Hi every one,
Well I’m building a desktop application for an organization in C# 2.0 and Sql Server 2000 and I was wondering abt putting some sort of restriction so that the user doesn’t access the data in the tables from the Enterprise Manager. So first, plz tell me if this is a good idea or not. Well I think at least some users should not be able to access the tables directly. So how can we put this restriction?
Thanks in advance,
Rocky

User accounts. Each user connected with the relevant username and password, or via windows authentication (which logs them in with their windows account). You can restrict access based on the account or role.

Hello everyone,
I’m working on Fuzzy lookup within SSIS package. It is done with the fixed similariry and looking up fields. Right now, we are trying to move to use dynamic varibles for Similarity and looking up fields. That means the similarity value and looking up field values are passed by variables and are assigned values from outside of the ssis package. If anyone has an idea on how to do it, could you please give me a clue. I’m really apprecite your any suggestion in advance.

Hello,
I am in search of the .NET Framework 1.x and 2.0 and 3.0 class
library maps and ADO.NET class library maps to hang/pin to my cube at
work and also at home. I believe that helps understand more about the
Framework and ADO.NET objects and class libraries. Also if some thing
is presented in a pictorial (grapihical) representation I guess I can
learn more than reading whole lot of stuff.
So is there a place on the net or any company that offers this kind of
to buy or down load?
Any inputs or help me finding on this is greately appreciated.
Thanks in advance,

I would think it would make more sense to only give access to the application to access the sql database and remove all other access. So if you application is using a sqluser name and password for its connection. Only give that user access.
If that is not an option. Then another possibility is to make sure all of your database access for you application happens through stored procedures. In which case the user would not need select access to any of the tables only execute rights on the stored procedures.
Hope that helps.

Thank you Ben,
it's good idea and if I distribute database file than the stored procedures are enclosed in database files and with rights too?
I read about encrypting, but it is only for column not all database.
I hope, that it is last question.

When you distribute the database you can set up the user rights to the tables. Unfortunately, if they are the ones that installed sql server then they would have an SA account which would allow them to change their access and read their tables.
I think if you can not control your users access to your database, you will have trouble short of encrypting each column which would affect performace.
I have seen other programs like Microsoft great plains, where all of there access is through stored procedures which are encrypted. Then all the tables have names that are like IV10001. That way it is not easy for users to understand what the table is. Still if your users can or will have SA access to your database they will be able to decrypt the storedprocedures.
Sorry I couldn't be more help.

If they are unauthorised then Enterprise Manager wont let them in.

Hi All,
How can we lock and unlock the database
Manoj Bisht
|
|
|
|

What do you mean by that? You can lock bits of the database just by selecting rows. The database will temporarily lock those rows so that the SELECT can get a clean result set out.

Hi guys, I've got this problem, hope someone can help me out.
I've written and application and it works fine on my computer and i can connect to SQL through a Text file
connection string in the Text box : Data Source= NameOfMyDataSource;Initial Catalog= DataBaseName ;Integrated Security=True
As I said, it works fine on my computer but NOT on other computers !!!
I installed my application on another computer and also installed SQL server, then attached my database and it works fine, but when i run my progran and enter ID and Pass get this error !
System.Data.SqlClient.SqlException: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
Please help me out !!!
Thanx in advance

It seems that someone else (our web company) are able to login to it and the server is external to them as well. Any ideas?
Can you connect if you specify the IP address & port number instead of the host name? Is there a firewall in the way?

Satips.

By default, SQL Server blocks remote access. To get round this, log into SQL Server Configuration Manager and make sure that you have enabled Named Pipes. Then, go into the Surface Area Configuration Tool and make sure it's set for Local and/or remote connections for Named Pipes. Now, restart the SQL Server instance.

Try changing Integrated Security=true to Integrated Security=SSPI.

Hey everyone! I'm a little stumped on a problem with some SQL code that I'm writing, so I was hoping someone might be able to offer some advice.
I have a varchar column on a table in which I record the id_keys of another table. Sometimes multiple id_keys are entered into the column, which we format as: 1; 2; 3, with each id_key seperated from the previous one by a semicolon with a space (; ). What I'm trying to do is to write an update statement that will pull the numeric values of the id_keys out of the varchar string, and then match them up to the id_keys of the first table. This is the basic statement I've got so far:
UPDATE TABLE1
SET column1 = a.column1,
column2 = a.column2
FROM TABLE2 a
WHERE TABLE1.id_key = (
SELECT column3
FROM TABLE2)
Column3 is the column that would have the varchar string containing the id_keys of TABLE1. Obviously, simply doing a SELECT statement on column3 won't be sufficient, but I'm not sure how to write my SQL code to give me the data I need. I suspect that I'll also have to convert the data back to numeric from varchar, but I haven't got that far yet.
Any thoughts or suggestions? Thanks everyone!

What is the necessity of storing data like this. Why don't you store the data in multiple rows ? Then your problem will be solved.
If you still want to use the current method, I suggest you to append the same type of string in other table where you are going to check. I think that can solve your problem.

Well, the tables that I'm trying to do this on are part of a commericial sales database, not one that I've developed myself. On the table that I'm saving the id_keys in, a row is only inserted when a customer makes a purchase (the id's represent vouchers that can be redeemed as part of the purchase). As a result, a customer might redeem multiple vouchers as part of a single sale. I would use more columns, but the table only allows me to use up to 10 custom defined columns, all of which I have data feeding into.
As far as appending the same type of string in another table, I'm not quite sure I follow. Could you elaborate? (I don't actually have any training with sql, so I'm figuring this out as I go, with a little aid from Microsoft's "Querying Microsoft SQL Server 2000" book.) Thanks!

If these tables become large, you're really going to have some performance issues stripping out these string values all the time - you really should consider denormalising these keys...
