Hi!
In SQL 2005 you should use CTE and the new ranking functions; write
<br />
with EmpCTE ( EmpNo, ..., Sal, SalRank ) as (<br />
select EmpNo, ..., Sal, dense_rank() over ( order by Sal desc )<br />
)<br />
select *<br />
from EmpCTE<br />
where SalRank=5;<br />

I have multiple tables that I'm pullng into a C# DataSet.
My first method was to run a query and merge the data I need into one table using the MySQL command.
But here's my problem. I have a shared field x_ID where in one Table A it is null and in Table B it is the primary.
For example:
I have
Table A
Customer_Purchase $5, $4, $3
Customer_ID 1, 2, null
Table B
Customer_ID 1, 2, 3, etc
Customer_Name ...
My return for Who purchased what would only have 2 rows and I'd rather have all three, even though one would have no name in it.
Thanks!

Outer joining is the key:
SELECT b.Customer_ID, b.Customer_Name, a.Customer_Purchase FROM a LEFT JOIN b ON a.Customer_ID = b.Customer_ID
This way you get everything from {a} regardless of what is in {b}

You can write to files and all sorts of other places, but the easiest thing would be to write to a DB table. If you're just debugging, that shouldn't be a problem: just create a table called something like Log, and write to it every time there's a problem.
If you do this in production and there are a lot of problems, the table can fill quickly. It's probably not the best way to do it in a production environment unless you've got a process to clean it out regularly.

use dos commands to log your errors. These dos commands can be executed using xp_cmdshell procedure in SQL Server.
you can also write console applications and run these application using sql server's xp_cmdshell command

Hi,
I have created a MS service that has to connect to my SQL server. But it never does. I use the exact same code that does the exact same thing that the service does, but it is in an application, and it works perfectly. The only difference that I see is the app is run by the user that is logged in but the service runs under SYSTEM. Here is the error the service is getting:
Error Message = ERROR [28000][Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user 'DomainName\SystemName'.
I connect to the ODBC by using: DSN = "DSN Name"
DSN is configured to use the windows account, I also tested it and it works fine.
I am not able to find any pointers, it works as an application, but not as a service? Any solution will be greatly appreciated.
Thanks.

You're having impersonation problems. When your service runs, it runs as a service account (probably the IUSR account if it's a web service). When the application runs, it runs as you, the logged-in user. You have access, the service account doesn't. Your DSN doesn't seem to specify a username or password.
You can do a couple of things:
1. Change the service to run as someone who does have access. If it's a web service this could have consequences on other web services running on the same machine.
2. Explicitly impersonate someone else in your connection string. Put the username and password of someone who does have access after the DSN param in the connection string.
I think there are other more complicated options.

Hello every body,
I have a problem. I've just creating a database application that use the SQL server 2000 engine but I want, when deploying the application, not to install the MS SQL SErver 2000 on the user's machine. how can i do? please help! (sorry for my poor English)

I don't have a clue what is it that you want....
hablas español?
|
|
|
|
|
It mean the user of my application not to know what database engine is using by the application and when installing it, not to use te MS SQL Server CD for installing the database engine!
|
|
|
|
|
Can you not just change the connection string to point to whatever remote server the database is hosted on?
|
|
|
|
|
Thank you. I'd already try the way you propose me and it works. But You know, if you are using a database application such as Sage Saari(Comptabilité) you don't know the database engine used with. that's what I want to do.
|
|
|
|
|
So you're saying that you want to install an application that was written for MSSQL, but not use MSSQL as the database engine?
|

I'm not really getting you here, but i think you might want to look at NHibernate and the DAO design pattern[^] to implement a datalayer on your application that abstracts the actual access to the data.
The client will still need drivers installed on their machines to allow them client access to whatever DB you decide to use...
|
|
|
|
|
if I try to explain: the application will use MS SQL server but I want that, in my install CD, when installing the application, the engine be insatlled with but not Entreprise manager and the other SQL application that I don't need to use my application. Only the engine
|

Is this being installed on the server? I don't think you can redistribute the SQL server engine (without getting a slap from MS) and i have no idea how... If you are installing on client machines, then all they need is the client drivers (ADO/ADO.net), which pretty much all Windows based machines will have.
Apart from that, I don't know and it's Friday afternoon...;P

|
|
|
|
If I'm installing it on the client machine, how can I write the sqConn.ConnectionString? because in it we have only the name of the database and not the full path of the file?
