the Access DB is used to only store data and it will be located in some shared folder on the network.
There's about 10 client apps (which is probably what you meant by "front end") that will, at any point of time, read data from the database and also write data to the database.
Forms will not be implemented in the database directly.

Access and SQL Server will both be fine as a back end then...

let us take the server is down and all the data are corrupted. other than backup,replication, log shipping what can we do to get back the data or make the customer to proceed with the work ?

Ah, but this time some of it is bold and underlined (I guess for those of use that were too dim to understand the first time).

I'm waiting for a reply, but I don't have a backup, and my response will be then you don't have a client!

With the convert function.

Hi Thanks For your reply ,
The thing is that i have one table in which date is stored in column(datataype nvarchar)
There are more than lacs of records in this table.
so i want to convert this field into following format
ORIGINAL FORMAT OF FIELD IN TABLE (DATATYPE:-NVARCHAR) => 30/11/2009
I WANT INTO FORMAT : 30112009
AND ANOTHE FORMAT : 30/11/2009(SMALL DATETIME)
Please help me out.
I tried the solution which you gave but its giving following error
"Msg 8115, Level 16, State 2, Line 1
Arithmetic overflow error converting expression to data type smalldatetime.
"
Please help me out
|

Not sure why you get this error.
declare @a nvarchar(20)
select @a = '30/11/2009'
select convert(smalldatetime,@a)
gives me 2009-11-30 00:00:00, which is correct. How it is displayed (i.e. 30/11/2009 or 30112009) is down to your format mask, SQL Server simply stores the datetime value as a number.
Please, before posting any more questions around this, use the F1 key and read up on date time data types.

What you said is very correct , i am not denying it. The thing is that i am inserting into destination column(smalldatetime) from source column(nvarchar) and the number of records are around 4lac.
I am inserting through sql script in query analyser. After insrting some 20k records it generates that "Arithmetic overflow error".
This was task given to me. thats why otherwise i could change my destination column to datetime. Its working.
But I am forcebly want it to smalldatetime as this was task for me.

Have you done any data analysis to make sure that all the values you are trying to convert fall into the acceptable range for smalldatetime values?
Perhaps you have a record (around the 20K mark) that has a typo in the date, and instead of 30/11/2009 it's 31/11/2009 (which isn't valid) or 30/11/9999...

So you have an invalid date in there. Use the isdate function to find any that are invalid.
declare @a nvarchar(20)
set @a = '30/11/2009'
select isdate(@a)
-- returns 1
set @a = '31/11/2009'
select isdate(@a)
-- returns 0
Its not rocket science.

You were correct there were dates in dd/mm/yyyy which were incorrect format according to ISDATE() function . So i converted it into mm/dd/yyyy format and it worked.
Now thing is that i just saved in date format only like '11/30/2009' but in table having column date (datatype smalldatetime) it stored like '11/30/2009 00:00:00.000'
I want to store only date (datatype=smalldatetime). Is there any way to store into sql server 2005 date column with date only excluding time.

No, as I said in an earlier post, sql server stores the date and time as a number, not in any format. Just use a format when you display it.

Thank you very much for your valuable response.

why would you choose smalldatetime when all you want to store is a date?

Questions such as this explain so much about the world we now find ourselves in 
|

From the discussion I gather that you are running up against the first problem of storing date data in a non date data format.
You have precicely 1 choice to fix this problem, change your data type to datetime NOW, if you use a work around to convert from nvarchar to datetime then you will always be performing that work around. STOP AND FIX YOUR DATA.
I suggest creating a new column in a datetime format and convert/copy the data to that field. You are already getting an error (arithmetic) so I know your nvarchar data is corrupt. I would recursively convert as much as possible and then manually update the rest.

How many recovery methods do you want? Restore the database from the last backup. This is the tried and true method of recovering from a complete database failure.

Type everything back in from scratch?

I am going through the msdn sql book and am running a very advanced query with a lot of sub-queries. In the book it does not explain the sub-queries in detail. It only shows the query and gives a result set. I am posting the query below so it can be seen. When I run it I am not getting the same results. First, I am not sure of the order of evaluation of each of the sub-queries (i.e. which get run first) and second I don't quite understand the table aliasing being used in the query. If some one could help me understand what is exactally going on, or point me in the right direction that would be great! Query below:
SELECT OrderID, CustomerID, EmployeeID, OrderDate, RequiredDate
FROM Orders AS o1
WHERE OrderDate = (SELECT MAX(OrderDate) AS Expr1
FROM Orders AS o2
WHERE (EmployeeID = o1.EmployeeID) AND
(RequiredDate = (SELECT MAX(RequiredDate) AS Expr1 FROM Orders AS o2
WHERE EmployeeID = o1.EmployeeID) AND (OrderDate = o1.OrderDate)
AND (SELECT MAX(OrderID) AS Expr1 FROM Orders AS o2
WHERE (EmployeeID = o1.EmployeeID) AND ((OrderDate = o1.OrderDate)))))))
I am not saying anything bad about the book but I am just learning advanced querying and someone who is an expert providing a little assistance would be great.
Thanks,
Steve

Is this what you were trying to do?
SELECT o1.OrderID, o1.CustomerID, o1.EmployeeID, o1.OrderDate, o1.RequiredDate
FROM Orders AS o1
WHERE o1.OrderDate = (SELECT MAX(o2.OrderDate)
FROM Orders AS o2
WHERE o2.EmployeeID = o1.EmployeeID)
AND o1.RequiredDate = (SELECT MAX(o3.RequiredDate)
FROM Orders AS o3
WHERE o3.EmployeeID = o1.EmployeeID
AND o3.OrderDate = o1.OrderDate)
AND o1.OrderId = (SELECT MAX(o4.OrderID)
FROM Orders AS o4
WHERE o4.EmployeeID = o1.EmployeeID
AND o4.OrderDate = o1.OrderDate)
I find it much easier to read if I indent the code and explicitly use table alias'. The intent of the sql becomes much clearer.
