Time Type

Hi there,

I'm trying to do some as following and I couldn't:
select '00:01:00'::time + '00:10:00'::time
ERROR:  operator is not unique: time without time zone + time without time zone at character 127
HINT:  Could not choose a best candidate operator. You might need to add explicit type casts.

Postgres version: 8.3.3

Anyone knows anything?

Regards,

Rafael Domiciano

What exactly are you hoping for? I do not think that adding two
times makes sense. Maybe you want one to be an interval?

I'm doing the following SQL and i getting error:

SELECT
  flc.cod_fila_negociacao,
  1 AS ordem
FROM cbrflcfila_cobranca flc
WHERE
  flc.num_prioridade = 0 AND
  flc.hor_distribuicao +
    ( SELECT pac.num_tempo_espera_urgente
      FROM cbrpacparametro_cobranca pac
    )
  <= CURRENT_TIME

I need to get a time to do a condition.
I couldn't do the SQL

you try to do something like this

select '00:01'::time + interval '10 minutes'
