Hello,
I wanna ask how I can access array element in array_agg ?
I do select array_agg(ids) from x;
in ids I have int and result is :
array_agg
-------------
{3843,2,3543,33}
I want to access one element or first one direct in sql query like:
select array_agg(ids)[1] from x;
and to receive int value 2
Any hints how I can do it ?
And also for performance did that is good I to do it in SQL or I should
do it in language that I use ? The result in query will return about 2,
3 million rows.
Thank you,
Cheers,
Hristo S.
