I've probably asked this before, but I can't remember the answer!
One can use the DECIMAL function to convert a date to a decimal.
For instance
values decimal(current _date)
returns 20080528.
Is there an easy way to convert the decimal value back to a date?
I can't use DATE(<decimal-value>) because it expects the decimal value to be
the number of days since Jan 1, 0001.
I'm sure I could write a function to do what I need, but I don't want to
waste my time if it already exists.
DB2/LUW 9.5.
Thanks,

This groups archive (in Google) shows a nice solution (amongst others) by
Tonkuma:
DATE(TRANSLATE( 'ABCD-EF-GH',DIGITS(MYDA TE),'ABCDEFGH') )
[where MYDATE is your decimal-date-field].
The thread was called "Convert DECIMAL to DATE" and was started on 20060308

In DB2 9.5 you can also use TIMESTAMP_FORMA T() (aka TO_DATE) after
converting the beast to a string.

Thanks Serge and 'Boss'.
This is what I came up with:
CREATE FUNCTION date_from_decim al (dec_date DECIMAL(8))
RETURNS DATE
SPECIFIC date_from_decim al8
LANGUAGE SQL
CONTAINS SQL
NO EXTERNAL ACTION
DETERMINISTIC
RETURN DATE(TIMESTAMP_ FORMAT(DIGITS(d ec_date),'YYYYM MDD'));
Works like a charm.
Still think that something like it should be built in to DB2, but perhaps
it's not that common...

I do have another sort of related question...
Is there a way to automatically issue a SET PATH statement whenever a user
connects?
I want to place the date_from_decim al function in a particular schema that
is not named after any particular user (CREATE FUNCTION
fb_func.date_fr om_decimal), but I also want to allow any user to invoke it
without needing to use the schema qualifier. I know that I can have each
application issue a SET PATH statement prior to invoking the function (SET
PATH = fb_func, CURRENT PATH), but it would be nice to have DB2 do this
automatically.
Thanks,
Frank

If the users are connecting via CLP, I don't know of another way other
than setting it each time. If they're connecting via other means, you
could try setting the current (function) path via the cli.ini. Also--
again depending on how users are connecting--the application server/
ORM layer/JDBC layer may have its own ini file that you could put the
entry (or its equivalent) in.

We'll be connecting either from JDBC (via Websphere) and from host DRDA

Frank,
In re: WebSphere, I just spoke to one of our administrators, who gave
me some information that might be helpful to you: You'll want to set
the currentFunction Path Custom Property within your Data Source, which
is itself within the JDBC Providers link in the Resources area of the
WS Admin Console.
