I have the following code which will only return one column of 41.
vb.net
Using Command As New OleDb.OleDbCommand("SELECT * FROM Products_TAU WHERE ItemID= @ItemID", Connection)
Command.Parameters.AddWithValue("@ItemID", ItemID)
[Code]....
That table alone is filled with 76 records and has 41 columns of data to pull.. this is only returning the first column of the row indicated by the where clause.
Before I had the where clause call it by lineID which there is 4 records of that... and it was able to pull 4 columns from it...
I am new bie in Scripting world.I wrote a script in vb 2008 to query active directory information.Even though the script task executes successfully when i tried toretrieve records from the object variable using for loop container in ssis it gives an error the object variable doesnt have valid data n it.i suspect that i am facing errors in assigning the result set to the package variable declared as object.Please could someonehelp by having a look whether the data will be assigned correctly according to my script.i am trrying to pass the information queried from ad to package variable gvresults described as object.
I'm trying to connect and query a .dbf dBase table. I'm fairly certain I've got the connection string formatted properly, because I am no longer receiving errors that I can't locate the table.I've tried everything I can think of, and nothing seems to work to make a valid query. I've tried all sorts of syntax changes around the table name (which is just 'buildings'...nothing fancy). The error is a syntax error with an incomplete query on the executereader line.
I'm looking for a control that allows images to be placed onto it and moved about. Moreover, I need to draw lines between the images. It will sort of be like the query designer in SQL Man Studio. It will be used as a virtual desktop where a variety of objects (and their icon representations) can be freely placed and moved. I'm having a blank and cant remember where I saw this before.
For some reason every time I execute the code, it gives me the error "No value given for one or more required parameters" and it points to the ExecuteNonQuery. Below is the relevant code I have.
Public Function sqlUpdate(ByVal varBalance As Double, ByVal varWithdrawlAmount As Double) As Double Dim dbCon As New OleDb.OleDbConnection dbCon.ConnectionString = "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source = dbATM.mdb" Dim query As String Dim cmdUpdate As New OleDb.OleDbCommand dbCon.Open() varBalance = varBalance -
in pervious version of VB (DAO 3.6) I used to be able to delete a query object and then creating it again (not the records) using the code below. but I am having a hard time finding how to do it using the OleDb in VB.net.
Dim ws As Workspace, db As Database Dim qy As QueryDef db.QueryDefs.Delete ("WISE QUERY")
I have a program (below) which runs an SQL query on an Access database to bring back records based on the date a user selects. This issue seems to be that US date formats are the only date formats that SQL queries accept. I may be wrong, but this is my understanding. All my dates in the database are in EU date format (dd/mm/yyyy). What happens when i run my code is that I can not access a record with the date of 08/05/2010 unless the input date is 05/08/2010.
I am connecting to a MS-Access 2007 database using VB 2010 and OLEDB. Conducting the following test seems to suggest that MS-Access does not interpret DBNull.Value correctly when sent as a parameter from OLEDB:[code]
You can query active directory with an OLEDB provider called ADSDSOOBJECT. This works great except it only returns the first 1000 rows. The following article shows how to work around this limitation in a vb script by setting the "page size" property of the command object. [URL]..I have been able to reproduce that code in VB.NET, but I am having problems getting it translated to OLEDB syntax, because there doesn't seem to be a "Page Size" property, or indeed a "properties" collection of any kind, in OLEDB.
I have database with table called "Konzultacije" with field "Vrijeme" (Date/Time). I have datagridview (DGKonzultacije) with columns. Column (1) data format is set to date/time. I want to delete record from "Konzultacije" table depending on selected cell in datagridview but only I can get is error.
This is my code:
Dim iSql As String = "DELETE FROM Konzultacije WHERE Vrijeme = " & DGKonzultacije.CurrentRow.Cells(1).Value conn.Open()
[CODE]...
If i add apostrophe like this:
Dim iSql As String = "DELETE FROM Konzultacije WHERE Vrijeme = '" & DGKonzultacije.CurrentRow.Cells(1).Value & "'"
error is raised: Data type mismatch in criteria expression.
Just wondering if i might hit a snag in my program. Ive got 10+ users using the same files, via a Oledb to put info into an excel spreadsheet. If 2 or more people save there file at the same time will the program go into read only on one person. Normally one 3 will use the file at one time. I know Sql itself would be better to use. best way i can describe it, normally using excel if you manage to open the same file twice one opens as normal but the other opens as a Read only file, will the same thing happen if im using Oledb connections?
I am trying to query WMI to get the current IP address of the computer.I have the following code, which queries the MAC address, and this works fine.But if I change the query to "ipaddress" (a valid property), I get a run-time error, something about a type mismatch [code]
i am creating a pda application using vb.net and sqlce and i can't seem to get parameterised query (or atleast i think mine is one) working.i dont know what i am missing because on the code below, i still get a END OF STATEMENT EXPECTED.[code]

statement = "SELECT OrderID, (SELECT VendName FROM Vendors WHERE Vendors.VendorID = Orders.VendorID) " & ",OrderDt, RcvdDt, OrderTotal " & "FROM Orders " & "WHERE VendName=? " & "ORDER BY OrderDt DESC" Dim cmd As New OleDbCommand(statement, connection) cmd.Parameters.AddWithValue("VendName", txtVendorFilter.Text) Dim reader As OleDbDataReader = cmd.ExecuteReader(CommandBehavior.Default)
I was trying to do this before by simply concatenating the textbox value right into the SQL and I was getting a "No values given for required parameters", and read that that I should use parameterized queries instead. So I tried this and it doesn't give me any errors, but the reader never has anything in it. I've never used parameterized queries before, so I'm a bit lost as to why this isn't working. I've changed the above code to account for OLEDB from what I briefly read on how it should work, and it's giving me the "no values given for required parameters" again.
I'm using vb.net express with access 2010.Everything is working fine except for a simple query:SQL: SELECT * FROM Customers WHERE Name Like 'Ale*'Which returns all the names starting with Ale. Now in my .NET code I wrote this:cmd = New OleDbCommand("SELECT * FROM Customers WHERE Name Like " & Chr(39) & Name.Text & Chr(39), connection)Now when I start the app and in my textbox "name" I write Ale* I have the following expression:SQL: SELECT * FROM Customers WHERE Name Like 'Ale*'But when it executes from .NET (dr = cmd.ExecuteReader) it doesn't find ANYTHING.
[code]its show me that it have written the command but when i stop the program and see my db its is not there. i've searched the net and alot of books but i cant seem to make it work.
With DataAdapter i passed a query and this is working....
Dim strSQL1 As String = "SELECT tbl_Items.GroupName, tbl_Items.ItemName, tbl_quantity.Quantity, tbl_quantity.QtyDate FROM (tbl_Items INNER JOIN tbl_quantity ON tbl_Items.ItemID = tbl_quantity.ItemID)WHERE(tbl_quantity.QtyDate = #12/29/2009#)" Dim da1 As New OleDbDataAdapter(strSQL1, DataConn) Dim dt1 As New DataTable da1.Fill(dt1)
But when i give the date as this, not working...
Dim tmpDate As DateTime tmpDate = System.DateTime.Now.Date Dim strSQL1 As String = "SELECT tbl_Items.GroupName, tbl_Items.ItemName, tbl_quantity.Quantity, tbl_quantity.QtyDate FROM (tbl_Items INNER JOIN tbl_quantity ON tbl_Items.ItemID = tbl_quantity.ItemID)WHERE(tbl_quantity.QtyDate = " & tmpDate & " )"
The below query fails with Null Reference Exception when there are elements in BOMIDs where MatID property is nothing.I thought the 'x.MatID isnot Nothing AndAlso' would prevent the x.MatID.Process part of the where from being executed. There are a couple elements in the BOMIDs collection that where MatID is nothing.
From x In BOMIDs _ Group Join y As PurchasedProcess In SpecialProcesses _ On x.MatID.PurchasedProcess Equals y.Name _ Into G = Group _
I am trying to prevent from having to escape apostrophes in my string variables by using a parameterized query with a OleDbConnection, but it is not working. I am trying to insert into an Access db and I keep getting those pesky html codes.
Dim pConn As New OleDb.OleDbConnection pConn = New OleDbConnection(cb.ConnectionString) Dim SqlString As String = "INSERT INTO Strings (Mlt_String_ID, Lng_ID, Strg_Name, Sht_Text, Lng_Text, Alt_Text) Values (@Mlt_String_ID,@Lng_ID,@Strg_Name,@Sht_Text,@Lng_Text,@Alt_Text)"
I have a SQL 2005 table called Customers and i would like to query the table for exact match and partial match. The exact match query is working OK but when i use the partial match, it doesnt return any result. Strange thing is, it works inside the query designer, it returns rows. On the dataset, if i right click and say 'Preview Data' and supply the search criteria, it doesnt bring in any rows. Same happens in the vb.net form also. Instead of partial string, if i supply the full customerid, it returns a row.Whereas I can return rows on another table, Suppliers. I dont know where the problem lies. Here is the sql:[code]In fact, I am trying to use the wizard generated code and details on the form. No changes done to the code or form.The customer id is nchar(10) column and is the primary key also. I ran the same steps on the Northwind database too, and the same problem exists.
