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.
