Re: [GENERAL] selecting data from subquery in same order

You may use something like this in a stored function:

DECLARE
    a INTEGER[];
BEGIN
    a := '{2341548, 2325251, 2333130, 2015421,2073536, 2252374, 2273219, 2350850, 2367318, 2032977, 2032849}';
    select * from users where id = any(a) order by idx(a, id);
END;

Or in the plain SQL:

    select * from users where id = any(a) order by idx('{2341548, 2325251, 2333130, 2015421,2073536, 2252374, 2273219, 2350850, 2367318, 2032977, 2032849}', id);

Note that it is pretty fast only if the array contains not too much elements (e.g. 20). Do not use for large arrays!

hi
if i execute this statement:

select * from users where id in (2341548, 2325251, 2333130, 2015421,
2073536, 2252374, 2273219, 2350850, 2367318, 2032977, 2032849, )

the order of rows obtained is random.

is there anyway i can get the rows in the same order as the ids in
subquery? or is there a different statement i can use?
thanks!
