I have not tried this, but it seem that if the column is numeric, the update
value should not be in ticks', note this is just a guess.

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.
