Question

I’m having problems with LASTVAL() function. I have a trigger:

CREATE OR REPLACE FUNCTION schema_name.function_name() RETURNS TRIGGER AS
  $BODY$
  DECLARE
    registry_id bigint;
  BEGIN
    INSERT INTO schema_name.table_name(column1, column2) VALUES (value1, value2);
    SELECT LASTVAR() INTO registry_id;
    ...

When the Trigger is fired I get the error:

ERROR:  function lastvar() does not exist
LINE 1: SELECT LASTVAR()
               ^
HINT:  No function matches the given name and argument types. You might need to add explicit type casts.
QUERY:  SELECT LASTVAR()
CONTEXT:  PL/pgSQL function "function_name" line 5 at SQL statement

The table has a PK column with a SEQUENCE as a DEFAULT value:

...
table_name_id bigint NOT NULL DEFAULT nextval('table_name_seq'::regclass),
...

Answer 1

You wrote LASTVAR() not LASTVAL() (R instead of L).
