Calculator Form
Formula Used
Selected formula: Weighted Sort Score
(qty * unit_price * (1 - discount / 100) * (1 + tax / 100)) + (priority * 10)
The calculated item value is produced for each row. The result is then sorted by that value. For query level ordering, place the equivalent expression in the query or in a database view when the required source columns are available.
Planning note: ORDERS_BLK.SORT_VALUE is treated as the screen calculated item name for exported review.
How to Use This Calculator
- Paste block data with a header row.
- Select a built-in formula or choose a custom expression.
- Pick ascending or descending sorting.
- Set null handling and tie breaker rules.
- Submit the form and review the ranked table.
- Download CSV or PDF files for testing notes.

Why Sort Calculated Items Carefully?
Oracle Forms often shows values that are not stored in a table. A block may calculate totals, margins, tax, priority scores, or weighted amounts after each record is fetched. Users still expect those values to sort like normal database columns. This calculator helps you test that idea before changing a form trigger, query, or view.
What This Tool Does
The page accepts sample block rows in comma separated format. Each row can include quantity, unit price, unit cost, discount, tax, and priority. The selected formula creates a calculated item value for every row. The sorter then orders the rows by that value, applies null handling, resolves ties, and shows a ranked result table.
Why It Helps Form Design
A calculated item can be simple on screen, yet difficult in a data block. Standard query ordering works best with database fields or expressions available to the query. When a value is created after fetch, the developer may need another strategy. Common choices include a query expression, a database view, a stored function, or a post-query record group style review. Testing with sample values makes the choice clearer.
Interpreting the Results
The first ranked row is the record that matches your selected direction. Ascending order places the smallest calculated value first. Descending order places the largest value first. The statistics panel summarizes total, average, minimum, and maximum values. These figures help confirm whether the formula behaves as expected.
Good Practice Notes
Use column names that match your block item meaning. Keep formulas readable. Avoid hidden assumptions about null values. Decide how ties should behave before users report inconsistent sorting. For production work, confirm whether the formula can be moved into the query, because database sorting is usually more stable than screen-only sorting. Export the result and share it with developers, testers, or analysts.
Testing Before Changes
Before editing a live module, paste a small set of trusted records. Compare the calculated order with user expectations. Then test edge cases, such as zero quantity, high discount, missing cost, equal scores, and negative margin. A small rehearsal can prevent confusing block behavior and reduce rework during acceptance testing. It also creates proof for later review meetings and sign-off notes.
FAQs
What does this calculator sort?
It sorts sample data block rows by a calculated item value. The value may represent net amount, taxed amount, margin, discount value, weighted score, or your custom arithmetic expression.
Can Oracle Forms sort directly on a calculated item?
Often the safest approach is to sort by a query expression, database view column, or stored calculation. A screen-only calculated item may not be available to normal query ordering.
What data format should I enter?
Enter comma separated rows. The first row must be headers. Useful headers include item, qty, unit_price, unit_cost, discount, tax, and priority.
What does null handling mean?
Null handling decides where rows with missing or invalid calculated values appear. You can place those rows before valid values or after valid values.
How are ties resolved?
When two calculated values match, the tie breaker decides the next order rule. You can use item name, quantity, priority, or original row order.
Can I use a custom expression?
Yes. Use tokens such as qty, price, cost, discount, tax, priority, and weight. Only arithmetic operators and parentheses are accepted.
Why export CSV and PDF files?
CSV is useful for spreadsheet review. PDF is useful for documentation, approval notes, testing evidence, and sharing ranked results with nontechnical users.
Is this a replacement for form testing?
No. It is a planning and validation aid. Always test the final logic inside your actual form, database session, and user workflow.
