Get the Report →Create Reports with Amazon Athena Data in SAP Crystal Reports
Use the Report Wizard to design a report based on up-to-date Amazon Athena data.
Crystal Reports has many options for offloading data processing to remote data; this enables real-time reporting. The CData ODBC Driver for Amazon Athena brings this capability to Crystal Reports. This article shows how to create a report on Amazon Athena data that refreshes when you run the report.
About Amazon Athena Data Integration
CData provides the easiest way to access and integrate live data from Amazon Athena. Customers use CData connectivity to:
- Authenticate securely using a variety of methods, including IAM credentials, access keys, and Instance Profiles, catering to diverse security needs and simplifying the authentication process.
- Streamline their setup and quickly resolve issue with detailed error messaging.
- Enhance performance and minimize strain on client resources with server-side query execution.
Users frequently integrate Athena with analytics tools like Tableau, Power BI, and Excel for in-depth analytics from their preferred tools.

Getting Started
Refer to the given table for the tools and versions used for this article:
Application Name | Version |
---|---|
SAP Crystal Reports 2020 | SP3 |
ODBC Driver | 23.0.8565 |
Connect to Amazon Athena Data
If you have not already, specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.
Authenticating to Amazon Athena
To authorize Amazon Athena requests, provide the credentials for an administrator account or for an IAM user with custom permissions: Set AccessKey to the access key Id. Set SecretKey to the secret access key.
Note: Though you can connect as the AWS account administrator, it is recommended to use IAM user credentials to access AWS services.
Obtaining the Access Key
To obtain the credentials for an IAM user, follow the steps below:
- Sign into the IAM console.
- In the navigation pane, select Users.
- To create or manage the access keys for a user, select the user and then select the Security Credentials tab.
To obtain the credentials for your AWS root account, follow the steps below:
- Sign into the AWS Management console with the credentials for your root account.
- Select your account name or number and select My Security Credentials in the menu that is displayed.
- Click Continue to Security Credentials and expand the Access Keys section to manage or create root account access keys.
Authenticating from an EC2 Instance
If you are using the CData Data Provider for Amazon Athena 2018 from an EC2 Instance and have an IAM Role assigned to the instance, you can use the IAM Role to authenticate. To do so, set UseEC2Roles to true and leave AccessKey and SecretKey empty. The CData Data Provider for Amazon Athena 2018 will automatically obtain your IAM Role credentials and authenticate with them.
Authenticating as an AWS Role
In many situations it may be preferable to use an IAM role for authentication instead of the direct security credentials of an AWS root user. An AWS role may be used instead by specifying the RoleARN. This will cause the CData Data Provider for Amazon Athena 2018 to attempt to retrieve credentials for the specified role. If you are connecting to AWS (instead of already being connected such as on an EC2 instance), you must additionally specify the AccessKey and SecretKey of an IAM user to assume the role for. Roles may not be used when specifying the AccessKey and SecretKey of an AWS root user.
Authenticating with MFA
For users and roles that require Multi-factor Authentication, specify the MFASerialNumber and MFAToken connection properties. This will cause the CData Data Provider for Amazon Athena 2018 to submit the MFA credentials in a request to retrieve temporary authentication credentials. Note that the duration of the temporary credentials may be controlled via the TemporaryTokenDuration (default 3600 seconds).
Connecting to Amazon Athena
In addition to the AccessKey and SecretKey properties, specify Database, S3StagingDirectory and Region. Set Region to the region where your Amazon Athena data is hosted. Set S3StagingDirectory to a folder in S3 where you would like to store the results of queries.
If Database is not set in the connection, the data provider connects to the default database set in Amazon Athena.
When configuring the DSN, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.
Design a Report in SAP Crystal Reports
Follow the procedure below to use the SAP Crystal Reports tool to create the Amazon Athena connection and Design a Report.
- File -> New -> Standard Report.
- Expand the ODBC (RDO) node under Create New Connection and double-click on "Make a New Connection". Select CData Amazon Athena Sys or any other source to prepare the report. Click on NEXT and FINISH.
- Configure the data source by selecting the tables needed in the report and clicking NEXT.
- You can also link tables from the Amazon Athena data in SAP Crystal Reports. Click on NEXT after adding the links between tables.
- After the tables are selected, select the fields you want displayed in the report from the selected table, followed by NEXT.
- Select the "Group By" field to group the information on the report.
- Sort the groups based on summarised totals and click on NEXT.
Create a Chart
After selecting a column to group by, the Standard Report Creation Wizard presents the option to create a chart. Follow the steps below to create a chart aggregating the Name column's values.
- In the Standard Report Creation Wizard, select the Bar Chart option and select the column you grouped by in the "On change of" menu.
- In the Show Summary menu, select the summary you created.
- Select filters and a template, as needed, to finish the wizard.
Select a template for the report to preview the finished report and view the chart populated with your data.
The Final Report
You can now see that the report contains all the fields specified.
Working with Remote Data
To ensure that you see updates to data, click File and clear the "Save Data with Report" option. As you interact with the report, for example, drilling down to hidden details, Crystal Reports executes SQL queries to retrieve the data needed to display the report. To reload data you have already retrieved, refresh or rerun the report.
You can offload processing onto the driver by hiding details elements and enabling server-side grouping. To do this, you need to select a column to group by in the report creation wizard.
- Click File -> Report Options and select the "Perform Grouping On Server" option.
- Click Report -> Section Expert and select the Details section of your report. Select the "Hide (Drill-Down OK)" option.
When you preview your report with the hidden details, Crystal Reports executes a GROUP BY query. When you double-click a column in the chart to drill down to details, Crystal Reports executes a SELECT WHERE query that decreases load times by retrieving only the data needed.
At this point, you have created a SAP Crystal report built on top of live Amazon Athena data using SAP Crystal Reports and CData ODBC driver.
