The error message you're seeing, "ORA-00911: invalid character", is typically caused by some extraneous, misplaced, or missing character in your SQL statement. Here's a step-by-step guide to fix your SQL statement: 1. Check for any extraneous, misplaced, or missing characters: SQL is very particular about syntax and a misplaced comma, quotation mark, or even a space can cause an error. In your case, the dollar sign before 50 is not valid in SQL. 2. Check the date format: The date format you're using might not be recognized by Oracle SQL. Oracle SQL default date format is 'DD-MON-YY'. Make sure the date you're using matches this format. 3. Check the usage of single and double quotes: SQL uses single quotes around text values and double quotes around column names. If you're using the wrong type of quote, it could cause an error. Here's how your corrected SQL statement might look: ```sql DELETE FROM Orders WHERE (OrderDate 50) OR RestaurantID = 901; ``` This statement will delete all records from the Orders table where the OrderDate is earlier than June 15, 2024 and the Amount is greater than 50, or where the RestaurantID is 901.
