Definition for HarperDB

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

1. In DataGrip, click File -> New > Project and name the project
2. In the Database Explorer, click the plus icon () and select Driver.
3. In the Driver tab:
   • Set Name to a user-friendly name (e.g. "CData HarperDB 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.harperdb.jar).
   • Set Class to cdata.jdbc.harperdb.HarperDB.jar
   Additionally, in the advanced tab you can change driver properties and some other settings like VM Options, VM environment, VM home path, DBMS, etc
   • For most cases, change the DBMS type to "Unknown" in Expert options to avoid native SQL Server queries (Transact-SQL), which might result in an invalid function error
4. Click "Apply" then "OK" to save the Connection

Configure a Connection to HarperDB

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

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.harperdb.jar

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

   Set the Server, User, and Password connection properties to connect to HarperDB. Set UseSSL to secure connections with TLS/SSL.

3. Set URL to the connection string, e.g., jdbc:harperdb:Server=127.0.0.1;User=admin;Password=1234;
4. Click "Apply" and "OK" to save the connection string

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

Execute SQL Queries Against HarperDB

To browse through the HarperDB 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 City, CompanyName FROM Customers WHERE Country = 'US'
