I have the following code to select records from an access table based on a date range. The user is required to select a week ending date (Saturday) from a datetimepicker field.The date field in access is formatted as short.The values in the database range from 12/04/2009 to 2/05/2009. When I select datetimepicker as 2/05/2009 (i.e. 2 May 2008), no rows are returned. Following is the resultant sql statement:
show: Select * FROM Work_Time WHERE WorkerID =1001 AND (WeekDate >=#26/04/2009# AND WeekDate <=#2/05/2009#)
However, if I select datetimepicker as 25/04/2009, the correct numbers of rows are returned. Following is the resultant sql statement:
show: Select * FROM Work_Time WHERE WorkerID =1001 AND (WeekDate >=#19/04/2009# AND WeekDate <=#25/04/2009#)

I have three tables,
Products(ProductID, ProductName)
Orders(OrderID, OrderDate)
OrderDetails(ProductID, OrderID) Junction table between Products and Orders.
For example, there are Three ProductID in Products table A01, A02, A03
Four OrderID in Orders table
1. 01/01/2009, 2. 03/01/2009, 3. 05/01/2009, 4. 07/01/2009.
OrderDetails data as below:
A01 -- 01/01/2009
A02 -- 01/01/2009
A01 -- 03/01/2009
[Code]....
then I want to display the date that A03 is not ordered from range 02/01/2009 till 08/01/2009 which could have the result like this.
DateMissingOrder for Product A03 in range of date 02/01/2009 to 08/01/2009:
03/01/2009
07/01/2009

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'm trying to integrate a custom control that I built into my vb.net project. My control contains 4 text boxes Month, Day, Year, and Time. My database field is a datetime field in SQL Server 2005.I am able to bind the data, but my control doesn't work when a date isn't entered. I'm pretty sure that this is a DBNull issue. I need to be able to insert NULL into the database when a date isn't entered. When a date is entered, I want to insert that date into the database. With the below code, I can't tab out of my control when a date isn't entered.

I have an MSAccess 2007 DB to record our employees Personal Days Off (PDO). Until now I have only had a form to record each single day taken. This results in time consuming repetitive entry when an employee takes multiple consecutive days or weeks off.
My database consists of two tables:tbl_PDO (to hold the Worker, DateTakenOff and TimeTaken) tbl_Employees (containing the Employees contact info, Name, Address, etc.) A form for Single date data entry with tbl_PDO as the record source and the following fields: (This is the original entry method one day at a time and works as it should)cboWorker(with Record Source tbl_Employee[Worker] DateTakenOff(ShortDate) TimeTaken (in hours) A form for Date Range entry with tbl_PDO as the recored source and the following fields: cboWorker(with Record Source tbl_Employee[Worker] StartDate EndDate TimeTaken (in hours) I have been trying to work with bits and pieces of code Ive found online to create multiple rows in a table based on a date range.[code]...

I am developing one desktop application using vb.net 2008 and Microsoft SQL Server 2005. fetching the data from database between a given range.
the date field in my table is of type VARCHAR(25) and the date format stored is dd-mm-yyyy. when I using the between clause in the SQL query then it is not giving all the data every time i.e. the date criteria in where clause is not working fine.
while my clients requirement is to keep the date format as dd-mm-yyyy and fetch the data according to the given range.
I search on the forum and found many queries to fetch the data by converting or type casting the date field within sql query but nothing worked.
The table structure that I am using is as follows
USE [Firm_master]

/****** Object: Table [dbo].[tblTransaction] Script Date: 05/17/2011 21:49:11 ******/

I'm trying to bind a combo box to a Access database field. I'm trying to do this with code instead of using the data sources wizard as I was told that this would be more flexible and better if distributing the finished program to other computers.
The result is that the form runs, but nothing is in the combo box.
I have also not used a dataset in my code, only a data table. Am I correct in thinking that this is plausible?

I am struggling to understand fully, I need to bind data from an access database to a datagridview. (the DB simply holds a list of product with their stock code, description etc) I need to bind this datagridview to a products collection without using a dataset to bind to the datagridview. I really don't understand this fully.
View 5 RepliesI have a program (below) which runs an SQL query on an Access database to bring back records based on the date a user selects. This issue seems to be that US date formats are the only date formats that SQL queries accept. I may be wrong, but this is my understanding. All my dates in the database are in EU date format (dd/mm/yyyy). What happens when i run my code is that I can not access a record with the date of 08/05/2010 unless the input date is 05/08/2010.

How to use a DateTimePicker to query a database table. Basically, when a day is chosen on the DateTimePicker, I want all the database entries for that day to be populated on Datagridview. My Datetimepicker name is datetimepicker1. The datagridview name is dgv. The database table is called QCAuditing and the row in the database, that has timedate, which I want to use for query is called date. I was wondering if someone can point me to the right direction here.
View 1 RepliesI have a select statement which was returning the required values but when I changed the OS date from English(US) to English(UK), it now returns null.

It almost looks like the dates in the combox and in the database are not the same and yet the date in the combobox is actually retrieved from the database and has been returning values fine until I changed the system date format.Here's my select command:
