Question

For purposes of the example, I have 2 tables – a couples table and a persons table:

Persons Table
ID PERSON
1 Bob
2 Frank
3 Sally
4 Jane

Couples Table
ID HUSBAND WIFE
1  2  3
2  1  4

Can I write a single query statement to select from both tables and have it join in such a way that the query result will produce:

Couple 1 = Frank and Sally
Couple 2 = Bob and Jane

Thanks

Answer 1

SELECT Couples.ID, Husband.PERSON, Wife.PERSON
  FROM Couples
    INNER JOIN Persons AS Husband ON Couples.HUSBAND=Husband.ID
    INNER JOIN Persons AS Wife ON Couples.WIFE=Wife.ID

Just a note, though – not every marriage is husband/wife these days. Spouse 1 & Spouse 2 might be more future-proof.
