A DateTime value is stored in no particular format, a format is only applied when the value is displayed.

Im returning an XML from a stored procedure using "FOR XML, XMLDATA". Is there any way to specify the name space to be returned? I want to return eg (xmlns="http://App.myapp") and not the default(xmlns="x-schema:#Schema1")
Thanks

Hello!
The uniqueidentifier produces an automated value and it is not acting likely PK in Access database. Therefore I decided to create a uniqueidentifier function which produces a unique value. I defined the first column as an uniqueidentifier column in my table and assigned char(30) instead of uniqueidentifier newID() where I assign produced value.
My question is: is it still mandatory to define this column as uniqueidentifier NEWID() column and then later on assign the produced value to this column as shown example below or can I simply define a column which will be used as an uniqueidentifier column with a definition of Char(30) and then I assign the produces value to this column ?
What would be the prons and cons?
Regards,
<br />
<br />
DECLARE @GUID uniqueidentifier<br />
SET @GUID=NEWID()<br />
INSERT Item VALUES(@GUID,ProducedIdentifier)<br />
<br />
<br />
What a curious mind needs to discover knowledge is noting else than a pin-hole.

I'm not sure I follow you.
To use a Guid, use the uniqueidentifier datatype.
To have it created automatically, set RowGuid to Yes.
To create the Guid separately, set RowGuid to No.
If you don't want to use Guid, don't use the uniqueidentifier datatype.
Don't use character data as a primary key (or at least very rarely).
What problem are you having?

Whenever I run a particular test, i don't get all of the data. But when I run the test in debug, I get all of the data. The test is independent of other tests. The only thing in common is that they all talk to the database (ms access database). Also, I get all of the data when I run all of the tests. Any idea on why this is happening and how I can resolve this problem?
Thank you,
Prateek

After the data gets added to the database, I read and print out the data in nUnit's console from the database. There are times when I can't read all of the data from the table. e.g. if the table has 5 rows, it will sometimes show me only 2 rows. And then there are times, when it would print out incorrect values from the data e.g. if a column has an integer value of '2', it will print out '0'. My guess for this would be that it wasn't able to read the data from that particular column.
What other type of information would you like to know?

I need to know the ID of a last inserted record. The problems is, that I use VS generated dataset and table adapter, so the classic "SELECT @@IDENTITY" is not working.
I also tried to use "SELECT IDENT_CURRENT('tablename')", but for some reasons it crashes at the runtime, saying that function IDENT_CURRENT is not recognized, or something like this.

This query select top 1 id from tablename order by id desc will not be choice for you?

yeah, it worked. Thank you very much. Still, I have a question: isn't it the same as choosing the maximum ID?

No problem.
If ID value is increase-able always then we can use max function to get maximum value of ID.
example: select max(id) from tablename

This only works in a single user environment - otherwise someone else could insert before you run the select. Also, this relies on id being the prmary key, otherwise you should select the max(id) - bad practice to rely on any ordering unless specified.
Do't know what the answer is though, I nvere use tableadaptors etc, there isn't enough control over transactions etc for the sort of systems I usually work on.

select max(id) from mytable should be enought but...you may need to use a lock. Read about it i don´t know much about it!
If it´s a read/report procedure (you don´t delete or edit anything) there´s no problem using select max(id )from mytable, otherwise you must use somekind of lock!!!
To prevent users to edit same thing same time

Try to optimize your query.

Have you considered putting an index on this column (you need to consider that while it may speed up your query, it might also slow down your inserts).
|
|
|
|
|
Besides optimizing your query (perhaps by indexing the column) you can increase the query timeout in your code.
