Inserting Multiple Identical Records Into Sql?
Jan 24, 2012
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?

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 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 added a table to my program and it generated two errors and not it will not build. I have added quite a few tables and this has never happened before. The reeors are:
1. public sub new ' has multiple definitions with identical signatures
2. 'Protected Overrides Sub OnCreateMainForm()' has multiple definitions with identical signatures.
I have deleted the table that I added and tried undoing everything having to do with it but nothing works.

I am designing a test launch tool that I want the user to be able to select a product type from a list and then choose a station type from another list. Depending on what they choose will determine what is run (what is passed out).
The data will look like the following :

10-9890-1 mfgtest1 Progamming.xml config5.conf
10-9890-1 mfgtest2 Configuration.xml config92.conf

I would like to query an Employee by matching First and Last name. Ideally, I'd like to be able to specify that in one EmployeeQueryRq QBFC object.
I think I have a start:
Dim EmployeeQueryRq As IEmployeeQuery
EmployeeQueryRq = requestMsgSet.AppendEmployeeQueryRq()
EmployeeQueryRq.ORListQuery.ListFilter.ORNameFilter.NameFilter.MatchCriterion.SetValue(ENMatchCriterion.mcContains)
EmployeeQueryRq.ORListQuery.ListFilter.ORNameFilter.NameFilter.Name.SetValue(LastName)
Is there any way I can add an additional NameFilter to the same request? Or am I stuck walking a response list for the other criteria (albeit a smaller one limited to containing at least one value)?

I have recently created a disk catalog program for myself, it is working fine. The problem is, when i try to index my 2 TB HDD, the time taken to write 66K rows into sql table is taking a lot of time nearing 30min.
I am using sql client (sdf is the file extension).
Also, i am using two threads to insert data simultaneous saving 50% of time.
I am using vb generated table adapters only.

I need to click an image in a webbrowser from a Windows Form in VS 2010.I can click ordinary links using code such as this one:
Private Sub Button14_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button14.Click
Dim lnk As HtmlElement
For Each lnk In Form2.WebBrowser1.Document.Links
If lnk.InnerText = "the_text_of_the_link" Then
[code]....
When it comes to the second variation of the code I often get the following error message (exception):NullReferenceException was unhandled Object reference not set to an instance of an object.
Basically - how do I tell it to click on it only if there are two separate and unique strings of html code in a html tag?

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?

so now i know i have to use begintransaction to insert records into Access. i've searched for information and it seems that i have to implement Ole.DB and SQL in order for begintransaction to work. My question is, currently i didn't implement any Ole.DB or SQL codes to connect my Access database to Visual Basic.

I've got a form where a user enters data. When the user submits that data, it inserts a record to two separate tables via a dataset. One of the records has no problem being saved into the database (in the table it was put into), but the other record seems to temporarily be in there (according to a third form), because it exists for the duration of the application, but when I exit, and then check the database, it's not there, and it's not shown on the third form when I restart the application again either.

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..
