Is it a must to create .xsd files with VS ?
ok, After you have created that .xsd file , you want to CRUD, if you know how to Query ,Update,Delete i shouldnt be a problem.

Hi,
I may miss the point now, but first you add a dataset to your project using menu Project/Add New Item... Then select DataSet.
After that you should have a visual designer where you:
- add the tables you need (from toolbox or server explorer)
- add the columns for each table
- add the keys
- add the relations
After this you have a full xsd which has implementation for all typical operations for all of the tables and the dataset.

Thanks for the reply. I have to update multiple tables, namely Product and ProductA, just not sure how to do this.
|
|
|
|

I'm afraid that this is not what you're asking, but after you have created the xsd, you should be able to instantiate ProductA and ProductB datatables directly from your code and apply Delete, Insert, Update and Select methods.
If you need more info, could you post a brief info/code about what you have already done and where is the exact problem.

You can't without resetting the seed. If you think about it, say you had 25 records and you deleted records 3, 5 and 10. When you come to insert you are all over the place. Autoincrement/identity columns are meant to just be used. If do not want gaps then you need to implement your own code to do it.

if u have to delete last row from taable then use this query
<br />
declare @rownum as int<br />
set @rownum =(select max(id)-1 from tablename)<br />
dbcc checkident (tablename,reseed,@rownum)
for more ask again.

Here I made a sample test with temporary table.
create table #numbers (value int )<br />
<br />
declare @i as int<br />
set @i = (select min(number) from myTable)<br />
<br />
while @i<(select max(number) from myTable)-1<br />
begin<br />
set @i=@i+1<br />
<br />
insert into #numbers values (@i)<br />
<br />
end<br />
select * from #numbers <br />
drop table #numbers

Your question doesn't give much idea of what you want, so here are some choices:
CREATE FUNCTION GetRange
(
@Lower INTEGER
,
@Upper INTEGER
)
RETURNS @IntegerRange TABLE
(
Member INTEGER
)
AS
BEGIN
WHILE @Lower<=@Upper
BEGIN
INSERT INTO @IntegerRange VALUES (@Lower)
SET @Lower=@Lower+1
END
RETURN
END
SELECT * FROM GetRange ( 12 , 20 )
CREATE FUNCTION GetRangeById
(
@ID INTEGER
)
RETURNS @IntegerRange TABLE
(
Member INTEGER
)
AS
BEGIN
DECLARE @Lower INTEGER
DECLARE @Upper INTEGER
SET @Lower = (SELECT [Lower] FROM Series WHERE ID=@ID)
SET @Upper = (SELECT [Upper] FROM Series WHERE ID=@ID)
WHILE @Lower<=@Upper
BEGIN
INSERT INTO @IntegerRange VALUES (@Lower)
SET @Lower=@Lower+1
END
RETURN
END
SELECT * FROM GetRange ( 100 )
CREATE FUNCTION GetAllRanges
(
)
RETURNS @IntegerRange TABLE
(
ID INTEGER
,
Member INTEGER
)
AS
BEGIN
DECLARE @ID INTEGER
DECLARE @Lower INTEGER
DECLARE @Upper INTEGER
DECLARE SeriesCursor CURSOR FOR SELECT * FROM Series
OPEN SeriesCursor
FETCH NEXT FROM SeriesCursor
INTO @ID , @Lower , @Upper
WHILE @@FETCH_STATUS=0
BEGIN
WHILE @Lower<=@Upper
BEGIN
INSERT INTO @IntegerRange VALUES (@ID , @Lower)
SET @Lower=@Lower+1
END
FETCH NEXT FROM SeriesCursor
INTO @ID , @Lower , @Upper
END
CLOSE SeriesCursor
RETURN
END
SELECT * FROM GetAllRanges()

Here is what my XML document looks like.
<DATAMATRIX>
<FSDATAMATRIX>
<DM_OBJECT_TYPE>ITEM0</DM_OBJECT_TYPE>
<FIELD1>BELGIUM</FIELD1>
<FIELD2>BEVERAGES, NON-ALCOHOLIC</FIELD2>
<FIELD4>NO</FIELD4>
<FIELD5>YES</FIELD5>
</FSDATAMATRIX>
<FSDATAMATRIX>
<DM_OBJECT_TYPE>ITEM0</DM_OBJECT_TYPE>
<FIELD1>BRAZIL</FIELD1>
<FIELD2>CHEESE</FIELD2>
<FIELD4>NO</FIELD4>
<FIELD5>YES</FIELD5>
</FSDATAMATRIX>
</DATAMATRIX>
Using the following code snipet, I got the XMLDOC variable to update, but it will only update the field that previously had a value of "BELGIUM" to the value in my variable, @XMAXPPM.
SET @XMLDOC.modify('
replace value of (/DATAMATRIX/FSDATAMATRIX/FIELD1[.="BELGIUM"]/text())[1]
with sql:variable("@XMAXPPM")
')
How do I write a modify statement that will update FIELD2 to a value only when FIELD1 is "BELGIUM" ?
Thanks,
David

')

I am using odp.net 10gR2.
Is there a way I can monitor the connection pool, like action connection, connection strings or active connections etc. Also, can I know the like how many connection pools will be there per cpu in my server and can I make any of the connection pool as inactive or disable or something like that ?
Thanks in advance.

Hi,
You should be able to monitor connection pool (and also many other things) using Performance Monitor (open from COntrol Panel). ODP installation adds several new counters and groups by default.
Hope this helps,
Mika
