Subject: plpgsql strangeness with select into <variable>

Message-ID: <20030718172452.L54220@spoetnik.xs4all.nl> (raw)
I'm debugging a trigger in plpgsql and for some reason or the "select
into <var>" does not seem to work. Here is an unaltered snippet of my
trigger code:
raise notice ''this id : %'',NEW.id;
select into i_hierarchy_id
hierarchy_id
from link_def LD,
link L,
object_link OL
where OL.id = NEW.id
and L.id = OL.link_id
and LD.id = L.link_def_id;
raise notice ''i_hierarchy_id: %'',i_hierarchy_id;
in the log this results in:
NOTICE: this id : 5265
NOTICE: i_hierarchy_id: <NULL>
but when I perform the query on the command line I do get a result:
select hierarchy_id
from link_def LD,
link L,
object_link OL
where OL.id = 5264
and L.id = OL.link_id
and LD.id = L.link_def_id;
hierarchy_id
--------------
1
(1 row)
i_hierarchy_id is declared as integer and is not used before this code nor
as a column name anywhere.
Does anyone have a clue what is going wrong? I use Postgresql 7.3.3 on
FreeBSD 4.5.
