Does Openrowset Reconnect Everytime?
Apr 18, 2008
Hi,
I'm testing performance of OPENROWSET,
I executed OPENROWSET 3 times in a sequence. But in Profiler i see only following events..
Audit Login
Batch Started
Batch Completed
RPC:Completed.
RPC:Completed.
:
:
:
:
RPC:Completed.
I'm intersted only to see if the login happens three time, but i'm not able to see that. Also, there was no Audit Logout.
Does SQL Server automatically pool connections ?
If i run Openrowset 3 times, shouldn't it open & close connection 3 times ?
Please clarify.
Thanks.
Sandeep.

Hi,
I'm using Oracle 8.1.7 as linked server on SQL Server 2000. Everything works fine. But if is Oracle server is down while executing an query to linked server an errormessage is returned (correct).
When Oracle after that is available and I try to execute the query again the same errormessage is returned again. The only way is to restart the SQL Server.
Is there a better way to reconnect to linked server ???
Thanks.

Hi,
Our environment is:
Windows Server 2003, Service Pack 2
SQL Server Express 2005
SQLServer JDBC driver 1.2
Sun JDK 1.6 (we tried this on JDK 1.5 as well)
There is no virus protection software on the host, and no firewall is enabled.
Our problem is that the JDBC connection running on the localhost periodically gets disconnected, and then we can't reconnect to the database at all, unless we physically power cycle the server. The error message we receive is: "Software caused connect on abort: recv failed"
This is a very strange situation, and to illustrate, I created the following command-line program:
public class DBTest {
public static void main(String[] arg) throws Exception {
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
Connection conn =
DriverManager.getConnection("jdbcqlserver://127.0.0.1:1433;databaseName=datamart",
"username", "password");
System.out.println("Connected");
conn.close();
}
}
Essentially, this program verifies that a database connection can be made to the SQL Server instance on the local host.
Executing this from the command line works the vast majority of the time.
However, once the Web application running on the same host encounters the JDBC disconnection issue, executing this program from the command line results in the following exception:
C:Documents and Settingsfrank>java -cp sqljdbc.jar;. DBTest
Exception in thread "main" com.microsoft.sqlserver.jdbc.SQLServerException: Software caused connect on abort: recv failed

at java.sql.DriverManager.getConnection(Unknown Source)
at java.sql.DriverManager.getConnection(Unknown Source)
at DBTest.main(DBTest.java:7)
There is no way to obtain further access to the database, except by power-cycling the machine. Shutting down and then re-starting the SQL Server instance does not help, nor does restarting any individual process on the server.
Something permanently disables connection to the database server, and only a hard reset of the OS solves that problem.
Any suggestions would be most appreciated, as this is a serious, mission-criticial problem for us right now.
Thanks,

I have an old application to maintain that uses CDatabase to connect to SQL Server. If SQL Server is stopped and restarted, such as in a cluster failover (i.e. move group), then the CDatabase connection needs to reconnect. It seems that it's not capable of doing this on it's own so I need to check the state some how. Various methods, such as IsOpen, seem to be useless as far as determining if I have a "good" connection.
Any thoughts?

I have an ODBC 3.0 Application on Windows NT Server maintaining aconnection to a SQL Server 2000 database on the same machine. When anerror occurs, I'd like to be able to determine whether the error isserious enough that the database connection has been lost, so I canhave the application try to reconnect automatically. My understandingis that any error of severity 20 or above includes a broken connection,but I'm having difficulty retrieving the error severity through ODBC.So my first question is, how do I retrieve the error severity throughODBC?Also, as a test, I stopped the database while my application is stillrunning, and the first error I received had a native error code of 55.There is no 55 error in the sysmessages table, so I'm confused as towhat the severity of the error is. Can anyone shed some light on why Iwould be receiving an error code that is not in the sysmessages table,and where I might be able to find more information about the error?Thanks in advance,Abram

i have the following step in a stored procedure
Alter table ABC
Add constraint Primary_KEY_ABC
PRIMARY KEY (DATE, Amount)
but i get the error primary key already exists.
So is there any way I can generate a unique name everytime I run the
proc, its runs only once a day so can i use getdate() in the name somehow. is it possible.

When I open a report definition, go to a dataset and open it, the CommandType ALWAYS goes to "Text". I don't want "Text", I want "Stored Procedure". I NEED "Stored Procedure".
I have also found that the CommandText for a different dataset will change even though I have not opened it.
I guess the only solution I have is to open the RDL files, search for the dataset entries and then fix the XML code. This is a real pain in the buttocks when I am working with 300+ reports.
Is there a fix for this bug? Or are you going to FORCE everyone to use "Text"?
I am trying to finish this project so that we can release it to our customers but now I have to wonder why we decided to go with Reporting Services, especially now that we have to do double edits on each and every report.

In my SSIS package I have a text file source that I am mapping to a destination table. I have an error component that logs any row level errors and have noticed that it is not logging the correct field. I know this because I have a few different sources that submit the same files and have looked at the source of both. THE ONLY DIFFERENCE in the one that works versus the one that does not is that 2 of the 25+ columns are switched. I would not think this would matter because field A in the text file is mapped to field A in the database.
Does the order in which the fields come into the SSIS package matter?
Thanks

Every time I execute DBCC DBREINDEX (Table_Name, '',0)WITH NO_INFOMSGS the server hangs. No error messages in windows 2000 logs or in the SQL 7.0 logs.
The table is about 2 gig in size and the index is a clustered index on two fields.
The server has 1 gig of memory and the cache hit ratio, and cache flushes both look good. Any ideas? Any help would be greatly appreciated.

Hi All,
I am trying to execute a package (programmatically) that is stored on my local disk using the information that is provided on the following page:
http://msdn2.microsoft.com/en-us/library/ms136090.aspx
This means, I am using the Application object and the Package object to actually load the package using the path to it.
So my code looks something like this:
-----
pkgLocation = @"<package_path>/Package1.dtsx";
app = new Application();
pkg = app.LoadPackage(pkgLocation, null);
pkgResults = pkg.Execute();
Console.WriteLine(pkgResults.ToString());
Console.ReadKey();
---
My package reads in a flat file (located on another server) and transforms it and saves it to a database (on that same server). And mind you, I can execute this package just fine when I do it manually from within BIDS.
But when I try to execute the above mentioned code in my C# solution (compiled to a command line executable), I always get a "Failure".
Can somebody point out what I am doing wrong here?
Thank you in advance,
Manan Pancholi

Hi guys, Im desperately hoping someone here can help me. Ive been trying to set up merge replication between 2 servers all weekend and it keeps failing. Im setting this up as follows
The Publisher/Distributor is a SQL Server 2005 machine, the database being replicated is 4gb, and the only subscriber is a SQL Server 2000 SP4 machine. I set up my publication normally, and set up the push subscription, adn set it to initialize immediately. It weill then start bulk copying and go on for about 3-4 hours before it fails and gives me the errors:
Error messages:

i have an SSIS package that exports to an excel file. This works fine. the problem is that it appends the data instead of overwriting the file. Is there any way to overwrite the file like you can with a flat file? I have to email the file everyweek and don't want to have to clear it out manually. Any help would be appreciated

Hi!
I decided to use OPENROWSET for importing data from an excel file into a sql table.When I import the data,I have a problem:
-not all the data is imported to my sql table
-some values in the sql table are different from the ones in the excel file
For example,a value that in the excel file is:87878787 will be in the SQL table:8.78788e+007.
Can somebody pls tell me what's the problem

Hi Folks,I am trying to load data from a table in MS Access to SQL Server 2000using T-SQL OPENROWSET. When I select data from the remote database (MSAccess) using SQL Query analyzer, the columns do NOT appear in the sameorder as seen in Access directly.For e.g. if Access table has columns Cy, Cx, Cz the output in Queryanalyzer appears as Cx, Cy, Cz. It appears to arrange the fieldsalphabetically. This causes problems when I do a 'insert into select *from' as the field definitions do not agree.Is this a bug or is there a setting in Access/SQL which I am missing?Also, please let me know if there is a workaround for this issue.Thanks in advance!Bhaskar

Hi Anyone I am new member and happy to be here.
I am having trouble exporting the correct data from sql server to an excel spreadsheet using 'OPENROWSET'
The problem is that although the data from my sql table is say :
'a',1,2,3 , the excel spreadsheet sees the data as :
'a','1,'2,'3 ..1,2,3 are of course numbers NOT text, its just that the driver has put a single appostraphy before the number !
I know there is a bug with the ISAM driver but has anyone managed to solve this or has anyone have any alternatives ?
best regards

I'm doing an openrowset query on an excel sheet. (Using SQL Server 2005) Everything works great, except that I have one column that has both numeric and text data in the spreadsheet. The query returns that column as datatype varchar but puts nulls in the rows that have numeric data in the spreadsheet.
Any suggestions?
I run:
select *
from openrowset('microsoft.jet.oledb.4.0',
'Excel 8.0;database=[filepathandname],
'select * from [Sheet1$A4:G5000]')
on spreadsheet data that looks like:
Model_id Model_name
. . .
123 t4556
124 x225
125 455
. . .
and get something like . . . .
Model_id Model_name
. . .
123 t4556
124 x225
125 NULL
