MariaDB Connector for SAP Crystal Reports

The MariaDB Connector enables you to connect to MariaDB, a very powerful relational database engine, whether it's the free and open-source Community Server or Enterprise Platform.

In this article you will learn how to quickly and efficiently integrate MariaDB data in SAP Crystal Reports without coding. We will use high-performance MariaDB Connector to easily connect to MariaDB and then access the data inside SAP Crystal Reports.

Let's follow the steps below to see how we can accomplish that!

Download Documentation

Prerequisites

Before we begin, make sure you meet the following prerequisite:

If you already have a JRE installed, you can try using it too. However, if you experience any issues, we recommend using one of the distributions mentioned above (you can install an additional JRE next to the existing one; just don't forget to configure the default Java in the Windows Environment Variables).

Download MariaDB JDBC driver

To connect to MariaDB in SAP Crystal Reports, you will have to download JDBC driver for it, which we will use in later steps. Let's perform these little steps right away:

  1. Visit MariaDB website.
  2. Follow the instructions there, download the JDBC driver, and save it locally, e.g. to D:\Drivers\JDBC\mariadb-java-client.jar.
    It is recommended to use JDBC driver compiled for Java 8, if possible.
  3. Done! That was easy, wasn't it? Let's proceed to the next step.

Create ODBC Data Source (DSN) based on ZappySys JDBC Bridge Driver

Step-by-step instructions

To get data from MariaDB using SAP Crystal Reports we first need to create a DSN (Data Source) which will access data from MariaDB. We will later be able to read data using SAP Crystal Reports. Perform these steps:

  1. Download and install ODBC PowerPack.

  2. Open ODBC Data Sources (x64):

    Open ODBC Data Source
  3. Create a User data source (User DSN) based on ZappySys JDBC Bridge Driver

    Create new User DSN for ZappySys JDBC Bridge Driver
    • Create and use User DSN if the client application is run under a User Account. This is an ideal option in design-time, when developing a solution, e.g. in Visual Studio 2019. Use it for both type of applications - 64-bit and 32-bit.
    • Create and use System DSN if the client application is launched under a System Account, e.g. as a Windows Service. Usually, this is an ideal option to use in a production environment. Use ODBC Data Source Administrator (32-bit), instead of 64-bit version, if Windows Service is a 32-bit application.
  4. Now, we need to configure the JDBC connection in the new ODBC data source. Simply enter the Connection string, credentials, configure other settings, and then click Test Connection button to test the connection:

    MariadbDSN
    jdbc:mariadb://mariadb-instance-host-name:3306/MyDatabase
    D:\Drivers\JDBC\mariadb-java-client.jar
    root
    ****************
    []
    JDBC-ODBC Bridge driver data source settings

    Use these values when setting parameters:

    • Connection string: jdbc:mariadb://mariadb-instance-host-name:3306/MyDatabase
    • JDBC driver file(s): D:\Drivers\JDBC\mariadb-java-client.jar
    • User name: root
    • User password: ****************
    • Connection parameters: []

  5. You should see a message saying that connection test is successful:

    ODBC connection test is successful

    Otherwise, if you are getting an error, check out our Community for troubleshooting tips.

  6. We are at the point where we can preview a SQL query. For more SQL query examples visit JDBC Bridge documentation:

    MariadbDSN
    SELECT * FROM orders
    JDBC ODBC Bridge data source preview
    SELECT * FROM orders
    You can also click on the <Select Table> dropdown and select a table from the list.

    The ZappySys JDBC Bridge Driver acts as a transparent intermediary, passing SQL queries directly to the Trino JDBC driver, which then handles the query execution. This means the Bridge Driver simply relays the SQL query without altering it.

    Some JDBC drivers don't support INSERT/UPDATE/DELETE statements, so you may get an error saying "action is not supported" or a similar one. Please, be aware, this is not the limitation of ZappySys JDBC Bridge Driver, but is a limitation of the specific JDBC driver you are using.

  7. Click OK to finish creating the data source.

Read data in SAP Crystal Reports from the ODBC data source

  1. First of all, open SAP Crystal Reports and create the new Crystal Report.
    Create New Crystal Report

  2. And it will open the new data source selection window. Under ODBC(RDO) double click on the Make New Connection and Select the desired ODBC DSN, in our case we need to select MariadbDSN which we created in upper section. And Click on Next.

  3. Expand the Connection and under the data select the desired table(s) or view(s) and click Add > button and click on Next.

  4. Add the desired Fields to Display in the Reports. Here we are adding all fields and click on Finish.

  5. That's it and you will be able to load the data in the Report.

Using ZappySys Driver Custom Views and Stored Procedure in SAP Crystal Report

You can create parameterized Stored Procedure and Virtual Tables on the same Data Source (ODBC DSN or Data Gateway Data Source). Please refer to this article for the same. You can create procedures to encapsulate custom logic and then only pass handful parameters rather than long SQL to execute your API call.

Using Custom Views in the SAP Crystal Report

After establishing the connection with MariadbDSN Data Source you can use the custom view in SQL Crystal Report.

Using Custom Stored Procedure in the SAP Crystal Report

  1. First of all, create the custom stored procedure in the ZappySys Driver. Please refer to this article to create the custom stored procedure.
    ZappySys Driver Custom Stored Procedure
  2. After establishing the connection with MariadbDSN Data Source you can use the custom Stored Procedure in SQL Crystal Report. Same way you can write custom queries also in the query box.

Conclusion

In this article we showed you how to connect to MariaDB in SAP Crystal Reports and integrate data without any coding, saving you time and effort. It's worth noting that ZappySys JDBC Bridge Driver allows you to connect not only to MariaDB, but to any Java application that supports JDBC (just use a different JDBC driver and configure it appropriately).

We encourage you to download MariaDB Connector for SAP Crystal Reports and see how easy it is to use it for yourself or your team.
