Re:

Have you considered using iDate at www.thinkk400.dk/downloads.htm? You
can could then just do idate(Date_Column,*CYMD) and you would have
your date and if the date if invalid you get back a null.

Hi All

Sorry for all the questions, I'm getting to grips with UDF's in SQL and slowly going round the bend.

I have a UDF that simply accepts a reference number and returns a subset of columns from a transaction file. Within the set of columns I have a number of seven digit date fields, i.e. in the formay CYYMMDD which were being displayed with comma separators. To resolve this I'm using the following formula to convert to a 10 character date in ISO format:

char(date(right(digits(DATE_COLUMN + 19000000), 8) concat '000000'), ISO)

The function creates successfully, however when I run it in interactive SQL I get the following error:

select * from table(GETTRANS('4458499W')) T1

Query cannot be run. See lower level messages.
However, when I run the SQL from the function itself (at end of post) it runs successfully:

select

CKB2CD,
char(date(right(digits(CKHEFD+19000000),8) concat '000000'), ISO),
CKAQCD, CKPEST, CKBIST, CKAZVA, CKPGST, CKBGST, CKPHST, CKB7CD,
char(date(right(digits(CKLWDT+19000000),8) concat '000000'), ISO),
CKBHST,
char(date(right(digits(CKCRDT+19000000),8) concat '000000'), ISO)
from
hplib/htrans
SELECT statement run complete.
Looking at the job log it says that the format of the date is invalid, but I don't understand how that can be the case if the formula works in interactive SQL.

The job log details and function source are shown below. If anyone can shed some light on what the problem is I'd be grateful.

Thanks

Jonathan
