[GENERAL] Select rotate in PostgreSql

2013-03-13 Thread Andre Lopes
Hi all,

I don't know how to ask for this. I need to rotate a Select in
PostgreSql, just like this: http://dpaste.com/1021691/

I can achieve this easily without a procedure?

Best Regards,

yes: that's not rotation but simple aggregation.  look for string_agg

Hi Andre,

If I understood you want to aggregate comments into a single line... is
it? If yes then you can try this:

SELECT article_id, string_agg(comments, ' ') FROM your_table GROUP BY
article_id;

Best regards,
