Article No.: 013
SAP Crystal Reports is a powerful tool for designing and generating detailed reports from a variety of data sources. While its drag-and-drop interface suits many reporting needs, advanced users often need greater flexibility and precision in data retrieval. This is where working with SQL queries within Crystal Reports becomes invaluable. Incorporating SQL queries allows for customized data selection, filtering, and aggregation directly at the database level, optimizing report performance and expanding reporting capabilities.
This article explains how to work effectively with SQL queries in Crystal Reports, including creating, modifying, and integrating SQL commands into your reports.
Using the “Add Command” Feature
When creating a new report, instead of selecting tables, choose “Add Command” in the database expert.
Enter your custom SQL query in the command editor.
You can include parameters to prompt users for input during report execution.
Example:
SELECT CustomerID, CustomerName, OrderDate, TotalAmount
FROM Orders
WHERE OrderDate >= {?StartDate} AND OrderDate <= {?EndDate}
Using SQL Expressions
Direct SQL in Record Selection Formula
Open Crystal Reports and start a new report.
In the Database Expert, select your data source and choose “Add Command.”
Enter the following SQL with parameters:
SELECT CustomerID, CustomerName, OrderID, OrderDate, TotalAmount
FROM Orders
WHERE CustomerID = {?CustomerID}
AND OrderDate BETWEEN {?StartDate} AND {?EndDate}
Crystal Reports will prompt you to define the parameter types (e.g., string for CustomerID, date for StartDate/EndDate).
After setting up, finish the report design with fields from the command.
Mastering SQL queries within SAP Crystal Reports unlocks a new level of report customization and performance optimization. By integrating custom SQL commands, leveraging parameters, and understanding how Crystal Reports interacts with SQL, report developers can deliver precise, efficient, and dynamic reports that meet complex business needs.
Whether you are querying a simple table or executing advanced joins and subqueries, SQL empowers your Crystal Reports to deliver richer insights and more responsive reporting solutions.
