Re: sql syntax for update

You need an expression that will give you the entire field contents:

update filename set field1 = 'XXXXXXXX' || substr(field1, 9, length(field1) - 8)
where field2 = 'W'

How would i code a sql update statement
to change only the first 8 characters in a 40 byte alpha field?
(i need to substring)
update filename set field1 = 'XXXXXXXX'
where field2 = 'W'

I have 2 diff as/400 based sql books & none show this (which
seems pretty basic).
