Question

Given two tables APPLE and ORANGE,

NAME      APPLES
Alice     5
Bob       10
Trudy     1

NAME      ORANGES
Bob       50
Trudy     10
Dick      10

How can I write a JOIN to show the table:

NAME      APPLES      ORANGES
Alice     5           -
Bob       10          50
Trudy     1           10
Dick      -           10

I currently have

SELECT a.NAME, APPLES, ORANGES
FROM APPLE a
JOIN
ORANGE o ON o.NAME = a.NAME

but that only returns the fields that have a value in both APPLE and ORANGE.

Answer 1

SELECT COALESCE(a.NAME, b.NAME) as NAME, APPLES, ORANGES 
FROM APPLE a 
FULL OUTER JOIN ORANGE o ON o.NAME = a.NAME
