What object in should I use to insert multiple records

Posted on 2010-09-05
Last Modified: 2013-11-10
I want to create a ASP.ney website that will be used as a form for users to input batch files with customer numbers and transactions and amounts.. The users need to be able to paste in 100 customer numbers, transactions and amounts into the form, click a submit button and then be alerted if any of the numbers are invalid.. The info goes into a SQL Server 2008 database table.. So basically they are entering records into a table via a website.. What is the best object to use to do this? Can a datagrid except multiple records? Also, how should I go about alerting the user if the data is not good? For example, if they try to enter a customer and that customer does not exist.... I am a SQL developer for a large Co.. I have and we will use it on our intranet site.. I have done a few simple web pages with SQL attached but I'm not sure the best way to tackle this one..

why you want to do it BATCH?
usually, when you want to use batch, there should be a batch structure behind, this should be the reason for why you use batch.
for example if there is a directory of files. or if there is a .csv file which contains records which should be inserted in database, in these situations you need to use batch of course.
and you can use sql BCP command line to do this, you can use ADO.NET , executenonquery method to run a BCP command to import whole .csv file into sql server.
or also you can use SqlBulkCopy for this purpose.

but if you want to create an form which user enter records manually, one by one, why you need batch operation? why you didn't process every record at the time of entering new line? this way is better when you want to do validations also.

See this code to insert multiple rows from gridview in database
private void StartImport()
       SqlBulkCopy bulkCopy = new SqlBulkCopy("Server=ServerName;Database=test;Trusted_Connection=True;",
    bulkCopy.DestinationTableName = "dest table Name";

     DataTable dt = CreateDataTableFromFile();

private DataTable CreateDataTableFromFile()

       //create a datatable and fill it with the values from the grridview

DataTable dt = new DataTable();
        //add columns to datatable to display in anothre gridview

        for (int i = 0; i < GridView1.Rows.Count; i++)
            Boolean isInsert = false;
            //cell should not be empty
            if (GridView1.Rows[i].Cells[0].Text.Trim() != "")
                isInsert = false;
                isInsert = true;

            if (isInsert == false)
                //check here for other cell validations
            //do the above logic for all cells condtions.

            if (isInsert == true)
                DataRow dr = dt.NewRow();
                //add values to datarow like below
                dr[0] = GridView1.Rows[i].Cells[0].Text;
                dr[0] = GridView1.Rows[i].Cells[1].Text;



        return dt;

ID: 33610902 I have a ASP.Net form and I will attach a gridview.. Should I do something with the SQLdatasource object and in the SQL command part..? Where do I put this looping?  Some more business rules you need to understand.. THe co. wants to use a  ASP.NET web form for users.. These users are phone reps.. They could enter 1 customer at a time or 200.. They have to be able to copy records from another source and paste into this web form.. They have to be able to click a button and see if the customers are valid numbers. I need help doing this using ASP.NET.. Will your solution (dhansmani) work in If so Where do I put your code? I'm new to so I need a little extra 1+1 help:)..DO I have to have the SQLBulk copy part of your code? Please don't get hung up on the bulk part of this exercise. This question is about using a ASP.Net form to enter multiple records at a time ia SQL Server 2008 database and then getting a message letting the users know if specific fields are valid..

If the user is pasting n number of customer numbers, then there should be some delimiter in that data to split the numbers.

Then we can get that numbers in an array and process it one by one.

>>What object in should I use to insert multiple records<<
You could use Table Valued Parameters.  That would seem ideal in your case, as it would avoid the steep penalty you will pay with round trips.   But if performance is not a big deal and you are more comfortable inserting one row at a time, that is fine, too.

Thiis is great SQL answers but what I need first is the ASP.Net question answered. What is the best object to use to do this? Can a datagrid except multiple records?  What object do I use on the ASP.NET web form for allowing users to paste in multiple records?

It is one and the same.  Just a cursory Google search would have told you that.  Here is a link from MSDN:
Table-Valued Parameters in SQL Server 2008 (ADO.NET)

>>What is the best object to use to do this? <<
But to answer your specific question you can use the DataTable, for example.
