Hi
select CAST((datediff(day,createdon,getdate())/30) as float) Avg, from customers
I want to give the result in Fraction is it possible? it is not showing the fraction result.
createdon is the datetime field
Any Help is appreciated.
Regards

datediff function's date part "day"
returns difference in number of days i.e 1 / 2 / 3 .....
if u r looking for even part of day, get the difference in hours/minutes/ ...
then try converting that to days so that you get the result as you are expecting
Regards

You can use a cursor to do something similar to a for loop, but it is very slow compared to a single update statement. I would suggest you think seriously about using a single update statement instead.

Thanks Ben..
but I think on that method :
I want to gove some records a serial >> like 1,2,3 ....
and I can't make that fields Identifier because the serial will be repeated again with another invoice ...
then I'd like to path all selected feilds and give every one it's serial ... from the first to the end ..
then if I user Update statement .. I can't know which record will take No 1 and which will take No 3 ...
I want by the for .. next .. to give all selected row it's serial ..
I know that is strange and there's another method to solve that .. but on my project now , I need this method ...
again .. I hope if any one understand what I mean
jooooo

Well, perhaps you should still look at using an update statement, but then using a scalar function. You could pass in some value you would help the function know what serial number to return. Just a thought.

Now I am trying to install sql server 2000 report services. But I run SQL2KRSSP1-ENG.EXE setup
Then following error occurs
The upgrade patch can not be installed by window installer because the program to be upgraded may be missing , or the upgrade patch may update a different version of the program Verify that the program to be upgraded exists on your computer and that you have the correct upgrade patch.

I have developed an application that connects to a SQL Server 2003 database. My connection string is stored in the application configuration file. In development it is connecting to our company server but when I installed the application on site it will connect to their own SQL Server 2007 database. So when I installed the application on site I went into the configuration file and changed the server name to the new name. Well, for some reason my application cannot connect. Is there an easy way to get the connection string needed to connect to the new database?

Is not out yet, so I assume you really meant SQL Server 2005.
For SQL server 2005, remote protocols (TCP, Named pipes, HTTP) are not enabled by the default installation.
Depending on what they have enabled (if anything) and how you were trying to connect, thing might very well not work that
worked fine with SQL Server 2000. In other words, there is likely nothing wrong with where you are storing the connection string,
but the protocol you are trying to connect with may not be active on their server (TCP for instance - dbmssocn).

Comment out the try/catch block and see what error is given then.

Lately I have be using Strongly typed datasets and adapters and have been liking them. However I have come across a few stumbling blocks that I was wondering if someone could help me with.
1. I'm making a code library that does various things, I guess you would call it something of a 'business layer.' I have strongly typed data adapters, with my own sql fuctions. In my library I use these data adapters and also enforce a few key rules like setting timestamps and logging user names. If someone could create their own instance of the data adapter and bypass my library it would threaten the integrity of the data. Is there some way to secure the dataset so that my libary would be the only thing that could create it?
2. Next thing, in my library each function creates a data adapter, calls its function or functions and then returns its value. Since it is a class I was looking at making a private static version of each of these data adapters. Are there any pitfalls that I should be aware of, (adapters not clearing data, or disconnecting, etc....) or is this a pretty common practice?
3. Lastly, is there some way to enforce rules into the data adapter itself. For instance if i have a function called "Add_Record(recorddata, username, timestamp)" do something to enfoce that username must always be "HttpContext.Current.User.Identity.Name" and that the timestamp is "datetime.now"

Well, either you are attempting to connect to a SQL Server that does not exist. Or the SQL Server does exist but you don't have the authority to use it from an ASP.NET application.
Check your connection string. Does the server exist?
Are you using a trusted connection?
* If yes, does SQL Server permit access to the ASP.NET account?
* If no, have you set up the relevant user in SQL Server? And Is the password specified in the connection string correct?
