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
- The following Gym application database for weight session recording is as follows. Write and run SQL statements for creating the Occurrence_Exercise table.
- Include constraint values for the Condition Column: Heavy, Medium, Light
- Write an SQL statement that will insert the data into Occurrence_Exercise table only.
- Definition of rep stands for repetition.
- Each exercise attempt has the rep number as indicated in the occurrence table.

Create the following queries:
- Find the exercise which contains the maximum total weight lifted
- Show: Exercise, Maximum weight
- Ensure you show captions for each of the columns
- Hint: you would need to consider the number of times the weight is lifted and weight
e.g. rep multiplied by attempt multiplied by the weight
- Find the exercise that the user was not able to complete 3 attempts in, or the exercise that the user has not attempted.
- Show appropriate columns
- List in ascending order exercise type
- Do not show repeated names
- Ensure you show captions for each of the columns
