Suppose we have a website with 10,000 viewers each second. And we want to insert the viewer's information to the SQL database. So we must insert 10,000 records to the SQL each second. And it may take long time to do.
My question is: How can we decrease this process.
Conseptually what I'm doing is simple, and technically it may even be simple, but I'm still rusty. Here's what I'm trying to do:
I have a webform that allows the user to enter a new record, and in there I have also included a couple FileUpload controls. Upon clicking the "Save" button, I'm saving the details entered into one table (ITEMS), and also inserting the FileUpload details (path, id, upload_user) into another table ATTACHMNTS). Because one ITEM can have many attachments, I needed to split the tables up. So on save, I need to save the ITEM, save the ATTACHMENT, and then also put the ITEM_ID in the ATTACHMENT table. I'm second guessing myself because I think all I'd have to do is after I do the ITEM insert, do a SELECT MAX on the ITEM table and hold the newest (MAX) id in a variable and then use it in the ATTACHMENTS update. I'm not 100% on this because there IS a chance that someone else could save a few milliseconds later and I'll link the wrong ITEM. See my delima?
I have code for inserting a record into the db, it works fine from the admin part of my website but when i put it on the customer side duplicate records are inserted into the db, any ideas? I cant for the life of me see why. I have just also noticed that when i add the claim the first time it adds the duplicate entry, if i press the button again it only adds the entry once, if i refresh the page add the info again, 2 entries, click add again 1 entry?

I do have a details view, which insert data to a database table using SQL Datasource. Now i need the data to be inserted in to 2 tables instead of one.
View 1 RepliesI am using 1 textbox with a Ajax Calendar extender to allow my user's to select a date graphically (exp: 12/15/2009). I have another textbox for the hour and minutes in military time(exp: 15:30). I think i have the code to grab the data from the 2 textbox's and combine them to be inserted into the field (exp: 12/15/2009 15:30). Here is my insert code for the Field:
[Code]....
However unless I make all the fields Nullable the insert fails, on top of that none of the other field that I have selected on the Detailsview Insert or Edit are inserted into there fields. Half of my fields have to be non-null values. So how do I fix this?
I can supply additional vb code and the aspx code if needed.
This is the error I'm getting: Cannot insert the value NULL into column 'Operation_type', table '/GAOSDB.MDF.dbo.BC_Perf_Log'; column does not allow nulls. INSERT fails. The statement has been terminated.'
This is the first non-null column.
I need to get this figured out because I have 30 other web pages that will be utilizing the same approach.
currently I am doing a web application project using 3-tier formating to do out the project. In the grid view is displayed with data retrieved from the database and at the footer there is a row of empty fields for the user to insert records into database and when user clicks on Add New, a new row of empty fields will be populated below.
The database.cs and stored procedure is used to stored the data into the database.

I have a project that I was using Access for but now find I have to change to SQL Express. Well I have no big problem with that but I now find that the SQL Statement I have been using was for OLE and does not work in SQL/Express.

View 1 RepliesI want to do bulk insert,bulk edit,multiple delete records in gridview.
View 1 RepliesI've been wracking my brains for a while. I have a master record that I want to add children to. In a database it's a one to many relationship with a foreign key in the child table.
I have a formview that I want to use to fill in all the master record info, and choose the child info from a dropdownlist, and click an add button, and have the add button add the child info to some control on a page. Then when the user clicks insert, the formview has an ItemInserting EventHandler that will handle all the logic for inserting the master, grabbing its primary Key.
So, I know what to do, I'm just not sure of what control to use, or what memory object etc., that I want to store the child info in until the master record gets created.
I'm sure this has been done a million times, but for all my searching, I couldn't find anything to help me. Does anybody have some advice or can anybody point me to an internet resource where this has been hashed out?
How to add checked records in nested gridview to database in ASP.Net?
View 1 Repliesi have two sqldatasource controls. one i use to display data in textbox's ,filter'd by a select parameter in page behind code. Once checked, i want to copy this data to the other datasource ,by selecting checkbox.Then display this data in detailsview control.
At present the two datasource controls declared , render data to the page simultaneously during pageload. I want to first check data in textbox's from first source, before second datasource is rendered to screen. note, both are filtered by a page variable. i wish to leave the textbox datasource control in situ, as other controls and code depend on it.The other detailsview datasource is my problem?
