Question

I’m learning some more SQL, and ran into a “problem”,

I have two tabels like the link below
http://www.sqlfiddle.com/#!2/403d4/1

EDIT:
Since I’m quite retarded now from all SQL-test i have done this weekend, i asked really wrong…
Sorry guys…

What i really wanted:

If i have the requested language, i want to get all the records, and if the requested language is not in the titles-table, i want it to say “” or null…

like if i ask for all records in ‘de’, i want:

1  |  ACHTUNG
2  |  NULL

and if i ask for all the records in ‘en’ i want

1  |  WARNING
2  |  Ambulance

Really sorry for the wrong question.

/*
What i want to do:
I have the ID of a record and the requested language.
If the selected language does not exsists, i want it to take the other language.

like if i have:
language = ‘de’ and id = 1
I want ‘ACHTUNG’,

if i have:
language = ‘de’ and id = 2
i want “Ambulance” since there’s no ‘de’…
*/

How do i do this?

Answer 1

SELECT rec.id, title.name
FROM Records rec
LEFT JOIN Titles title ON title.record_id = rec.id and title.language='de';

SELECT rec.id, title.name
FROM Records rec
LEFT JOIN Titles title ON title.record_id = rec.id and title.language='en';


ID  NAME
1   ACHTUNG
2   (null)

ID  NAME
1   Warning
2   Ambulance
