These multi-date/multi-value ones can be a bit tricky.
One solution is this: (and it assumes that each employee only has a single entry for any given date)
create a view, called vwEmployeeMaxDate that contains the following:
select ID, max(EDate) as MaxDate from TABLENAME
group by ID
Secondly, to get the information you want above, use the following query:
select TABLENAME.ID, TABLENAME.Value1, TABLENAME.EDate
from TABLENAME inner join vwEmployeeMaxDate on (TABLENAME.ID = vwEmployeeMaxDate.ID) and (TABLENAME.EDate = vwEmployeeMaxDate.MaxDate)
brackets not necessary, but used for emphasis of the two parts of the join.
Hope this helps.

Hi blue boy,
Some times the value wil go decrement also...,
So we cant say max(value),
then it will be give wrong o/p,

I am currently having problems with the SQL Server 2005 Developer.
- I have a Windows XP SP2 Japanese version.
- This machine is connected to a domain managed by Linux server.
- I login with a domain account and install.
Initially, the intallations were failing with an error message that I do not
have administrator right.
We created an account on my machine with the same user name as that used
for the domain, and gave this administrator rights.
With this the installation was completed. However, there is another problem,
I cannot connect to the SQL Server.
For the installation, I chose "Local System" with Windows Authentication,
but the connection to the database still fails with the error message that
remote connection is not supported. I do not understand why I need TCP to
accesss a local installation of the SQL Server.
However, I followed the procedure outlined in a MS KB to enable TCP. But the
connection to the database still fails.
I am using the Management Studio to connect to SQL Server. I have also tried
creating a database in VS. NET 2005 and this also fails. I have checked the
services and all are running.
What is wrong and what can I do? (it takes more than an hour to install this
stuff and it is really consuming my time). Any help?
Best regards,
Paul.
Jesus Christ is LOVE! Please tell somebody.

By default only local machine administrators have rights to connect to SQL Server. You need to add your Windows user account as a login in SQL Server, then assign it appropriate rights, if your domain user account is a standard user on the local machine.
To make it the equivalent of the Administrators group login, make your user account's login a member of the sysadmin server role.

I am unsure about how to code in SQL the following select procedure. I have a list of companies, around 500, and I want to display them in a usefull way on my site. I have proposed a A-D E-H I-L etc system where the user can select just a chunk of the alphabet to display. Therefore I am going have some form of range parameter that I will be adding to the SQL query.
What would be the best way to create this code in a modular fashion so that I could fire different variations of ranges at it without having to pre set them all up.
I would guess the code would ustilise the LIKE keyword with a wildcard after it but how would I create the prefix. I have never heard of any Alphabetical objects in SQL.
Any help would be greatly appreciated. Thanks

You could have a computed field that contains just the first letter, then query for range letters off that computed field.

Sorry I don't follow this. Could you explain, possibly using some code, this solution in more depth.
I really want to be able to pass a parameter of say "AD" and then create some code that could work out the rest of the letters needed and then perform something like the following.
SELECT *<br />
FROM SOMEWHERE <br />
WHERE nameofperson LIKE a%<br />
AND nameofperson LIKE b%<br />
AND nameofperson LIKE c%<br />
AND nameofperson LIKE d%
|

Hi Sam
Assuming that you are using SQL-Server, try:
select * from somewhere where nameofperson like '[ABCDEF]%' You might want to check that you have a case-insensitive collation set for your database - otherwise you will need to use the "Upper()" function around your "nameofperson" column.

Hey good work, it works. I didn't think it would be that simple. Turns out it does pull both lower and uppper case records as well. Thanks for your help.

Andy's solution is a very good one

Yeah i think it kind of trumps yours for the fact that I can skip letters out in the way he proposes. Thanks for your solution though. It does indeed produce the results I require.

Andy's works fine as long as you aren't asked to do something like A-Q

Here is what I was thinking of:
SELECT * FROM sometable WHERE ( Left( someField,1) >= 'A' AND Left( someField,1) <='D' )
This would return all rows in sometable where the first letter is A, B C, D. To do something like AD, you could just have this query in a stored procedure and have it parse your parameter A and D in this case, and plug it into the WHERE clause...

Good day.
I'd like to add "fuzzy search" functionality to my application.
"Fuzzy search" in this topic means selecting (from DB table) rows, which have "fuzzy search" coefficient (calculated using etalon string) not less some_predefined_const. Fuzzy search coefficient calculating algorithm can be various.
So with etalon string "Margaret" "fuzzy search" can find "Nargaret", "Margoret", "Margret" etc.
IMHO time to develop, test and tune code must be quite long. I prefer to buy such "fuzzy search" component.
Does anybody know where can I get such component - server version (SQL 2005) or client version (.NET)?
How much can such component cost?
Thanks.

I have a DataSet which has Two tables: TableAll, TableQueried
TabelAll has all data available.
What I want is to use a command to select only those rows in TableAll and copy them to TabelQueried which are LIKE some pattern.
I knew how to do this when I had a database and used connections; but now there is no database.
How should I do anything like this command:
"SElECT * FROM TABELALL WHERE Data LIKE [pattern]"

I assume you are talking about an ADO.NET way?
If so look at DataTable.Select(CriteriaString).
I think the select method has an override for an order by clause. Criteriastring is a string in the format of:
(column name) expressions such as = or like or in; google datatable.select to get list of expressions. And then the criteria, very similar to a where condition in a sql statement.
IE for examaple
DataRow[] rows = myDataTable.Select("Column1 = 25","column1 asc")
This will return an array of DataRows which you can then work with.
Hope this helps!

THANK YOU!! 
You really helped me out! ![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)
I was JUST looking for this.

The only caveat you need to remember is that the datatable select consumes quite a bit of memory as it has to go through every record in the table. Be sure to set a primary key column and index if possible.

Is there any way to view next or previous data of SQL database without using SQLDataAdapter and DataSet. If there is then how?? And If there is no way then what's the procedure of using these two thing?

Why do you want to not use DataAdapter or DataSet? Any particular reason?

The SqlDataReader can only present a forward-only, read-only result set. This is a change from the old ADO Recordset days mainly because the programming model tended to lead to applications holding result sets, and hence transactions, open for a long time and blocking each other. ADO.NET offers a disconnected-only model to avoid these problems (if appropriate, a provider can offer a connected model, for example SQL Server Compact Edition, which is an in-process database engine, offers the SqlCeResultSet class which provides scrolling and updateable result sets).
The normal approach is simply to construct a SqlDataAdapter object, set the SelectCommand property to a command object with the appropriate command, then call Fill on the data adapter to get the results.
If using data binding of Windows Forms controls, the CurrencyManager class can help manage the current position in the DataTable or DataSet.
