I am working on an application in Visual Basic Express using an Access 2000 database.I am trying to get athe following SQL query to work but get an error in Access.
The query is:
SELECT [ID], [Title], [Author], [Series], [YearPublished], [ISBN], [CoverPrice], [Style], [Condition], [Signed], [Comments], Count([Title]) AS CountOfBooks, Sum([CoverPrice]) AS TotalCoverPrice
FROM tblBooks
WHERE ID=[@ID];
The error is:"You have tried to execute a query that does not include the spec ified expression 'ID' as a part of the aggragate function."
The query works fine without the 'Count' and 'CoverPrice' count and sum to the query.
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?
I have a data table that looks like this:
USERNAME ICOUNT IAVERAGE DATE_LOGGED
LAGX01 1245 1245 05-07-2012
LAGX02 2211 1422 05-07-2012
LAGX03 1698 1112 05-07-2012
LAGX04 4598 1555 05-07-2012
LAGX05 2589 3245 05-07-2012
LAGX06 3321 1155 05-07-2012
LAGX07 3698 3458 05-07-2012
LAGX08 2589 4587 05-07-2012
LAGX09 1598 1142 05-07-2012
LAGX10 3156 1987 05-07-2012
LAGX11 5547 2011 05-07-2012
LAGX12 9456 3459 05-07-2012
Now, I want to execute a sql query that will display the top 5 based on average, so i did this:
SELECT DISTINCT USERNAME,IAVERAGE FROM myTable WHERE IAVERAGE > 0 AND DATE_LOGGED='05-07-2012' ORDER BY IAVERAGE LIMIT 0,5 and the result is:
USERNAME ICOUNT IAVERAGE DATE_LOGGED
LAGX03 1698 1112 05-07-2012
LAGX09 1598 1142 05-07-2012
LAGX06 3321 1155 05-07-2012
LAGX01 1245 1245 05-07-2012
LAGX02 2211 1422 05-07-2012
Now, I want to numberize my query result, so it will look like this:
RANK USERNAME ICOUNT IAVERAGE DATE_LOGGED
1 LAGX03 1698 1112 05-07-2012
2 LAGX09 1598 1142 05-07-2012
3 LAGX06 3321 1155 05-07-2012
4 LAGX01 1245 1245 05-07-2012
5 LAGX02 2211 1422 05-07-2012

View 4 RepliesHow to execute a query in visual studio 2008. What is the smooth process?
View 2 RepliesI don't like the verbose way of adding DataRows one by one via Tbl.Rows.Add, so i've created this pseudo LINQ query that does nothing but adding rows implicitely:
Private Function GetData() As DataTable
Dim years = {"2010/2009", "2009/2008", "2008/2007", "2007/2006", "2006/2005", "2005/2004", "2004/2003"}
Dim tbl = New DataTable
tbl.Columns.Add(New DataColumn("Year"))
[code]....
As you can see i don't need the result of the query at all, it's only purpose is to iterate and call DataTable.Rows.Add. So the result is already available in the DataTable itself and not needed from the query.Admittedly this question is somewhat hyphotetical because there would not be a big difference in using f.e. ToList and normally a query's purpose is to return something.But anyway, what's the cheapest way(in terms of memory consumption, execution time) to execute a LINQ query when only the execution and not the result matters?Edit: Ok, thisquestion was a quick-shot and a chicken-and-egg problem. I wanted to reduce 20 lines of code to a single line but noticed that i need some kind of DataSource for the LINQ-Query. Therefor i've created the Array. But at this point i could have simply used a for-each loop as well to add the DataRows.
Conclusion: Use a LINQ-Query for what it's for: a query. Then this question is pointless since there is no cheapest way but only that which returns the correct result.
I would like to run a query in background (using a BackgroundWorker) in this way[code]...
...but, because of deferred execution, the actual getting of the data does not happen in the "BackgroundWorker" thread, but in the "RunWorkerCompleted" Sub, making the BackgroundWorker itself useless.Is there a right way to do this without looping through the "MyQuery" to get the results and copying them to another object to pass it to the BindingSource?

I'm new to VB.NET. I'm trying very hard to not go screaming back to VB6...... I have a Query stored in an Access2000 database called 'build_VNMON'. (Does that make it a Stored Procedure ?) It uses multiple tables and multiple Union Statements to arrive at the desired results. It may not need to be as convoluted as it is, but I inherited it, and it works. What I really need is to output one column of the build_VNMON result to a text file, so I'm trying to use an OleDbDataReader.

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 -

View 1 RepliesI have this flood-fill algorithm, based on a queue (I tried the recursive method but pictures are too big and it was causing stack overflow).The problem is that when it makes the second pass in the for-each loop, the program crashes and compiler gives me the message "Collection was modified; enumeration operation may not execute.".Well, of course I know the collection was modified (it supposed to be!) since I am adding necessary items to it on-the-fly within the loop. What I cannot understand is why it happens since the for-each is based on the remaining items in the collection and not in a numeric index.
