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?
Compare Dates And Select Matching Records Betweem A Selected Date Range
Jun 5, 2011am using sql 2005 and vb 2008.i need to compare dates and select matching records betweem a selected date range.say records between 11/13/2010 and 11/20/2010.e.thing is working ok except when it comes to selecting dates between 11/1/2010 and 11/9/2010.this is happening because when am retrieving the dates from database,its being retrieved in the format 11/01/2010 instead of 11/1/2010 and so it reports no records found,and knowing the limits of sql 2005 this is the only way i can retrieve the date.

View 2 RepliesVS 2008 - Append Now Time Part To Date Variable
Jan 11, 2010I'm working on a small accounting app. I have a query to show transactions with a running balance.
SELECT transactionid, transactiondatetime,
amount,
(SELECT SUM(amount)
FROM dbo.transactions as D1
WHERE D1.transactiondatetime <= D0.transactiondatetime) AS balance
FROM dbo.transactions AS D0
I capture a gamesheet for a certain week. so if I select a date on a monthcalendar the sheet applies to the weeknumber of the selected date. When I save transactions I take the date at the last day of that week as the transactiondate. I need to store a datetime though because my query works of the datetime to get an accurate running balance. How can I append now() time part to my date variable and then store that in a datetime variable to get a transactiondatetime.
Here is my code for getting a transactiondate:
Dim dt As New Date
dt = Me.MonthCalendar1.SelectionStart
'get last date of week. Friday
Dim tdate As Date = dt.AddDays(5 - CInt(dt.DayOfWeek))

Sql - Finding Start And End Dates From Date Numbers Table (Date Durations)?
Jun 19, 2009I have two tables: a schedule table that contains information about how an employee is scheduled and a numbers table in which each number corresponds to a date.
[Code]...
I can do this on the SQL side or the code side. I have Linq at my disposal if I need it. The table doesn't need to be compiled by SQL. This will happen dynamically on a website and should be as efficient as possible.I don't want to have to iterate through each and look for breaks in contiguous days if I don't have to.
