Hello:
I am new to T-SQL programing, and relativly new to SQL statements in
general, although I have a good understanding of database theory. I'm a
little confused as to the fundamental differences between a view and a
query, or rather, when it is more appropriate to use one vs. the other.
It seems to me that most select queries can be implemented as views, and I
can't see the downside to doing so.

One of the databases has 50 views and when I do a db2look I only get
schema for 40 of them. If I select from the sysviews, I can see all 50
(the text column contains schema for all 10 (missing) views). What's
going on here? Why can't or how can I get the schema for these 10
views.

Thanks.

Hello,
I have a few rather urgent questions that I hope someone can help with (I
need to figure this out prior to a meeting tomorrow.) First, a bit of
background: The company I work for is developing a web-based application,
one part of which involves allowing the user the ability to page through
transaction "history" information.
The _summary_ history table will have the following fields: ServiceName,
Date, User-Ref1, User-Ref2,...

I installed Stinger in my PC (w2k). I need to do a quick compare between DB2
OLAP server and DB2 Cube Views. And I only found DB2 Cube Views version8.1
trial code from IBM website. I didn't want to spend a lot of time on this.
So I installed the Cube Views 8.1, without uninstall ESE V8.2 code first
last Friday. It looks like everything was OK.
But I failed to start DB2 Information Center and DB2 CC today. I've seen

Hello Experts outhere,
may be someone can tell me whats going wrong with my ADOX trial.
I have an Access 2002 database with some tables and queries (views)
The code listed below works well up to the point where I want to add
the new view to the views collection. I get Runtime error 3001 which
is telling me
"Arguments are of wrong type,are out of acceptable range or conflict

Hello,
I am building an application for Windows Forms using. I am new to SQL
Server 'Views'. Are the following correct understanding of their use?
1.) I believe a view can be referenced in a stored procedure something
like this;
Select * from View1
Is that true?

The purpose for my questions is accessing these technologies from
applications. I develop both applications and databases. Working with
Microsoft C#.NET and Microsoft SQL Server 2000 Production and 2005 Test
Environments.
What is the purpose of a view if I can just copy the vode from a view
and put it into a stored procedure?
Should I be accessing views from stored procedures?

Fellow database developers,
I would like to draw on your experience with views. I have a database
that includes many views. Sometimes, views contains other views, and
those views in turn may contain views. In fact, I have some views in
my database that are a product of nested views of up to 6 levels deep!
The reason we did this was.
1. Object-oriented in nature. Makes it easy to work with them.

People are telling me it is bad to put
select * from <atable>
in a view. I better should list all fields of the table inside the
definition of the view.
I dont know exactly why but some say:
A select * from makes sql server does a table scan.

Hello guys!
Bear with me, I am a newbie.
She is the Data Warehouse manager. She has about 50 users to use the
Oracle database from M$ Access via ODBC connection. All those users
have only SELECT privileges on certain tables. I built all the roles
and users for them and they work fine.
Then she asked "Why do YOU let them see all those system tables?",

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:

Overview:
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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
