Hi,
I am designing a SQL server backend, MS Access (ADP) frontend
application and I came across an interesting problem.
Lets say I have a table T with the following fields(columns)
[a] (int Not Null, Primary key, Identity auto increment)
[b] (uniqueidentifi er, Allow Nulls)
[c] (text)
When I open the table in datasheet view using Access and type a value
in [c], [a] and [b] get populated automatically. [a] getting filled
with incremental integers is understandable. But, I have not set the
ISRowGUID or a default value for [b] and still it gets popullated with
a random GUID. If I use SQL Server enterprise manager to enter data
into the table T, [b] does not get filled and stays Null. I forgot to
mention that there are no relationships between the tables yet.
Is it MS access that is responsible or is it me? In any case can
something be dont to prevent this? Also should there be something else
in relation to this that I have to look for in the future.
My best

MSSQL itself won't put in a value unless you have a column default or a
trigger on the table, so it seems likely that Access is doing this. You
could use Profiler to see exactly what commands Access sends to the
server when you use the datasheet, but if you want to know why it does
that, then I guess you'll get a better answer in an Access group.

Hi
I have the following problem. I have a SQL Server (2000) Stored Proc that
with 4 parameter (one being @UnlockKey uniqueidentifier OUTPUT). I run it
from Query Analyzer and the @Key parameter is valued. When I run it from
VB.Net it is empty. I tried it with other other datatype and it works fine.
Am I doing something wrong?
Thanks

I have a table that contains articles (as in, newspaper articles, blog
articles, whatever). I need to use a column of type uniqueidentifier
because one of the requirements is that I be able to write the articles
out to XML or import them from XML, and references (as in, "for more
info read this: 2323-232-90934" have to still work after the export and
import).
So as a minimum, the table is going to look like this:

Do I get more scalability if I split my database? The way I calculate
things now, I'll be lucky to get 100,000 records in my Access 2003 mdb.
Here some math:
Max mdb/mde size = 2000 x 1024 = 2,048,000k
Let's say on average each record in the database consumes 15k
2,048,000/15 = 136,533 records

Hello everyone,
This is my first attempt at getting help in this manner. Please
forgive me if this is an inappropriate request.
I suddenly find myself in urgent need of instruction on how to
communicate with a MySQL database table on a web server, from inside
of my company's Access-VBA application. I know VBA pretty well but
have never before needed to do this HTTP/XML/MySQL type functions.

Hi,
I want my application to audit any data changes (update, insert,
delete) made by the users. Rather than have an audit table mirroring
each user table, I'd prefer to have a generic structure which can log
anything. This is what I've come up with:
TABLE: audit_record
*audit_record_id (uniqueidentifier, auto-assign, PK) - unique
idenfiier of the audit record

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
