Use `RAISE NOTICE` to print error messages. ```sql EXCEPTION WHEN OTHERS THEN RAISE NOTICE 'Error in procedure %: %', SQLERRM; RETURN 'F'; -- Failure indicator ``` This prints errors directly to TOAD's Output window. ## Step 2: Test with Real Data (Not Just Theoretical Inputs) <img src={require('./img/29fd1871-e017-4b34-a907-5538b18e76c0.jpg').default} alt="Illustration of a blue database icon with a circular synchronization symbol, representing database backup, restore, or synchronization." width="550" height="450"/> <br/> Use actual data, including edge cases like invalid IDs or `NULL` values, to properly debug your [stored procedure](https://www.w3schools.com/sql/sql_stored_procedures.asp). ## Step 3: Get Interactive with TOAD's Debugger TOAD provides a powerful interactive debugger: - **Open SQL Editor**: Load your stored procedure. - **Set Breakpoints**: Click on line numbers where issues might exist. - **Start Debugging**: Right-click the procedure name and select `Debug`. - **Watch Variables**: Monitor values in real time in the `Watch` window. ## Step 4: Check Execution Plan For performance issues, use TOAD's `Explain Plan` feature: ```sql EXPLAIN PLAN FOR SELECT * FROM users WHERE status = 'Active'; SELECT * FROM TABLE(DBMS_XPLAN.DISPLAY); ``` This helps identify bottlenecks and optimize queries. ## Step 5: Logs, Logs, and More Logs Ensure important details are logged for future debugging: ```sql DBMS_OUTPUT.PUT_LINE('Procedure started for user: ' || user_id); ``` ## Step 6: Have a Code Review (or Just Ask Google) If stuck, seek help from **Google**, **Stack Overflow**, or a colleague for fresh perspectives. ## TL;DR: Debugging Like a Boss <img src={require('./img/32935.jpg').default} alt="Isometric illustration of a computer setup with a cloud database, security icons, and a tablet on a futuristic purple-themed desk, representing cloud computing and data management." width="550" height="450"/> <br/> - Use `RAISE NOTICE` to print errors. - Test with **real data**. - Step through the code using **TOAD Debugger**. - Analyze the **execution plan** for slow queries. - Log errors for **detailed tracking**. - **Google it** (really, it works!). Debugging stored procedures may not be fun, but with these tips, you'll solve issues faster and with less frustration.
