Uppercase and Lowercase

Hello
 
In my PostgreSQL database i have records inserted in Uppercase.
For example: VIA SENATO
 
What i want is to change them to "Via Senato". Ofcourse i'm looking for a automatico way. I wrote this code update registro1 set pa_indirizzo = upper(substr(pa_indirizzo, 1, 1)) && lower(substr(pa_indirizzo, 2, length(pa_indirizzo) - 1)) But it doesn't work.
 
When i run only update registro1 set pa_indirizzo = upper(substr(pa_indirizzo, 1, 1)) It gets me the first letter and when i run
update registro1 set pa_indirizzo = lower(substr(pa_indirizzo, 2, length(pa_indirizzo) - 1)) I get from the second letter to the last. But when i join them them don't work..
 
 
Anyone got any idea??
 
Thanks

Have a look at the initcap() function.

Of course it does. That's what you ask your query to do. You only used the wrong operator for string concatenation, which is why it didn't seem to work. But your query will not do this for each word in a field. For that you need a function or regular expressions. I suggest you try
select initcap(pa_indirizzo) from ..

Please always reply to pgsql-sql@postgresql.org and not to the senders email address.

initcap() does what you want.

Robert is right of course. You can eg use a trigger to do that...
 
I haven't tested, but I guess something like this would do what you want whenever you insert records in your table
 
CREATE OR REPLACE FUNCTION "public"."func_change_case" () RETURNS trigger AS
$body$
BEGIN
    NEW.pa_indirizzo := initcap(NEW.pa_indirizzo);
    RETURN NEW;
END;
$body$
LANGUAGE 'plpgsql' VOLATILE CALLED ON NULL INPUT SECURITY INVOKER;
 
CREATE TRIGGER "TRIG_yourtablename" BEFORE INSERT
ON "public"."yourtablename" FOR EACH ROW
EXECUTE PROCEDURE "public"."func_change_case"();
 


>>> "Hiltibidal, Robert" <Robert.Hiltibidal@argushealth.com> 2007-02-19 16:55 >>>

Exactly. Since its only a select group of words this query applies to its better to correct for this before the information goes into the database.
