Hi!
Table source contains integer column. Its values should be passed to
function for selecting data from other table.
I tried
CREATE OR REPLACE FUNCTION
public.TestAddAssetTransactions(dokumnrs int[])
RETURNS int AS
$BODY$
with i1 as (
INSERT INTO bilkaib (dokumnr)
select dokumnr from dok where dokumnr in (select * from
unnest(dokumnrs))
returning *
)
select count(*) from i1;
$BODY$ language sql;
create temp table bilkaib (dokumnr int ) on commit drop;
create temp table dok (dokumnr serial primary key ) on commit drop;
create temp table source (dokumnr int ) on commit drop;
insert into source values (1),(2);
select TestAddAssetTransactions( (select ARRAY[dokumnr] from
source)::int[] )
but got error
> ERROR: more than one row returned by a subquery used as an expression
How to pass set of integers to function? Should temp table with fixed
name used or is there better solution?
Using Postgresql 12+
