Sql Server - Set A DateTime Database Field To "Now"
Dec 20, 2010
In VB.net code, I create requests with SQL parameters. It I set a DateTime parameter to the value DateTime.Now, what will my request look like ?
UPDATE table SET date = "2010/12/20 10:25:00";
or
UPDATE table SET date = GEtDATE();
In the first case I'm sure that every record will be set to the exact same time. In the second case it depends on how the DBMS processes the request. Which leads me to the second question : does SQL Server set the same date and time when updating a large table with NOW() ?
EDIT : replaced NOW() (which doesn't exist in SQl Server) by GETDATE().

I am not sure if this should be in the SQL or vb.net section.But, Basically I have a vb.net application from where I insert a datetime field into the SQL Server Database. Now for some reason the SQL server field(which is datetime) will not display AM/PM, I have referred this link where my code looks like this:
Dim dateToDisplay As DateTime = DateTime.Now dsNewRow.Item("date_created") = dateToDisplay.ToString("MM.dd.yyyy hh:mm:ss tt")
I tried stepping into the code by debugging and it seems to be inserting the PM but is not displayed in the table QuotedateToDisplay#8/12/2011 6:01:06 PM#Date

I'm trying to add the date and time of Today into a Sql-database-field that has the datetype datetime.
[Code]...
the msgbox gives me the following result: 29/01/2011 18:49:21 my sqlException gives me the following error: 102 - Incorrect syntax near '18'. Is it better that i set the datatype to char in my sql database? It's maybe a bit easier? When I do that, can I calculate with these date?

I am using the Convert command to do this, but I am getting the error 'Undefined function Convert in your expression'. Is there another function I should be using? Or am I missing and Import command at the top?Here is the code (field TimeofFall is the one I am having trouble with):

In my VB project I am returning an SQL datetime field to a date variable mdtCreated = CType(oReader("dtCreated"), Date) In an example it returns mdtCreated as #5/13/2011 2:59:43 PM# which is correct. Later on I want to show this as a string to dd/mm/yyyy format. I have tried mdtCreated.ToString("dd/mm/yyyy hh:mm:ss") But that returns "13/59/2011 02:59:43". I want it to return "13/05/2011 14:59:43" How can I achieve this?

I'm trying to format a datetime field to just show the date. The datetime is bound to an asp:label and for the Text attribute I have tried the following....
Text= String.Format("{0:D}", '<%# Bind("CReviewDate") %>')
and
Text= String.Format("{0:D}", <%# Bind("CReviewDate") %>)
[Code]....
In all cases I get a green wavy line under the equation and the tip help says "Validation (ASP.Net): If this attribute value is enclosed in quotation marks, the quotation marks must match. String.Format("{0:D}", DateTime.Now) is the syntax that I have been told should work.

There are lots of questions about this but I've not been able to solve my problem using the answers to any of them (after many, many attempts..)
I'm working in vb.net creating an asp.net web application. I have an SqlDataSource and a GridView on my page.
I want to change the DoNotMail boolean value represented by a Gridview checkbox and automatically update in the database if the checkbox is checked from 0 (False, Will Mail) to 1 (True, Won't Mail) here is the code I used. [code]...
is it possible to do a two way sync on the entire gridview when the user hits a button so you don't have to do an update every time a row is changed? because the user might check the box and then check another box then uncheck a box and it would be a lot of updates...

So I created a table and one of the columns is is called currencydate, and has a datetime data type. Within my vb scripts, i've taken a filename and extracted the date components from it. an example filename is WER22402.10. The part in bold is the date meaning 24th February 2010.
I use the following function to extract the date values and convert it to a date type.

I am creating a database in VB.NET for a movie rental place. I currently have three forms;
Member Information
DVD Information
Borrow DVDs
What I would like to do is when I am viewing a member's details, if I click a button 'Borrow DVD for Member', the member's ID number transfers over to the Borrow DVDs table in the Member ID which also would hold some information from the DVD Information table, but I'm sure if i can figure out how to do this firstly, I will be able to apply the same rule and work it out myself.I have been trying to use a query statement like;
INSERT INTO [Borrow DVDs].[Member ID] [IN goodstuffvideos.mdb]
SELECT [Member Information].[Member ID]
FROM [Member Information]
but that has been coming up with error codes and completely not working.
Borrow DVDs table fields are: Borrow ID, Member ID, DVD ID Number, Hiring Fee, Borrowing Limit?
DVD Information table fields are: DVD ID Number, Title, Rating, Hiring Fee, Borrowing Limit Member?
Information table fields are: Member ID, Family Name, Given Name, Address, Town/Suburb, Postcode?
The error coming up is; Error in INSERT statement. Unable to parse query text.And under that it says The query cannot be represented graphically in the Diagram and Criteria Pane.

How do I achieve the same in VB.NET which is so easily done in SQL Server.
Select Case(GetDate() as VarBinary(8)) --Gives the Current Time in Hex
How can I create the same string in VB.NET so that I can compare in SQL Server as such -
Select Case When GetDate()=Cast(0X00009F5E00D8DF7C As DateTime) Then 'True' Else 'False' End -- 0X00009F5E00D8DF7C Will be the value I get in VB.NET When I convert it Date.Now() To Hex

I'm trying to create an auction site using asp.net. My auction's start date & time and end date & time are stored in my sql server 2008 r2 database as datetime types. I'm using vb.net. I'm trying to create a select statement in which I can query the date and time portion relative to the current date and time (so as to only display current ongoing auctions). I can successfully query the date portion using the Date.Now function, but the time is giving me a hassle. DateAndTime.Now doesn't work. I've even tried to separate the time and date in the database, but I still can't get an effective query. Here are two examples of code which I've tried:

I've a scenario where I've to move data from a Oracle Table to a SQL Server table. The column in Oracle is Timestamp(6) 6 being the precision. Now I cannot send the Oracle Data in string format. I pull the data straight from the Oracle Table, so cannot format it on oracle side. What I can do is format the data using VB6.Format to make it suitable for SQL Server DateTime. I'm doing this for Oracle Date to SQL Server Datetime
