[2008] Date Parameter In MS Access WHERE Clause Uses DteStartDate AND DteStartDate Which Are Date Variables ?
May 11, 2010
In the TableAdapter configuration wizard I am using this query:
Code:
SELECT AttendanceID, StudentID, ClassId, DateOfClass, Absent
FROM Attendance
WHERE (DateOfClass BETWEEN #5/1/2010# AND #5/30/2010#)
Can tell me the correct syntax to change the #5/1/2010# AND #5/30/2010# so the WHERE clause uses dteStartDate AND dteStartDate which are date variables ?
I tried this but it tells me I need to use the to_date function. dteStartDate is already a date variable so I know my syntax is wrong.
Code:
SELECT AttendanceID, StudentID, ClassId, DateOfClass, Absent
FROM Attendance
WHERE (DateOfClass BETWEEN #" & dteStartDate & "# AND #" & dteEndDate & "#)

I'm building a dynamic query in my ASP.NET MVC project by the following: [code]Where basically the strWhere is a string that I build up a dynamic filter depending on what the user selects to search on.This works great until I need to add a date comparison to the date clause.[code]Which will end up as:"SELECT VALUE userInfos FROM MyDBEntities.UserInformations AS userInfos Where userInfos.BirthDate <= 10/09/1992"..But when i try to execute the query with the ToList whenever a date is in the where string i get the following error:The argument types 'Edm.DateTime' and 'Edm.Int32' are incompatible for this operation. Near WHERE predicate, line 1, column 103.

The purpose of my system is to calculate the number of motors (stored in a microsoft access table) that is being sent for repair according to the months. This information will then have to be displayed in a form developed in vb2008.
Below are the coding used:
Public Class FormReportMonthlyOverhaul
Dim connstr As String = "Provider= ..Database.mdb"
Dim rowIndex As Integer = 0
[Code]....
The Start_Date column in the MotorTable db is of 'Text' format. I have a feeling that the there's something wrong with the sql. That is why it returns 0 value.

i have to update the values in my database some of them are integer, some string and some date (as you can infer from the formatting)
i am using the following query:
UPDATE PatientProfile SET HospitalRegNo=" + hregno + ", PatientName='" + pname + "', PatientAge=" + page + ", PatientSex='" + psex + "', Address='" + add + "', ContactNo='" + cno + "', AdmitDate=#" + adat + "#, OperDate=#" + odat + "#, DischargeDate=#" + ddat + "# WHERE PatientNo=" + pno + ""
but its not working... i think there's a problem in formatting the date type variables

I have a textbox pulling an 'entryDate' field from my table using databinding. The field in the database is set to a 'Short Date', however when I bind that field to a text box and run the app it appends "12:00 AM" to the short date from the Db.
How do I get my databound textbox to simply display the short date which exists in the table?

I want to pass a comma delemited list of values as a parameter to a query I'm building using the designer in Visual Studio 2008 based on some strongly typed DAL tutorials I was going through. The query is going against a DB2 database. Here's what I want to do:
select * from prices where customer in(?)
It works fine win I pass in 123456 as ?But fails when I pass in '123456' (it is a char field so I don't know why this doesn't work; it must be adding these behind the scenes) or 123456, 123457 or '123456', '123457' I'm adding this page to a portal where all the data access is being done based on the DAL designer model with a BLL that calls it so I wanted to do it this way for consistency.

how I can ensure that conversion of a date to a string and a string to a date will give me the same date format.
For example:
Code:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim d As Date = Date.Now
[code].....
I'm actually only interested in the date part as the label text shows so f is more than I want.But also, the day and month are reversed.

Jst recently i came across the select() method of data table and felli n love with it instantaneously.
Basically I want query the data table on a date field, unfortunately the format of the date string returned from y database in to data-table and the date string i'm passing as inputs are different.
How can i make sure that the data is compared irrespective of the formats ? Can I use something like SqlParameters whoes data type is date for comparison ??
this is what i'm tying :
dim dat as date = "#1/3/2009#"
dt.select("StzDate ='" & dat "'")
entry in datateable dt : StzDate : 3/1/2009 12:00:000
Am I do'in something wrong ??
Also, can anyone redirect me to some site where I can learn a bit more about passing parameters to the select statement,etc...

"2010-08-02", I'm trying to convert it to UTC with the following code snippet..DateTime.ParseExact("2010-08-02Z", "yyyy-MM-ddZ", CultureInfo.InvariantCulture)When I print to the console, I get the following: 8/1/2010 5:00:00 PM.Is there a reason why the date shows up as the date before the date I'm trying to parse? I could just add a day to this to advance to the original day.

I'm fairly new to ASP.NET & VB.I've been asked to take an existing textbox that is automatically filled with the current date and allow the user to either add a "+" or "-" and a number or a spcific number and convert that into a date.I underdstand the basic concept on how to do this, but I'm running into some problems using the proper commands in order for this to work.The Textbox is called txtDate.What I've tried to do is this:
If txtDate = '+' Or '-' Then
DateAdd("d", txtDate, today)
End If

I am attempting to import data in a batch from an Excel Worksheet to a Sql Server database. Everything works except for the one date field in the spreadsheet. The date returned is off by four years from the value in the spreadsheet. Example: The Excel sheet has a date 10/24/2010 14:18, but when I look at the column in my query, the date is 10/23/2006 2:18. This pattern, 4 years and 1 day earlier, is repeated for every row in the worksheet.
The Excel column comes to me as a custom type, formatted m/d/yyyy h:mm. I receive this from an outside vendor and having them change the column is not going to be my simplest solution.
For what it's worth, the relevent part of the query is:
Select [Date Created] From MyWorksheet
