Asp.net - Inserting Records From Multiple Computers In The Same Database At The Same Time In SQL Server 2005?
Nov 12, 2010
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.
I am using vb.net and sqlite as database. I am using below scenario to insert multiple records in database using a single query.
INSERT INTO TableName (FirstCol, SecondCol) SELECT 'First' ,1 UNION ALL SELECT 'Second' ,2 UNION ALL SELECT 'Third' ,3 [Code] .....
For less records it is working very well.But when I am inserting about 800 records at a time, executenonquery is throwing the following exception: SQLite error Too many terms in compound SELECT.
i have 3 user roles "ALGEMEEN,OZIS,VERPLEEGKUNDIGE".And I want them added to the database.But when I use the code below it only adds the userrole "ALGEMEEN" and not the other 2.
Dim cmdCheckLidVan As New SqlCommand("SELECT COUNT(*) FROM [Lid van] WHERE [Gebruikers-ID] = @ID AND [Rol-ID] = @RolID", connection) Dim strRolArrCount As Integer Dim strRolArr() As String
I have an Sql server 2005 table called Emploeefl with 2 fields, EmployeeCode and Date of Birth. The data type for the date of birth is Datetime. I have a Date time picker on a vb.net 2005 form called dtDateOfbirth. When I click on the save button I get the error message "Conversion from string 'yyyy/MM/dd' is not valid. Below is the code
Dim newQE_Date As Date newQE_Date = Format(Me.dtDateOfBirth.ToString, "yyyy/MM/dd") 'newQE_Date = String.Format("2008/09/10", "yyyy/MM/dd")
I wish to insert a row into an SQL table a multiple number of times. The only field that will change is the Primary key ID which will update automatically.
To enter the INSERT into a loop seems very inefficient (time). The only other way I can find to do this is build up an array of values and do a multiple INSERT but again this seems very inefficient (memory) when the values will all be identical.
Is there a way of saying insert this row a variable number of times?
The problem is when i insert a first key(dix) records its coying fine. But when i insert the second set of records in is sorting int he table. but when i looked at the dataset by using gridview the recods appears in a right order. but the updated table is somewat sorted order. Is there any possible way to insert the records in the same order in the dataset..
My Problem is that I want to give user a message if the delegate limit has reached for that course.See I have a course where I have MinDelegate and MaxDelegate limit. I want to stop inserting and give user message that "Max Delegate limit has reached can't have more delegates for this course"And below is the insert commmand which is inserting records in my delegate table.
ALTER PROCEDURE [dbo].[uspInsertDelegate] ( @CourseID int,
I typically dont use a dataset in a case of new data insertion to the database. But then again, I will run in a problem the weather the inserting data already exsit in the database. Therefore i need to perform a search first. However, if i follow this it will take slow down the application (if the table has 1 million records). One way i could optmimize this is to load the whole table in to a dataset then the application doesnt have to go to a back end trip nwo it can search inthe dataset. Is this the standard way for inserting records?
I am trying to insert records in an Access database using VB.NET 2008 using the following code:[code]I get this error Syntax error (Missing operator) in query expression when I try to insert any record that has apostrophes in the name.I have tried everything I can think of to get these types of names intserted into the database with no luck.
I created tab controls to seperate the controls till this point everything is OK. but the problem is I can't insert records into database from the tabs controls. but when I enter in all of tabs the insert statment is running.
My program runs with no errors, but the actual .accdb file does not reflect changes when I make them in the running program. Also when I fill in the text boxes and click the "Add New Item" Button, the "ID" text box displays a -1. "ID" is the primary key in my Access Database.

how to share sql database through LAN computers, here what I have done after I did a research.I enabled remote connections for sql server as using both tcp/ip and names pipes.In firewall, I added an exception for sqlservr.exe and sqlbrowser.exe as allowed in the firewall.cplTCp for sql server network configuration is enabled.
Therefore, I connected the sql server database into the vb.net where I chose the wizard for connecting the database as "add new data source"...I selected from there a Microsoft SQL Server (SqlClient). And Then finished the connection of sql server database and vb.net...Therefore, I built the program and its running....In the project properties
Setting tab, I got my connection string :
Data Source=MUSTAFAMUSTAFA;Initial Catalog=CustomerRegister;User ID=sa;Password=123
Or where exactly can the connection string be found?OR that conection string i found the setting tab is enough for other computer to detect my database server?Please here i am stressed about it.So what should I do next...can I publish the program and it will run another machine where database will be looking for my machine...or there other steps I need to do?
After inserting into masterTable it returns an ID. With that ID I want to enter more than one row into a transaction table.
I am using two separate procedures. The problem is, after inserting the record into master, and while inserting into the transaction table, if any interruption occurs I want to abort the corresponding insert of the master table.

I have about 4 different tables with the exact same column names. What I would like to do is select the top 4 records out of all of these tables combined ordered by date (as date is one of the columns that they all share).
I am currently using HDI Membership provider and the design looks as shown below:Now I am trying to create a new user and insert those values into the database as shown below:

I have tried to insert data to SQL Server 2000 database but in vain. I am using Visual Studio 2010. I am using the below code that does not generate any error when i click on the button to insert but instead it inserts NULL as a string in the table for both column. show me how to write a simple application that inserts some data to a database table.Below is the code I have so far managed to write and am using an sql datasource:
I'm using the following code to insert the data in a table and i am getting the error at cmd.executenonquery()....The exception is labelled as SQL exception and the underlying message says "String or binary data would be truncated. The statement has been terminated." [code]
I have three dropdownlist which values are to be inserted in one particular field in the database. But i am new to ASP.

I have ALWAYS used the SQLDataSource to update my records in my SQL Server 2005 database, so i am not really sure how this would be done in normal code. I am using VB.NET but if you are a C# developer and want to show me some code that is more than welcome as well.
I am using ASP.NET 3.5.My user will see a page with 5 Text boxes with their contact details in. Those details I will get from a SQL Server DB and when they go and change the text in the text box and click submit, it must then save the changes.
This is very easy with the SQLDataSource but how can i code this myself?

i've used data set and data reader both but same result. if i use paging then there's will be a problem of search a record on keyup event.
I just learned some basics of multi threading in VB.net recently as I came across processing a large List of records and inserting them into SQL database one by one.
I have code look like this:
Private Sub btnLoadNow_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLoadNow.Click
Dim autoLoad1 As New Thread(AddressOf AutoLoad) autoLoad1.Start()
[CODE]...
Itemlists is a global lists i retrieved from database, everything looks fine to me but when i run this program, I found that the threads are inserting one records 9 times into the database(I have 9 threads in total), which makes me think that maybe i need to specifically assign 1/9 of a list to each thread? Is there another way to do it which doesn't require the splitting of the list, if not , how do i split it then assign?
I am trying my hands on VB.net and is trying out a small application which includes a survey form. The form contains radio buttons and when the respondent clicks on a radiobutton, digit '1' should be placed into the relevant field of the database.I have established a dataset and tried doing it but not sure how to do it because the book (How to program Visual Basic.Net by Dietel) does not teach us that
