Karl,

I set up a little test and it failed both ways for me also so here is what I
did

UPDATE hgr0093.date_master
SET testcol = testcol - 00010000
WHERE SUBSTR(DIGITS(testcol),4,1) = '4'

testcol before = 12345678 testcol after - 12335678

Howard, I have tried both ways with the same result.

Thanks for your response!

Hi Group,

I have a file with a 6 digit numeric field. In that field is a YYYYMM

date. I'm trying to update the year to the next year. 2002 to 2003.

My statement is:

UPDATE LIBRARY.FILE

SET SUBSTR(DIGITS(FIELD),4,1) = '3'

WHERE SUBSTR(DIGITS(FIELD),4,1) = '2';

It's barfing on the ( between the first SUBSTR & DIGITS. The error I'm

getting is [SQL0104] Token ( was not valid.

However if I run the following Select statement:

Select * from LIBRARY.FILE Where (SUBSTR(DIGITS(FIELD),4,1)) = '2'

it executes successfully. I could have sworn that I have done updates like

this before! Can someone please explain to me why this doesn't work?

Thanks in advance.
