Nice!!! the article isn't the answer but give me a idea.
In my fisrt solution i was reloading my tbl_user several times. was working bum i was unhappy with because the data was duplicated in many entities.
After read the article i split the entities in other specialized entitites.
here is my new structure:
id as issue_id -- it is my (PK)
id as user_id (PK)
OK, Now I get more entities, but my data isn't duplicate.
Thanks for your help.
PS: if you know more good articles links, fell free to share with me. Thanks a lot.
In short, instead of aliasing the user_id in tbl_issues, load the tlb_users 3 times and alias that user_id to specific id.
id as user_id as author_id
name as author_name
If only the name is needed in the end, use a Map.
