I wrote the following:
CREATE OR REPLACE FUNCTION escritorio.seq_valor_actual( text)
RETURNS integer AS '
DECLARE
secuencia ALIAS FOR $1;
valor_actual integer := 0;
v_query text;
actual integer;
BEGIN
RAISE NOTICE ''el parametro tiene el siguiente valor %'' ,secuencia;
v_query := ''SELECT last_value FROM '' || quote_ident(secuencia);
RAISE NOTICE ''la sentencia a ejecutar es %'' ,v_query;
FOR actual IN EXECUTE v_query LOOP
valor_actual := actual;
END LOOP;
RETURN valor_actual;
END;
'LANGUAGE 'plpgsql';
And i call:
select seq_valor_actual('s_id_reserva');
The s_id_reserva is a sequence. The error is the following:
WARNING: plpgsql: ERROR during compile of seq_valor_actual near line 12
ERROR: missing .. at end of SQL expression
I think the problem is in the FOR but i see correct all.
Can i help me?
Any idea?
Tahnks....
