thanks for your help.![Rose | [Rose]](https://codeproject.freetls.fastly.net/script/Forums/Images/rose.gif)
Now I have a query that if I want find 3rd highest or 4th highest salary then how to write query?
thanks!
|

|
|

select TOP 5 salary,empID
FROM EMP
Order by Salary DESC
Use this to find whatever number of top salaried personeel u want. Use a Cursor to fetch the records one by one. In this way u can ignore the records you dont want. Like for finding the 4th highest salary you can ignore the 1st 3 records and get the fourth one.

No need to use a cursor. Here is a query to get the fifth salary.
SELECT TOP 1 Salary, EmpId
FROM
(SELECT TOP 5 Salary, empID
FROM EMP
Order by Salary DESC) AS TopSalary
ORDER BY Salary ASC

I have an ntext column in a table. I wanted this column value to be uploaded to a text file. I was using some code of my own, but it is not working out.Does anybody has any pointers on this? Any simple method to do this programmatically would be highly appreciated. I need to pull this code in one of my button click event on a windows page.
Thanks in Advance!

I am trying to create a reporting system which will give me the "Customer ID", "Number of Messages sent", "Is Message a part of a thread or Distinct", Message Status (i.e. New, Under Review, Cancelled or Resolved) within a given period. I honestly do not see no need for a curso in here but I believe one can be used but I do not understand the benefit of using one. The search is working fine except for the last "Select" prior to dropping the table is not providing Distinct User's. Users with multiple messages/Threads are being pulled up as many time as the amount of records found for them. It is the result set from the Last select that is displayed in the GUI.
Any assistance given will be appreciated.
SET NOCOUNT ON /* Don't return row counting to caller */
CREATE TABLE #MS_MessagesFromCustomer(
NumOfMessages BIGINT,
CustomerID VARCHAR(100),
Period datetime,
ThreadID int,
MessageStatus int
)
CREATE TABLE #MS_InquiriesByCustomer(
ThreadID int,
CustomerID VARCHAR(100),
TotalMessages int,
New int,
UnderReview int,
Cancelled int,
Resolved int,
TotalThreads int
)
Insert into #MS_MessagesFromCustomer(CustomerID, NumOfMessages, Period, ThreadID, MessageStatus)
Select MSM.SenderID, count(MSM.MessageID)Messages, Convert(varchar, MSM.SentDate, 101) [Sent Date],MSM.ThreadID,MST.CurrentStatusID [Current Status]
from dbo.MS_Messages MSM INNER JOIN dbo.MS_Threads MST ON MSM.ThreadID = MST.ThreadID
where MSM.SentDate >'3/1/2005'
and MSM.SentDate < '3/31/2005'
group by MSM.SenderID, MSM.SentDate, MSM.ThreadID, MST.CurrentStatusID
order by SenderID
--Select * from #MS_MessagesFromCustomer
INSERT INTO #MS_InquiriesByCustomer(ThreadID,CustomerID, TotalMessages, New, UnderReview, Cancelled,Resolved, TotalThreads)
Select Distinct(ThreadID)'ThreadID', CustomerID'Customer' , count(NumOfMessages) 'Total Messages Recevied',COUNT(CASE MessageStatus when 19 THEN MessageStatus end) AS 'New',
COUNT(CASE MessageStatus WHEN 20 THEN MessageStatus end) AS 'UnderReview',
COUNT(CASE MessageStatus WHEN 21 THEN MessageStatus end) AS 'Cancelled',
COUNT(CASE MessageStatus WHEN 22 THEN MessageStatus end) AS 'Resolved',
(COUNT(CASE MessageStatus WHEN 19 THEN MessageStatus end) +
COUNT(CASE MessageStatus WHEN 20 THEN MessageStatus end) +
COUNT(CASE MessageStatus WHEN 21 THEN MessageStatus end) +
COUNT(CASE MessageStatus WHEN 22 THEN MessageStatus end)) AS 'Total Threads'
from #MS_MessagesFromCustomer
group by customerID, ThreadID
order by customerID
SELECT Distinct(CustomerID),* FROM #MS_InquiriesByCustomer
Select * from #MS_MessagesFromCustomer
Select Distinct(CustomerID), TotalMessages 'Total Messages Recevied', New 'New', UnderReview 'Under Review', Cancelled 'Cancelled',Resolved 'Resolved', count(TotalThreads) 'Total Threads'
FROM #MS_InquiriesByCustomer
GROUP BY customerID,ThreadID, TotalThreads,TotalMessages, New, UnderReview, Cancelled, Resolved
ORDER BY CustomerID
DROP TABLE #MS_MessagesFromCustomer
DROP TABLE #MS_InquiriesByCustomer

If you knew it would not compile why didn't you tell me?!?!?!

DISTINCT used as an argument of a SELECT clause does not eliminate rows due to a single duplicate column. It eliminates rows when all columns are equivalent. The whole row would have to be the same for it to begin its removal process.
DISTINCT can be used as an argument in an aggregate like AVG(DISTINCT price). Here it will eliminate duplicate prices before calculating the average.
I think you need to re-examine how you have coded your store procedure. It seems a little over done. Not sure what your desired end result is but, I would think a much simpler LEFT JOIN would handle most of the work.

Hellow everybody
I want a query that will return number of rows in the database , but it will take three parametes from the calling method.
I implemented a query which is as follows:
Select Count(*)
From MainRecord
Where (MealType = @MealType) AND (ID = @ID) AND ( CAST(FLOOR(CAST(DATE AS FLOAT)) AS DATETIME = @DATE)
The purpose of this query is that I want to count number of rows if the ID, MealType and DATE are in the database. Also, the @DATE I am giving in the calling query is now date which is for example ( today date [08/23/2007 00:00:00]). I wanted to be checked with the date that is stored in the database where the DATE that is stored in the database is DATETIME which is in this form (08/22/2007 13:14:50). Therefore, the CAST(FLOOR(CAST(DATE AS FLOOT)) AS DATETIME will convert that datetime to (08/22/2007 00:00:00) so we could compare then just in the date.
I don’t know if this way is right or not and if not how can I do it.
Thaanks,

Did you mean FLOAT?

Have you tried experimenting? Building up a part of the query to see if it does what you want?
SELECT GETDATE()
SELECT CAST(GETDATE() AS FLOAT)
SELECT FLOOR(CAST(GETDATE() AS FLOAT))
SELECT CAST(FLOOR(CAST(GETDATE() AS FLOAT)) AS DATETIME)
Looks like it works to me.

Yes, I mean foat. Does this way logical and it will work properly. If there is an other way i can try especially to check the time.

There is another way to check the date.. try this..
Select * From ....
Where
Convert(DateTime, @ParameterDate, 103) = Convert(DateTime, GetDate(), 103)
This is for checking with current date(GetDate()). For more precision yo can add the following lines of code with the above code.
And Year(@ParameterDate) = Year(GetDate())
And Month(@ParameterDate) = Month(GetDate())

I presume you are talking about a DataTable rather than one in SQL Server.
foreach(DataRow row in myDataTable.Rows)
{
}

Hi everyone,

Thanks

If you use Server Authentification use the name of your computer ,the user "sa" and the password that you set to sql server during the installation.

Im using of:
Server type: Database Engine
Server name: "I dont know what is it"
Authentication: Im trying with "Windows Authentication" and also Sql Server Authentication with sa" but I got this error:
Im trying with your answer(sa) but I got this error:

It is the name of the machine, or "(local)" for the server on the machine you are using. If you installed a named instance (something you would have to do explicitly) then you will have to add /InstanceName after the machine name.

No, not "local". You need "(local)" with the brackets.

Are you trying to connect to a SQL Server running on a separate machine?
If so you have to enable TCP/IP on the server. Use the SQL Server Configuration Manager

Depends.
If it's installed on your local machine with Windows Authentication:
Server = localhost - or if you're using Sql Server Express localhost\SqlExpress or if you named an instance during installation SqlExpress\TheNameYouChose (or just uninstall and do it again properly).
If you installed it locally, but used mixed mode authentication:
user name = sa
password = whatever you set it to be.
If you installed it on a networked machine:
I can't help you here.

I dont know why I cant see any servics of sql server on the services?
|
|

|

You can connect to your local server by using "." Just type the "." in the name field and then login using credentials either "windows" or SQL.
Hope this helps.
Thanks!

I jsut moved to a company that uses Oracle for almost all their database stuff. Having never used PL/SQL and being used to SQL server, I'm on a bit of a learning curve. Even though I'm a decent T-SQL programmer, there's a bit to pick up, and I need to be productive quickly.
I reckon I need two things ;
A step-by-step introduction book, with real-world worked examples and the like, to get me going and give me the knowledge I need to do the job as quickly as possible, and;
A small reference guide to the PL/SQL language, to have at my desk 24/7 for when I need specific, indexed information on a subject.
Has anyone had any experience with Oracle or PL/SQL literature? Any recommendations?
All the dude ever wanted... was his rug back.
