I have a table called 'students' with the appropriate fields. There is another table named parents_prof which contains records of common professions. The tables are related through the 'ID_parents_prof' of the 'parents_prof' table to two fields on the table 'students', thus 'students.father_prof' and 'students.mother_prof'.
1st question) Is that possible? Is it possible to create a relation between the key field of one table to two different fields of another table? Is it a good practice?
I did this because I want to build a query which checks for both fields together, meaning I want Access to return a record if the appropriate profession is in either field of mother's or father's profession.
Access cannot represent the above graphical, so I had to enter the
in the SQL formula.
2nd question) Is the above proper query, according to the rules?

Code:
SELECT students.surname, students.name, students.father_name, students.father_prof, students.mother_name, students.mother_prof
FROM parents_prof INNER JOIN students ON (parents_prof.ID_parents_prof = students.mother_prof) OR (parents_prof.ID_parents_prof = students.father_prof)
GROUP BY students.surname, students.name, students.father_prof, students.mother_prof, parents_prof.parents_prof
HAVING (((parents_prof.parents_prof) Like "*" & [enter profession] & "*"));Access cannot represent the above graphical, so I had to enter the
Code:
OR (parents_prof.ID_parents_prof = students.father_prof)in the SQL formula.
