Re: Migration from DB2 to PostgreSQL-TIMESTAMP(arg1,arg1)

[Daniel Cristian Cruz <danielcristian@xxxxxxxxx>]

I've done something weird:

CREATE OR REPLACE FUNCTION "timestamp"(_date date, _time time) RETURNS timestamp AS $$

 SELECT _date + _time;

$$ LANGUAGE sql;

SELECT "timestamp"('2013-01-01'::date, '12:00:00'::time);

It worked, but you will need explict cast and quote the timestamp function name... Many people would not like this.

If you're trying to convert a string to a timestamp as in your first
email, you probably want to_timestamp():

  http://www.postgresql.org/docs/9.2/static/functions-formatting.html

Otherwise, current_timestamp and friends produce the current date & time:

HTH,
