How Does DotNet Handle Parametrized Dates Where Programmatic Date Has No Time But Sql Date Has Time
Jul 16, 2010Thought 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
SELECT * FROM table
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?

View 13 RepliesError : Conversion Failed When Converting Date And/or Time From Character String
Mar 27, 2011The 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

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.

View 20 RepliesC# - Convert A Date And Time To UTC Time Based On The Time Zone Of The User?
Sep 6, 2009I have an ASP.NET application with a SQL Server back end. I am storing all my dates in UTC format and doing the appropriate conversions to the local time zone of the browser viewing it. One of the pages asks for a start date and end date (no times).
I am taking the start date and setting the time to 00:00:00 hours (midnight) and I'm taking the End time and adding a time of 23:59:59, so that the date range covers the whole day. Now what I'm trying to do is do a SQL query to do a search for records in this date range. The problem is, the data in SQL is in UTC time and the user is typing their dates and times in their local date and times. My quickest solution was to convert the date and time to UTC, then search the records. However, by doing this, I am to believe ASP.NET converts the given time and date to UTC based on the server time zone. How can I convert a date and time to UTC time based on the time zone of the user?
Convert Excel Date To Sql Server Date Time Format Using ACE Provider?
Jun 24, 2011I 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
DB/Reporting :: Search A Table, Confining To A Specific Date Range Based On A Date-time Column?

Date Time Picker - When Select A Date, The Text Does Not Go Away
Apr 7, 2011The 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.
