I agree with David.
I usually create users/rights as structures in the database and use one SQL user/password to access the database.
I do break this rule when security is a one shot item -> You either have full access or you have zero access. In this case I won't go to the trouble to create user/rights structures and just use standard group security on the database.

So then you guys have a table with user ids and a hash for the password that is used for logging into the application and everyone is associated with the one database user id.
That makes the database management piece pretty easy.
So what is the downside to this approach?
Thanks,

The only downside is adding development complexity. You need to manage rights in the application which requires the development of objects manage users and thier rights.

Follow up question:
For desktop applications how do you keep the single user id / password in sync? Alot of people for good reason want to change the supplied default password so hard coding it would be a bad idea.
Is this kind of design pattern covered in a blog, article or book anywhere online?
Thanks,
Koshbert

I work in a closed environment and have no applications in third party hands so changing the db password is not an issue.
Not sure how I would handle an application at other sites. Even encrypting a connection string would require a hardcoded key somewhere along the line.

Hello
I am trying to execute this query:
Create Domain Email
As
Varchar(255) Check (Position('@', Value) > 1)
But the below error will occur:
Unknown object type 'Domain' used in a CREATE, DROP, or ALTER statement.
SignatureNotFoundException

|

..Sql Server does not know about "domains". It hosts tables, records, and you can create things like databases and tables.
How did you expect this to work? Simply throw in the word "domain" and pray that Sql knows what you want?
Computers don't work like that. You learn the computers language if you want things from it, not the other way around.

A DOMAIN in SQL is defined as a set of values for a given attribute! So, of course SqlServer knows something about domains! It just called different!
In SqlServer you use ADD CONSTRAINT to simulate domains.

I saw some samples for creating UDDTs using Create Domain... .
I didn't that word from myself.

..now that I had my rant, let's try and find an answer to your problem. For that, we first need to get a clear description on the problem itself; as is know, I can only guess at what you are trying to do.
- Are you trying to store email-adresses? (creating them is done in another server)
- Create a login? (Google for "create login")
- Something else?

I am trying to create a UDDT. I know how to do it using "Create Type", but I have also saw some query like I have posted.
SignatureNotFoundException

Well, as I know, DOMAIN is not implemented in SqlServer but as a SQL-Language element it's a reserved word.
You can use ADD CONSTRAINT to check the values (google for sql server add constraint, there are lot of samples).

Hi guys, I need to update the data in local database from other database automatically, by date or suggest if there is other way thanks for the help 
|
|
|
|
|
Depends, on the connection, databases used, and your data.
Running a script on a timer is the obvious way, but you might want to take a look into materialized views, or indexed views depending on your flavour of RDBMS.
I don't necessarily recommend it, it depends.

Hi, Im using 2 oracle databases how this could be possibly done?
|
|
|
|
|
Start with creating a database link.
Here's[^] the reference. But as the Oracle reference sucks for learning, I suggest that you google it instead. There's a ton of info on the net.
When you have created the link you should be able to SELECT * FROM mytable@the_other_server.
If this works you can either run a script to update the tables on your server, or create a materialized view that does this automatically.
How to create a materialized view is a much to big subject to answer here, I suggest google again.
Just remember that there are a lot of conditions that needs to be met to get a MV to work.

More info on Advanced Replication[^]
It always helps having the right search term.
You can also find Advanced Replication setup in the Oracle Enterprise Manager under the Data Movement tab.

One option would be to use the Sync Framework[^].

Hi, can I use stored procedure to sync data from other database using DBLink? What are the possible querries that I need to do in this process?

Dunno, I don't know DBLink. Hence, I can also not say if it is an easier or more efficient approach than the Sync Framework which I did recommend.
KingJames06 wrote: What are the possible querries that I need to do in this process?
Depends on your database and it's structure. Syncing is a delicate process, I suggest you take a few days to read everything on the topic that you can find
