HSQL Data Connection

Version

Application Scenario

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

Note:

1. In the HSQL database, avoid naming database tables with a number as the first character, otherwise, errors may occur during 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.

Connection Information Collection

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

• The database name

• The database storage path

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

Note:

If you are not the admin, you can configure data connections only after the admin assigns you the permission on Data Connection Management. For details, see Data Connection Permission Overview.

2. Select the icon of the HSQL database.as shown in the following figure.

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

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

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

Pattern is available after the database is connected by clicking Click to Connect Database, as shown in the following figure.

4. Click Test Connection. If the connection is successful, click Save, as shown in the following figure.

You can add database tables to FineBI by the following two methods.
