View 1 RepliesBulkinsert From CSV Into Db (C#) -> Max Number Of Rows In A Web Application?
Apr 28, 2010Web application - C#, .Net, SQL 2k5.I recently used bulkinsert on an other application and I thought I would like to give it a try.
I am going to receive a CSV file with 1000 rows, which will most likely add 500 000 (that is five hundred thousand) records in the database.I don't have any idea yet about this huge amount if it's going to work out well. I am afraid that it will time out.
I didn't do any testing yet, but I am pretty sure it would time out eventually.
Is there a way to make it not time out (I don't know ... split the bulkinsert into 1000 pieces :D) or I should try to do something like BCP, with a SQL job ...

How Do Display Total Number Of Rows In A Table Into A Label
Oct 6, 2010i use sql server 2005 and Visual Studio 2008.
I am using asp.ne and vb.net for my website.
i have a table with number of rows 50,000.
i want to display the number of rows at my table in a Label when the page is on load.
so can u give me the code or the hint?
my second question is.
my table has around 50,000 items.
and i have a search box, it look like this
str= select * from mytable where item='car'
the item Car is located in my table in row number of 45,000.
i guess when i search from the table where the item is car, then it will search row by rows, then as the number of rows become huge, it will be so late to find the result.
so is there any method how to search from table with good speed of searching?

View 5 RepliesSetting Label Text To Number Of Rows With JQuery?
Feb 18, 2011This is my code but nothing happens.
$(document).ready(function() {
var totalRows = $("#<%=GridView3.ClientID %> tr").length;
document.getElementById('Label6').InnerHTML = totalRows;
});
this is what i ended up using
var rqnum = $("#<%=GridView3.ClientID %> tr").length - 1;
document.getElementById('rqnum').innerHTML = rqnum;
var oknum = $("#<%=GridView4.ClientID %> tr").length - 1;
document.getElementById('oknum').innerHTML = oknum;
var xlnum = $("#<%=GridView5.ClientID %> tr").length - 1;
document.getElementById('xlnum').innerHTML = xlnum;
var dynum = $("#<%=datalist1.ClientID %> tr").length / 3;
document.getElementById('dynum').innerHTML = dynum;
this way it subtracts the header, however, how can i make it so if it is 0 dont subtract the -1 because i dont want negatives

View 3 RepliesHow To Enforce A Certain Number Or Range Of Affected Rows In SQL Server Or C#
Feb 17, 2011for some SQL queries I know the expected number of rows that must be affected by UPDATE, DELETE or INSERT statements. It could be a number such as 1 or a range such as 0-1 or 1-2 etc.
What is the best way to enforce that this is the number of affected rows and that otherwise an exception is thrown?
Also, can I limit the number of rows affected for UPDATE/DELETE/INSERT to say 1 row and otherwise get an exception?

View 5 RepliesDataSource Controls :: SQL Query Return Incorrect Number Of Rows?
Mar 29, 2010I am working on a small project. I ran the query below to get the maximum userid and increase it by 1 to create a new userid. However, when I run the query, it does not display the values that I enter into the database using insert statement. For example, if I open the table called login, I can see there are three records. If Irun the select statement, it only return one record which is the one that I enter manually when I first created the table. If I run the same select statement and give it a user id that I created, it returns the correct result.

Forms Data Controls :: Return Number Of Rows In A Dataset?
Jan 14, 2010I'm using a table adapter to perform my queries. I'm sure I'm missing something really easy, but I can't figure out how to return the number of rows returned from a query to a dataset used for a GridView.Basically, I want to display a message "No records exist for your selection" by testing for ReturnedRows = 0.
Excerpt of C# code:

new handoutDSTableAdapters.handoutTableAdapter();
gv_Handout.DataSource = handoutsAdapter.GetDataByDoctor(Int32.Parse(ddl_MD.SelectedValue));
gv_Handout.DataBind();

I now want to count the number of returned rows so that I can say:IF rows_returned = 1 then login else deny
I think you get the idea.P.S. I know this is not the most secure method of login but I do not want to use the ASP.NET configuration manager as I like to understand what is happening. I am starting off very simple and I shall work up from there.
