What is the significance of Counters in Replication (SQL Server)?

Hi Kumar,
SQL Server has about 150 different counters which can be enabled to measure system (database) performance. You can get lots of information regarding performancing monitoring and tuning including using counters at : www.sql-server-performance.com for example.
You set counters to measure things like page faults per second or user connections etc etc
Cheers,
Kevin

INSERT titles (title, cost)
VALUES ('testing', '35')
why SQL statement above can work? since the 35 is interger and not a string, so shount not be include '' for interger value....

Sure it works
u can add values as integer too (for integer filed)
ur example works as this:
INSERT titles (title, cost)<br />
VALUES ('testing', 35)<br />
|
|
|
|
|
i know, because i test before..
but i don't know why i can work....

how to change SQL statement below to use CASE instant of "AND" "OR" after condition where :-
ALTER PROCEDURE dbo.authorInfor
@au_lname varchar(40)
AS
select title, price, Name = substring (au_lname, 1,40), type
from authors a, titles t, titleauthor ta
where a.au_id = ta.au_id AND t.title_id = ta.title_id AND(au_lname = @au_lname OR au_lname = '' OR au_lname is Null)
Thanks.

If AND OR works use it; its must more efficient than using case.

CASE is generally used in instances where you want a different field value returned based on specified conditions. Your select statement is only concerned with returning all fields based on certain conditions. In other words, CASE wouldn't be used in the WHERE clause of an sql statement such as yours.
You could clean this up a little though, like this:
select title, price, Name = substring (au_lname, 1,40), type<br />
from authors a inner join titleauthor ta on a.au_id = ta.au_id inner join titles t on ta.title_id = t.title_id<br />
where au_lname = @au_lname OR isnull(au_lname,'') = ''
Or your where clause could be like this:
where isnull(au_lname,'') IN (@au_lname,'')
Other than that, nothing comes to my mind.

no wonder i can't get what i want if i change the predicate to use "CASE" in my SQL statement
can see that your SQL statement is more simplify and better than mine 
but 1 of my condition is when user do not insert any value for author's name, all author's name record will display in my result..
if using your SQL statement above, if i insert null for my author's name, then the result is empty..

I get a SQL statement that can use CASE under my condition
Declare @au_lname char(30)<br />
<br />
Select @au_lname = ''<br />
<br />
select title, price, <br />
Name = substring (au_lname, 1,40), type<br />
from titleauthor ta JOIN authors a on ta.au_id = a.au_id<br />
JOIN titles t on ta.title_id = t.title_id<br />
<br />
Where 1 = <br />
Case<br />
When RTRIM(@au_lname) = '' Then 1<br />
When RTRIM(@au_lname) <> '' And <br />
RTRIM(UPPER(@au_lname)) = RTRIM(UPPER(au_lname)) Then 1<br />
Else 0<br />
End
it's cool

I would like to write a simple inventory application in C# to keep track of my dvds, music and books. While I'll use this application, I am more interested in it for the opportunity to familiarize myself with accessing a database in C#. However, my knowledge about databases, particularly accessing them in C#, is limited.
I am looking for suggestions on a good way to set up this application and databases. Tutorials, code snippets or full blown applications that access a database in a way similar to what I would be doing are all helpful.
Thanks for any help / suggestions you can give.

I typed "ADO.NET Tutorial" into a search engine and got this: http://www.csharp-station.com/Tutorials/AdoDotNet/Lesson01.aspx[^] There are more tutorials out there if you care to look. There are also excellent books on the subject.

Thanks for your help!
I've been looking through the example at the site you suggested and I am having a little trouble getting it to run. I've installed "Microsoft SQL Sever 2005" and am trying to run the code from lesson 2 (http://www.csharp-station.com/Tutorials/AdoDotNet/Lesson02.aspx). When it gets to the "conn.Open()" call, I get an exception, which says:
"An error has occurred while establishing a connection to the server. 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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)"
I have attempted to resolve this but am not sure what needs to be done. I cannot find a setting that specifically allows or disallows remote connections.

It means you are trying to access the SQL Server over a network connection. By default, for security, the SQL Server 2005 only permits local connections (Previously TCP/IP was also turned on).
If your SQL Server is installed on the same machine as your application is running then change the Data Source value in the connection string to (local), with the brackets, instead of the machine name, an IP address or localhost.
If your SQL Server is running on a different machine to your application then allow it to accept incoming network connections (Open the SQL Server Configuration Manager). Find "Client Protocols", and in the right side Enable "TCP/IP". If you take this option you may wish to check the properties of the TCP/IP connection and ensure the port is locked down on your internet connection's firewall.

Hi all,
Here's where I am stuck:
I am planning to have a sitemapath or a treeview of available reports for users in SQL reporting services 2005. I am pretty sure it is not an easy job. I am thinking of using frames here. Let's say the left frame shows the treeview and the right frame contains the reports page. Assume, there are three folders (Folder A, B, & C) containing few reports each. I want these folders and the corresponding reports(preferable) to be present in the left frame as treeview. And when I click on the folder from the left frame, it should bring up the corresponding Report Manager page showing the folder contents in the right frame.
any help or ideas would be greatly appreciated!

I've got a dynamic SQL query that is generated inside a SP, and is run using the
EXEC (@SQL)
or
EXEC sp_executesql @strSQL
This has worked fine until now, where we are now using a database for unicode charachters.
All fixed code stored procedures return data correctly in the unicode format, however, all queries run using EXEC / sp_executesql, return '?' instead of unicode charachters.
This is a cause of some serious issues, and i'm really hoping someone knows if there is a fix for it!
Cheers

I am working with a datagrid in c#/asp.net. Within the datagrid I have to display fields from 10 different tables. I am wondering if my thinking of the syntax is correct.
First, the user enters the part number (Parts.PartNumber)which is actually a varchar. Then it finds the Part.ID. This Part.ID is what most things are going to inner join. Right now I have it just displaying the cost:
Select cost from costs c INNER JOIN Parts p ON c.PartID = p.Id where p.PartNumber = @PartID
But I want it to also display SubParts.Quantity where SubParts.PartID = Parts.ID. So would I set it up like this?
Select cost from costs c, quantity from SubParts sp (INNER JOIN Parts p ON c.PartID = p.ID AND INNER JOIN sp.PartID = p.ID) where p.PartNumber = @PartID
I've got a bunch of these so if someone can point me in the right direction much thanks!
