I want to generate 30,000 cards and each card must be duplicate check with database. In my card, there are 2 things. Serial No and CardID. If any card already exists then I generate another card id but with the same serial no.
So how faster way I can generate 30,000 card with duplicate check? Which one I have made application, it takes about 25 minutes to insert.

I need to insert large amount of data into SqlServer 2008. My project is based on linq-to-sql.
I process csv file with 100.000 rows. Each row is mapped to Order object. Order contains also collection of Category and Code objects. I need to map each row to object in order to validate it.
Then I need to insert all these objects into database.
List<Order> orders = Import("test.csv");
db.Orders.InsertAllOnSubmit(orders);
db.SubmitChanges();
OR
foreach(Order order in orders)
db.Orders.InsertOnSubmit(order);
db.SubmitChanges();
Both ways are slow. Is there any workaround? I may use other approach than l2sql for this task.
I read about SqlBulkCopy class - would it handle inserting child entities as well?
I have an excel sheet that contains around 30,000 rows and 18 colmns. These no of rows and columns may increase in future. I need to read all these records from excel sheet and insert into a table in sql database. For reading the excel book I am using Oledbconnections. The possible solutions I have known as per my knowledge, to insert the data are
1. To insert one record at a time which makes 30,000 database hits. How will this affect the performance?
2. To use liked servers - bu this is not working for me.I do not have database permissions to use linked servers. So, the only option i have is the first one.
I have a project that will be assigned to me soon whereby I need to develop a survey which needs to support 40,000 users approximately. Now we are thinking of doing a staged approach so not all users are on the server at any one point of time. Probably splitting it so we can serve at least a few thousand of users...
I dont have much experience of how I can ensure to serve those levels of users on a server and how to manage this so I am after some advice?
From my understanding I need to do some stress testing on a server and obviously I need some figures i.e. average size of request, average size of response and content of response.
- Do I have to build the database and add records in to see what size is a typical survey row?
- Do I have to build the survey in .NET i.e. by adding controls etc and seeing what size is the page?
- The survey shouldnt be too instensive processing wise, it will be adding information into a backend sql database...
i need to insert multiple rows at a time into database table(sqlserver) from datatable or gridview. Actually iam looping through the rows of gridview and inserting each row.

View 3 RepliesAs I know, we can use INSERT INTO (....) SELECT FROM command to select data from one table and can insert into another table.

I have a web portal designed in ASP.NET in which we ask customers to enter the data. On the click of submit button all i have done is, just read the data and called a stored procedure which inserts that into a table. There seems to be a problem in SQL Server 2005 while inserting the data from multiple computers at the same time. We have tested in our lab with three computers, result is that we get the data inserted successfully in only one machine and on the other two machines we get error on page. I have used transactions in the stored procedure and also tried setting the isolation levels to READ_UNCOMMITTED, SERIALIZABLE and SNAPSHOT. Nothing seems to work properly.

In my program, I need update a filed to the database. The field is for a pdf file content. I know, maybe I should save the pdf file to the local file system, and save the file path to the SQL. but, right now, it is the file content saved to the SQL.
from my program, it loads the file which is input by user. I use File.ReadAllBytes. Then, run the stored procedure on the SQL server, and use the bytes[] as parameter, to insert the file to the SQL. it works fine when file size is small. However, as file size becomes larger, say 200MB, sometimes, it pops out of memory exception.
So, I'm thinking, maybe I can load parts of the file, say 1MB a time, then update the database, then loop. so, this way, no matter how large the file is, it should not have any problem.
my question is: is there a standard way to do this? so, I should not save file content to the SQL at all? shoudl save file in file system, save the file path to sql only? or there are other way to deal with this?

I have an application which imports data from csv to sql server 2005. It is taking long time to import data from csv to sql server 2005. it has a timer. on tick of timer, I am checking if current rown in csv exists in database. If it exists, It is not added to sql server otherwise, It is added that row to sql server 2005. Also, In page load, It checks on each tick, whether user is logged in or not. it adds value to log file that user is logged in. How can I optimize this ?
