You need to add your table name to the query:
SELECT DATEDIFF(second, f3, f2)
FROM your_table_name_here

Thanks Jon, I have been staring @ this stuff for 36 hours...That is a key indication I need sleep.
Thanks for answering my gross oversight.

I am trying to figure out the most efficient way to obtain and present a set of information....
I have a SQL table with information that is related to account numbers. There can be multiple lines with the same account number. I have a list of account numbers in a spreadsheet (about 100). I would like to know if there is at least one record in the table whose account number matches the number on the spreadsheet.
Is there ane efficient way to give me a yes/no or other info without hitting the database 100 times? It could be done in Excel or VS2005. Does anyone want to throw out a suggestion?
Much thanks in advance.

select count( accountnumber ) from table<br />
where accountnumber in ( a, b, c )
That will tell you the number of accounts that match, where a, b and c (and so on) are account numbers.

|

This would give me the number of accounts that match, but not which of the accounts match....correct? I am needing to figure out which of the numbers match. Thanks.
|
|
|
|
|
select distinct accountnumber from table<br />
where accountnumber in ( a, b, c )<br />

After installing SQL Server 2005 Express, I find that I cannot view database diagrams from an MSDE database. After some more poking around the internet, I discover that diagrams have been completely removed from SQL Server 2005!
Is this true, or have I entered the Twilight Zone?

That is incorrect. The diagraming facility in SQL Server 2005 has changed. You cannot open SQL Server 2000 diagrams in SQL Server 2005 Management Studio. You can create new diagrams, however, I don't know if it will allow them to be written to a SQL Server 2000 database.

As Colin states, there is diagramming available in Management Studio, but it will not allow you to create new diagrams in a SQL 2000 database. It relies on too many things that aren't present in SQL 2000, and when you first create a diagram in a 2005 database it asks you if you want to install the diagramming extensions.

Hi All,
I wanted to use the undocumented SP sp_MSForEachTable to selectively delete data from tables. So in short i want to achieve something like this using sp_MSForEachTable.
delete from TableName where Date = '2007-01-03'
I looked at various queries on the internet using sp_MSForEachTable, but was not able to find out the usage of sp_MSForEachTable with a "Where" clause, so if anybody has the query or links request to post it here.
All that I found was to delete all data from all the tables in the db.
I tried using the @whereand option like this, but the got an error saying Invalid column: SomeDate. I have this column in all the tables in that database. I did a quick check looping thro all the tables using cursors and that works fine.
EXEC sp_MSForEachTable @command1='DELETE FROM ?'
,@whereand='and SomeDate = "2007-01-15"'
Thanks.

Sir/Madam
I am Final Year Engineering student. I want to get information about connection of computers at different cites.
Actually if I want to computerize a department of any company which have its offices at several cities then what steps I should follow.
Means how I can connect that no of computers in appropriate manner to get desired output.
I want to make it just like railway reservation system through in which if I enter data at same time then database must be able to prioritize data in sequence to enter in database.
Which database & platform or language I should use to code this kind of project.
Thank You

I've used an Access database for this purpose. The windows operating system will most likely already have the Jet database engine (which access uses) installed. If not you can require users to download MDAC in your program's setup/install package which is a small download compared to MSSQL, SQL Express or other full database engines. The downside is that Access is a relatively small database with not as much capability as other engines. But the projects I was doing were quite small.
Hope this helps.

That is really helpful. So what you are saying is when i need to distribute my program, i would not need to install a database engine on the clients computer?
|
|
|
|
|
Correct. You will only need to make sure that they have MDAC installed and if not, then install it. But the install is under 6 MB and most computers will already have it installed. Windows XP SP2 already has it, for example. I can't remember what service pack Windows 2000 has it.
In any case, it is pretty easy to require MDAC when you are creating an install program with Visual Studio 2005. You just right click on the project icon in the Solution Explorer. Select Properties. Click the Prerequisites button. And make sure that Microsoft Data Access Components 2.8 is checked in the list. And if you want the user to be able to just install the MDAC without having to go to Microsoft's website I would recommend selecting the "Download prerequisites from the same location as my application" option.
Also, remember that if a user happens to have microsoft access on their computer, they can access your database through that. So you may want to put a password on it to make sure they don't change things/mess up your schema.
Hope this helps.

Yes, your help is much appreciated.
Somebody else suggested programs like Microsoft Visual Fox Pro, but I had doubts about the availability of them, well from the users perspective at least.
Once again thank you very much for your help.

if it's SQL Server you can use:
<br />
select table_name<br />
from<br />
information_schema.tables<br />
if it's Oracle you can use the meta data views, like:
<br />
select *<br />
from<br />
user_tables;<br />

You would add 49 days to the first date to get the second date. I'm not being funny here about the syntax, because the exact syntax differs between databases.

Actually you don't. You get the data exactly as it was put in to the database. Multiple lines and all. The problem is the way browsers render HTML. They view your text as HTML and in HTML a carriage return or newline character does not signify a new line. You must replace the newlines with <br/> in order to be formatted properly in the web page.
So, this becomes an ASP.NET problem, not a database problem.

what is the difference between Layred Arctitecture and Non Layred Arctitecture?

A layered architecute separates the database from the business logic from the presentation of the information.
A non-layered architecture is sometimes pejoratively called the giant ball of mud architecture. And for good reason, in all but the smallest of projects the code in a non-layered architecture will event resemble a giant ball of mud. Finding anything in that ball of mud becomes increasingly difficult.
