Re: Partial numeric field update in SQL

Hi, Vern:

I agree that in this particular case, the desired action would be to add
100.  My solution was more of a "how to maniuplate a portion of a numeric
field" example than anything else.  What I wrote is not what I'd have done
in THIS case.

Dennis

Result has to be numeric - concatenation is character, so you need to
convert back to numeric. It can be done in recent releases, but why not
keep it simple, as others have suggested? Add 100 * number-of-years

Cheers
