Test Connection Successful, Yet No Data
May 18, 2007
I run XP Professional on a home machine. I recently installed VB 2003 with MSDE. When I go to the server explorer window, right click to add a connection, the Data Link properties dialog box pops up as it should. I select the name of home server, indicate integrated security, and select a sample database such as model or master from the list. The test connection is successful and clicking OK causes the connection to appear in the Server Explorer window. Yet when I go to open the connection, there is no data. The folders for Tables, Stored Procedures and so forth appear but they are empty. I have another 2000 database that a friend sent me. If I try to indicate in the Data Link propetries dialog box that I would like to attach this database, I get the same symptom. Test connection successful, yet when I create and open this connection, the folders are empty. I am a newbie to ADO .NET and I am not sure where to begin. Can someone help?

Hello,
For the following ADO Connection::Execute() function the "recAffected" is zero, after a successful insertion of data, in SQL Server 2005. In SQL Server Express I am getting the the number of records affected value correctly.
_variant_t recAffected;
connectionObject->Execute(SQL, &recAffected, adCmdText );
The SQL string is
BEGIN
DELETE FROM MyTable WHERE Column_1 IN ('abc', 'def' )
END
BEGIN
INSERT INTO MyTable (Column_1, Column_2, Cloumn_3 )
SELECT 'abc', 'data11', 'data12'
UNION ALL
SELECT 'def', 'data21', 'data22'
END
But see this, for SQL Server 2005 "recAffected" has the correct value of 2 when I have just the insert statement.
INSERT INTO MyTable (Column_1, Column_2, Cloumn_3 )
SELECT 'abc', 'data11', 'data12'
UNION ALL
SELECT 'def', 'data21', 'data22'
For SQL Server 2005 in both cases the table got successfully inserted two rows and the HRESULT of Execute() function returns S_OK.
Does the Execute function has any problem with a statement like the first one (with delete and insert) on a SQL Server 2005 DB?
Why the "recAffected" has a value zero for the first SQL (with delete and insert) on a SQL Server 2005 DB? Do I need to pass any options to Execute() function for a SQL Server 2005 DB?
When connecting to SQL Server Express the "recAffected" has the correct values for any type of SQL statements.
Thank you for your time. Any help greatly appreciated.
Thanks,
Kannan

I keep receiving the error message below when I try to connect to SQL Management Studio
"A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.) (Microsoft SQL Server, Error: 233)"
I have tried all of the suggestions in Google, in the forum, etc with not success.
I have enabled the
Named Pipe protocol/ Shared Memory protocol
SQL Server browser is enables
I even tried changing the SQL Server 2005 Shared Surface Configuration with no success.
I did not have this problem until the day light saving time change. I know this may having nothing to do with it but I need some help pronto.
In the error log I have the following error
Could not connect because the maximum number of '2' user connections has already been reached. The system administrator can use sp_configure to increase the maximum value. The connection has been closed. [CLIENT: <local machine>]
Error: 17809, Severity: 20, State: 1.
Not sure what to do or if the problems are related.
HELP, please!!!

Hi, all here,
Thank you very much for your kind attention.
I am wondering if it is possible to use SSIS to sample data set to training set and test set directly to my data mining models without saving them somewhere as occupying too much space? Really need guidance for that.
Thank you very much in advance for any help.
With best regards,
Yours sincerely,

I have just been able to configure remote connection on SQL 2005. I can also access the AdventureWorks database remotely via ODBC on port 1433. The install directions of a some software instruct me to do telnet <hostname> 1433 to check for connectivity. It doesn't work! I gave my instance the name RM and I also tried telnet <hostname>RM 1433 but again failed.
When I try just telnet <hostname> it works.
Can anyone help?

I have a Data Driven Subscription which runs every day for the previous day. If for any reason the report subscription fails, i would like to get the last time it ran successfully. I know in the subscription table we have lastRunTime, but it will show the recent one which failed but i would like to know when it ran successfully last.Â
Example:
Saturday 5:00 AM - Ran Successfully
Sunday  5:00 AM - Ran Successfully
Monday  5:00 AM - Ran successfully
Tuesday  5:00 AM - Failed
LastRunTime column will have Tuesday 5:00 AM.Â
Is there a way to get Monday 5:00 AM which is the last ran successfully ?? How can i get the history of a subscription?

(Isn't this fun? Type MAPI and SQL into Google and it almost tilts!)
Here is the situation:
1- When SQL Agent starts, it establishes a MAPI session. For some bizarre design reason, it keeps that session open as long as it is running, rather than re-opening the session when it has mail to send. (this can be days, weeks, or months)
2- Frequently, Exchange servers are clustered. When the virtual server moves to a different physical server in the cluster, - or the Exchange server is restarted for whatever reason - the (above) MAPI session of the SQL Agent gets jammed.
3- SQL Agent tries, and fails to send an E-mail saying (for instance) that a database dump has completed (etc.)
4- User posts a question to some forum, asking for help again.
My solution: I created a job to run on a daily basis to restart the SQL Agent, and re-establish the MAPI session. Voila!
The problem: Now we (sometimes) get the message:
[241] Startup error: Unable to initialize error reporting system (reason: The EventLog service has not been started)
This is incorrect - the service was never stopped!
*sigh* No hits in Microsoft or Google - Back to the drawing board.
SO: Can anyone think of a way to *test* the MAPI connection in a job step (without actually sending a message), so that the agent restart job is only executed if the MAPI connection is failing?

I€™m trying to resolve an issue and wonder if anybody has ever run into and possibly had a resolution for.
I wrote a custom conflict resolvers to manage data at the column level. What I needed to do to achieve this was to use a remote query to the mobile subscriber that raised the conflict. I€™m trying to put in a rule that if there are any issues connecting to the subscriber I want to use the default conflict resolver and move forward. Here is my issue, it seems there is no way I can test a connection without getting a critical error that I can€™t seem to trap. Example
I was trying to do
Select * from [linkedserver].[database].[dbo].[incident]
If @@error <> 0
use default conflict resolver
What I did to test this was I changed the linked server authentication to an incorrect password to get the following error that there is no way to trap.
Server: Msg 18456, Level 14, State 1, Line 1
Login failed for user 'sa'.
Does anybody have an idea how to trap this? In SQL 2005 there is a stored procedure
sp_testlinkedserver to handle this but I need this to work in SQL 2000 also, it seems many people have ran into this issue on the web and I tried to get the one where sqldmo is used to test connection but that will not work since I wont always know the password. I would like to just check the @@error value after trying to run a remote query.
Thank you,
Pauly C

Hello,
I have an asp.net application which connects to SQL Server 2005 database.
One out of 15 times (approx) the applicaiton does not make connection to the database and an exception is thrown.
I am not sure how to debug this. Should I write some code which can make connections in a loop to test how much stress the sever can handle?
Kindly suggest some ideas. Thanks.

Hey everyone,
I was had just finished creating the architecture for a test databse using sql express 2005 and have been able to get the browser and sql service started just fine. However, When I try to create an oledbconnection or oledbadapter to the database using the Microsoft SQL Server engines I get the following error: I have tried using a direct path to the database in the server name and the computer's name itself. Everything is on the local machine and I have not started remotely connecting. [DBNETLIB][ConnectionOpen (Connect()).] SQL Server does not exist or access denied. I am using windows authentication and have also specified the direct patht to the database in the attach database file: Thanks for the help.

I am creating my first SSIS package, simple, I read a file, a computation and then write it to an excel.
I am getting the message: "Test connection failed because of an error in initializing provider." The database is NOT remote. My computer is slow though. after about 10 or 15 seconds after clicking the button to test my connection, I get the message and much more. The message asks me if the instance name is correct. I don't know what this would be. This message is on the first task, reading the file (finding the file).
The last sentence of the long message is: "Named pipes provider: Could not open a connection to SQL Server (2).
My question is: Why am I getting this message and what do I need to do to resolve this problem?

Have 6 SQL Server 2012  failover clusters  environments on Windows 2012 R2 standard edition.Have intermittent connectivity issues when using Windows Authentication, with the error "test connection failed because of an error in initializing provider. login timeout expired" . Am checking by using a UDL file and have tried the below.
1) Have made port changes to use static 1433 port.
2) Have enabled shared memory and using Named Pipes and TCP/IP by using cliconfig.
3) Have turned off firewall.
4) Loopback is disabled
5) SQL Browser is running, have changed 'Built in Account setting' Â from 'Local Service' to 'Network Service'. but with no effect.
Still I am getting intermittent connectivity issues.

We are setting up a test lab environment with 100 machines. Â We want one master testing db that gets replicated to each to run scripted application tests nightly. Â
My goal is to minimize the amount of work to move this thing to each of the 100 test machines. Â I am wondering if we need to even have the sql local and invest in a monster db server with 100 copies of the db we restore and each test machine point to their own db on that server, or if I should use db mirroring or something to get the master test db to each of those machines instead.

Now that we have a good programming model in SSIS - the question is whether to write automated unit tests for your packages, and would it generally be a good idea for packages?
Also - if yes to write tests - then where to find more informations regarding How to accomplish that?

hi every one,
i need to test SSIS pacakge which will import data from different database where record count is around 5 millions.
iam planning to test it through c# code as well as manually also.
SSIS source : consist of 7 tables
SSIS destination :consist of 7 tables
Using c# code iam trying to run ssis package through batch file.
i am putting expected rowcount, column count in an excel file and comparing same with destination tables by writing query implementing ADO.Net concept.
am i going right way ,can any one suggest best and productive way to test the ssis package .
what are the other things i need to test it.
do any one can add test cases to it.
S.No
Test Case
1
Verify all the tables have been imported.
2
Verify all the rows in each table have been imported.
3
Verify all the columns specified in source query for each table have been imported
4
Verify all the data has been received without any truncation for each column.
5
Verify the schema at source and destination
6
Verify the time taken /speed for data transfer
7
Fields truncated due to difference in length of the field at destination.

Hi,
I use SQL Server 2005 Dev Edition and am not new to making databases (then again, I've had enough experience and my dad does the same thing).
I am (unfortunately) a university student and for my dissertation I am going to produce a SQL Server database with a strong emphasis on data mining.
Obviously, for the data mining to be useful at all I need to produce loads and loads of test data.
Fair enough, and there are applications which do this, such as EMS Data Gen, but can anyone recommend me any other data gen utilities? EMS Data Gen has poor handling of unique attributes, and as I am doing a car manufacturer this will give me problems when I come to the registration number attribute.
Also, why are utilities for SQL Server (and Oracle at that) so expensive? This makes it out of my reach and makes it difficult to build a truly good database that will net me good marks, and demotivates me. :(
Lastly, please feel free to recommend to me any utilities for SQL Server - such as performance monitors, backup utilities. Anything. But if they are priced utilities, they have to be sensibly priced (<£100), because I cannot yet afford to pay >£1k on such utiltiies.
Thanks

We have a website that accesses our SQL databases. In the past, we used our internal employees to improve our SQL databases. However, we want to outsource the work.
There is a lot of information we would like to keep private from the outsourcing.
Is there a way to efficiently make test data throughout our database without changing our original database?
Is a way to easily update our database to the new changes?
I found this product through Google€¦ EMS Data Generator for SQL Server
http://www.sqlmanager.net/en/products/mssql/datagenerator
Would this program help us make test data?
Thanks in advance

Here is my requirement.
There is a production database which has ever increasing data. For testing purposes though, I would like to build a test database with exactly the same schema but only a subset of data copied from the production database . I'll specify the criteria (something like a where clause in select query) for copying the data from the production database.
Is there a tool that anyone has come across to do this job ?

Could a simple backup of the database, then copy that file to the test system and restore the database from that point work or it there more to it?

Hi,
The test.sql scripts I write to test CLR stored procedures run successfully, but when I want to display the resulting data in the database with a simple "SELECT * from Employee"
I get the result as:
Name Address
---- -------
No rows affected.
(1 row(s) returned)
But not the actual row is displayed whereas I would expect to see something like:
Name Address
---- -------
John Doe
No rows affected.
(1 row(s) returned)
I have another database project where doing the same thing displays the row information but there doesn't seem to be a lot different between the two.
Why no results in first case?
Thanks,

In 2000, BCP seemed the way to go. DTS packages would also work. My question is, in 2005, what is the best choice? I seem to remember that BCP ignored all referential integrity constraints, and applying them afterwords was a royal pain. I'm not a BCP expert by any means. Running this at the command line means using the DOS prompt correct?
What is 2005's answer to this?
