Basically i have a query string that when i hardcode in the catalogue value its fine. when I try adding it via a variable it just doesn't pick it up.This works:
Dim WaspConnection As New SqlConnection("Data Source=JURA;Initial Catalog=WaspTrackAsset_NROI;User id=" & ConfigurationManager.AppSettings("WASPDBUserName") & ";Password='" & ConfigurationManager.AppSettings("WASPDBPassword").ToString & "';")
This doesn't:
Public Sub GetWASPAcr()
connection.Open()
Dim dt As New DataTable()
Dim username As String = HttpContext.Current.User.Identity.Name
[code]....
When I debug the catalog is empty in the query string but the WASP variable holds the value "WaspTrackAsset_NROI"

I'm checking if the application needs to update before the user starts the software. But, they have to enter a few items of data and then press enter. When they do, if an update is available, the application closes, my update app runs and then the new version is opened. I want to just update when the application is loading, so they don't have to waste time entering data if the application is just going to close anyway. But when I run the block of code to check for updates, I get an SqlException.

[code]Myself and a coworker have stared at this quite a lot and we can't figure out why it's not working. The problem is in the value for @ID (since it still works when I leave the other one parameterized). The funny thing is, Just a few lines of code above it I have a different query that sets a parameterized value for the same ID, using the the same choices list that the For Each loop is getting the match variable from.Choices is a list of longs, and when I use choices(0) to parameterize ID in a query, it works. But now down here in this loop I have the new match long, and it doesn't want to make it work for me.

I have two tables say "Table1" and "Table2". I made a UNION query and saved it as "AllTimesFailure". It is worth mentioning, I am using Access DB. When I am trying to fetch the records from AllTimesFailure through oledbDataReader, it says "The Microsoft Jet database engine cannot find the input table or query 'AllTimesFailure'. Make sure it exists and that its name is spelled correctly.". I double checked query name and found correct but the problem still exists. when I run the same query as I pass through my command object, it works fine in Access query analyzer and fetches records normally.

I've spent a whole day on this already without figuring it out. I'm hoping somebody can help me translate the following MySQL query to work for SQL Server 2005:
SELECT MAX ( messages.date ) AS maxdate,
topics.id AS topicid, topics.*, users.*
FROM messages, topics, users WHERE messages.topic_id
= topics.id AND topics.user_id = users.id AND
topics.forum_id = " . $forumid . " GROUP BY
messages.topic_id ORDER BY maxdate DESC
$forumid is a QueryString value defined in the following VB.NET code-behind code:
forumName.Text = "<a href='ViewForum.aspx?forumid=" & row.id & "'>" & row.name & "</a>"

Banging my head against a wall here. I have a query that looks like this.
SELECT FirstName, LastName, Address
FROM Members
WHERE FirstName LIKE 'JOE%'
That works absolutely fine in query wizard and the DataTablePreview data window. However, when I do this.
SELECT FirstName, LastName, Address
FROM Members
WHERE FirstName LIKE ?
I get nothing when I run the fillby method. If I change the LIKE to =.
SELECT FirstName, LastName, Address
FROM Members
WHERE FirstName = ?
Everything works great. I need to get LIKE working though so I can wildcard search.
I'm using the SQL server OLE db connections if that means anything.
UPDATE
Using the LIKE operator doesn't work at all. When I just swap out = for LIKE. Nothing is returned.

I have an application that requires data be entered, and after entering, a button is clicked to process that data. Clicking the button works just as it should--the data is processed properly. In constructing a test module, I provide a set of data values, followed by:
btnWhatever.PerformClick()
Nothing happens. I have used this syntax for years, and it has always worked flawlessly. I have triple checked everything else and isolated the problem to the failure of the PerformClick(). The PerformClick() is in a test subroutine that does nothing but fill textboxes and labels with default data, then calls the PerformClick() on the button to begin processing. Again, the button works fine, the data is entered as it should be, but the PerformClick() does not fire the click event.

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.

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'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.

I have created a parameterized query in my tableadapter. Here is the SQL:
SELECT CalcinerID, Comments, CorrectiveActions, CrucibleOxideWt, CrucibleWeight, DCPressure, DCTemperature,
Date, DischargePressure, FeedPressure, FiredCrucibleOxideWt, GmSampleWt, LIMSNumber, LotNumber, MaterialType,
OperatorID, QualLabOperator, QualLabTimeStamp, RecordID, ToteBinNumber [code]....
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?
