Storing Oracle TimeStamp Precision 6 In SQL Server DateTime
Apr 20, 2011
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. Can something similar be done for timestamp and Datetime.

I need to begin working with milliseconds in .Net 3.0. The data will be returned from an Oracle Database and if I understand correctly Oracle can only store dates that use milliseconds as a TimeStamp. It does appears that the Date type in .Net can handle milliseconds but when I have tried to retrieve Timestamps from Oracle stored procedures in the past I ran into a nasty error. Can .Net handle the Oracle timestamp data type or do I need to bring it back as a VarChar and cast it to a date type?

I am located in the NorthEast US. My problem is properly storing a string in European date format (today is 23/1/2012).
For example the string '12/1/2012' is stored as as December 1, 2012 not January 12, 2012.
How can I dimension a DateTime variable to store the European date string properly?

I have Visual Studio 2008 running from Windows XP. Our server is Windows 2003 Server.
On a different server, there is an Oracle database we want to connect to.
I've made the connection work from my local VS instance using system.data.OracleClient with the following code:
Dim oradb As String = "Data Source=(DESCRIPTION=" _
+ "(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)" _
+ "(HOST=ourHostaHere(CONNECT_DATA=(SERVER=DEDICATED)" _
[Code].....
What do i need to do, to get my local Visual Studio 2008 project to connect to the oracle database?
What do i need to do, to get our server to allow the published .NET page to connect to the oracle database?

A VB.net program reads the queue and calls a stored proc in SQL Server that processes and then inserts the message into another SQL Server table and then deletes the record from the oracle table.
We use a DataReader to read the records from Oracle and then call the stored proc for each of the records. The program seems to be a little slow. The stored procedure itself isn't slow. The SP by itself when called in a loop can process about 2000 records in 20 seconds. But when called from the .Net program, the execution time is about 5 records per second.I have seen that most of the time consumed is in calling the stored procedure and waiting for it to return.[code]...

I used this way to make my shopping cart system :
Click here to see the example
when I add a product to the shopping cart it adds it very well but the problem is in the session, it stores it in the server not in the client browser.
so if some body visit the website from another computer he can see the added products on his browser while it should be empty.
Is there a way to save it on the client side instead of the server side ??

DATA, TYPE, FILE TYPE, SIZE, DOC TYPE

Is there a way to set session variables during login that are then available to reports? We have a reporting services server where we move and denormalize data from our transaction system for reporting purposes. In order to allow our users to login with the same user name and password from the transactional system we have set up custom forms authentication and after much trial and error it is finally working. In addition we have the authorization accessing our transactional system so that any changes in user authority is immediately reflected in Reporting Services.
Our problem now is that we would like to add some additional features such as locking down parameters depending on user authority/groups in our transactional system. We have found a way to do it but it's inefficient, basically we have stored procedures that will query our transactional system to check for access. The problem is that these queries will often be run for every report request even though the answer is unlikely to change. It would be nice to have access to session level data that can be set once during log in and then accessed from the reports.

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.
Private Function ConvertStringToDate(ByRef FileName) As Date
Dim S As String = FileName
S = S.Substring(4, 7)

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

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:
