Allow Zero Length String Property - 2000 vs 2003

Hello,

I created a table using MS Access 2003 (Which uses Access 2000 format
database), the default value for the attribute, "Allow Zero Length String"
has been changed to Yes.

Can anyone please verify, why it has been done? Is there any way to change
this default.

My two cents: For the past 6 years I am used to seeing the default for
"Allow Zero Length String" to No. Changing all of a sudden to Yes, broke a
whole lot of things. It is extremely frustrating. Why the folks at
Microsoft do not get the concept of backward compatibility. Actually, if you
look at every other relational database, Null value is what goes into a
column, when you try to insert a zero length string. With that in mind, the
defaul of No for the attribute made sense.

I would appreciate the comments.

We've asked as well, but I don't believe we ever got an answer. However, I
don't see why changing the default would break anything. You should always
be checking all your properties to ensure that they're correct before you
start using your tables.

Doug my friend,

I should be checking a lot of things. Why do you think DEFAULT values are
there? They are there, so that people don't have to think about them, if
they don't have to.

You dig?

Regards.

Ash

I can only assume that it was a misguided attempt to 'protect' inexperienced
users from having to deal with Null values. If so, it was of course doomed
to failure, as they will sooner or later have to deal with Null values in
numeric or date fields anyway.

Are you the same person who posted the 'Allow Zero Length String in MS
Access 2002 and 2003' post? If not, be sure to check out that thread if you
haven't already done so.

I'm not sure that I agree. While I understand the arguments
for Null in a database, the fact is that Web Interfaces do
not do Null. Web Interfaces do empty strings. Coercing
Web Interfaces into using Null values is painful, irritating,
and misguided.

So my first guess would be that it was the push towards
Web Interfaces which encouraged MS to set the text property
to allow empty strings.

To a lesser extent, the same is true of any interface other
than the native Access interface, so my second guess would
be that it was part of the historical move from an optimised
database system to the loose collection of standard parts
(office, vba, etc) that is Access today.

Well, if that was the reason, I believe my second point still stands -
changing this property does not solve the problem, as web developers still
have to deal with Null values in numeric and date/time fields.
