I am in the way to make an SQL server saving transactions. How to make MultipleSaveNewReadings function to perform the best performance for an SQL server saving call without closing/opening connection for each record saving? I don't need to merge the for-next loop into the saving function code but it's ok to get out some of the saving code to be in the for-next calling function.

I want to apply other stored procedure select query on result of first stored procedure.
View 1 RepliesInitially, I have tried to use stored procedure. But I changed my mind and preferred to call sql query in codebase with command text. However, it stills tries to find initially-called stored procedure (which is neither called or exists).I think that it is related caching. But I tried it with different browsers it did not work.What might be the reason?
View 4 RepliesI have heard that saving connection strings and stored procedure names in web.config file of our application is not safe. It is a good practice to store the connection string in a config file rather than as a hard coded string in our code and if we need to change it,then it makes our job easier. how to protect our code in web.config?

I'm trying to decide which is the best way to call a stored procedure.I'm new to ASP.NET MVC and I've been reading a lot about Linq to SQL and Entity Framework, as well as the Repository Pattern. To be honest, I'm having a hard time understanding the real differences between L2S and EF... but I want to make sure that what I'm building within my application is right.
For right now, I need to properly call stored procedures to: a) save some user information and get a response and, b) grab some inforation for a catalog of products.So far, I've created a Linq to SQL .dbml file, selected the sotred procedure from the Server Explorer and dragged that instance into the .dbml. I'm currently calling the Stored Procedure like so:
MyLinqModel _db = new MyLinqModel();
_db.MyStoredProcedure(args);
I know there's got to be more involved... plus I'm doing this within my controller, which I understand to be not a good practice.

This an input to a stored porcedure from a web form. My form consists of a text box, 3 listboxes, and 2 more textboxes and a command button. What I need to happen is when the user clicks the command butto it will submit all of the information on the form to the database table. I have a stored procedure in place and the code-behind. What happens though is that the user enters a value into the textbox and hits the enter key and the application will throw an error that expects the next parameter but of course it isn't there. The listboxes postback to grab the data in connection with the value in the first textbox.Here is the code-behind to the aspx page:

The exact error is that it expects parameter @EquipmentType but it is not supplied. It shouldn't be though because the user has not selected anything from the listbox yet. I thought this was straightforward

I have a form where the user enters their first name, last name, email address etc.. and then they also have the ability to enter 'cottages' that they are interested in viewing (ie. The cottage name, cottage address). The user then needs to be able to 'save' this somewhere and enter another cottage into the same form.
Finally the user will submit the form, and all the user details, and cottage details will be emailed to admin.
