i guess an array is also ok. must been something like:
fn_get_subsamples(IN sample_numbers[] integer) ??
how would a query then look like?
SELECT * FROM sample WHERE sample_number IN ( fn_get_subsamples(1,2,3,4)
) ??

hello pgsql fans out there,
i've already created a function that returns a list of IDs of all sub-samples based on a given sample ID. this works fine. now i like to extend this function so that it can receive a list of sample IDs. e.g.:
fn_get_subsamples(IN sample_numbers SETOF integer)
There's no such animal as a function that accepts a set. You could pass
it an array of integers instead. Or maybe just call it more than once.
