Perhaps it's a bad example of the use of ltrim(rtrim()). Why would you use ltrim(rtrim (anything)) on a single character field? Even though the PoMast.fStatus field is 20 characters, I get the same result set when I use select PoMast.fPoNo from PoMast where ltrim(rtrim(PoMast.fStatus)) = 'open' as I do when using select PoMast.fPoNo from PoMast where Pomast.fStatus = 'open' Not sure what the purpose of this post is.

Even though the PoMast.fStatus field is 20 characters, I get the same result set when I use

select PoMast.fPoNo
from PoMast
where ltrim(rtrim(PoMast.fStatus)) = ‘open’

as I do when using

select PoMast.fPoNo
from PoMast
where Pomast.fStatus = ‘open’
