When processing many records starting from 10,000 System.OutOfMemoryExceptio get the error. There would be some way to handle this type of memory error ?.
ASP.Net SqlBulkCopy- Bulk Insert records and Update existing rows if record exists Exception: Out of Memory Exception C# and VB.Net
I need a way of doing the following:
I receive data in .csv format. I have a some records on a table, so what I need to do is to check if the data I receive exist on the table of records that I need to match against.
If the record exist, then an email/sms should be sent to notify me that the records has been matched and then that record should be flaged that it has been tested so that I don't test it again as the incoming data are saved.
I can't for the life of me remember how to do this and I'm sure someone will answer this pretty quickly. I need to insert or update a record based on if it exists so in the SP I need to do:
SELECT * FROM table1 WHERE LinkedID = @ID Then I need to check if any rows were returned and apply it to an if statement which is where my mind is blocked.
I'm having trouble with an SQL statement. I want to have one statement that checks to see if it a record exists. If it does, then update it and if it doesnt then insert a new one in the server. Here is what I have so far:

View 1 RepliesI want to check if the record is already exists before insert using Ajax ActionLink in Create View. I am getting error 'Object reference not set to an instance of an object.' Here is a code in View :
<div class="editor-label">
<%= Html.LabelFor(model => model.PolicyId) %>
</div>
<div class="editor-field">
<%= Html.TextBoxFor(model => model.PolicyId) %>

else
return JavaScript("alert(' Not Exists');");

I am impoting data from CSV file to my sql server database.
I successfully get data into datatable and using the SqlBulkCopy method to import data into database.
It's working fine.
But i want that if record id is exists then update the record do not insert that record.
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 a form in which when i enter value and upon pressing submit button all the data were shown
on the grid.from where i can edit and update the grid view. in this case i can edit the only particular row. but i want to edit the whole grid and then update it. means bulk edit
Share the code regarding bulk edit and update according to my above mentioned code.

User can Update existing values and can also fill value in empty rows.I need to map these values in my DB table and some of them will be inserted as new rows into the database and existing record will be updated.I need your suggestions, How can I accomplish this scenario with best approach.
View 2 RepliesI have created a datatable with three fields namely TimeTask, TaskItem and Count (count of user) eg; {"12:30AM-01:00AM" , T1 , 3}.
dataTable.Columns.Add("Task Time", typeof(string));
dataTable.Columns.Add("Task", typeof(string));
dataTable.Columns.Add("Count", typeof(int));
dataTable.Rows.Add("12:00AM-12:15AM", "T1", 6);
dataTable.Rows.Add("12:45AM-01:00AM", "T1", 5);
dataTable.Rows.Add("01:00AM-01:15AM", "T1", 1);
dataTable.Rows.Add("01:15AM-01:30AM", "T2", 4);
dataTable.Rows.Add("01:30AM-01:45AM", "T2", 9);
GridView1.DataSource = dataTable;
GridView1.DataBind();
In this there is no task for the TimeTask "12:15AM-12:30AM" and "12:30AM-12:45AM" yet the TimeTask should be inserted as,
TimeTask TaskItem Count
12:00AM-12:15AM T1 6
12:15AM-12:30AM - -
12:30AM-12:45AM - -
12:45AM-01:00AM T1 5
01:00AM-01:15AM T1 1
01:15AM-01:30AM T2 4
01:30AM-01:45AM T2 9
How to chk for the missing rows? Is it possible to dynamically insert rows in an existing DataTable (No DataSource used) in this scenario.
I have a set of dataset with different column retrieved from DB. I need to present the datasets in one GridView (or other ListView etc...) without specifying the column_header. It should present automaticly since the GridView is bind to the DataSet.
In additional, I want this GridView to handle multiple rows edit and update the dataset, idealy, show data in textboxs in initially.How could I set the GridView to edit_model without hardcode column_header and textboxs in 'itemtemplate' or filed.
How could I achieve the bulk edit and update, so that I can assign 'mydataview1.table' to the dataset.

I'm just stuck as I can't work out the best way to do it,
I used to ADO.NET+DataSet many years ago, but now, I need it again. So what I need is to add related rows with tableAdapter.Update method.Here is my code: [Code]....
but I get the "The INSERT statement conflicted with the FOREIGN KEY constraint "FK_Question_Project". The conflict occurred in database "QTracker", table "dbo.Project", column 'ID'. The statement has been terminated." exception at the "qTA.Update(ds);" row. I have seen many examples that do the same, but my code still throws the exception.
I have two roles "Admin" and "Basic". I also have a listview on the web page.
My goal is that to make "Admin" role has the highest privilege to deal with records such as "insert", "update" and "delete".
For the role "Basic", it only can update the records.
