I have the following code:
Code:
Imports System.Data.SqlClient
Public Class Form1
Dim ReturnValue As Object = Nothing
[Code].....
which should return back the next available sunday to me from the database. What I'm getting back is 01/01/0001 - 01/08/0001.
I've tried a couple of versions of this but they all produce the same date.
I am working in VB.NET08 and Access Database. Generally we send or update a Value into a Column in a Table through any control like TextBox or Combobox...etc.
Ex:
rscitycountry.Fields(1).Value = Me.cmbpersonalcity.Text
rscitycountry.Fields(2).Value = Me.cmbpersonalstate.Text
rscitycountry.Fields(3).Value = Me.cmbpersonalcountry.Text
But I need to send a Value or Insert a Value in a Column through Condition. So I wrote a SQL Query for that. By Using this SQL Query I want to insert a value in a particular Column. How can I Update This Column Value in a Table? My SQL Query is :
"INSERT INTO tblPersonsInstitute(InstituteID) SELECT tblInstitution.InstitutionID from tblInstitution where tblInstitution.InstitutionName=" & Me.cmbInstitute.Text & " "
By using the above Query How can I Use? Where I can update??

View 2 RepliesBasically 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:

When I debug the catalog is empty in the query string but the WASP variable holds the value "WaspTrackAsset_NROI"

I have a form showing a datagrid that is filled with info from an Access database table. The table only has 3 fields: two of them are string type and the third one is boolean. The first String type field is also the primary key (this field is called "clave"). This datagrid is supposed to let the user select one of the rows and then click on a button to delete that row. I'm trying to do that with the following code:

View 2 RepliesI 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

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.

View 2 RepliesI'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?

I'm trying to do an Insert into a couple tables on one form with data controls. The problem is I don't know the approach. You see, the client has books to sell. He has catagories and he wants to add many catagories for each book. One or more catagories. It would seem to me that this is a many to many normalization. Being that one or more catagories can belong to one or more books? If this is incorrect, please tell me, as I thought it was a one to many earlier with one book having one or more catagories? Anyway, I need to be able to allow the client to enter one book, and then assign one or more catagories? He wants the potential buyers to be able to query books by catagories obviously. Wondering what approach to use? What data controls, and is it possible with just the controls, or do I need to write a stored procedure to grab the ID from the book using the @@Identity SQL statment?
