Hello everyone. I hope someone can help me with this. I have 3
columns called EMPLOYEE_TEST, TEST_QA and EMPLOYEE_TEST_ANSWER.
The TEST_QA table contains the following:
TEST_QA_ID | PROC_TEST_ID | TEST_QA_QUESTION | TEST_QA_CORRECT
-----------+--------------+------------------+----------------- 3| 1|First Question | 5 4| 2|Second Question | 1 5| 1|Third Question | 2 6| 3|Fourth Question | 1 7| 3|Fifth Question | 5 8| 3|Sixth Question | 2 9| 3|Seventh Question | 3
The EMPLOYEE_TEST table contains the following:
EMPLOYEE_ID | EMPLOYEE_TEST_ID
------------+------------------
3| 7
The EMPLOYEE_TEST_ANSWER table contains the following:
EMPLOYEE_TEST_ID | TEST_QA_ID | TEST_QA_CORRECT
-----------------+------------+----------------- 7| 9| 5 7| 8| 2 7| 6| 1
From these three tables I can see that the employe with ID = 3 has answered 3 questions and two of them are correct. What I would like to be able to do is to represent this in a view (if possible)
EMPLOYEE_ID | EMPLOYEE_TEST_ID | TOTAL_ANSWERS | CORRECT | WRONG
------------+------------------+---------------+---------+-------
3| 7| 3| 2| 1
Thank you in advance...
