I am using OleDb, trying to do this:
Dim d as Date = DateSerial(Year(rptDate), Month(rptDate), 1 - 1)
Dim conn as OleDbConnection = new OleDbConnection(connStr)
Dim cm as OleDbCommand = new OleDbCommand()
[code]....
I know that d is the same date as the one in SQL server, specifically 3/31/2011 12:00:00 AM.
I have the properties. I have the format property set to TIME. The text box on the form now shows the time. But when you click on the pull down, you get the date picker.

I prefer to solve this problem at application rather than db level. NOTE: DueDate in database is of type datetime. I'm coding in C# interacting with Sql-Server. I hope my question is clear enough.
I have a month and a year dropdownlist which give me the following string 01/2012 The date format in my db is "2012-01-01 00:00:00" but when I select an individual date and put it in a message box it converts to "01/01/2012"
I've altered my select statement below to reflect the converted date. However Im still not given the correct details. Any ideas? Is there a particular format that I need to use when dealing with a timestamp field? Can I even use the "Right" function in a select statement?
Dim newRecordDate As String = val1 & "/" & ComboBox2.SelectedValue Dim sql2 As String = "Select CatA, CatB, CatC, Cost, Currency, MarketingCode, Comment, RecordDate from vw_tblP_Usage_Details where puid = '" & puid & "' right(RecordDate, 7) = '" & newRecordDate & "'"
I am trying the following to select a long date, but becase the value is stored in SQL database as DateTime I am unable to return any results unless minutes and seconds match perfectly...I then tried to use 2 calendars and have the same issue with the DateTime format..

I'm trying to create an auction site using asp.net. My auction's start date & time and end date & time are stored in my sql server 2008 r2 database as datetime types. I'm using vb.net. I'm trying to create a select statement in which I can query the date and time portion relative to the current date and time (so as to only display current ongoing auctions). I can successfully query the date portion using the Date.Now function, but the time is giving me a hassle. DateAndTime.Now doesn't work. I've even tried to separate the time and date in the database, but I still can't get an effective query. Here are two examples of code which I've tried:

I have a query that executes fine in TOAD, but when bringing back the results with either an ADO.Net DataReader or DataAdapter/DataSet, it's not recognizing a column in the select statement. See the query below... the column in question has its data coming from a dynamic table or sub-select or whatever you call it. I don't see why this is a problem in .Net:

I'm relatively new to VB. I want to perform a SELECT statement that uses a variable to return a value, example;
mysql> SELECT room_description FROM room_descriptions WHERE current_room = 'someVariable';
And display the result in a TextBox i.e. TextBox.text = someVariable.
So how do I perform a query from VB that passes a variable? How do I assign the result to a variable?

As you can see from the code below there is a lot of repeated code. I want to move that code outside the if statement as it's performed for each if, but the Dim employees variable I'm declaring is causing my issues. I don't know how to declare the variable outside the if statement as it's a linq-to-sql query, so I can later define it within the if statement. I can't access employees outside the if statement, so I can't just put the repeating code outside the if statement.

The data type for my DATE column in SQL is smalldatetime. I want to perform a query which selects records based on the the selected date of a calendar object.
A user clicks on the date and the date is stored in ddlfilter2 DDLfilter2.Items.Add(CalendarMain.SelectedDate)
mystring = "SELECT * FROM view_main where date" & "='" & DDLFilter2.Text & "'"
produces this "select * from view_main where date='24/03/2009'
I then get an error saying "The conversion of char data type to smalldatetime data type resulted in an out-of-range smalldatetime value."
In the SQL database the data is displayed as "24/03/2009 00:00:00" is this why the query is failing?
