Sql.exception using jdbc:odbc Sqlserver 7

hi
i use java jdk 1.3 and sqlserver 7.0 on windows98 and establish a connection over jbc:odbc. I use executeUpdate() statement and insert something to a table. there is a trigger defined and sometimes i got an sql.exception, that no rowcount returned.
can you help me ?
thanks jens

The trigger does a rollback in some cases.
Obviously - try this out! - this causes that JDBC exception then.
Now I see a problem in this, that the trigger does rollbacks concering the connection, but your Java program does not know that its connection's actual transaction has been rolled back. Imagine, if you have done several steps before without commitng yet, they are rolled back as well.
So I would use this only with AutoCommit set to true.
I think it's not a good idea in general to let a trigger do a rollback. But in this area I have few experiences.
I assume you have to use this table schema and its trigger definition and can't change it.
So I would find out the error code which this DBException contains.
So in case of exceptions you can identify if this case has happened and react on it in your logic. You must interpretate this as an error or maybe as an expected condition - that depends on your logic.
Another thought: can't you validate the values before you do the insert. Then this logic would not longer be encapsulated in the trigger, but maybe it is really a validation rule which the program should know anyway. What do you tell the user if it has occured?

Yes, you can do that. For testing purposes you can also create simple files (with mkfile) and add these to ASM. That way you could also experiment with deleting files and see what happens in ASM

Null Pointer Exception using JDBC-ODBC bridge on Linux

Wonder if anyone can help me with this one?
I am attempting to use the JDBC-ODBC bridge on Fedora with J2SDK 1.4.2_04, however I am getting a NullPointerException whenever I get the connection. I can get the JDBC connection to work but it is a requirement that ODBC be used.
The code is as simple as it can get.
import java.sql.*;
public class TestClass
   public static void doConnection()
      try
           Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
           Connection cn = DriverManager.getConnection("jdbc:odbc:DB");
      catch (Exception e)
           e.printStackTrace();
   public static void main(String[] args)
      doConnection();
}Running this program using java -verbose TestClass I get the following output.

The UnsatisfiedLinkError suggests to me that a library cannot be found, but I don't know what library.
As far as I know I have configured ODBC correctly. I can achieve connectivity to my database using other tools and I still get this same error irrespective of whether the DSN is valid or not.
I have installed the unixODBC rpm.
Any help/insite would be greatly appreciated.

Database package for handling SQL queries using JDBC/ODBC bridge

I perform a package using J2ME which can stores the contact.It consisting of the fascilities of the editing,Inserting, Deleting,Updating records
i have write import statements as
import javax.microedition.midlet*;
import javax.microedition.lcdui.*;
but when i write import java.sql.* error message shown AS this package does not exist.
So for J2ME using J2ME wireless toolkit 2.5 cldc which package i want to import to implement the sql statements i implement the Database using the text Files.
Requirement is that all SQL statements are implemented.also Which other equivalent packages are there for handling the databases in J2ME.
Please tell me all the package & Answer of the above problem.

Hey
I was told that I can (through Java code) read all the registered DSNs and that way basically modify my application to populate it with a list of databases in the system and then when the user clicks on a database, the program would function as before...i.e. read the list of tables with it..yadda yadda yadda
Can anyone guide me on how to do that? read a list of DSNs in the system etc

Problem using Jdbc-Odbc Bridge

Hi,
I am using Java 2 SDK and I am trying to access MS Access database on my machine using Jdbc-Odbc bridge. I have set up the DSN in ODBC. But I get the following error when I run my program -
'No Suitable Driver'
Here's my code snippet-
Class.forName ("sun.jdbc.odbc.JdbcOdbcDriver");
String dsn = "jdbc:odbc:DriverInfoDB";
Connection con = DriverManager.getConnection(dsn,"","");
con.setAutoCommit(false);
Statement stmt;
String query = null; // SQL select string
ResultSet rs; // SQL query results
stmt = con.createStatement();
.....etc etc...
Where is the error in this code??
Help Needed!!
Thanks
Vivek.

try
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con = DriverManager.getConnection(dsn,"guest","guest");
OR DriverManager.getConnection(dsn);
System.out.println("Conection's opened");
catch(ClassNotFoundException cnfe)
System.err.println(cnfe);
catch(SQLException sqle)
System.err.println(sqle);
try that code and double check you DSN Name . it's a good practice to greate a system DSN.
i hope that helps.

JSP connected to MS Access using JDBC-ODBC

If I want to run a jsp file connected to a MS Access database using jdbc-odbc bridge.
I thought that I should use the following code to make the connection:
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
String database = "jdbc:odbc:Driver={Microsoft Access Driver(*.mdb)}; DBQ=http://myComputerName:8080/examples/jsp/DatabaseTest/mydatabase.mdb;DriverID=22;READONLY=fals";
sqlca = DriverManager.getConnection(database, "dba","sql");
but Tomcat 4.1 produces many errors.
The file runs fine when I determine the complete path and include the local drive (C://) of the database Like the following:
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
String database = "jdbc:odbc:Driver={Microsoft Access Driver(*.mdb)};
DBQ=C:/Tomcat4.1/webapps/examples/jsp/DatabaseTest/mydatabase.mdb;DriverID=22;READONLY=fals";
sqlca = DriverManager.getConnection(database, "dba","sql");
Of course I do not want to use the second code because I want to use my computer as a host.
I will appreciate any answer!

Yes, using the DSN, it works fine.
But, I think it will run from the drive C.
I want to use my computer as a host. So, I think that I should include the name of the computer in the path.
I do not know may I am confused.
I appreciate your reply. Thanks!

To run a report from command line, when using jdbc-odbc bridge

Hi,
How to run a report from command line, when using jdbc-odbc bridge?
Usually with tns, we do by "rwrun module=<> userid=<user>/<passwd>@tns".
with odbc, we do by "rwrun module=<> userid=<user>/<passwd>@odbc:DSN"
Please specify, what is command line arguments for jdbc-odbc bridge driver?
Environment : Oracle 9i Report Builder on WinNT
Database : Sybase
Regards,
Ramanan

Hello Ramanan,
Report Builder : connect JDBC Query in Report Builder is to through Connection Dialog in JDBC Query Editor. User can use a Sign on parameter (can use, default : P_JDBCPDS or can create new) to connect to JDBC Data Source. Connection once made will be mentioned and will be reused through out Reports Builder.
JDBC PDS allows user to connect one or more same or different kind of databases.
While running report through runtime or Server, user can pass the sign on parameter(connection string) value, like any other user parameter.
Syntax for connection string : <username>/<password>@databaseURL . The syntax of database part of connection string depend on the type of JDBC Driver used to connect to Data Source while designing the JDBC Query. databaseURL refer to the location of the database and its format depend on the JDBCPDS river selected in design time while creating the JDBC Query.
rwrun eg :
rwrun report=jdbc_odbc.rdf destype=file desname=output.html desformat=html P_JDBCPDS=scott/tiger@database
Server eg :
http://server.com:8888/servlet/RWServlet?server=MyReportServer+report=jdbc_odbc.rdf+destype=cache+desformat=html+P_JDBCPDS=scott/tiger@database

How to run Excel Macros using JDBC-ODBC

Hi,
I want to run the excel macros in the excel file, after I connected to excel file, using JDBC-ODBC bridge.
How macros treated here?
Help needed please..........
- Ramesh

How to run Excel Macros using JDBC-ODBCYou don't.
As my fuzzy understanding goes.....
Macros (excel, word, etc) run via a "OLE" extension of the script host system.
So the only way to run them is via the OLE interface. That has nothing to do with ODBC. You can write your own JNI to do that, or you might get lucky and find that someone else has written a java library to do it for you.

Java Web Analyzer security hole in SQL Query Spreadsheet using JDBC-ODBC bridge

Hi, I use Hyperion Analyzer 7.0.1 on Windows 2003 and relation database DB2 v8.2. I did: 1. log in to Java Web Analyzer 2. button New 3. Select Layout: Custom Report 4. from toolbar pull down to desktop "SQL Spreadsheet" option 5. "Enter SQL Query" window opens, from JDBC Driver drop down window select "JDBC-ODBC Bridge" 6. in "JDBC Connection String" window replace "db1" string with database name 7. leave JDBC Username and JDBC Password empty (this is default) 8. click on "Test Connection" button. 9. "Test Connection" window opens with message "Connection Succeded"!!! So connection to database without password succeeded. 10. in "SQL Query window" write any SQL you wish and Database will execute the SQL. Conclusion: Connecting Analyzer with SQL Spreadsheet option to relation database DB2 is possible without password. Question: Is there any way to prevent users from executing "SQL Spreedsheet" option? Thanks, Grofaty
