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
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.

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?

View 3 Replies View RelatedI 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!

Could someone hit the high points of the benefits of using SQL Server (vs. other databases) with Visual Studio .NET and the .NET Framework.

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
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

I've been researching AWE to determine if we should enable this for our environment.
Currently we have a quad core box with 4 gb of RAM (VMware). OS: Windows 2003 std, SQL Server 2005 std. 3GB is not set but will be as soon as we can perform maintenance on the server.
I have read mixed feedback on AWE, either it works great or grinds you to a hault. I would assume that the grinding to a hault is due to not setting the min/max values correctly or not enabling the lock page in memory setting.
We only have one instance of SQL on the server and this box won't be used for anything else aside from hosting SQL services. We do plan on running SSRS off of this server as well.
1. Will running SSRS and enabling AWE cause me problems? Will I have to reduce the max setting by the SSRS memory usage or will it share and play nice?
2. How do I go about setting the Max value? Should it be less than the physical RAM in the box? Right now its set to the default of 214748364, even if I don't enable AWE should this default value be changed?
3. It seems that even at idle the SQL server holds a lot of memory and the page file grows. If I restart the process in the morning, memory usage in taskmon is at 600mb or so. By the end of the day, its up around 2gb. How can I track down whats causing this, should this even concern me?
4. The lock Page in memory setting worries me. Everything I've read on this seems to give a warning about serious OS and other program support degradation. In some cases to the point where they have to restore the settings on the server before they can bring it back up. What are your thoughts on this.
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 2 Replies View Relatedhi all,
in all my 2.0 learnings and books i keep coming across the page element <asp:sqldatasource>.
I have always (in 1.1) used server side connections and adapters to bind my Sql datasets to any control needed. Now that im learning 2.0 im finding it difficult to understand using control on the page to bind my data. Can someone explain the benefits of using this data source? Ideally i would like to keep my data access layer separate from my presentation layer but i'd really like to understand why this method seems so popular.
thanks in advance,

Hi, I am new to ASP.NET 2.0 and I am trying to use VWB to bind my web site to a SQL Express edition. I used SQLDataSource to specify the .mdf file so I can connect to my tables but when I click on the advanced button to generate the Insert, Update, Delete SQL I find it grayed out and it cannot be clicked. I looked into several tutorials online and I couldn't find the problem, can anyone explain what I am missing or doing wrong? Any suggestion is very appreciated. Thanks

Hi, I want to know when to use an sqlDataSource object because I used to populate for example a listBox control in visual studio net 2003 from AQLK server database by using a connection object, command object, dataAdapter object and a DataSet object. I discovered if I use sqlDataSource object (using visual studio net 2005) ,all I need is to write the connection string and a Select statement as properties for that sqlDataSource, so why to use the above mentioned objects(connection,command,adapter,dataset) while I can access any database in sql server through the use of sqlDataSource?
I appreciate if you can explain to me the difference and when to use an sqlDataSource
thx
How can I update more than one table with one UpdateString in SqlDataSource?
View 5 Replies View RelatedHi,
I have an application w/ n-tier design so I've never used the SqlDataSource up to this point but having to do my own sorting for GridViews is not something I want to keep dealing with. I'd like to take advantage of some of the packaged features too.
My question is: are there any purists out there who opted to use SqlDataSource. If so, what do you think about it? It's nice that SqlDataSource makes things simple but having data classes and dealing w/ exceptions in those classes certainly make an application pretty robust. Should I entertain the idea of using SqlDataSource or stay as a purist and keep doing things the old fashioned way?
