Is there any mechanism to refresh a dataset automatically when the data source ,lets say
a table in SqlServer, is updated, deleted or inserted. No periodic fill or execuete a sql statement please.

Thanks

I don't know when the original data source is updated by other user or
an other aplication.
My project is going to be part of a plant automation system. So the events from the
plant level my arise in very short time duration or too long. It depends on the condition
at that moment. So if I periodically fill my data set, what will be the period?
It is very difficult to gess id advance. Having it too short will bring unnecessary workload
for the system. Or having it too long will cause to miss the some indermediate update in
the data source.

I am not very good on Ado.Net. I need to know ,if possible, can I have my client application
to refresh its dataset (automatically) from the data source when it is updated.

Thanks for reply, anyhow

Why would you want to do this? If you have SQL Server 2005, install the SQL 2005 client tools.

I tried it and, no.. you'll get an error when you connect to sql server 2005 from SQL Server 2000 enterprise manager.

Actually you are not giving the size of varchar so by default it will take varchar(1) and you will not be able to insert the record which is greater than 1 character. You have to do like this:-

Create Table Purchase (Name varchar(50),Amount numeric(10,2))

1 . Gaytri it may possible that racords are not matche
2. Or Pass the Date as 07/25/2007 not 7/25/2007
Old tA.CreateDate = '7/25/2007' i think it is problem
New tA.CreateDate = '07/25/2007'

Data stored in CreatedDate colum is DateTime i.e. the column has both date and Time.

but while retrieving you are using only Date. so Automatically system takes time as "00:00:00"

change you condition to ...
ta.CreateDate BETWEEN '25-Jul-2007' AND '26-Jul-2007'

This is because of format of date is different in your table column field(i.e. CreateDate and you are comparing this date with another format which is mm/dd/yyyy. If you want to do it then you have to convert your format and you will sure get result. Now use this query to get the result.

select tU.UserID,tU.FirstName,tU.LastName,<br />
tU.LastName+''+ tU.FirstName'UserId',<br />
tA.UserID,tA.CreateDate,<br />
tA.UpdateDate<br />
from tAnalyst tA,<br />
tUser tU<br />
where tU.UserID=tA.UserID<br />
and<br />
convert(varchar,tA.CreateDate,101)='07/25/2007'

hi
whenever you are dealing with dates..convert the dates to a common format...
you can use convert function for this.

Hi Kiran,

The code below will insert '15' into ten zeroes and keep it right justified.
You will just need to jiggle things a bit substituting your number for '15'

<br />
select stuff('0000000000',11-len('15'),len('15'),'15')<br />

Or even better

<br />
select stuff(replicate('0',10),11-len(cast(15 as varchar(100))),len(cast(15 as varchar(100))),cast(15 as varchar(100)))<br />

I hope this is of help.

Guy
