Sep 28, 2011

When using INSERT INTO statement to SQL 2008 R2 to a column with data type  as date and the data I am taking from a DateTimePicker control with date format as short. When my system date format short set to dd/MMM/yyyy the INSERT INTO statement is working perfectly but when the system date format short set to dd/MM/yyyy I am getting the above error.I tried by changing the control format to custom and dd/MMM/yyyy but still the same error is coming.I am using VB2010 and SQLExpress 2008 R2 SP1?

Conversion Failed When Converting Date And/or Time From Character String?

Jan 1, 2011

cmd.CommandText = "INSERT INTO Dropping (form_num, filing_date, approval_date, status) VALUES ('" + fnum + "', '" + deyt + "', '" + nulll + "', '" + stat + "')"

here is an sql query statement i run in vb.net. i keep getting the error of "Conversion failed when converting date and/or time from character string." whenever i try to execute this. the datatype of filing_date and approvale_date is "text" but the deyt variable is originally Date, converted to string: (Date.Today).ToString, like so. nulll is simply a variable with vbNullChar as its value.

I used to query:

Dim a As String
a = "INSERT INTO tblVisitor(Name, Sex, TimeIn, EnterDate)
VALUES('"& txtName.Text &"', '"& cboSex.Text &"', '"& Now() &"', '"& DateTime.Parse(cboEnterDate.Text) &"')"


Which cboEnterDate is my DateTime Picker. Then I got the message:Conversion failed when converting date time from character string.

Error : Conversion Failed When Converting Date And/or Time From Character String

Mar 27, 2011

The error is: Conversion failed when converting date and/or time from character string.Basically I'm trying to make it so that when someone clicks a location in a list box it increments the correct field in a Stats table by 1 to say that they clicked the location. I've been trying to solve this for a while now and can't get anywhere. My date is in date format, and so is the Date field in my Stats table. My code can be seen below.

Dim Current As String
Dim Check As String
Dim objCmd2 As Object


The issue comes in with the second SQL statement I think. I don't understand why adding a date into a date field would be an issue, I've tried adding it as a string which didn't work.

Ensure That Conversion Of A Date To A String And A String To A Date Will Give The Same Date Format?

Jan 16, 2012

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:

Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim d As Date = Date.Now


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.

Converting Date And Time Format To Date?

May 3, 2010

I have a problem. I'm making a alarm clock and I need a way of converting a "dd/MM/yyyy HH:mm:ss" format into a date time format. This means I'll be able to compare the dates in a listbox using the for each function, to the current date and see whever it has passed and therfore the alarm should be deleted. It is currently in a string form so I can't use < and > to compare it to the current date as that is in a date form. I've tried using CDate but it doesn't work as it only will convert these formats:

"August 12, 2004", "2:07:30 PM" and "August 12, 2004 2:07:30 PM"

Converting A Date-string Into A Date Object?

May 1, 2010

I'm using date in the format dd-mm-yyyy and I need to convert a string inthis format to a date type.My string is "18-01-2010" but when I do the conversion using dim TargetDate as date=CDate(TgDstr).where TgDstr is "18-01-2010", the resutant TargetDate, as note in the debugger window, is #1/18/2010# rather than #18/1/2010#  which I expected.What change in code should I made to get the desired result?

(P.s. I've checked the current culture with the following line of code:

Dim str As String = CultureInfo.CurrentCulture.Name and get the result 'zh-HK'... and the date-time format I find in the control panel is also in dd-mm-yy format)

Conversion Failed When Converting DateTime From Character String

Feb 11, 2011

I have two datetimepickers on my form to set a start date and end date for a SQL server database query. I am passing these dates with parameters to my query from the .Value of the datetimepickers. When I run the program, the code returns an error of "Conversion failed when converting datetime from character string" I am not converting anything in my code. It is my understanding that the StartDatePicker.Value is already a datetime and does not require conversion.

Here is some code:
'Define Wages_Query
Dim Wages_Query As String = _
"SELECT [Department], [Operation_NUM], sum(STWag) as [STwag], SUM(OTWag) as [OTWag]," & _
" SUM(Shift_Diff) as [Shift_Diff]," & _
" SUM(COALESCE(STWag,0) + COALESCE(OTWag,0) + COALESCE(Shift_Diff,0)) as [TotalWages]" & _
" FROM dbo.Financial" & _
[Code] .....

How Does DotNet Handle Parametrized Dates Where Programmatic Date Has No Time But Sql Date Has Time

Jul 16, 2010

Thought I'd see if Stack overflow is quicker than me testing something while I get a thousand interruptions from other work :)

I'm updating an old VB net application and trying to refactor some of the logic as I go. The app looks for data from a single date across a few tables and writes that view to a file.

Writing the query in SQL I'd get the equivalent of

WHERE CAST(FLOOR(CAST(table.date AS float))AS datetime) = '15-Jul-2010'

Ideally I'd use

SELECT * FROM table WHERE date=@input

and add a date object as a parameter to a System.Data.SqlClient.SqlCommand instance

Are those two comparable? Will I get the results I expect?

Converting Julian Date To Regular Date

Apr 26, 2010

This should be really simple and I figured out how to do it in VBA but it's different in .NET. I have a 3 digit Julian date that I would like converted to a regular date (Gregorian). So if the number is 91, then that means April 1st (non-leap year) and if it's 304 then that means October 31st (also non-leap year). In VBA I was using the Day and Month functions to help me get an output to make it mm/dd format.

Convert Excel Date To Sql Server Date Time Format Using ACE Provider?

Jun 24, 2011

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

Would it be possible to search a table, confining to a specific date range based on a date-time column, and get a count of the 10 most used words in a particular var-char column excluding a list of words?All in SQL?Currently I am pulling out the records that match and sorting through the contents outside of SQL, I would think where I can do it directly on the server it would be more efficient.(SQL 2008)

Date Time Picker - When Select A Date, The Text Does Not Go Away

Apr 7, 2011

The problem that I'm having is that when I try to select a different date, the text doesn't go away. That may make no sence, but let me tell y'all what I've done.

1: Created a GroupBox
2: Put a DateTimePicker in the GroupBox
3: Put TextBoxs in the GroupBox
4: Changed the DateTimePicker to look like this:
A)Checked - False
B)Allow Drop - True

I thought that if I changed that, then the text in the text box would go to that specific date. It didn't do that, it just stays the same. What I'm trying to do is enter text in say 3/7/11 and when I choose date 6/12/12 it will display blank text boxes for me to enter something different.

Using The Date/time Picker For Arrival Date Only?

Nov 10, 2009

I am having a bit of trouble with using the date/time picker in a project.It is a program for calculating travelodge hotel accomodation prices. The price for a weeknight is 40 but weekends increase to �50.The code which I wrote is this:

For i As DayOfWeek = dtpArrival.Value.DayOfWeek To dtpDeparture.Value.DayOfWeek
If dtpArrival.Value.DayOfWeek = 1 Or 2 Or 3 Or 4 Then
PriceDecimal = PriceDecimal + 0[code].....

It does not work obviously because I am using the date/time picker for arrival date only. I think I need to use some other value which i would presume is something like "If DayOfWeek = 1 or 2 or 3...." but this will not work.

Find The Closest Valid Date To One Given As An Invalid Date String?

Aug 18, 2010

So there's this accounting package at my client that spits out text-based reports with invalid dates, like February 31st or September 31st.The reports are formatted with spaces and mono-spaced fonts. The data that gets parsed out are fed into a more formal local SSRS report, and that's about all you need to know.

What I am interested in fixing is the situation where a date is invalid and can't be converted into a DateTime struct. The date format from the report is "MMM-dd-yy" (e.g. "Feb-30-10"). The date strings need to be fixed before being shown in the formal report. I've seen this done two ways in my time as a developer, and I want to come up with a cleverer way of doing it (if there isn't a built-in way I don't know about).The first bad method (I can't believe I'm even showing you!):

Dim month As Integer = <Parse out the month from the bad date string>
Dim day As Integer = <Parse out the day from the bad date string>
Dim year As Integer = <Parse out the year from the bad date string>
Dim validDate As DateTime
