Re: row not deleted but updated (trigger?)

"delete" trigger should return "old".
In your code you return "new" for both: "update" and "delete"

Subject: [SQL] row not deleted but updated (trigger?)

I've:

create or replace function FT1IDX_catalog_brands_update() returns
trigger as $$ begin
if(TG_OP='DELETE') then
update catalog_items set
FT1IDX=GetFTIDX('pg_catalog.english', Code, CodeAlt, ISBN, Name,
Authors, '')
where BrandID=old.BrandID;
else
if(coalesce(new.Name,'')<>coalesce(old.Name,'')) then
update catalog_items set
FT1IDX=GetFTIDX('pg_catalog.english', Code, CodeAlt, ISBN,
Name, Authors, new.Name)
where BrandID=new.BrandID;
end if;
end if;
return new;
end $$ language plpgsql volatile;

create trigger FT1IDX_catalog_brands_update_trigger before update or
delete on catalog_brands for each row execute procedure
FT1IDX_catalog_brands_update();

I do something
update catalog_brands set name='zzz' where brandid=1234;
1 row get updated.

When I do
delete from catalog_brands where brandid=1234; no row get deleted and no
error get reported.

what did I miss?

thanks
