How to Upload Multi-Sheet Excel Files into Oracle APEX

Oracle APEX · Step-by-Step Guide Importing one Excel sheet is easy with the built-in wizard. Importing a workbook with related parent and child sheets — and keeping the keys straight — takes a bit more care. Here's the full pattern. Excel is still the undisputed king of business data. As Oracle APEX developers, we're frequently asked to build import utilities. While importing a single-sheet Excel file in APEX is straightforward using the built-in wizard or APEX_DATA_PARSER , things get trickier when a single workbook contains multiple worksheets with relational data — like a parent header and child lines. In this post, we'll parse a multi-sheet Excel file, assign separate database sequences for primary keys, maintain the parent-child relationship, and stage everything into APEX Collections for reporting.

Dynamic Report - Part 2

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 - Dynamic Reporting

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...
