Hi,
Use this query...
select id ,ord_num, ord_Date
from <table_name>
where ord_num = (select max(ord_num) from <table_name> where ord_Date =(select max(ord_Date) from <table_name>))

I know this question doesn't really fit here, and should probably be asked of some db admin types on another site, but I don't know of any such sites/people, so I thought I'd give you guys a shot...
I have an ASP.Net web service backed by SQL Server 2005 Standard happily running on a server hosted in or near Canary Warf. It's been up for 6 Months, with no down time except for scheduled maintenance. However, I've finally gotten funding to do what I wanted to do in the first place, and replicate the whole she-bang in a completely different part of the country, just so that when the inevitable happens (such as a builder cutting through the internet pipe at the host) the service can continue running with the minimum of fuss.
Whilst I can quite easily manage keeping the ASP.Net side of things in sync (unless anyone knows how to have IIS do this for me?), keeping the two databases synchronized might be more of a challenge.
Now I understand SQL Server has all manner of features that can do this kind of thing, but I'm googling around without really knowing what to google for. Database Mirroring keeps coming up, but I'm not sure if this is what I want - is it? Or is replication what I should be looking for (having read about the publisher/subscriber model, I'm unclear how we'd be able to get stuff back from the backup database on to the primary, once the primary has recovered)?
Cheers,
Martin.

Yup - mirroring is what you want. This[^] article is a good start.

Cool - cheers!

INSERT INTO `pic_newsletter_email_addr` VALUES ('', 'foo@foo.com')
It's a string sent into this function:
<br />
Public Function query(ByVal query_str As String)<br />
Dim query_ole As Data.OleDb.OleDbCommand = New Data.OleDb.OleDbCommand(query_str, conn)<br />
Return query_ole.ExecuteReader()<br />
End Function<br />
I am connected to the Access database. The error I get is "Data Type Mismatch in criteria expression"
*Edit*
The first field is an auto number and the second field is a text field with a length of 255

It's telling you that at least one of your parameters is the wrong type. I would suspect that it's the first one - I'm guessing that you are using an autoincrementing column here. If so, you should really write your query out with an explicit definition as in
INSERT INTO pic_newsletter_email_addr (column2) VALUES ('foo@foo.com');

How cool that I could guess this without even seeing the code - not that I've ever hit this problem before.

I want to take an IP address e.g. 111.222.333.444 and convert it to either a float or an unsigned datatype.
Thanks,
|
|
|
|
|
Why? An IP address is really a string of numbers - not a number. Removing the dots won't help because you really don't know where to put them back. I suppose you could always store it as four numbers, but it still doesn't gain you much.

The reason is for faster search indexing. I found this after I posted;
Create FUNCTION [dbo].[Dot2LongIP]( @IP VarChar(15) )
RETURNS BigInt
AS
BEGIN
DECLARE @ipA BigInt,
@ipB Int,
@ipC Int,
@ipD Int,
@ipI BigInt
SELECT @ipA = LEFT(@ip, PATINDEX('%.%', @ip) - 1 )
SELECT @ip = RIGHT(@ip, LEN(@ip) - LEN(@ipA) - 1 )
SELECT @ipB = LEFT(@ip, PATINDEX('%.%', @ip) - 1 )
SELECT @ip = RIGHT(@ip, LEN(@ip) - LEN(@ipB) - 1 )
SELECT @ipC = LEFT(@ip, PATINDEX('%.%', @ip) - 1 )
SELECT @ip = RIGHT(@ip, LEN(@ip) - LEN(@ipC) - 1 )
SELECT @ipD = @ip
RETURN ( @ipA * 256*256*256 ) + ( @ipB * 256*256 ) + ( @ipC * 256 ) + @ipD
END
RETURN @ipI
END
This does speed it up and seems to meet my needs.
Thanks,

Are the rest of the values on the row different like this? Are you just trying to get a list of DISTINCT ColumnA values?
ColumnA ColumnB
-----------------
123 ABC
222 ABD
123 ABF
222 SDS

Use a SELECT DISTINCT query to fetch unique values from a table.

Hello,
I have been working for two weeks on a problem to get data out of a database in a meaningful format. The database consists of basic server information along with information on some users, websites, and applications. The database structure is as follows:
Tables: Server Users Applications WebSites
Fields: ServerName ServerName ServerName ServerName
IPAddress UsrName AppName SiteName
Alive
ADsPath
dateAdded
datePwdChanged
I am trying to build a query/report that will give me information in the following format:
ServerName1 IPAddress Alive ADsPath dateAdded datePwdChanged AppName1 UsrName1 SiteName1
AppName2 UsrName2 SiteName2
AppName3 UsrName3 SiteName3
AppName4 SiteName4
AppName5
ServerName2 IPAddress Alive ADsPath dateAdded datePwdChanged AppName1 UsrName1 SiteName1
AppName2 UsrName2 SiteName2
AppName3 UsrName3 SiteName3
AppName4
and so on. (Tried to get the formatting right on here, but not sure it displays completely accurate).
So far, I get either a query showing servernames multiple times with multiple application, user and site entries or I get nothing.
I have googled everything I can think of and have run out of places to look. I have tried googling on what I want it to look like, how I think it should be queried, all to no avail. Obviously, I would be grateful if someone had a magic bullet for this, but at least pointing me in a new and valuable direction would be hugely appreciated.

Use a table (fixed or not) to keep this report-like data and populate it using a stored procedure.

I am assuming that I would need to create a one-to-one column relationship with the server table columns, however, for the apps, users, and websites, would I create a memo/text field and then concatenate all of the entries to show in there?
I am not as familiar with the intricacies of SQL and using stored procedures to get something like this done.

Hi Jon
Your problem can most-easily be solved at a presentation-level, rather than at a SQL level. Under MS-Access, you would define a report that lists just your servers. Then embed 3 sub-reports (for each of your other tables) linking to the server. Most other reporting tools offer similar sub-report facilities.
If you do need to solve it using SQL-Server then your will need to use a stored procedure and a bunch of cursors.
Regards
Andy

Actually, this makes much more sense. I don't have to do it in SQL. I just need the information in a format that is easily read and makes the most sense for the project.

Hi,
How do I get the diagrams to print smaller on a page? It's those diagrams that display the tables with their relations to other tables. Currently the tables are printed huge and there is a lot of white space in between.
Are there any better 3rd party tools that can create better diagrams?
Regards,
Brendan

Have you tried rearranging them closer together?

Hi,
I have searched Google for performance tips but didn't find many because I didn't understand. If any one has a good readable topics please forward it to me.
If I changed int to smallint can this also result in better performance?
Thanks
Brendan
