Connect to AlloyDB Data from Crystal Reports

Crystal Reports is a business intelligence application by SAP designed to help you analyze your data with well-formatted, pixel-perfect, and multi-page reports. When paired with CData Connect Cloud, Crystal Reports gets access to live AlloyDB data. This article demonstrates how to connect to AlloyDB using Connect Cloud and report on AlloyDB data in Crystal Reports.

CData Connect Cloud provides a pure SQL Server interface for AlloyDB, allowing you to query data from AlloyDB without replicating the data to a natively supported database. Using optimized data processing out of the box, CData Connect Cloud pushes all supported SQL operations (filters, JOINs, etc.) directly to AlloyDB, leveraging server-side processing to return the requested AlloyDB data quickly.

Configure AlloyDB Connectivity for Crystal Reports

Connectivity to AlloyDB from Crystal Reports is made possible through CData Connect Cloud. To work with AlloyDB data from Crystal Reports, we start by creating and configuring a AlloyDB connection.

1. Log into Connect Cloud, click Connections and click Add Connection
2. Select "AlloyDB" from the Add Connection panel
3. Enter the necessary authentication properties to connect to AlloyDB.

   The following connection properties are usually required in order to connect to AlloyDB.

   • Server: The host name or IP of the server hosting the AlloyDB database.
   • User: The user which will be used to authenticate with the AlloyDB server.
   • Password: The password which will be used to authenticate with the AlloyDB server.

   You can also optionally set the following:

   • Database: The database to connect to when connecting to the AlloyDB Server. If this is not set, the user's default database will be used.
   • Port: The port of the server hosting the AlloyDB database. This property is set to 5432 by default.

   Authenticating with Standard Authentication

   Standard authentication (using the user/password combination supplied earlier) is the default form of authentication.

   No further action is required to leverage Standard Authentication to connect.

   Authenticating with pg_hba.conf Auth Schemes

   There are additional methods of authentication available which must be enabled in the pg_hba.conf file on the AlloyDB server.

   Find instructions about authentication setup on the AlloyDB Server here.

   Authenticating with MD5 Authentication

   This authentication method must be enabled by setting the auth-method in the pg_hba.conf file to md5.

   Authenticating with SASL Authentication

   This authentication method must be enabled by setting the auth-method in the pg_hba.conf file to scram-sha-256.

   Authenticating with Kerberos

   The authentication with Kerberos is initiated by AlloyDB Server when the ∏ is trying to connect to it. You should set up Kerberos on the AlloyDB Server to activate this authentication method. Once you have Kerberos authentication set up on the AlloyDB Server, see the Kerberos section of the help documentation for details on how to authenticate with Kerberos.

4. Click Create & Test
5. Navigate to the Permissions tab in the Add AlloyDB Connection page and update the User-based permissions.

Add a Personal Access Token

If you are connecting from a service, application, platform, or framework that does not support OAuth authentication, you can create a Personal Access Token (PAT) to use for authentication. Best practices would dictate that you create a separate PAT for each service, to maintain granularity of access.

1. Click on your username at the top right of the Connect Cloud app and click User Profile.
2. On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
3. Give your PAT a name and click Create.
4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

Connect to AlloyDB from Crystal Reports using Connect Cloud

To establish a connection from Crystal Reports to CData Connect Cloud, you will need to download the JDBC Driver.

1. Open the Client Tools page of CData Connect Cloud.
2. In the Dev Tools section, click JDBC.
3. Download and run the setup file.
4. When the installation is complete, locate the JDBC Connect JAR file in the JDBC driver's installation directory, for example, C:\Program Files\CData\JDBC Driver for CData Connect\lib.
5. Copy the JDBC Connect JAR file (cdata.jdbc.connect.jar).

After copying the JDBC CData Connect JAR file, you will need to paste it into the Crystal Reports installation location and configure the connection to Connect Cloud.

1. Find the installation directory for Crystal Reports, for example, C:\Program Files (x86)\SAP BusinessObjects\SAP BusinessObjects Enterprise XI 4.0\java\lib
2. Paste the JDBC Connect JAR file into the Crystal Reports installation directory.
3. Go to the parent java folder. For example, C:\Program Files (x86)\SAP BusinessObjects\SAP BusinessObjects Enterprise XI 4.0\java This folder should contain a CRConfig file.
4. Open CRConfig in a text editor.
5. Add the path to the JDBC CData Connect JAR file in the of the CRConfig file, for example, C:\Program Files (x86)\SAP BusinessObjects\SAP BusinessObjects Enterprise XI 4.0\java\lib
6. Log into Crystal Reports and start a blank report.
7. In the Database Expert dialog, click Create New Connection.
8. Select the JDBC data source and the tables you want to add. Click OK.
9. In the Connection dialog, enter the Connection URL (e.g. jdbc:connect:AuthScheme=OAuth;) and Database Classname (e.g. cdata.jdbc.connect.ConnectDriver).
10. Click Finish. The Database Expert dialog displays all available connections.

You can now create reports with the connected data.
