I think sql2005 RS works with .net 2.0?

i've transfered a sql server database from win2k to winXP. It is working fine with the SQL Query analyzer and the Enterprise Manager. But in the asp.net pages it is displayig the error when i fill the sqldataadapter:
Exception Details: System.Data.SqlClient.SqlException: SQL Server does not exist or access denied.
It was working fine with the win2k. Please help!
Thanks in advance

sometimes you need to add the users to the login/security section of EnterpriseManager.
Hope that helped?
Thanks.

In addition to what VK-Cadec indicated, did you change the name of the SQL server accoridingly? The ASP.NET app could still be looking for the old SQL Server.
Hope this helps.

DB: SQL Server 2005
I am trying to figure out how to check that a value exist before inserting/updating a record in a new table. Simplified Example below:
Product
Product_ID (int)
Product_Name (varchar(25))
Inventory
Inventory_ID (varchar(50))
Inventory_Product_ID (int)
Inventory_PO_Item_ID (int)
Inventory_Status (tinyint)
I need to make sure that the Inventory.Inventory_Product_ID exists in the Product.Product_ID table before the record in the Inventory table is inserted/updated. I could create a stored procedure to do this, but the problem still exist that a record could accidentally be manually added to the table without cheking first. (Plus, I would like to throw an error in the stored procedure if the Inventory_Product_ID does not exist in the Products table.) I read that you can not use Select statements in contraints or rules. Would this be an example of using a trigger. If so, I am not too familiar with triggers and would appreciate some guidance with this problem. Thank you in advance.

Why not use a foreign key on Inventory_Product_ID to Product_ID?

I have a wireless network and sometimes there's a split-second hickup in the connection. The application disconnects and you have to relog in. Is there a way to overcome this with a SQLServer setting that allows the connection to stay up with a glitch in the connection.

Why would you maintain an open sql connection? That is terrible desgin. SQL Connections should be closed as soon they are no longer in use. You should be storing the connection string in a variable somewhere and creating / disposing connections each time you need to access data.

Hi All,
I have a problem combining results of two queries. The queries are fired on the same table with the same select list, only the where condition changes. It would be better if i show what i actually want.
This is my table data for example.
Field1 Field2
AB 1
SD 2
SDFG 3
AS 4
QWE 5
BBG 6
I want an output as
Field1 Field2
AS 4
QWE 5
BBG 6
AB 1
SD 2
That means , if i give the value for Field2 = 3 in the query then the result will not contain record with Field2 = 3 and the result should display the record with Field2 > 3
first and the with Field2 < 3 both sorted in ascending order.
I am using the union operator for combining results, but the results are not as desired. Also i feel that the union clause is not efficient since it takes about 4-6 secs to fetch the records.
Is there any efficient solution for my problem. Please reply soon as i have already spent considerable time on this query and i am running short of time now.
Any help will be appreciable.
Thanks in Advance.

I have a data structure that i am storing a set of data in, that is manipulated, before being applied to the database on calling the Save() function.
The database has a unique field, say 'Name', that is constrained as being unique.
This lead me to notice a potential problem that could affect how Datasets work, and i'd like to avoid it without having to turn off the database constraints. The problem is as follows:
Code
====
Firstly, this code is run, adding two records by name to the dataset, and then saving it to the database.
<br />
obj.Add("AAA")<br />
obj.Add("BBB")<br />
obj.Save()<br />
Database
========
After running this code, the database table will look as follows:
id name
1 AAA
2 BBB
Code
====
Then we run the following code, which loads the table, renames the two records in the dataset using a Tower of Babel kind of name swap, and saves it back to the database.
<br />
obj.Load()<br />
obj["AAA"].Name = "---"<br />
obj["BBB"].Name = "AAA"<br />
obj["---"].Name = "BBB"<br />
obj.Save()<br />
Now, at this point, when it tries to do the save, the application should fall over (Assuming i understand how datasets work)
In effect, we have swapped the two item names, "AAA" and "BBB", so we would like the table to read as follows:
Database
========
id name
1 BBB
2 AAA
However, as only two records exist in the dataset, both flagged as 'Updated', the following queries are generated:
"UPDATE SET name = 'BBB' WHERE (id = 1)"
"UPDATE SET name = 'AAA' WHERE (id = 2)"
At which point, on executing the first query, it would attempt to update the database table to the following state:
Database
========
id name
1 BBB
2 BBB
Whereupon, it would crash, as the unique constraint is broken.
The only possible solution would be if microsoft (in all their wisdom) thought of this, and implemented some kind of update stack, which may also work, as all three updates would be applied in order, and no exceptions would be generated. (But i don't think they do as the update commands are handled by the data adapter and the rows merely have an update type indicator)
Will it work, or will in not?
Cheers guys
Tris

UPDATE BB SET BB_old = (SELECT AA_new FROM AA WHERE AA.AA_old = BB.BB_old)
It would be much easier to help you if you posted your actual table and field names. The above SQL is just weird - but it is clearly what you are trying to do.

The Enterprise Manager will give you this error if you have more than one row that contains the same data in every column.
Solution: add a unique Identity column - and you will not get this error anymore (but, your UPDATE might error out when it attempts to create two rows with the same data in every column), or use the query analyzer to do your updates.

Try using JOIN.
