Hello,
I am using pgsql with laravel. I have noticed that PostgreSQL appears to truncate column alias names
after 31 characters.
For example (this is from the psql command-line tool):
SELECT rss_headline_id as abcdefghijklmno pqrstuvwxyz1234 56, title, url
FROM news_rss_headli nes headlines WHERE rss_headline_id = 22833;
NOTICE: identifier "abcdefghijklmn opqrstuvwxyz123 456" will be
truncated to "abcdefghijklmn opqrstuvwxyz123 45"
Granted, having alias names this long may seem a little goofy, but I
am working on an object Persistence Layer that has the capability of
sometimes generating long aliases behind the scenes.
Does anyone know if this is a known limitation to PostgreSQL ? (I
couldn't find any documentation which specifically addresses this
issue) Is there a way to make PostreSQL support longer alias names?
Are there any plans to address this in future version of PostgreSQL?
Or... should I just "suck it up" and fix my code? ;-).
Please suggest me how can i solve this problem.I can not switch my RDBMS from PGSQL to others
Any insights or comments would be appreciated.
Thanks,
Manish Kumar Singh
