General Network Error Randomly But Consistantly

We have a .net 1.1 application that gets this both with MSDE and SSE but more with SSE.

It randomly crashes with this error on laptops where they have SSE or MSDE installed on the local computer. They're being referenced by the machineName\Instance because (Local)\Instance had bugs in the past with network connections disappearing and us getting this error.
Now we're getting this, especially with Intel Wireless Cards on a random but consistant basis.

Under SSE we've had to turn on tcp/ip to make our app run, which tells me that something is preventing it from using shared memory access, which I suspect is that we're not using (Local)\Instance, so I tried switching it, and no dice, same problem.

Is anyone else getting this? It's driving us nuts!!!! (and pissing off customers)Are your laptops running Windows XP SP2? Check the firewall if you have allowed the port for SQL Server|||

With respect to SSE, what I would recommend to try is specifying the named pipe protocol in your connection string by adding "Network Library=dbnmpntw;" to your connection string.

If that connects successfull you should be able to turn off TCP/IP on your SSE.

|||Thanks! I'll try that. The firewall was open (but shouldn't have to be because it's local to local...) so I guess using named pipes (which I think is faster anyhow no?) probably can work around it.

Thanks!

General db queries

Hi

I am currently running the IbuySpy Portal on my lap top using MSDE. Could anyone clarify a few points for me ...

1) If I buy SQL Server 2000 which I aim to do ... will this simply install over my MSDE and leave my portal database intact and run it as per normal?

2) I currently use web matrix to explore my portal database - I notice that in the users table of the portal the field size property for the key UserID field is set to "4" - does this in fact mean that there is only capacity to have 9999 users and then no more can be added? I assume this is correct.

3) About sql scripts - is there some utility within SQL Server that you can point at a database and it will create a .sql install script that will recreate a database - is this what Query Analyser is capable of??

Any clarification welcomed

Regards

Johnnny BHope this helps:

1. I don't believe so. You will have to run the sql scripts from MSDE into SQL Analyzer.

2. Int data type's range is: -2,147,483,48 to 2,147,483,647.

3. Try the SCRIPT method: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/sqldmo/dmoref_m_s_5e2a.aspsql

Fundamental help required with SQL connection

I am writing SQL data apps using VB.NET 2003, MSDE is being used as the
server.

When I create and instance of the server, it has a the format
machinename/instancename

This is fine for the developement machine but how does my code connect to
the server when it is on another machine ? When an instance of MSDE is run
on the target, it will produce...
anotherPCname/instancename

Thanks for any helpThe 'Data Source' keyword in the connection string specifies the SQL Server
instance you want to connect to. A best practice is to store the connection
string externally (e.g. config file) rather than hard-code it in your app so
that you can connect to different servers without changing code. Connection
string examples:

Local default instance:
Data Source=ThisServer;Initial Catalog=MyDatabase;Integrated Security=SSPI

Local named instance:
Data Source=ThisServer\ThisInstance;Initial Catalog=MyDatabase;Integrated
Security=SSPI

Remote default instance:
Data Source=OtherServer;Initial Catalog=MyDatabase;Integrated Security=SSPI

Remote named instance:
Data Source=OtherServer\OtherInstance;Initial Catalog=MyDatabase;Integrated
Security=SSPI

Thanks for the reply.

So, I just need to create a text file with the connection string with say

the local machine ID and database name. The application loads this at boot

and

connects to the named server.

When I deploy the application, I have the client alter the text file by

finding

the machine name and modifying the text to suit ??

I suppose I could use a Try Catch and have try with the local settings and

if it fails

it loads the file in the catch sub (or maybe the string is stored in

registry).

One thing I am also unable to find out is. How does MSDE know where the file

is located on the third party machine ? Should the Initial Catalog =

Path+dasename ?

Thanks

To connect to a different instance/server that is running your database then
the connection string will need to be changed. Quite often this sort of
thing is held in the registry and you configure it on installation.
Alternatively you may want to provide a small application to configure the
settings.

I have tried a hard-coded option of connection and it worked.

ie.

TRY
sqlconnectionstring = ...... originalmachinename......password=..."
CATCH
sqlconnectionstring = ...... newmachinename......password=..."
END TRY

I tried to hook this into a config file but I had trouble(I used the wizard
in VB.NET to make the connection string and edited it but the area the code
was placed did not seem to like me playing with the code adding file open
command etc.

I will try by completely coding the connection in the main form load
routine.
Like this

TRY
Load my original instance for development and test
CATCH
read registry and see if validconnect string exists
if so then try to connect else
prompt user for PC name
save name to registry
try to connect
FINALLY
give up
END TRY

would this approach seem reasonable ?

Now, would someone be able to explain how I can automate the attachment at

Preferably, I would like my VN.NET application install to copy the
unattached database files and attach them to the MSDE server.

I am totally new to the VB.net, only learn this about two weeks. I
used codes from MS to create a file upload class then add function to
store the uploaded filename to a table in SQL server. However I kept
getting the error message about "cannot connect to database" No matter
what format I used. I have tried at least two dozen connection stringe
formats either in Sqlconnection or OleDBConnection. Here is the basic
formats that I used:
strCon = "Data Source =localhost;Password=;User ID=sa;Initial
Catalog=Northwind" for SqlConnection
strCon = "Provider=SQLOLEDB.1;User ID=sa;Password=;Persist Security
Info=True;Initial Catalog=Northwind;Data Source=FAL-L6388" for
OleDbConnection.
I use SQL 7, which was installed by default, i,e only have user ID =
sa, no password, use the default Northwind database. That's all. My
Server is local named FAL-L688.
I have replaced the Data Source with Server= but still give me same
error. I even used an udl to create the OleDB coonnection and put
into my string, still NO. I have exhauseted all alternatives. Does
anyone have clue? Is anyway to debug the trasaction? so i can find out
what went wrong?|||Here is my codes:
Imports System.Data.OleDb

oCmd.CommandType = CommandType.StoredProcedure
oCmd.CommandText = "set_order_attachments"

I'm getting confused, are you connecting to SQL Server or to Oracle?

To go back to your original code, the error message seems like it
would from your own code. That is, I cannot really recall any error
that says "Cannot connect to database". It would help, if you could
get hold of the actual message from the client library. To that end,
it would help if you posted more parts of the code, and also if you
found out on exactly which statement, things go wrong.

Stupid check: you have SQL Server running, haven't you?

In addition to Erlands comments, you may want to move the try block earlier
to catch the connection error. Also check out
http://www.connectionstrings.com/ for the connection string, I think you
should be using Data Source instead of Server. Try using the IP address
instead of the name if necessary.

Function works on SQLServer but not on MSDE

I have spent considerable time trying to debug this one without
success.
I have a database which runs on my client's SQLServer 2000. It
contains a scalar-valued text function which works fine.
Using the same function definition in the same way on MSDE it returns
the wrong result. I am baffled. Is there some incompatibility I
should know about?
The function (simplified) goes like this
ALTER FUNCTION dbo.fnDoseRate
(
@.ID Int,
@.WhichDoseRate Int
)
RETURNS Float
AS
BEGIN
DECLARE @.Dose Float
IF @.WhichDoseRate=1
SELECT @.Dose = 1.2
IF @.WhichDoseRate=2
SELECT @.Dose = 2.3
IF @.WhichDoseRate=3
SELECT @.Dose = 3.4
RETURN @.Dose
END
I call it from a query
SELECT X, Y, dbo.fnDoseRate(1,1), dbo.fnDoseRate(1,2),
dbo.fnDoseRate(2,3) FROM MyTable
and the query delivers the expected results
If I change the query to
SELECT X, Y, SUM(dbo.fnDoseRate(1,1)), SUM(dbo.fnDoseRate(1,2)),
SUM(dbo.fnDoseRate(2,3)) FROM MyTable GROUP BY X, Y
and the first 2 of the SUM fields return the same value (appropriate
only to 1,1). If I change the last call to 1,3 it gives the same wrong
value.
Any ideas?

Good question.
The client controls the remote server so I don't readily know about
that. Is there a way I could interrogate it to find out?
Nor am I sure how to find out the service pack level of my MSDE; I'm a
bit of an amateur in this area! Can you point me in the right
direction?
Looking at SysInfo > Loaded Modules, I see
sqlserver 2000.080.0194.00
Is that the correct place to look? And is that the most recent
version? If not, where should I go to update it?
(I run Microsoft Update regularly but I guess it might not reach MSDE)
