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_linkOL 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 OLwhere 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.
