Merging two rows to one while replacing null values

Question

Let\'s say I\'ve got the following database table

Name | Nickname | ID
----------------------
Joe    Joey       14
Joe    null       14

Now

Answer 1

AFAIK, the question is not clear.so i am making some assumptions over here. your output has the first and 3rd columns for both the rows as same. Only the 2nd field is different.

so u can simply write a select quest

select one.name,two.nick_name,one.id from 
(select name,id from your_tb group by name,id) one,
your_tb two 
where two.nickname is not NULL 
and two.name=one.name 
and two.id=one.id;

may be we can tune this but i am not good in tuning sql squeries,but this is the way i suppose u need.
