detaching a db in sql 6
I was just wondering of how to detach a database in sqlserver 6? is
it the transerfer tool'
MTIA,
GrawshaNow, this was a whole ago, but...
That would be the DROP DATABASE command. SQL Server didn't actually removed the disk devices in the
old architecture when you did DROP DATABASE (you created those devices explicitly and a device can
be shared among several databases).
The hard part is to do "attach", which involves DISK REINIT and DISK REFIT, something you really
only use for emergency recovery.
I suggest you save yourself *a lot* of trouble and do DUMP and LOAD (backup/(restore). And even that
is a lot harder in the old architecture, so make sure you read up on the subject if needed.

to another server will DUMP the database
and use LOAD Database in the destination server to Restore the database.
In SQL 6.0 there is no concept of files, all were devices and database will
reside above the devices.

Designing Database Diagramm
i am looking for a tool to design den model of a database.
i took a look at powerdesigner, embacadero..
which one do you prefer to design the model.
i am using SQL SERVER 2005.
Message posted via webservertalk.com
http://www.webservertalk.com/Uwe/Forum...amming/200602/1HI,
There are quite a few out there,
Erwin,
Visio,
Case Studio
Datanamics Dezign
All depends on the indivisual, the project, what you like, what you want to
do.
I use both case studio and dezign, because it fits my needs and I can afford
it.

designer wanted
I'm looking for (preferably free) a tool that is useful in graphical
representation of DB (something like Oracle Designer). Could you give me
some hints where to find one?
Thanx
Yaro
Visio is pretty good for any type of UML design as well as E-R Diagramming.
It can even generate classes for you as well as the SQL needed to create the
objects.
Its' relatively inexpensive as far as designers go.

One key feature is the ability to create a database or at least tables

diagram relect in the tables and relationships.

Design Tool and Security roles
I have 2005 SP1 and after adding the new users to the Server in Studio, I go to the Design tool and create a new role, I add the user and check the following: process database and read definition.
I then go to Cell Data Tab and select Test Cube Secuirty; when asked if I want to deploy the cube I say "yes". after I deploy it I get the following message: "You are browing the cube using credential of the following roles: Sales" then I get the message below that
"Connection can not be made. Ensure the server is running" and
No connection could be made because the target server actively refused it.
I am connected to the cube so its running, remote connection are allowed, I already connected, just attempting to define and test other roles? Is there an issue with Test cube security? any suggestions?
Try to re-connect your Cube browser after deploying the solution.

What worries me is that you say "adding the new users to the Server in Studio, I go to the Design tool and create a new role".
You should'nt go and manage your security in different places. If you to add uses in SQL Management Studio, next time you deploy your solution, Role memebership will get overwritten. Try to make all the changes in BI Dev Studio.
I would also recommend you upgrde your Analysis Services to SP2.

Edward,
Maybe I miscommunicated that, I do make them in the design tool, I keep all my roles in the BI tool but I started to try to test them there before I deploy them and I can't test them that was my error. When I go to CELL Data and select "test Cube Security" I get the error.
Thank you,
Janet

Hi Edward,
I don't know how to browse the cube under a different role in SQL Managment Studio.
I think we have moved onto a different direction, let me try to explain a little better.
All my roles actually work when the user accesses the cube the defect or error is I can't "test the role" in BI Development tool. If I select a role that I know actully works and attempt to do the test from I go to the "Cell Data" tab and click on Test Cube Security using a role that I know allows the user access I get this message " your are browing a cube using the following role: process and read" - connection can not be made insure the server is running. But if i check with the users in that role, all the users in that role can access the cube.
So my problem is not that the role is not allowing access, its that Test Cube Security gives me a bogus error, because that role can access and browse the cube.
Thank you,
Janet
|||Just wondering does the "test cube security" actually work in the BI tool for everyone but me? is anyone else having this problem?

Design Question
I have the following design issue which I am unsure how to solve.
Here's the key information:
I am writing a tool which will send emails/SMS to registered users. The
registered user data will be stored in one database (we'll call it
DB1). No changes can be made to DB1. All information related to the
tool will be stored in a different database (we'll call it DB2). This
will include the following tables (among others):
- "Sent Email" table to store which user (from DB1) received what email
- "User" table to store individuals who have permission to login to the
tool
- "Email Template" table to store email templates
- "Email Template Log" table to record which user created/edited the
template
My specific problem is how to model these relationships in DB2. Will
DB2 contain a "User Look Up" table which stores the ID (PK) of the user
from DB1? Therefore my "Sent Email" table will have a FK from this look
up table? In addition if the scenario was that I needed to record an
attribute "Don't send me messages" would this be stored on the look up
table as well?
Thanks for any help in advance.

I guess you'll need a Users table in DB2. What you won't be able to do is
create a foreign key on it that references DB1. Cross-database constraints
aren't supported. You could create a view in DB2 that references the Users
table in DB1.

Design Pane.
Where is it located?
R
Personally, I use Query Analyzer and write all of my select statements. =
I find this easier, faster, more powerful, and more flexible than a =
poorly designed multi pane query design "tool." I have total control =
over the sql that is generated within Query Analyzer and I have the =

With that said, one way that I know of to access the query designer is =
to navigate to a table via Enterprise Manager, Right click | Open Table =

Deserialize xml data from sql 2005
In a nutshell, I have a schema. I have used .Net 2.0's xsd tool to create classes from this schema.
This schema is also tied to a XML column in my database server. So far so good.
However, when I go to deserialize the xml data stored in the database server I'm getting inconsistent results. Namely the differences in the following queries:
SELECT LoanXML.query('declare namespace MISMO="http://mrgdev.local/mismo/";//MISMO:LOAN')
FROM Loans
WHERE Loans.InternalID = @.LoanID
returns something completely different from:
SELECT LoanXML from Loans where InternalID = @.LoanID
The difference is that the first query throws xsi:nil=true into EVERY SINGLE NODE. Whereas the second one doesn't.
When we go to deserialize, then the nodes aren't converting into objects even though they are properly filled out...
I'd just chuck the .query syntax, except for a little problem where I'm trying to return just the node(s) I want instead of the whole thing.
Is there anyone else using xml deserialization with SQL 05?<xs:schema

Is there some way to get around this?
