For all questions, provide the answer in the form of a SQL statement, with description before as necessary. Questions NOTES Questions 1 and 2 require you to answer in the form of a SQL statement to create a table and insert data into it. The question and answer is only about the statements to create and put data into the `Occurrence_Exercise` table, however it is recommended that you create the statements to create and insert data into all 3 tables, so that you can test that your statements are correct. Please only provide in your answer the SQL statement for the `Occurrence_Exercise` table. To understand the terminology: • A rep is a number of times you do an attempted weight. • A set is an attempt and in this case, there are 3 attempts (attempt 1, attempt 2, attempt 3). • An attempt contains the weight. So to understand the weight you would lift for a single exercise in the Exercise attempt table you would need to consider the rep multiplied by attempts by the weight. So for a single attempt: e.g. for 9001 rep multiplied by attempts by the weight 8 reps x 3 attempts x 15kg = 360 total kg’s lifted 1. The following Gym application database for weight session recording is as follows.
