Problem With Two Consecutive Calls To CallableStatement (jdbc Driver 1.1, SQLServer 2005)

Nov 28, 2006

Hi,

I'm getting an error when I make two calls to a stored procedure (which I didn't use to).

This is an example:

import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;

public class Main {

public Main() {
Connection sproc_con;
try {

sproc_con = getConnection();
CallableStatement sproc_stmt = sproc_con.prepareCall("{call getID(?)}");

for (int i = 0; i < 2; i++) {
int id = getID("Test", sproc_stmt);
System.out.println(id);
}

sproc_stmt.close();
sproc_con.close();

} catch (ClassNotFoundException ex) {
ex.printStackTrace();
} catch (SQLException ex) {
ex.printStackTrace();
}

}

private int getID(String tableName, CallableStatement sproc_stmt) {

ResultSet rs = null;
int ID = 0;

try {

sproc_stmt.setString(1, tableName);
rs = sproc_stmt.executeQuery();
if (rs.next())
ID = rs.getInt(1);

} catch (SQLException sqle) {
sqle.printStackTrace();
System.exit(1);
} finally {
try {
if (rs != null)
rs.close();
} catch (SQLException sqle) {
sqle.printStackTrace();
}

return ID;
}
}

private Connection getConnection() throws ClassNotFoundException, SQLException {

Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
return DriverManager.getConnection("jdbc:sqlserver://myserver:1433;DatabaseName=TestDB", "sa", "");

}

public static void main(String[] args) {
new Main();
}

}

The first call is ok, but the second throws an exception at sproc_stmt.executeQuery(); which says:

com.microsoft.sqlserver.jdbc.SQLServerException: Server failed to resume the transaction, desc: 3600000001.
at com.microsoft.sqlserver.jdbc.SQLServerException.makeFromDatabaseError(Unknown Source)

at javaapplication2.Main.getID(Main.java:53)
at javaapplication2.Main.<init>(Main.java:33)
at javaapplication2.Main.main(Main.java:85)

Am I doing something wrong or is this a bug?

I'm running on Win2003 with SQL Server 2005 Developer edition.

Thanks

JDBC Sample Code Using Named Pipe And SQLServer 2005 Driver?

Nov 22, 2006

Hi,

Does anybody have a working Java code sample that connects to an SQLServer 2005 database on a remote host, via the default named pipe, from a client using the SQLServer 2005 JDBC driver? Could you post it, or a pointer to it?

I've gotten java.sql DriverManager.getConnection() to work fine with TCP/IP connections before. But I'm a newbie with named pipes, and unclear on how the connection string/properties are different. I've tried to piece it together from multiple docs and threads, but haven't found sample code that quite fits my situation. I think a simple working example would best clarify the syntax.

The server is not using SQL Express. Most SQLServer configuration options are defaults; the named pipes protocol is enabled.

Thanks

Sending Table Variable Argument Using MSFT JDBC Driver

Nov 21, 2006

I want to call a stored procedure that has a table variable as its parameter. I am using the MSFT SQL Server 2005 JDBC driver 1.1, however I don't know how to construct a table variable from the Java side to place within a CallableStatement. The CallableStatement interface allows me to set various types of parameters (e.g. Boolean, Byte, Blob, Array, etc.) but I don't see anything for table variable.

Is there a way to do this?

SQLServer Declare New Variable Based On Another Variables Value

Oct 26, 2005

Hi, I'm a complete newbie to SQLServer and t-sql generally. What I want to do is create a new variable in a stored procedure based upon the value of another variable.

eg in the loop below I want to create 10 new variables, called @var0,@var1,@var2 ...@var9

declare @varname nvarchar(10)
declare @i integer

select @i=0

while @i<10
begin
set @varname = cast(('@var'+cast(@i as char)) as nvarchar(10))
set @i=@i+1
end

Does anyone know of a way to do this?

SQLServer 2005 JDBC Driver - Date Rendered Correctly On Local Environment(windows), But Not On Websphere Server (unix)

Dec 6, 2006

Hi,

We are trying to move our application from SQL2005 to SQL2005, we are using 2005 jdbc driver 1.1.

The problem we have is, when a date is retrieved from the database, only the year part got correctly, but the date is automatically set to January 1 of that year. The interesting thing is this problem doesn't occur on local development environment (developer's windows platform), it only happens when we deploy the application to production server (unix).

Does anyone know what is going on, how to fix it?

Thanks.

MS SQL Server 2000 JDBC Driver SetDate() Bug Report

Apr 5, 2004

Hi,

Recently, I found a bug in Microsoft's official SQL Server2000 JDBC driver.
It seemed to lie in the Statement's setDate() method. Maybe they simply assumed
all date are represented in 12-hours format.
The test code is below:

public void testMisc() throws Exception {
Connection conn = TransactionManager.getConnection();
String sql = "select count(salescheck0_.ID) as x0_0_ " +
"from T_CHK_OUT_BILL_TEST salescheck0_ " +
"where (salescheck0_.EX_TIME>?)" +
"and(salescheck0_.EX_TIME<?)";
PreparedStatement stmt = conn.prepareCall(sql);
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date timefrom = sdf.parse("2004-04-02 00:00:00.000");
Date timeto = sdf.parse("2004-04-02 23:00:00.000");

stmt.setDate(1, new java.sql.Date(timefrom.getTime()));
stmt.setDate(2, new java.sql.Date(timeto.getTime()));
// stmt.setString(1, "2004-04-02 00:00:00.000" );
// stmt.setString(2, "2004-04-02 23:59:59.000" );
ResultSet rs = stmt.executeQuery();
if(rs.next()) {
int count = rs.getInt(1);
System.out.println("count = " + count);
}
}

The test data is following:
ID, SO_ID,WH_ID,CLIENT_ID,CODE,OPERATOR,CHK_OUT_TIME, STATUS,CREATE_TIME,DELIVER_TYPE

Given the code and data, the expected output ought to be "count = 19"
But it's "count = 19" instead.
However, if you set date by using alternative method like the commented statements,
you can get the correct result.

Does anybody know if there exists any patch?
Could we expect Mircosoft to fix this bug? If so, where could I submit this bug report?

Regards,
Justin

Using 2005 JDBC Driver To Access SQL Server 2000

Oct 5, 2006

Hi,

I'm using JDBC driver for Server 2005 (version 1.1.1501) to access Server 2000. I have no problems reading my data, but every update returns "Cursor is READ ONLY".

If I use driver for Server 2000 I have no problems. And I have no problems running the same program with 2005 driver against SQL Server Express.

Where should I start debugging?

Transaction Left In Open State On SQLServer 2000 And JDBC

Sep 6, 2007

I have a problem where my connection always has an open transaction as viewed by activity monitor.

I am using the latest MS SQL Server 2005 JDBC driver (1.1) and connecting to SQL Server 2000.

This issue arises only when selectMethod=cursor and autoCommit is set to false. This issue does not exist when I connect to SQL Server 2005.

Has anyone else seen this issue?
How can this issue be resolved?

Thanks

MS JDBC Driver Incompatibility With JDBC 3.0 Specs

Aug 8, 2006

Hi all,

We've just stumbled on a 1.0 version incompatibility with the JDBC specs.

Problem: A table with SMALLINT column. According to JDBC specs version 3.0

(p.B-179) and 4.0 (p.221)), the value should be converted to Integer type.

Unfortunatelly we get a Short object :(

Now, I remember, this case was also affecting old JSQLConnect driver from

DataDirect. Could that problem sneak to new MS driver too?

Please let me know any resolution to this problem if exists.

The issue has not been fixed in CTP 1.1 version. Any ideas if it can be fixed??

Cheers,

Piotr

Weblogic JDBC Driver And SQL

Mar 30, 2004

I appear to have an issue here with WebLogic and SQL Server. The WebLogic server is set up to create a pool of connections (max 15, min 4) to the SQL server. The idea is that connections are "leased" to the application for the duration of a transaction and then returned to the pool at the end of the lease. The pool can grow to up to 15 simultaneous connections -- after that the applications must wait for the next available connection in the pool.

As activity subsides, connections are supposed to be dropped down to the minimum number of 4 connections (which are maintained open continuously).

The problem that I can see from SQL is that there are tens of connections that are open (should not be more than 15, right?) and some of these connections have been held open for several days (going back to the last time we rebooted the server 2 weeks ago). I am told that this is a relatively new phenomenon; new within the last 3 months, anyway. I have tried killing some of these processes manually and now they show up in "Current Activity" as being in a "Killed/Rollback" state.

Does anyone have any experience with JDBC/Weblogic and SQL? Any experiences similar to this?

More information:
SQL Server:
SQL Server 2000 (SP3)
Windows NT (SP6)

WebLogic Server:
Weblogic 6.1
Windows 2000 (SP4)
Weblogic JDBC Driver (6.1)

Any input would be welcome.

Can't Get IntegratedSecurity With JDBC Driver

Oct 7, 2006

Hi;

I used SQLServerDatabaseMetaData (which requires a connection to return this data which seems unnecessary) to get:

name: Microsoft SQL Server 2005 JDBC Driver
version: 1.1.1501.101
Passing a url of: jdbc:sqlserver://localhost:1433;DatabaseName=Northwind;IntegratedSecurity=true

I get the error:
Oct 7, 2006 3:46:09 PM com.microsoft.sqlserver.jdbc.AuthenticationJNI <clinit>
WARNING: Failed to load the sqljdbc_auth.dll
Exception in thread "main" com.microsoft.sqlserver.jdbc.SQLServerException: This driver is not configured for integrated authentication.

I copied over x86sqljdbc_auth.dll and then it worked. I assume this is required with the jar file. This leads to a couple of questions:

What are the files xax86sqljdbc_xa.dll & x64 files for? Are they needed?
The jar file can just travel with my java code. Should the dll do the same or does it need to be in the path and/or the default directory?
Are there any other files needed or just these two?

We are deploying our application with the v1.1 JDBC driver, but are getting a little worried with some of the results of our recent stress tests. I wanted to see if anyone could offer any insight into this problem. Also, do you have any expectation for a release date for the 1.2 driver (not CTP).

Under heavy load with a number of concurrent processes loading to a few tables in our database through batched INSERT statements (called executeBatch against a prepared statement), we see these exceptions coming back from the driver:

com.vectorsgi.tw.services.exception.LoaderException: java.lang.NullPointerException

In a test of 20 "jobs" 2 failed with this error, so its certainly not frequent, but not fleeting either. What is also strange about this is that after the two failures (not immediately back to back but within a few minutes of each other) we got a primary key constraint error:

com.vectorsgi.tw.services.exception.LoaderException: java.sql.BatchUpdateException: com.microsoft.sqlserver.jdbc.SQLServerException: Violation of PRIMARY KEY constraint 'PK__X937_ITEM__0E7B75BC'. Cannot insert duplicate key in object 'X937_ITEM'.

Now- I realize that this is very straight forward, but we are almost certain that our key generation code cannot generate a duplicate key. We have been running it 24x7 for three years at a number of customer sites without ever getting a duplicate (under the open-source jTDS driver). Now that we are trying to move to a better driver that is actively supported, we see these primary key violations every once in a while. Its very hard to consistently replicate, but we have received it from 5 of the past 20 stress tests.

I mainly want insight into the NullPointerException, but if there is any possibility that a driver issue could be contributing to my primary key problem--that would sure make a lot of sense. (I realize its a long shot!)

Thanks,

JDBC Driver Vs ODBC?

Mar 21, 2008

Hi;
I am having problem figuring out if the JDBC Driver for MS SQL Server 2005 is faster or setting up a data source from Administrative tools/Data Sources. I have run several tests and in all tests, the odbc datasource is faster. In that case, why having the trouble of downloading a driver if I am not wrong. I have understood that the native driver is always faster than the odbc bridge.
Thanks in advance

Cannot Find The Driver For JDBC

Jan 30, 2006

Hi all, I am building a program using Java and SQL express and I need the driver in order to connect to the database. I have downloaded I think a version for sql server 2005 but it did not work. Can somebody tell me if such driver exists?

Thank you all
