Hi all,
I want to build an application in which I have an XML files which contains the connection string and credentials to connect to multiple databases. I want to connect to these databases and run a stored procedure on these database and close the connection. Can anyone guide how to proceed on this. I want to have front end which will fetch the data from the XML file for database connection, make the connection, run the stored procedure and Close the connection. Any Idea How can this be implemented.

What have you done so far?
What exactly is the problem? Can't you read an XML file or connect to a database or execute a stored procedure?

Are you using .Net? Siunce you didn't specify, I'm going to respond as if you are.
You should ask google about the connection strings section of the web.config. The web.config is an xml file that is already prepared with the necessary reading functionality, and the connection strings section is built to store connection strings. This is a built in feature of ASP.NET
Also ask him about ADO.Net. Ado.NET is a library for connecting to a database. There are many articles on CP about connecting to databases from .NET.
This really belongs in a programming board corresponding to the language you are going to write the application in.

Hey everybody!
I created a table-value function, so I will be able to perform a SELECT with parameters:
SELECT * FROM get_user (1) -- returns user with userID "1"
The problem is that I can't find a way to call this function from C++ using ADO (not ADO.Net). 
I've been searching the net for 2 days now, and I'm pretty close to give up... 
Thanks in advance!!!

Have you tried actually running "SELECT * FROM get_user(1)" from an ADO command? It should work fine - although most people tend to use stored procedures for this type of thing.

Are you getting an error of some sort? I can't say I can help with the C++ part, but your query probably won't even work in QueryAnalyzer from the looks of it. UDFs and TVFs must be schema-qualified, like this:
SELECT * FROM dbo.get_user(1)
So what you're missing is "dbo."
I hope that helps.

HI all,
I am facing a problem that occurs with a specific database "X" only and not with the others in the SqlSever 2000.
Actually, while running an Insert/Update statement in the query analyzer for db X, it happens that the execution of the Insert/Update query is taking too much time the 1st time only. whereas for a Select query, I'm not facing this problem.
can anyone help?
Regards,

Without any further detail such as tables defs and code its hard to say. The first time a query is run it will always be a little slow as the optimiser has to work out the query plan. Have you looked at the query plan to see what is happening? If the update statment is auto generated often the unique primary key is being updated which slows things considerably.
Hope this helps

Actually this is happening for only one db and for an insert query as well as for update , whereas it was normal before.And i'm running this query on a table which has no relations with other tables that's why it sounds weird for me! The time taken the 1st time to be executed is 30-60sec!
so if a user wants to insert a new record for this table, it will give him a timeout expired.
so to resolve this problem temporarily, I run an insert query in the query analyzer (wich will take a long time) and by then the user will able to insert or update normally(bcoz data pages are in memory buffer) and so the query will run faster.
But this is not a final issue, so any other suggestion?
Thx in advance

And your question is?
You need to provide more than just the source code. I'm guessing there is something wrong with it. So what is wrong with it? What should it do? What does it do? What error are you getting? Where is the error occurring?

hello everyone , iam sorry for being far from this forum from along time but it is out of my hands . ok !
now there is a problem or a difficulty for me to completely design this database , using this case study
"we have 50 materials available for students to study.
each term , every student has the ability to sign only 3 materials only of his choice from the above 50 materials , suppose that this student failed in one of them so the next term will only sign two with the material he failed in so the total is also 3 materials in each term , and there are some materials if he failed in them render him from taking some other materials which are related to the materials he failed in , explain further .
suppose that student failed in material B and material G is built in knowledge upon material B thus he can't choose material G except if he succeeded in B first .
so i am suppose to design this database for student result examination i don't know really how the database could be designed ???
any help please .

I am starting on a new project and see how powerful LINQ is. One thing I need to know before we begin is if there will be any problems using LINQ to run queries against a Sun (Oracle) Database server. Any input is welcome.
Thanks!

LINQ does not currently work directly with Oracle. However, you can use LINQ to Datasets if that is of any help.

I would like to specify a default value for a column that increments along with the row number/identity column.
i.e. Insert tbl_User (some_data) VALUES (test)
resulting in
User_id first_name last_name some_data
1 Test User 1 test
I was sure there was something like @@row_number, but searching on msdn/google has turned up nothing useful so far...
Any suggestions?
Thanks,
Al

Set your default value to something like
'Test' + CAST(DATEPART(second, GETDATE()) AS VARCHAR)
or for more randomness
'Test' + CAST(DATEPART(second, GETDATE()) AS VARCHAR) + CAST(DATEPART(ms, GETDATE()) AS VARCHAR)<br />
You'll get fairly random data, not entirely unique though.

use sonia
create table stud(roll int identity(10,2),name varchar)
insert into stud values('A')
insert into stud values('B')
select * from stud
**IDENTITY(10,2) --> 10 is the initial value
2 is the number by which the value is to be incremented.
U can also decrement the value.

Hallo
We have set up Replication in several locations the SQL Server Enterprise Edition which is the Publisher is running on a different location while the Subscribers are running SQL express Edition which use Windows Synchronization as it does not have agents. The problem is users entering Passwords each and every time the Synchronization starts is there a way to enter the database only once and save it to the client Computers?

I'm using SQL server 7. Unfortunetly, the database I'm working with was not designed very well to restrict the date format input by the user. I need to change a table's column [IncidentDate] from a format of mm/dd/yyyy (12/25/2008) to a format of ddmmmyy (25DEC08). There are over 3,000 entries within this column that have a mixture of these two formats. I'm not sure exactly how I would accomplish this task. I tried using SQL Server Enterprise Manager's export/import tool to place the data into an Excel spreadsheet, manipulate the dates, and then import back into the database. I come close to resolving my issue, but I always get an error in the import function.
Any help is appreciated.
