Hi guys,
I have some place holder functionality in our Aata Access Layer that should return a properly sorted and paged subset of requested data. However, at the moment we do not have sufficient data to warrant writing the full blown stored procs to implement the most efficient sorting / paging.
However, i would still like to be able to return the correct subset of data in a data table. So how would i go about reducing the contents of the DataTable, whilst retaining the strongly typed data?
Cheers
Tris
Note: Using .NET 2.0

I would use a DataView and use The RowFilter property, as long as it is a small set. There is also sort functionality in the DataView as well.
Something like:
C#
DataView dv = yourDataTable.DefaultView;
dv.RowFilter = "column1 = '2'";
VB
dim dv as DataView = yourDataTable.DefaultView
dv.RowFilter = "column1 = "'2'";
Then you bind whatever control to the DataView
Hope that helps.

Hi Ben,
Thanks for the response.
I need to retain the strong type information of the origional table, basicaly as if the table had been populated origionaly from a pre-sorted and paged SQL query.
Cheers

2> go
But i got an error

Hi
Just attach existing database instead of restoring database. This is simple as you are not going to restore it... right ??
Harini

But I haven't got that database on my PC yet. should I create it? i tryed so:
<br />
1> create database newdb<br />
2> go<br />
1> restore database newdb from disk='D:\urban\tmp\newdb.bak'<br />
2> go<br />
Msg 3154, Level 16, State 4, Server I_01\SQLEXPRESS, Line 1<br />
The backup set holds a backup of a database other than the existing 'newdb' database.<br />
Msg 3013, Level 16, State 1, Server I_01\SQLEXPRESS, Line 1<br />
RESTORE DATABASE is terminating abnormally.<br />
1><br />
may be I didn't understand you?
how can I attach that backup file into existing db? thanx!

Hi
Use SQL Enterprise Manager (SQL 2000) to attach database.
Just follow this steps (if you have installed in your machine).
If this is the first time you are opening it. Then you need to register SQL Server. Just right click on the group, Click New SQL Server Registration, do create it using the wizard window.
Once you create it.
Right Click the Database-> All tasks -> Attach Database. And select the backup file. By default 'Attach as' will be your database name, you can change it as your wish.

hm.. I have MS SQL 2005 Express Edition. I think there aren't any GUI tools there.. can I do it from sqlcmd?
and another question - I think SQL Enterprise Manager isn't a free tool? can I download it? should I registred it after that?

I havent got ANY GUI tool so I cant do it. now I download "SQL Server Management Studio Express" but I solved this problem with sqlcmd
1> restore database new_kupimebel<br />
2> from disk='D:\urban\tmp\newdb.bak'<br />
3> with move 'newdb' to "c:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data\newdb.mdf",<br />
4> move 'newdb_log' to "c:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data\newdb.ldf"<br />
5> go
now all is ok.
thanx 2 all

I have execute SQL select max(distinct column_name1) from Table_name where column_name2='XXX'
This query is executed well in Query analyzer.
I tried with different ways.
I used CReceordset class.
In this case i am getting Invalid descriptor index as database exception while using Open(AFX_DB_USE_DEFAULT_TYPE,csQuery)
What way i cab execute this query???

It's possibly not working because no column name is being returned. Try changing the query to:
SELECT MAX(DISTINCT column_name1) AS max_column_name1
FROM Table_name
WHERE column_name2 = 'XXX' Using AS here will ensure that the column is named in the result set.

I have to monitor the database if still processing or not, because I have a script that transfer data from other database to another database, I dont have any idea if the process is finished

Hi,
Im working on a simple message board, where the user has two options when he visit the page, either he post for comment (update) or post new thread (insert).
On my table I have the following fields
MessageID
MessageTitle
MessageText
below is the SP that I made but does'nt seem to do the work, can you advice me on other apporach.
Thanks
Dom
ALTER procedure [dbo].[sp_alterMessage]
(
@messageTitle varchar(50),
@messageText text,
@messageID int output
)
as
begin
if not exists(select messageTitle from Messages where messageTitle= @messageTitle)
begin
insert into
Messages(MessageTitle, MessageText)
values
(@messageTitle, @messageText)
set @messageID = scope_identity()
end
else
begin
update Messages set MessageText = @messageText where MessageID = ltrim(rtrim(@messageID))
end
end
Thanks
Dom;)

I have some comments on your post:
1-What is the question?
2-It's better to replace:
select messageTitle from Messages where messageTitle= @messageTitle
with
select messageTitle from Messages where MessageID= @MessageID
pass it = 0 for new posts
3-don't use sp_ as a prefix for SP names, this will make SQL Server look for them in master database first which is a performance loss.
|
|
|
|

Hi Hesham,
1. This is the error that im getting when I execute the SP which is wierd becuase when you check on the SP that I created, I don't use @message_id as parameter, any ideas?
Msg 201, Level 16, State 4, Procedure sp_altermessage, Line 0
Procedure or Function 'sp_altermessage' expects parameter '@message_id', which was not supplied.
2. if not exists(select messageTitle from Messages where messageTitle= @messageTitle)
I use this to check whether the messagetitle that the user created was already on the database, i cannot use @messageID because this will surely pass the condition, remember messageID is not yet created because im on the process of adding record.
3. noted, thanks for the info.
regards
Dom;)

Hi
I know that you don't pass @message_id, I suggest that you pass it instead of @messageTitle for 2 reasons:
1- performance.
2- titles can duplicate.
In case that you in insert mode , Pass @message_id=0.
Or you can make it an optional parameter like:
Cerate Proc sp_altermessage (@message_id int =0)
thus when you don't pass it, SQL Server will assume it is equal to zero.
I wish this makes it clear
good luck
