I am running the following query against a database of research reference works (books, articles, etc.):
SELECT [Names].[Last] AS Authors, [References].PubYear AS [Year], [References].ShortTitle AS Title, [References].SourceWork,
RefTypes.Description
FROM ((([References] INNER JOIN
Contributors ON [References].ID = Contributors.RefID) INNER JOIN
[code]....
This query returns one row for each Author (contributor type=1), of the specified reference. The rows will all be exactly the same except for the Author last names taken from the NAMES table. For example:
Author Year Title SourceWork Type
--------------- ------- --------------------------------- ----------- ----------
Rahner 1966 Revelation and Tradition Null Book
Ratzinger 1966 Revelation and Tradition Null Book
I'm looking for a way to consolidate the string data from the Author column into one string, so that this can return a single row with the Author field looking something like "Rahner, Ratzinger" -- like one could do if it were numeric data by using the GROUP BY clause with an aggregate function such as SUM or AVG.
I would like to bind a DataGridView to the results of a query generated as text at runtime.How can I send a query as text to Microsoft Access and bind the results to the DataGridView?When the user clicks the button (ok_btn), I want the contents of the textbox (query_txt.Text) sent to Microsoft Access, then I want the results of the query shown in my DataGridView (results_grid).
Simple one-row queries are fine for now: (SELECT "a";, SELECT "a", "b";, SELECT now();)
I have a query that will go away an and find data Dim HSNs As String = String.Join(",", ListOfHSNs.Cast(Of String)().ToArray()) Dim query As String = "SELECT VALUE O FROM v_BillData AS O WHERE O.HSNumber IN {'" & HSNs & "'}" Dim hs As New ObjectQuery(Of v_BillData)(query, CType(Session("ObjectCon"), ObjectContext)) What I now wish to do is to use the results of this query to databind to a EntityDataSource?

What I'm trying to do is to write a generic rss reader that I plug in any URL into without worry if the feed has all the common properties. For instance in my example below I'm looking for pubDate, however if no pubDate exists in the xml I'd like to return the current Date. I cannot seem to get the syntax right though.
Dim xmldoc As New XDocument xmldoc = XDocument.Load(url) Dim feeds = From feed In xmldoc.Descendants("item") Select New With { _
If this is in the wrong section, I have a program that queries a database and puts the info in a specific format in a txt file. Now my problem comes w/ how to format the date.
Should I format the date in the SQL query OR is there a way to take the result from the query and format sometime before it is writen to the txt file? I'm not exactly sure how to do either. Would I need a subquery to get the desired date format?
I am using an access DB and wanted to create a query that returns user's in the db. First I need to check the db to see if it is empty. Then I need to check to see it my query returned any values. How do I go about doing this?
I'm a bit confused on how to grab query results. With VBA i would open a record set and have the results of the query written to that recordset. IN VB.net how can I grab the query result and throw each column into specfic arrays?[code]Now how would I force it to query my DB? I have a connection established already.After the query how can i play with the columnes and place them into arrays?
I had this query sp_msforeachdb 'select "?" AS db, * from [?].sys.tables' when I execute it in sql server, it return multiple results. How I can read all the results in my vb?
I am familiar with the VB6 ADO way of dealing with SQL queries and looping through the record set results.
However, what is the correct way to query a server, cycle through the results, and dispose of my query in VB.Net? All the ways I have been using seem to be unstable and crash randomly.
I have been using the following code:
Public Function GetSQLTable(ByVal strSQL As String) As DataTable Dim table As New DataTable Dim adapt As SqlDataAdapter
I am learning VB.NET and wanted to try and connect to a Oracle.DataAccess with this simple SQL Query but am stuck how to get my results.
Imports Oracle.DataAccess.Client Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click[code].....
I'm trying to execute a SQL query and pull the results into a text file. However, I'm getting an error in the bolded part. I think probably the biggest help would be an explaination of what the code in bold is actually doing. I pulled this from a book but don't think I completely understand. To me it seems like its saying that for each row in table 'extract'. Extract it, and write it?? But it doesn't seem to work that way. When it gets to that part, the error I get says that the row doesn't exist in the table
Private Sub btnExecute_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExecute.Click Cursor.Current = Cursors.WaitCursor 'hourglass cursor Dim connection As New SqlConnection
Why would a VB/ASPX page not return results for a query which runs fine with other Oracle clients? (Same username) The following code should first output the query and then execute it outputting a single exclamation point per record. However, it outputs the query (as it should), but does not return any rows (nor error). If I copy the query to SQL Plus (or other editor) as the same user, the query returns results.
Why might my code not output any results?
Dim MyQuery As String = "...some query..." Dim Factory As DbProviderFactory = DbProviderFactories.GetFactory("System.Data.OracleClient") Dim myConn As DbConnection = Factory.CreateConnection Dim myCommand As DbCommand = Factory.CreateCommand Dim MyReader As DbDataReader
I have a basic question about using a database with Visual Basic.I'm using a OleDb connection. I have dragged and dropped editboxes from the DataDource view. This automatically places the table navigation- bar on the form. When I run it this works fine.However I want to be able to search within the table, with an SQL statement.How can I connect the results from the SQL query to the navigation bar,such that the editboxes automatically take the values of the record without having to assign every textbox manually?
I need a clarification about using datagridview and query statement. i created a sql express database. In the project has been created a dataset with inside a table. In my form i used a datagridview and in automatic have been created BindingSource, TableAdapter, TableAdapterManager and BindingNavigator.
Till here everything is ok because i can add, delete and save members of the table.
Now i wanted to use another datagridview for a research but i don't understand what to use for do that.
procedure to search in a table using a new query?
I know that have been already done this kind of questions but i don't understant if using bindingsource, sqltableadapter, tableadapter ecc..
So I have coded connection to database and query but when I push button nothing happens. So my question is how can I fix that Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
I'm trying to export data from a sql query into a xml document. I need to automate this process because I have over 40 of these type queries that I have to post shortly after midnight each day. I've been trying to figure out how to do this for a few days now.
I'm not sure how to do the following (in VB.NET), I'm hoping you will give me some insight or examples on how it can be done. My database is an SQL one.I have an assets table, which in it has the amount, growth percentage, income percentage. There are multiple assets per client.
I need to get the amount, growth and income into three separate boxes or variables and I'm not quite sure how to do this. The only other problem is that there would be two or three rows returned also, which need to have those three variables or textboxes again. So for x amount of rows, I need 3 variables which the amount, growth and income will go into.
The reason I need everything into variables is that I can't find an effective way of showing each assets growth over x amount of years and the income it will produce into a data grid view. I'm able to do it if I specify what the growth and income are on the form, but not through the query.
