HSQL Data Connection

Version

Application Scenario

This document describes how to connect to the HSQL (Hyper SQL) database.

Note:

1. In the HSQL database, it is advisable to avoid table names starting with numbers, as errors may occur after connection.

2. When you use an HSQL database, it will create an in-memory database. The database will occupy a large amount of memory if the data volume is large. Therefore, do not create a data connection to a built-in FineDB database in the FineBI project unless necessary.

Collecting Connection Information

Before connecting the database, you need to collect the following information.

1. The database name

2. The database storage path

1. Log in to FineBI as the admin, choose System Management > Data Connection > Data Connection Management, and click New Data Connection, as shown in the following figure.

Note:

If you are not an admin, you cannot configure the data connection until the admin assigns the Data Connection permission in System Management to you.

2. Select the icon of the HSQL database.

3. Enter the username and password, and modify the data connection URL by replacing PATH_TO_DB_FILES with the path to the database.

For example, if the built-in database is located at %FineBI%\webapps\webroot\WEB-INF\embed\finedb\db, you can fill Data Connection URL with the following path.

jdbc:hsqldb:file:D:\finebi\5.1.19\FineBI5.1\webapps\webroot\WEB-INF\embed\finedb\db

Pattern is greyed out before the database is connected. Therefore, you need to click Click to Connect Database to select Pattern, as shown in the following figure.

4. Click Test Connection. If the connection is successful, click Save.

You can add database tables to FineBI by adding database tables or adding SQL datasets.
