Asp.net - Getting The Error "Query Input Must Contain At Least One Table Or Query."
Aug 28, 2011
I am using visual studio 2010 to create a form where you can edit,delete, or insert data from an accessdatabase. When I try to run the form in a web browser I get the error "Query input must contain at least one table or query." I believe that the problem lies with my code/syntax but I am unable to determine the cause of the problem.
<asp:AccessDataSource ID="AccessDataSource1" runat="server"
DataFile="~/App_Data/database.accdb" SelectCommand="SELECT * FROM [database]"
DeleteCommand="DELETE FROM [database] WHERE ([EmployeeID] = @EmployeeID)"
The database: "ID (Primary key)" | "Title" 0 | "title1"
[code].....
OK, before adding values to database, we should check if a row exists with this values :)TO do this, creating a Stored Procedure is a best way to deal with the database fastly.So... The problem now is, at the runtime, Miss OleDB throw this error:Microsoft Jet database engine cannot find the input table or query 'IF
i should say hi experts :D . Help me with this pretty code :)

ive been learning Vb.net at uni. Ive never used it before and im finding it a little difficult ( supposed to be easy )i usually code in c++ and MFC Problem I have craeted the database and added all the fields to the form.
When Creating a query using the sear Criteria Builder . I keep getting the error : "The schema returned by the new query differs from the base query" what does that mean and how do i avoid this problem in future
I have 7 company Divisions that sit in an access database.I then use this list to populate two comboboxes in my windows form.However I get a syntax error in my SQL Query if the Division name is more than one word.For example in my access database I have two columns one is a status column and the other is a division column. If for example the Division is called 'Corporate' the status column is called 'Status Corporate' and the division column is called 'Corporate'.The SQL query works fine in this scenario.However if I have a Division that is more than one word, lets say 'Operations Division' I get an error in my SQL Query that says -
Quote: Syntax error (missing operator) in query expression 'Operations Division'.Here is my code
sqlNewTenderDetails = "SELECT " & Me.DivisionBox.SelectedValue & " From BidRefCodes Where " & "[Status " & Me.DivisionBox.SelectedValue & "='Active'" daNewTenderDetails = New OleDb.OleDbDataAdapter(sqlNewTenderDetails, NewTenderDetailsTableCon)[code]....
I'm using Queries within the TableAdapter to grab certain data record field validations, most of them are using the Scalar Query to see if a certain condition returns a record or not.
I have one check I need to do that SUMs three fields and have tried it with both a Scalar and Regular Select, both return the results fine, my problem is creating the right syntax in the VB code to check the returned values.
Here's the Query Code in the Adapter (called GetInvoiceSum) and I pass it the cJobNum
SELECT sum(taxable) as taxable, sum(material+labor) AS subtotal, sum(tax) AS tax from ticket where jobnum = @cJobnum Here is the Code in the VB app - it gives me errors on the declaration and I've tried various types DataRow, DataSet, etc....not sure what I'm missing here and am very new at this....
Dim nSumTicket As DataSet = Me.TicketTableAdapter.GetInvoiceSum(cJobnum)
I have the following query that executes when my form loads. It's the rowsource for my combo box. The query is fine and populates the combo perfect, however, when i click into the combo box I cannot click out of it or even close the form. I have tried taking out the line of code that fills the form via table adapter on load and it works fine (opening the form unbound by the main table). Has anyone run into this before? I have another combo box on the form setup the exact same way and this is not happening. I've experimented with different datatypes etc....
code to populate combo box:
Public Shared Function LoadCallSource() As String Dim sConnectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:Documents and Settingsdiw07My DocumentsDaily Backupsphone memo backend.mdb"
I've recently been trying to figure out a way to get parameterized queries to work and i think i'm almost there but seem to be getting an error when executing my query
I have a table adaptor that pulls from the sql database, when I edit the table adaptor query it makes this specific table adaptor not a part of the dataset. I have added a column to my database which will contain an integer, when I try to add this column to the query this error occurs, i am using the configure area of the table adaptor. Error 'AuditProductsTableAdapter' is not a member of 'MemKingClient.MemKingDataSetTableAdapters.TableAdapterManager'.
I have a query that I have to run that requires me to get rows from a table based on the value of a field in another table (which I have gotten earlier). I currently have it done like this (simplified).
I have a query string that takes the value from a text box and passes it via a query string to a different web page. I need to add a hidden imput (state=MN) but can't get it to work. Everything I have tried hasn't worked.[code]
I am able to add an existing MDF database to my project and apply it to a form with the appropriate binders and navigators and such and it works fine. I can hard code queries that are very successful. My question is this: Is there a way to add a textbox to the form, where I could enter a valid query that would execute on a button click event? It seems like I should be able to do so with SqlCommand, but I am just stumped.
My problem is with the tickets table, I have listed the user that created the ticket, the tech who will solve the ticket and a user that over sees the ticket. All three users reference the users table. So how do I can I query the tickets table and get all three users that reference the same table storing the users?
Table1: Tickets 1) Ticketnumber 2) EnteredBy User 100 3) Issue
[code]....
What I can do now is something like this:
Select Ticketnumber, EnteredBy, Issue, UserName FROM Tickets INNER JOIN Users ON Tickets.EnteredBy = Users.UserID
I am trying to automate an access table make query through vb.net.It works fine the first time, but the second time it fails because the table already exists.Of course i can delete the table through code by it's name, but i want to let my .net-application find out wich table must be deleted. Or maybe there is a solution that doesn't fail with the error "table exists" without first deleting it.[code]
I am connecting to an Access database and using a parameter query with the LIKE operator to return all rows that match query. The string to search for is taken from a Textbox
sql =
"Select * FROM Allview WHERE Info Like" & "*" & CStr(TextBox1.Text) & "*" The query does not return any data in vb, but when run from access with same string, there is data returned.The connection to the database is done correctly, as I am able to return data with various other queries.

I am trying to run a query an Access db from VB. The general query which I want to run is
SELECT * FROM Patient WHERE Patient.PatientID = ? or SELECT * FROM Patient WHERE Patient.PatientLname = ?
I tried using an input box which captured the user input and pass that variable to the query, but that failed. Then I read about writing a function and using that, however, I keep getting an error which says Function not defined, but when stepping through the code, it seems to work. Here is my function: [Code]
I have to join two main tables, and I need to filter the results by elements in an ASP.NET web form. These filters are created on the fly so I have to use a lot of where extensions to filter the query. I want to execute the query with as optimized SQL as possible.
I am first doing a simple join between TW_Sites and TW_Investigators. Then there are two sub-tables that are involved. TW_InvestigatorToArea and TW_InvestigatorToDisease. While most of the where clauses are working fine, I have found a performance issue that won't be an issue right now, but will be an issue as the table gets bigger.
The arrays DiseaseCategories and DiseaseAreas would be the results of a CheckBoxList result.
Protected Sub LoadResults() 'Get Dictionary of Filters Dim FilterDictionary As OrderedDictionary = Session.Item("InvestigatorFilterDictionary") ' Initialize LinqToSql
I created a RDCL in the designer. I would like the User to Determine what is shown in the Report. How can I change the query at runtime? (ex. changing the customer Name)
This is the query that I have in the properties:
SELECT [Date], Address, Customer, Orders FROM Report_qry WHERE (Customer= 'JohnDoe')
how to take a query that returns a single row of data and load that data into textbox controls.I know about ExecuteScalar but it is only good for a single column of data from the query.
I've got confused at the moment.I've got one database to developed for MLM (Multi level marketing) company.so, there's one Members database.. each member have unique ID called membercode.. and all members can members under them.. can make 2 members down to 1 member.. all members are added in same table named "tbMembers" and for each member there's a "parentID" where I add member's membercode under whome that member is?.. right?
Now what's the matter is .. I want a SQL Query which can go under and under.. like 'John Doe' having two members under him named 'Suzan' and 'Ellie' and 'Suzan' is also having 2 members under her.. and same for Ellie. and for example.. 'John Doe' having about 300 members in his down line? All members are making transactions.. like they purchase product and Invoices are being generated (invoices tables have 'memberID'). Now the query is how to generate query which can calculate John Doe's Downline's TurnOver from invoices table's 'totalAmount' field's SUM?
I'm using Asp.net 2.0 (VB.net) and use SQL Server 2005 Express.
When I use the Execute Query button in the Tableadapter Query Builder, the query works fine; I get all the rows I expect. However, when I run this in my code, the query behaves like an equality statement (i.e. Lotnumber = @Lotnumber) rather than a LIKE statement (Lotnumber LIKE '%' + @Lotnumber + '%').Here is the code that is not behaving correctly. Note that I have a textbox, LotSearchTextbox, where I enter the portion of the Lotnumber that I want to use as the filter. I also have a button, LotSearchButton:
Private Sub LotSearchButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LotSearchButton.Click Try Dim SomeNumber As Integer = Me.LotCalcinerO2TableAdapter.FillByLotNumber(Me.CalcinerDBDataSet.LotCalcinerO2,[code].....
why the query works in the Query Builder but not in the code?
I have Access as my back end. Student is the database name and its path is c:Projectstudent.mdb And am having few tables in it. When i click a command button in vb.net a new table must be created in the path mentioned. And it should have the fields I declare. What s the query I need to use ? Is it possible to do like that ?
Dim tbl as String = Request.QueryString("tb") 'tb value = User Dim sql As String = "Select * From @table Where @Col = @ColVal" Dim para As New SqlParameter
[Code]....
what should I do to run the sql with given table name as parameter and avoid the sql injection.
