I'd like to get a record set where I can make comparison result with a relational table:
character_abilities
id ability_id character_id
1 1 43
2 2 43
3 5 43
4 7 43
5 8 43
6 9 43
7 1 75
8 2 75
9 3 75
10 5 75
I would like to get a result like this:
ability_id_1 character_id_1 ability_id_2 character_id_2
1 43 1 75
2 43 2 75
NULL NULL 3 75
5 43 5 75
7 43 NULL NULL
8 43 NULL NULL
9 43 NULL NULL
For this result I thought to do something like this but without success:
SELECT character_1.ability_id AS ability_id_1, character_1.character_id AS character_id_1, character_2.ability_id AS ability_id_2, character_2.character_id AS character_id_2
FROM character_abilities AS character_1
RIGHT JOIN character_abilities AS character_2
ON character_2.character_id = 2 AND character_1.ability_id = character_2.ability_id
WHERE character_1.character_id = 1 AND character_1.ability_id = character_2.ability_id
Unfortunately, this returns only the abilities that each character has in common.
My questions are:
Can I code a query to get each characters props like the result example?
Should I make a query per character and then merge them?
