Related to another topic I just posted, I wanted to discuss ways to optimize
the validation of very large (>100MB) XML documents.
First, I have no idea if something like this already exists; it may even be
the typical implementation for all I know.
At any rate, it occurs to me that the set of business rules that need to be
validated against an XML document represent a limited set of nodes at any
given time (while parsing through the...

Hi all,
I am doing a project for university whereby i have to implement a
simple database related to a frozen foods company. I am having some
trouble though creating a validation rule for one of my fields. I
have a table called "Product" and two of the fields included in this

validation rule so that the Cost Price is always less than the Retail
Price. I have tried...

I've got a validation rule that says something like =xx or xxx or zzzz.
Though I may not have described it well it does work fine and that is really
not my question.
Here's what I'd like to do. Let's say that I choose zzzz, I'd like for
a particular control (or text box) in my form to become required. At other
times, if xx or xxx is inputed it would not be required. Is this possible?
Thanks, and as always, further explanatiions...

Hello all,
I have a quick question regarding an MS Access database I'm creating.
In the entity "ORDER", I have the attributes "Order Date" and
"Delivery Date". I need to create a validation rule here. The
delivery date must come after the order date.
Would anyone be able/willing to help?

I want to set a validation rule that will not allow me to input data in field1 in TableA that is not found in TableB under field2. Basically, Table B under field 2 has the following row entries: Apple, Pear, Lemon, Orange. When I input data in field 1 for Table A I want it to give me an error message if try and input Watermelon (since Watermelon doesn't exist anywhere in Table2.) If anyone could help me out with this, it would be much...

Hi guys,
So I'm editing an existing database (Access 2003), and I need a bit of help in making a validation rule.
My table has many fields, 3 of which are indexed (location, number & revision)
Each of these 3 fields can have duplicates (Same location can exist for multiple items, same number can exist for multiple items, and same revision can exist for multiple items).
However, all 3 fields cannot be the same in multiple records (Ex.....

Hi guys,
I would like to setup a validation rule for a database in microsoft
access that restricts data entry so that a certain field can only be
filled in if another field has a specific answer (that is selected via
a drop down list).
Example
Field1 - options are "In" or "Out"
Field2 - options are "Join" or "Not Joining"

I'm surprised I couldnt find a question about this here so guess I better ask.
I have a form with two date fields. and . Obviously, Enddate cannot predate Startdate field so I decided to do a validation rule for both fields.
I selected the startdate field and inserted <= along with Validation text.
Now, the strange thing is that no matter what date I select in the StartDate field, the validation rule fires and the Validation Text pops...

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
