DataSource Controls :: How To Access Database Once With Big Resultset Or Access Multiple Times On The Fly

Jun 17, 2010

I have a situation where I am accessing a database multiple times and I'm wondering if it is necessary.

I have a GridView with a template column with a hyperlink to "Get Results" and on the RowDataBound event I have it check the batch number against the database and see if results exist and then if they don't, hide the link.

So when viewing the page if there is 20 rows in the gridview it is effectively doing 20 queries.

I was wondering if it is a better idea to query the database once with all "batches" and load it into a datatable, then on the RowDataBound event query the datatable. The only issue I see with this is there is currently 40,000 batches and grows daily.

Access A Database Table Multiple Times For Every Request?

Mar 16, 2011

A class in my ASP.NET website needs to access a database table multiple times for every request. The database table should rarely change, if ever. Maybe a couple times a month.

In the static constructor of the class, the table is fetched from the DB and cached in a static local variable. Whenever the class needs to access the table, then, it just uses the cached, static version.

My question concerns the lifespan of this cached, static version of the table.

I understand that it's fetched the first time the class is instantiated or a static method in the class is used. But how often does this occur on the web server? What if the table changes and we want to reset this static version of the table?

Basically, I'm wondering, is this table fetched once and then only refetched each time I restart IIS? What, with regard to the site and IIS, will trigger this static class to reset, causing the static table to be refetched?

Access :: IIS_WPG Write/modify Access To The Folder Where MS-Access Database Is Located - Insert An Error Pop-up?

Feb 17, 2010

Is there anything missing in IIS 6.0 that prevents me from (Insert into table) using MS-Access?

Explain: The application works fine under Visual Studio 2008 IDE the insert into table works fine with no error, Also I tested with hosting provider and works fine with no problem. but now I have published the same exact app in a dedicated server windows 2003 with
IIS 6.0 .NET framework 2.0 with latest service pack I gave IIS_WPG write/modify access to the folder where MS-Access database is located and database but at the time of insert an error pop-up. I need to install in the Server or settings in the IIS to recognize my MS-Access db is it some office runtime that I am missing. (BTW I am using OLEDB connection string in my C# )

Using System.Data.OleDb;

I can retrieve data off of it with no problem but when I try to insert is when it fails I thought the problem was Access Rights but I do not think is the case.

DataSource Controls :: Write MVC Application To Access Multiple Data Stores?

Mar 17, 2010

I would like to write an MVC application that accesses multiple data stores (SQL Server, MySQL, Cloud based, etc.).Most of the examples I see use LINQ to SQL for their data access but I read somewhere that LINQ only supports SQL Server - it may have been an old post.I was wondering what the best way to access these different data stores would be. Can I use the Data Access Application Block from MVC to access these data stores?

DataSource Controls :: Locking Down Database Access For Production?

Mar 12, 2010

In the development environment, in SSMSE > MyDatabase > Security > MyUser > Database role membership I have checked db_owner to allow me to build the database.

Now I am copying the database to the production environment I would like to lock the security down tightly. In the past (with classic ASP applications) I have only checked db_datawriter and db_datareader and, in Securables, checked Execute Grant on the stored procedures.

In Database > Securables I add my stored procedures and check Execute/Grant for each of them and click OK. When I return to the securables page the stored procedures are no longer listed.

I have noticed that nothing is listed in Effective Permissions and I think it should list Execute. If this is the problem, how do I add Execute to the Effective Permissions list?

DataSource Controls :: Select Statement Pulling Multiple Times From Same Row

Jan 5, 2010


I have a select statement that is supposed to be filling grid with information from an income table. It's only supposed to pull if the income is from the current fiscal year or is less than 1 year old. Currently, what it does is pull multiples of rows and also rows from past income years but only if there is a mixture. For instance, if a person has income from 2005 and 2010 what it will show is this

Income 2005
Income 2005
Income 2010
Income 2010
Income 2010

Does anyone know what I've done wrong? BTW, those results are exact, old income is shown twice, current is shown 3X

Queue Access To The Database To Avoid Multiple Cache Items?

Jun 7, 2010

I have a music related ASP.NET web site which caches a lot of static information from the database on the first request.Sometimes, the application is reset and cache is cleared while the application is on heavy load and then all http requests go to the database to retrieve that static data and cache it for other requests.

How can I ensure that only one request go to the database and cache the results, so that other request simply read that info from cache and not needlessly retrieve the same info over and over again.Can I use thread locking? For example, can I do something like lock(this) { db access here }?
