Hi, there is an existing application running on a SQL Server database.
Now I have to built a different app, which will have two common tables
with the existing database (Customers, sales)
Is there any benefit (performance mainly) creating the tables for the
new app in a new database? (On the same machine and the same instance)

Hi,
I have a question relating to XML and SQL. My company currently runs a website which allows its clients to log in, view their accounts and transaction history online. The website is totally read only with the exception of changing passwords.
The data is taken from our back office system overnight which runs an oracle 8i database (we cannot like our website to the database due to the agreement we have in place with our software supplier). The data is written to a CSV file which is then converted into XML. The XML file is saved to the webserver and is referenced by the website.
The structure of the website has a relationship where the Client has a Manager who can see their clients accounts, a Branch level that can see all of their Managers and the underlying clients and then finally a company level that sees everything.
We are finding that using XML is causing a real issue in performance and I was wondering if migrating the website to SQL server would improve the performance of the queries etc .
Any advice would be gratefully recieved

I was just wondering what if someone can summurize the benefits between using Access and SQL for an ASP.NET 2.0 website? Can you use an Access database that doesn't have SQL installed on it with ASP.NET?

I find that in Database Exporer in Visual Web Developer, I can specify a DB in two ways, as exemplified here:
Data Connetctions + ke_test_db.mdf + ssftec023-lsqlexpress.master.dbo + ke_test_db2.mdf
Experimentation shows that mdf files that can be put under the "sqlexpress" item (ke_test_db2.mdf in the example) are those that SQL Server Configuration Manager Express knows about, whereas files that I create via adding an item in Solution Exporer appear at the top level (ke_test_db.mdf). My question is, is there any advantage or disadvantage to either architecture? I.e., Is there any advantage to being sure that one's DB files appear under the sqlexpress connection item?
Thanks!

Hi,
I've never really used the SQLDatasource, I usually fill a dataset & use that. When would you use an SQLDatasource? I notice it doesn't return dataviews but I also noticed that you don't need to open the conenction. Any ideas on best practice?
Many thanks
Could someone hit the high points of the benefits of using SQL Server (vs. other databases) with Visual Studio .NET and the .NET Framework.
Thanks
Hey all,
Very simple question from a real n00b: In many of my stored procedures I am repeating a CASE statement where I'm replacing null values with zero, like this:
(CASE WHEN @Field IS NULL THEN 0 ELSE @Field END)
I have many SPs where I have that code repeated literally dozens of times. Is there any performance benefit to creating a function to perform this task and using that instead of the repeated CASE statements? Or am I trying to be too clever?
Thanks!

Hi,
When do we need to have multiple log files for one Database.
What performance counters should I measure before deciding to go for multiple log files.
Any comments / suggestions are welcome.

Hi,
I wonder if there are any drawbacks with NVarChar(max) contra e.g. NVarChar(40) when it comes to performance and amount of storage used?
Are there other arguments to use e.g. NVarChar(40) than that you have more control of how long the strings are when you set the upper limit?
I'm using Sql Server 2005.

Hi
How can I find out which edition of SQL Server is running on my server ?
Also what would be the difference in terms of features between standard edition and enterprise edition ?
Thanks
Vijay
I have read over the feature set and I really don't see a huge reasons to jump on the bus. There are a few niceties like IP enhancements, cluster enhancements and maybe bitlocker for the backup drive. Am I missing something?

View 3 Replies View RelatedHow to create a database in MS SQLserver 2005 express edition.
Pleae help me to get started.I have learned some SQL commands.
But i want to execute those in SQLserver 2005.But i don't know the procedure for creating a database.please help me on this.
Im creating a sample database for purposes of keeping track of employee's jobs + billing codes for that job. currently they just use an excel spreadsheet to keep track of billing.
Question 1:
What would be the easiest way for the manager to enter billing codes? Billing codes are numbers like 956, 958, 805 and they co-relate to prices for each billing code.
1. I want the manager to enter the billing code and have the sql database find out how much that code is and add them up daily. This would prevent the manager from having to input prices and billing codes, and extra step.
Any links on the above topic would be helpful. I'm not looking for anyone to spoon feed me code just point me in the right direction. Im relatively new to sql having only a class of sql @ ITT.
Heres the way I have the db tables laid out currently.
employee table
employee_id
technumber
fname
lname
address
workphone
homephone
trucknumber
officelocation
employeejobs table
employee_id
jobs_id
jobs table
jobs_id
codes
date
timeframe
city
hours table
hours_id
employee_id

Any info would be much appreciated, Im going to go find a sql book now ;).

View 1 Replies View RelatedI am using the SQLEXPRESS database, and connect from to locations:

ASP.NET web application.
whenever I start the windows service I get the error: Cannot open user default database. Login failed.
so I am going to visual studio and close the connection. then I close the web browser, and the windows service succeed connect to database.
but then, after windows service is connected, I open the web browser application and fails to login because the login system using the same database of windows service, and since the connection is being used by windows service, login is impossible.
Do you know how I can allow 2 connections at the same time for the same database?
what are the risks to do that? and how do I handle this risks.

Hi,
I have a SQL Server 2005 Express database dbase.mdf which I cannot access. It works fine in VWD and the development server using the following connection string: String connectionString = "Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\dbase.mdf;Integrated Security=True;User Instance=True"But when the site is not on the development server but on IIS, I get a SqlException saying "User does not have permission to perform this action." when I execute the connection.Open() command. I find it extremely frustrating that something which works in the development server fails on the real server. Can anyone help me with this? Do I have to change my connection string, or perhaps set some permissions...I have already given the IUSR_MACHINENAME account and the ASPNET account full access to dbase.mdf. Surely this must be an issue that lots of people deal with... How do other people manage to log to access databases? Any help would be much appreciated. Thanks,P1000
