Dynamic Report Introduction In many Oracle APEX applications, different reports require different SQL queries. Instead of hard-coding these queries into the application, users can store multiple SQL queries in a database table. These queries may contain bind variables (for example, :P_DEPTNO or :P_EMPNO ). When a user selects a report, the application automatically: Identifies the bind variables used in the selected SQL query. Dynamically generates input fields for those parameters. Prompts the user to enter the required values. Executes the query using the provided inputs. Refreshes the report with the filtered results. This approach allows a single report region to execute multiple dynamic queries without requiring any code changes. Step-by-Step Implementation Step 1 Create the QUERY_MASTER Table This table acts as our repository for SQL queries. We will...
Oracle APEX • PL/SQL • Dynamic Reporting Have you ever needed to build a dashboard where users select a report from a dropdown list, and the page dynamically renders the query results? A common design pattern is to centralize your report queries in a database table: REPORTS_TABLE ( QUERY_ID , REPORT_NAME , QUERIES , CREATE_BY , CREATE_DATE ) However, if you've tried implementing this with an Interactive Report or Interactive Grid , you likely ran into database metadata conflicts or compilation errors when switching between reports. In this post, we will explore why standard reports struggle with dynamic structures and provide a step-by-step guide to building a fully dynamic report viewer using Classic Reports and Generic Columns in Oracle APEX. The Challenge: Fixed Metadata vs. Dynamic Columns Oracle APEX Intera...
