Hi,
I am not sure if this'd help :
1. Are you sure that the sequence and the tablename have the same name ?
[The insert statement is seeing the insert target identifier as a variable]
2. In case you need to run the [INSERT INTO '|| TG_TABLE_NAME ||' SELECT
NEW.* ] statement you could always use EXECUTE to run concatenated strings.
3. Unrelated, but as an advice, I always recommend giving field names while
inserting and intentionally try and and avoid insert statements such as
INSERT INTO xxx SELECT * .

Subject: [SQL] TG_TABLE_NAME as identifier
To: pgsql-sql@postgresql.org
Hello everybody! I'm newbie to plpgsql syntax. Can anyone tell where I'm
getting wrong?
CREATE OR REPLACE FUNCTION tr_audit() RETURNS TRIGGER AS $tr_audit$
BEGIN
IF (TG_OP = 'UPDATE') THEN
...
NEW.id = nextval(TG_TABLE_NAME || '_id_seq'::regclass);
INSERT INTO TG_TABLE_NAME SELECT NEW.*;
ELSIF (TG_OP = 'INSERT') THEN
...
END IF;
RETURN NULL;
END;
$tr_audit$ LANGUAGE 'plpgsql';
returns
ERROR: syntax error at or near "$1"
LINE 1: INSERT INTO $1 SELECT $2 .*
^
QUERY: INSERT INTO $1 SELECT $2 .*
CONTEXT: SQL statement in PL/PgSQL function "tr_audit" near line 8
I tried some variants using INSERT INTO '|| TG_TABLE_NAME ||' SELECT NEW.*
and quote_ident(TG_TABLE_NAME) with no luck! Unfortunately searches on the
Net and old threads on this forum didn't help me.
Hope someone can do this!
Thanks in advance,
Tiziano.
