View 3 RepliesI 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 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'm getting an exception error when trying to insert a record to a SQL table in VB.NET. Following is my insert command.
cmd.CommandText = "INSERT INTO RunnerDB VALUES ('" & txtLast.Text & "', '" & txtFirst.Text & "', '" & txtMiddle.Text & "', '" & txtAddr1.Text & "', '" & txtAddr2.Text & "', '" & txtCity.Text & "', '" & cmbState.SelectedValue & "', '" & Integer.Parse(txtZip.Text)

I am getting the error on the cmd.ExecuteNonQuery()...it says: Syntax Error near ','. I can't find the problem.
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?
Right now I am doing the following.

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.

how to connect to databse from vb and insert records ?
View 4 RepliesI'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.

View 2 RepliesI 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.

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?
