I'm getting an error on my index simply setting a string field prior to using it and entering the loop. When I set this field within the loop I get a error still. how to go about Inserting records based upon a query in vb .net? The following is the code that I have:
Public Sub Insert_RunsizeUPCs()

I am using vb.net and sqlite as database. I am using below scenario to insert multiple records in database using a single query.

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 used following code searching records from a table in MsAccess and displaying in a Listview and it is working fine with the search criteria based on Discription.
CODE:
I also tried the above code to search records on the base of CustId and it worked fine too.My table DailyTransaction in MsAccess is as under:DTDate, DTTime, CustId, Description, Quantity, Price, Amount, AccountNumber, Name
Now I want to Search records on the base of Date I tried the following but it did not work.
Dim cmdText As String = "SELECT * FROM DailyTransaction WHERE DTDate=' " & TextBox1.Text & " ' "
Also i want to make following sort of query to retrieve data between two dates and to display the sum of amount group by DTDate. I could sketch following query and deifinitely it is so wrong with Syntex.Select * From DailyTransaction where DTDate Between textbox1.text AND textbox2.text Group By DTDate AND SUM(Amount)

View 7 RepliesI am working in VB.NET08 and Access Database. Generally we send or update a Value into a Column in a Table through any control like TextBox or Combobox...etc.
Ex:
rscitycountry.Fields(1).Value = Me.cmbpersonalcity.Text
rscitycountry.Fields(2).Value = Me.cmbpersonalstate.Text
rscitycountry.Fields(3).Value = Me.cmbpersonalcountry.Text
But I need to send a Value or Insert a Value in a Column through Condition. So I wrote a SQL Query for that. By Using this SQL Query I want to insert a value in a particular Column. How can I Update This Column Value in a Table? My SQL Query is :
"INSERT INTO tblPersonsInstitute(InstituteID) SELECT tblInstitution.InstitutionID from tblInstitution where tblInstitution.InstitutionName=" & Me.cmbInstitute.Text & " "
By using the above Query How can I Use? Where I can update??

In my program I have a combo box that the user selects a date from and a list view that the user selects an employee ID from. How do I properly design my database query string to use both the date selected and the employee ID selected?

Here is what I am trying to do with my query:
Dim ExactQuery As String = _
"SELECT * " & _
"FROM[JobTypeExact_Query] WHERE (EMPID = ?) AND WHERE (YEARMONTH = YM)" 'Define Exact job type query

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 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 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.
Inserting records one at a time. See below

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.

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.

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.
