but row always retrun 0 even procdure do update in database
for 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?
I'm executing an update stored procedure from LINQ to SQL and I need to know the records affected after the update is called. I'm using dbml designer to generate the LINQ code.
View 4 RepliesI am accepting query/queries from user (our support team) in a text box where user can enter only one query or multiple queries. I need to display result of all queries entered in the textbox. If it is SELECT statement then result of that statement in grid which is done. If UPDATE/INSERT/DELETE then total number of rows affected which is also done but if only one UPDATE/INSERT/DELETE statement is entered in the textbox.
If user enters 2 UPDATE statements and then a SELECT statement then how can I get number of rows affected for individual UPDATE statements just like SQL Server Qury Analyzer displays messages in its result pane.
e.g.
(6 row(s) affected) -- first UPDATE statement
(4 row(s) affected) -- second UPDATE statement
(16 row(s) affected) -- for SELECT statement (grid will also be displayed along with these messages).
I tried almost everything, SqlDataSource (returns count of first statement only), SqlCommand.ExecuteNonQuery and DataAdapter.Fill (returns count of last statement only).
I came across a situation where a user selects no of rows from dropdown , depending upon the user input, automatically that no of editable rows should appear to input data...(maximum 8 rows only)

Web 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 ...

I am trying to re-write an existing asp.net website using MVC with Linq to SQL. A page we have is used to insert new contracts and uses usp_contract_insert to insert a new contract into t_contract as well as t_project. On my dbml file i have dragged t_contract on and then I try to drag usp_contract_insert on top of that and I get the error :- Microsoft Visual Studio
One or more selected database objects return a schema that does not match the schema of the target data class. Nothing has been added to the designer. The stored procedure returns the id of the last project which was inserted. I don't quite follow this and unsure how to go about hooking my Controller up using Linq to SQL to call this stored procedure
I am using LINQ to SQL for inserting, updating my DB now i am using stored procedures to do the same,but i dint find any advantages or less code in using stored proc what is the main diff between using stored proc and not using stored proc?

Today is my first day using ASP.NET MVC, and I'm finding it very intriguing. I only just started learning asp.net.
So basically I'm trying to call a procedure from an MSSQL database, and with it I need to send a paramater "PlaceID", which is an integer. This procedure basically just picks out a number of columns from different tables in the database. Here is the Linq to SQL code
The ultimate goal is to be able to retrieve all the information and return it as JSON with a function that will be available for a javascript.
I'm wondering what is the best way to proceed from here. I know I have to create a view, but I'm still unclear exactly on how I can call the procedure and make it store all the information. I could really use some help on this, some code examples would be excellent. I already wrote a C#.net function to convert a datatable to JSON using a stringbuilder, but I get the feeling there is a smarter way to do things.
I am maintaining a sql proc someone else wrote long ago. Basically I have a stored procedure which calls a function. If I try to run the stored procedure, or to make changes to it, and then run it, I am getting an error message which says "An insufficient number of arguments were supplied for the procedure of function dbo.GetRecentComment
This is very odd, because the stored procedure runs successfully when called via the C# code. Yet if it is run within query analyzer with the correct parameters, I get that error message. Here is a little peice of the stored proc which calls the function. And below that is the function which is being called. It appears that the second parameter passed to the function is optional, yet I am not sure. Anyway, here is some of the code from the proc, which calls the function.
SELECT CompletionDate, dbo.GetRecentComment(Request.RequestId) AS Comments -- This line is where the function is called FROM Request
Here is the function which is being called
ALTER FUNCTION [dbo].[GetRecentComment]
(
@RequestId int,
@SmallTag bit -- smalltag appears to be optional.
)
RETURNS VARCHAR(500)

BEGIN
I have this stored procedure which check a collection and according to that return a result.
The problem is I want to check if a number is between 10-20 then do something
How on earth you checking something like that? I know > and < etc.. but checking if a value is a number between 10-20?
i 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?
I have a dropdown list. This is a bound to a column in Table which has around 200 entires.Now when a user clicks on the drop down list I want him to see not more than 10 rows. The rest he should navigate by using scroll bars.
