seems like you have locking problems .. do you access the same tables ?
in both connections ?

Yes, when I'm accessing the same table, it hangs, but when I access another table it not hangs, but SQLServer locks a whole table when I insert a single record ?.

Thanks

No..
locking is not this simple..it differs according to how you access the table..
tell me the query so i can help !!

Here is a trace of the steps shown in sqltrace tool:

<br />
with the first connection<br />
exec sp_reset_connection<br />
SET TRANSACTION ISOLATION LEVEL READ COMMITTED;BEGIN TRANSACTION<br />
sp_reset_connection<br />
update objectes set [Caducitat]=NULL, [DataValid]=NULL, [UltimaMod]=CONVERT(DATETIME, '2003-01-16T13:18:00', 126) where id=100225<br />
with the second connection<br />
sp_reset_connection<br />
select * from objectes where idref=''BAINtiA000046'' and IM1=1'	<-------------It hangs here

It's all.

Thanks.

Using Open XML can I join fields in XML document to field in my database via in a stored procedure, perform a check, and return a dataset/XML?

Thanks

Hi developing my WEB application win ASP.NET (C#)

i got this error message in my browser

SELECT permission denied on object 'Contacts', database 'Contacts', owner
'dbo'.

this is the code where it stopped

Line 30: sqlDataAdapter1.Fill(dataSet11);
Line 31: //Update the data grid
Line 32: DataGrid1.DataBind();

Now i finally i grant the access to the database for user ASPNET but it
seems not working yet.

I am running MSDE (Sql Desktop engine)
so i am using osql dos command and scripts to grant the accesses

What i am missing ?????

Thanks

If you are logging into SQL Server with the ASPNET account you need to make sure that the login exists :

sp_helplogins

Verify that the ASPNET user account is created in the Contacts database

sp_helpuser

And that the uid of the ASPNET login is the same uid as the ASPNET user. (logins are to a server, users are to a database)

Then check the permission that the ASPNET user has against the table in question:

sp_helprotect

If you don't have sufficient permission, use the GRANT SELECT ON <object> TO <user>.

Determine column's datatype

Is this possible... to determine the datatype of the column, in ACCESS database... like text/date/memo etc...

If you are using .NET i'm aware that the OleDbDataAdapter has a functio to retrieve the schema of the database.

WebBoxes - Yet another collapsable control, but it relies on a "graphics server" for dynamic pretty rounded corners, cool arrows and unlimited font support.

you could use ADOX which allows you to access an databases data definition language. I have some code which you could use, i'll post when i get into work.

I use the .type to extrract the type of the field in the database. It works fine....

I have a query which returns a recordset for a statement which is displayed in ASP. It works very nicely - except for one thing. I suddenly noticed that although my

if rstDisplay.BOF or rstDisplay.EOF then - display error msg

else - display statement

works really well unless the firm has never had a single transaction (iow. if it has had transactions, just not within the current requested dates). The page then errors. After investigation I have found that it is because of fields sitting in the background which have been returned (eg. the firm name does exist in one of the tables, so that field is hiding in the background somewhere)

so the following returns:

Response.Write "state: " & rstDisplay.State -Displays "1"

Response.Write "count: " & rstDisplay.Fields.count -Displays "18"

so now I want to play with joins in query analyser. I am using @@rowcount to see how many rows are displayed, but don't know what to use to show the fields (like asp .fields.count). Can anyone enlighten me please?

Thanks Smile | :)

Megan,

If you are using Query Analyzer, it should show you the number of rows returned in the lower right hand corner without having to use rowcount. Under the results tab, there should be a boxes that show the following:

General Message, Server Name, User Name, Database, Execution Time, Number of Rows, and Caret Position

Additionally, if you want to see the @@Rowcount Variable in Query Analyzer, you mut declare a variable, set the variable = @@Rowcount and then print the variable.

<br />
DECLARE @myRows Int<br />
Select * from myTable<br />
Set @myRows = @@RowCount<br />
PRINT @myRows<br />

Hope this helps.

Jeremy

Hi,

Thanks - that's exactly the problem. The rowcount returned is 0. But if I click on the messages tab there appears to be an empty row there (I can go up to an empty line with my arrow keys). There is actually no row returned that meets my criteria, but info does exist that does meet some of the criteria, but not all (perhaps I should use a join instead of "and"?) and so the recordset is returned empty.

It's all very odd, but I'm probably just doing something silly.

Thanks again Smile | :)

Megan,

If you can show me your SQL, sample data in the table, and the result you expect, maybe I can help.

Let me know.

Megan,

When you run a query in QA here's what happens.

SQL Server sends back as part of the data stream, a header, data rows and the footer. The header contains the column information as to the number of columns, column names, and data types. The next section in the data stream is the actual row data and the footer contains the rowcount information.

So if you issued a query "SELECT * FROM authors WHERE 1=0" you would get a header with the column descriptions, no row data, and a footer that says "0 rows affected".

So when you are running your query, sql server is building the datastream and returning it to you but due to your join there are not any qualifying records, so you don't see any data.

It sounds like you want to return the firm regardless of whether they have any orders or not. if this is the case then you need to do an outer join between the firm table and the order table so that you guarantee yourself that you always get the firm data, but then all the order data would be null if there aren't any matches.

SELECT f.*, o.*
FROM firm f
LEFT OUTER JOIN order o on (
f.firm_id = o.firm_id
)

But if you post a sample of the query you're trying to run and the results that you want, I'll be better able to give you a solution.

You don't have to post the full query, just enough to get the general principle.

I use access database. I use ASP page to communicate with my access database. Is there any way to find the list of 'tables' in my access database from ASP or using jscript??

Thanks

Sure, using ADODB you can.

Have a look at the MSysObjects[^] table in Access.

It is very similar to the Sysobjects ,et al tables in SQL.
