It is recommended to use Windows Authentication to access the SQL Server. It may be possible that the person who set up SQL Server on your machine did that. Why not speak to them about how they set up SQL Server on your machine? It would seem the most sensible first step.

Hello,
It's surely a stupid question, but I have a problem:
I have two tables like A with field´s number and amount and a table B with number and name.
Now I will have a join like 'SELECT ... form A, B where A.number = B.number - but I need the summary of 'amount', even if there does not exist an entry in table B. Is this possible with SQL??
Maiy thanks, Gerhard

It sounds like you are talking about a JOIN. If you want all of the data from the "left" table even if it doesn't match your SQL would look something like this:
"SELECT amount FROM A LEFT JOIN B ON A.number=B.number"
Or maybe this site could explain it better:

Very many thanks for your reply. It's a wonderful help for me. But I have a secon qustion . The solution is great and it works, but can I do it with more than one table?
Someting like: A.numnber1, A.number2, A,amount WHERE A.number1 = B.number AND A.number2 = C.number'.
I have a table with accounting-sentences and there are accounting-numbers, cost-center-numbers and so on. And I want to give the numbers a name (which are stored in different tabels) without loosing the amount of 'value' in table 'accounting-sentences'
Many thanks again, your help was wonderful

Hello Kschuler,
I found how to do it with more tables. I tried a little bit with the enterprise manager. But i would not have been able to find it without your help. So again many thanks ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif) , ciao, Gerhard

We are using XML to pump data into a SQ: Server 2005 database. We pass an XML document into a stored procedure, the stored procedures chunks out the data and inserts it into the appropriate tables. Fine. Works great, easy to maintain, excelent performance. Here's the problem. One of the columns we are pushing data into is of data type text and the .value fuction of the XML node does not support conversion of a node's data to the 'text' data type. For example:
CREATE PROCEDURE as MyProcedure @myData xml<br />
BEGIN<br />
INSERT INTO MyTable (FirstName, LastName, Notes)<br />
SELECT<br />
MyNode.value('FirstName[1]','varchar(50)'),<br />
MyNode.value('LastName[1]','varchar(100)'),<br />
MyNode.value('Notes[1]','text')<br />
FROM @myData.Notes('Person') as R(MyNode)<br />
END
The problem is with the notes field. The cast to the data type text fails with the following error:
The data type 'text' used in the VALUE method is invalid.
The workaround thus far has been to use varchar(8000), but it will result in truncation if the data is too long.
Any ideas?

Try varchar(MAX) instead of text.

Hello all,
I'm continuing to write a fairly complex application. I have a fair amount of data that I would like to store with the application that will include a lot of lookup data that is both fairly relational and somewhat large (several megs in size). The lookup data will be regenerated periodically. If the amount of data were a little smaller (and a little less in need of strict enforcement of relationships), I'd probably just store it all in XML files. Because of this, I've opted to go with a database to store this data. In addition to the main client application, there are a couple of small apps that will be used to retrieve information to stuff into the database. The database would actually be read-only from the client app and would only be writable from the information gathering applications.
What I'd like to do is set up a database project and have it point to a local database file. I want to source control my scripts for the database and be able to quickly create a copy of the database on a different development machine. It would be even better if I could just move the database around as a file as part of my project. I basically want all the benefits of MSDE / SQL Express with the portability (in the sense of being able to move the files around) of Access.
What would you suggest?

Use MSDE/Sql Express and employ "detatch database" /"attach database" to copy the database around:
I.e. Detach the master copy of the database. copy the .mdf file (attach will create a new .ldf).
Copy the file to the new server, and on that server "attach" the database, editing the locations for the log and data files as needed. Re-attach the master to your development server and keep working.
The same technique can be used to distribute the final version.

I'm having a problem getting my application to connect with an instance of MSDE over the network. I installed MSDE using the following parameters.
INSTANCENAME=MyInstance DISABLENETWORKPROTOCOLS=0 SAPWD=password SECURITYMODE=SQL
I have searched everywhere for an answer to my problem and I have followed all the solutions I can find with no luck. I have made sure the port numbers line up, I have enabled networking protocols, and turned off firewalls.
I can connect to SQL Server just fine over the same network but not to an instanse of MSDE.
SOMEONE HELP PLEASE!!!!!!!!!!!!

I'm working on a web app written in vb.net. I recently added a column in the table 'clients'. I had to manually update the .xsd schema file. After doing that, modifying the client info via the web interface stopped working. To fix the problem, in the 'clients_modify' sproc I had to remove some of the where clause criteria (the where clause was previously written to match on all fields). The match on all fields is what is currently in production, and it works. Question - why did I have to remove comparison on 8 of the 25 fields in order for the update to work after the dataset modification?

Without knowing more about the structure of your database that may be difficult to answer.
A more pertinent question might be why are you trying to match on all these columns when matching on the primary key would do the same job?

I realize matching on the primary key is sufficient. I came into this app after it had been in production for over a year. This is just one of the many things I have to fix. 
On a side note, I ran into a similar issue about a month ago. I updated a dataset and a corresponding sproc stopped working. I'm not sure if it's due to the poor initial design of the app or if it's a known issue in .net architecture. My original question was leaning towards the latter. Thanks for taking time to think about it.

From what you've said I think that it is much more likely to be the "poor initial design" that is the problem.
