I was investigating why a simple query (SELECT DISTINCT srep FROM order
WHERE srep <> "") worked on my machine and yet when deployed, it did NOT
work. Instead of returning several dozen names, it was returning zero.
Now..."why did it work before?" Well, I had changed the query from using
WHERE NOT EMPTY(srep) to what you see at the top of this post.
I figured it was the SET ANSI and confirmed it. I see the original
developer explicitly says in the startup code SET ANSI OFF.
I just can't understand why. This is very old code so I ask those
who've been in the Fox game since 2.x days---was this an advantage when
using some sort of xBase approach? I realize from VFP help that SET
ANSI ON basically makes sure string comparisons are of equal length.
I'm nervous about changing the value at startup because there are
probably areas where the code is COUNTING on it. I see they also have
SET NEAR ON and SET EXACT OFF. I guess code where I'm putting my own
SQL in there (or changing it), I should save their settings, set as I
would normally work (EXACT ON, ANSI ON, NEAR OFF), and then restore
their settings. Kinda like that WorkAreaSave class that I learned (from
Andy/Marcia?) way back when to use a lightweight class in a local
variable to save the current work area when you start a
procedure/function and then it restores it because the LOCAL variable is
released on exit.
