Question

So I have a manual in this table:

id  lang    header_name        text         
1   uk       Youth Development  It's very important
2   dk       tst                hejsa   
3   uk       tst                hello sir

And I want to make a query that fetches all manual entries for a given language (danish in this case). If for some reason not all 100% of the original manual entries (the UK ones), has been translated I want to get the english entry instead. Is that even possible in table formats such as this?

I guess it would be something with a “group by header_name” of some sorts, but not sure.

Answer 1

Try this, i dont have an SQL and hence this is not tested
The tables t1, t2, t3 refer to the same table use an alias to distinguish them;

select * from t3  
where t3.lang IN ('DK','UK')  
and t3.ID NOT IN  
(select t1.id  
FROM t1,t2  
where t1.header_name = t2.header_name  
AND t2.lang = 'DK'  
AND t1.lang = 'UK'  
)  

Essentially first you need to find the ID that have translation, and then exclude them.
