Hi Everyone,
I'm application is throwing this exception, and I cant really determine the cause:
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Data.OleDb.OleDbException: Unspecified error
at System.Data.OleDb.OleDbConnection.ProcessResults(Int32 hr)
at System.Data.OleDb.OleDbConnection.InitializeProvider()
at System.Data.OleDb.OleDbConnection.Open()
I don't get it all the time, it's actually very rare. It's happened about 2 times. It seems to me like the application has a problem establishing a connection with the database ... but I don't get why this would only happen sometimes.
My application uses an Access database that is constantly being accessed while using the application.
Anybody know how I can remedy this?
Thanks,
Tommy

That's a pretty vague error message. If I were you, I'd put a bunch of try catch blocks in there and try to get more information from the exception by popping up message boxes or printing the exception information into a log file or something. If the exception gives you a line number reference to your code at least that would be a place to start. Without more info...who knows what the underlying cause is.
Hope this helps.

How to copy database design of a table into another table without copying its values

.NET- India wrote: How to copy database design of a table into another table without copying its values
If you want to do this manually, you can do this through Management Studio by right-clicking a table and selecting 'Script Table As... -> CREATE TO'.
If you want do do it in code, you could use SMO[^] to obtain metadata for a particular table and create another table based on this metadata.

You could also
Select * into [NewTable] from [ExistingTable] where 1=0

When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 40)
i keep getting this error in the Application Log of the event viewer...
I have tried everything like changing the settings in SQL Server Surface Area Configuration...but am still getting the same error..
Am actually making a Windows Service that wud check the database for A DateTime field and if the entry in it matches the System DateTime it wud send an email to the person corresponding to whom this DateTime entry is in the database..
Please help me....
Thanks!!!

3 quick thoughts:
1: Did you restart the Sql service after making the changes to the surfacey widget?
2: Have you checked users/permisions?
3: Is your connection string correct? (Using the server tab in VSxxxx) Can you connect to the database?
Sorry if you've already done these.

The CONVERT function has a number of options for different date formats. Read the documentation and choose the most appropriate format for your requirements.

If you are converting these dates for display purposes, you are much better to do it in your UI code.

Top 2 on what basis? What is the rule to define which way the records are sorted?

Top2 based on each categoryname..........

Then the result you have shown does not match the data in the table.

I m facing a problem in this query
select a.eventid,b.name,convert(nvarchar,c.assigndate,106)as assigndate,<br />
convert(nvarchar,a.eventdate,106)as eventdate,a.event,a.details,a.eventtype from event as a left outer join emp <br />
as c on a.eventid=c.eventid left outer join user_info as b on b.userid=c.userid <br />

convert(nvarchar,a.eventdate,106)as eventdate,a.event,a.details,a.eventtype from event as a left outer join emp <br />
as c on a.eventid=c.eventid left outer join user_info as b on b.userid=c.userid <br />
WHERE a.eventdate > getdate()<br />
AND (<br />
(a.eventtype = 'Single Month' and left(convert(varchar,getdate(),102),7) = left(convert(varchar,edate,102),7))<br />
OR (a.eventtype = 'All Month')<br />
)
