JDBC ORACLE SQL

in the oracle database, i have a table with 3 fields which are Number, flag and date
NBR(data type NUM) flag (data type char) todaysdate (data type Date)
i want to update the table with system current date using prepared statement.
String sql = "UPDATE TABLE_NAME SET FLAG = 'Y' TODAYSDATE =sysdate WHERE NBRO = ?"
PreparedStatement preStmt = conn.prepareStatement(sql);
preStmt.setInteger(1,input.getInteger("NBR"));
preStmt.executeUpdate();
i am getting the error below.
Cannot convert field NBR of type NUM to integer...
I would appreciate if some one could help me to figure out the problem...
Thanks,

Hi,
The object input that you are using fails to convert NBR to integer it seems.
In the JDBC spec it shows (in the appendix) the recommended conversions from SQL Types to java types.
It's best to check there and see what java type your NBR field maps to. Use that getXXX and setXXX methods instead.
Best,
Guy

Configuring RAC-aware JDBC connection in Oracle SQL Developer?

How can Oracle SQL Developer be configured to properly connect to an [Oracle RAC|http://en.wikipedia.org/wiki/Oracle_RAC] environment, I.E., not just setup to always connect to one of the individual nodes?
[http://programmersjournal.blogspot.com/2008/08/jdbc-connection-string-for-oracle-rac.html] has an example of a classic and the equivalent RAC-aware version of a JDBC connection string. I've already been using a RAC connection string of the same format from within custom Java applications without issue. I thought the same should be configurable in Oracle SQL Developer by setting the "Connection Type" drop-down to "Advanced", then entering the RAC-aware JDBC connection string as the "Custom JDBC URL". However, upon testing the connection, the following error is displayed at the bottom of the dialog:
Status : Failure -Test failed: Io exception: NL Exception was generated
There is no additional information shown on the "Logging Page" view. Using Oracle SQL Developer 1.5.5.
Thanks!

Thanks, Barry. Just F.Y.I., it is working for me now that I upgraded to the 2.1 EA as -K- suggested. I had marked his reply as "Correct", but probably should have left a response indicating my success as well.
Now, if there's anything you could do regarding the [issues around the display performance of CLOBs, etc., in the Query Result view|http://forums.oracle.com/forums/message.jspa?messageID=3906571] , it'd be very appreciated!

Oracle.sql.* with JDBC drivers 8.0.5

the oracle.sql package is not included in my JDBC driver file classes111.zip given for oracle data server version 8.0.5.
I would like to use the oracle STRUCT and ARRAY type for calling PL/SQL stored procedures taking STRUCT objects in arguments.
Are the JDBC drivers 8.1.* compatible with the oracle data server 8.0.5 (if I only use the STRUCT or ARRAY types)? Is it a way for passing ARRAY of VARCHAR2 values to PL/SQL stored procedure with the oracle 8.0.5 JDBC driver?
thanks

Unfortunately, these classes (oracle.sql.STRUCT and oracle.sql.ARRAY) are not compatible to 8.0 database. There is server format changes between 8.1 and 8.0, and JDBC driver only supports the 8.1 format.
Please upgrade your database to 8i.

Accessing MySQL InnoDB tables via JDBC using Oracle SQL Developer

I had posted a problem in the Oracle SQL Developer forum with how that application (v1.1) accesses MySQL InnoDB tables and someone replied that the "[data migration] team created the integration with MySQL", so I am posting here in hopes of learning more about the problem.
Here's a summary:
When I use Oracle SQL Developer to query MySQL InnoDB tables, I need to issue a "commit" before I do each query to ensure that I am getting current results. Otherwise, it appears to be using a snapshot as-of the last commit. Is this a problem with SQL Developer, or a JDBC configuration, or MySQL problem even?
The full details are here:

Error oracle.sql.* and oracle.jdbc.driver.* not found when using oracle as a database

I am using oracle as database and weblogic 4.5. I have copied the classes12.zip file in lib directory of weblogic. I am getting the error that oracle.sql.* and oracle.jdbc.driver.* not found when i am importing these packages in a jsp file. what i need to do to import oracle driver packages?I put it in the classpath also.
Please Advice!
Thanks in advance
AnuPama

Hi Anupama,
First of all I would be surprised if you would not like to use the connection pooling feature of weblogic (in which case you might not be needing the import the classes directly), and would like to open direct connections to your database. Anyways for doing that I would recommend you to check out the readme doc that ships
along with the jdbc oracle (classes12.zip etc). I am giving an excerpt over here:
These are a few simple things that you should do in your JDBC program:
1. Import the necessary JDBC classes in your programs that use JDBC.
For example:
import java.sql.*;
import java.math.*;
2. Register the Oracle driver before before calling other JDBC APIs.
(This is not needed if you are using the JDBC Server-side Internal
Driver because registration is done automatically in the server.)
To register the Oracle driver, make sure the following statement
is executed at least once in your Java session:
DriverManager.registerDriver(
new oracle.jdbc.driver.OracleDriver());
3. Open a connection to the database with the getConnection call.
Different connection URLs should be used for different JDBC
drivers. The following examples demonstrate the different URLs.
For the JDBC OCI8 Driver:
Connection conn = DriverManager.getConnection(
"jdbc:oracle:oci8:@<database>",
"scott", "tiger");
where <database> is either an entry in tnsnames.ora or a SQL*net
name-value pair.
For the JDBC Thin Driver, or Server-side Thin Driver:
Connection conn = DriverManager.getConnection(
"jdbc:oracle:thin:@<database>",
"scott", "tiger");
where <database> is either a string of the form
<host>:<port>:<sid> or a SQL*net name-value pair.
For the JDBC Server-side Internal Driver:
Connection conn = DriverManager.getConnection(
"jdbc:oracle:kprb:");
Note that the trailing ':' character is necessary. When you use
the Server-side Internal Driver, you always connect to the
database you are executing in. You can also do this:
Connection conn
= new oracle.jdbc.driver.OracleDriver().defaultConnection();
Hope this helps,
Thanks,

Obtaining an oracle.sql.STRUCT through a pooled JDBC connection

Hello,
I am using WebLogic Server 10 and and Oracle 10 and I am trying to obtain a vendor-specific oracle.sql.STRUCT from a ResultSet using a pooled connection defined in Weblogic. I need the vendor-specific object, rather than simply the java.sql.Struct implementation, because a third party library requires it.
What gets returned in the ResultSet is a non-exposed WebLogic wrapper object which implements java.sql.Struct, but which cannot be cast to an oracle.sql.STRUCT. I can use reflection on this object to find and call the getVendorObj() method to obtain the oracle.sql.STRUCT, but this solution is not acceptable because this is not a published API and is not guaranteed not to change in future versions.
How can I reliably obtain a vendor-specific implementation of java.sql.Struct through a WebLogic connection pool in WebLogic Server 10?
Thanks for any advice,

Joe,
Thanks again. With your guidance, I have arrived at the following approach, which I'll post for the benefit of others, and which I'd be thankful if you would validate:
1) Import the jar com.bea.core.datasource-1.0.0.0.jar from %BEA_HOME%\modules, which is the only location of the class WLConnection, which is the only class with the getVendorConnection() method you refer to.
2) Get the logical connection from the pooled data source, cast it to a WLConnection, call getVendorConnection() to obtain an OracleConnection (from the ojdbc jar), and use this connection to obtain the required oracle.sql.STRUCT from an OracleResultSet.
3) Be aware of the limitations and follow the guidelines in the document http://e-docs.bea.com/wls/docs81/jdbc/thirdparty.html#1043646 regarding security, error handling, releasing resources (close only the logical connection), etc.
Does this sound like the approach you had in mind?
Thanks again,

Thank you for the information about the connection being closed.
I will look into using this configuration setting.
You say that you can describe a way to get a handle on an unwrapped
pool object using some documented WLS-specific code. Are you referring
here to the getVendorConnection() method?yes.
This method does not help me
get the oracle.sql.STRUCT object, because even the connection returned
by getVendorConnection() returns a wrapped WL java.sql.Struct object
from a call to getObject().I don't believe it. If you are running in WLS, with a local pool,
the getVendorConnection() will give you the Oracle connection,
which will give you an Oracle statement, etc, down to an oracle
STRUCT object. Once you have a direct reference to the oracle connection,
we're not in the picture when it returns something to you.
It would be great if getVendorObj() were
documented and could be counted on in future versions. To use this
method, one would still have to access it via Java reflection, because
the wrapper class and its getVendorObj() method would be exposed in an
API, correct? Could this method be exposed in the API, so that reflection
doesn't need to be used, or it is exposed somewhere that isn't documented?getVendorObj() is not yet exposed or therefore supported for the general
wrapped object, so you would have to start from the connection and
derive all subobjects from it.

but we could also wish Oracle had done so with it's driver objects.
I will assume your code is running in the WebLogic server, because
an external JVM can never access the real driver object, which will
always really be in the WLS JVM. No active JDBC object is serializable.
How can I reliably obtain a vendor-specific implementation of java.sql.Struct
through a WebLogic connection pool in WebLogic Server 10?There is no way to get a handle on an unwrapped pool object without using some
WLS-specific code, though I can describe a way with documented methods,
and/or I can get our documentation altered to say we'll support the
getVendorObj() method. We introspect every vendor object, and for those
implementations that have done the wise thing, projecting any non-standard
methods as an Interface, we are able to also project that Interface so
the vndor example code should work. However, in some poorly-done
cases, such as for some Oracle stuff, there is either no Interface,
or the Oracle code has extensions that take java.sql objects as input,
(at least that's the signature of the method) but two lines into the
method, the Oracle code assumes and casts the java.sql object to a concrete
Oracle object. In these use cases you need the direct unwrapped object.
We provide and document Connection.getVendorConnection(), and intend
getVendorObj() to serve the same for subobjects, but note the dangers
and responsibilities: We rely on our wrappers to implement the security
and thread-safety of our pooling system. Because user code can get
unrestricted access to the actual connection from most JDBC objects,
we can never trust that we have complete control once a vendor object
is exposed. Therefore, by default we will close and replace every JDBC
connection so exposed, as soon as the current thread is finished with
the pool connection. This hurts performance. We also document a pool
config setting that will tell us that you take responsibility for any such
problems, and not to close connections just because they've been exposed.
HTH,
Joe

Creating my Oracle connection works fine ... code as follows:
Context ctxt = getInitialContext();
DataSource dataSource = (DataSource) ctxt.lookup(poolName);
Connection conn = dataSource.getConnection();
OracleConnection oracleConn = (OracleConnection)((WLConnection)conn).getVendorConnection();
I also have reviewed documentation:
http://e-docs.bea.com/wls/docs81/jdbc/thirdparty.html. In section 'Using OracleStruct Extension Methods' it highlights that
java.sql.Struct struct =(weblogic.jdbc.vendor.oracle.OracleStruct)(rs.getObject(2));
None of the documentation actually mentions oracle.sql.STRUCT. For Weblogic to truely provide support for Oracle it needs an easy way of converting to this data type. At present I cannot interact with Oracle APIs until I can create an oracle.sql.STRUCT.

How can I access the oracle/sql server jdbc driver class files from my cust

I have a war file in which I have custom DataSource i.e mypackage.Datasource class. Its basically the need of my application. In this class we connect to datasource and link some of our programming artifacts .
I have deployed the oracle jdbc driver and deploy my application as ear with datasources.xml in the meta inf file. Inspite of that my code fails to load the jdbc driver classes.
Here is the extract of the code :
        Class.forName("oracle.jdbc.OracleDriver").newInstance();
         String url = "jdbc:oracle:thin:@dataserver:1521:orcl";
        Connection conn = DriverManager.getConnection(url, "weblims3", "labware");
        if(conn != null){
          out.println("the connection to the database have been achieved");
        out.println("conn object achived= " + conn);
Class.forname fails in this case. I can see the ojdbc5.jar the driver jar in usr\sap\CE1\J00\j2ee\cluster\bin\ext\ojdbc5 . I even put the ojdbc.jar in web-inf/lib and application lib but does not help at all. Hope I have explained my problem clearly.
I deployed the jdbc driver in the name of ojdbc5 .
I am stuck here. It will be great help if anyone can help me in this. Thanks in advance.

Bent,
You can access the database from your Java portlet, just like from any other Java/JSP environment. Yes, you can use JDBC, as well as BC4J.
The Discussion Forum portlet was built using BC4J, take a look at it's source to see how it was done.
Also, check out Re: BC4J Java portlet anyone?, it contains a lot of useful information too.

Oracle sql developer and access db

Hi All,
I have connection to oracle and Access dbs’ on my oracle sql developer.
When i try to create a database link from oracle db to access db i have to add Host Name.
Connection details to access looks like this :
@jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=C:\ list.mdb;DriverID=22;READONLY=false}
I tried different variants, but it doesn’t work.
Is this possible to create database link to access db, and if yes, what i have to add for a host name and what is the syntaxes for cross table ?
Thank you

Good documentation here... http://www.orafaq.com/node/60

ClassCastException while inserting in oracle.sql.BLOB

Hi,
I have to insert a blob data in to database . I wrote the code . I'm having a ClassCastException problem in the line oracle.sql.BLOB blob = oracle.sql.BLOB.createTemporary(st.getConnection(), false,
oracle.sql.BLOB.DURATION_CALL); while trying to store a BLOB value I'm using Oracle 9i. (JDBC classes12.jar).
if I use the method with a dedicated database connection that specifies the driver as oracle.jdbc.driver.OracleDriver there is no problem .
But when I use JBoss to run , I will get ClassCastException
I imagine that somewhere in the code of this method there is a cast of the underlying connection leading to the ClassCastException when used in conjunction with the jboss datasource. The code to save the BLOB is as follows:
String sql = " update test set code = ? where id = ? ";
             BLOB   newBlob = BLOB.createTemporary(dbcon, false, BLOB.DURATION_CALL);
              newBlob.putBytes(1,data.getBytes());
              stmt = dbcon.prepareStatement(newsql);
             stmt.setBlob(1, newBlob);
             stmt.setInt(2, Studid );
             stmt.executeUpdate();
             stmt.close();Can any one tell me how can I get this code to work with the datasource implementation.
Thanks

I think this could be a problem with the class loader . Take a look at this thread It should solve your problem.

How to specify JDBC Oracle url using deployment tool - Entity Bean

Hello I'am new to EJB.
When creating a entity bean-managed persistence and you need to specify the jdbc url with user name
and password to establish a connection object, how does one specify that in the deployment
tool?
Heres an example of what has in the J2EE tutorial has in AccountEJB to get an connection object
private String dbName = "java:comp/env/jdbc/AccountDB";
private void makeConnection() throws NamingException, SQLException {
InitialContext ic = new InitialContext();
DataSource ds = (DataSource) ic.lookup(dbName);
con = ds.getConnection();
Now if my oracle jdbc url is to be jdbc:oracle:thin:@Abe:1521:dev
ie My host is Abe, port number 1521 and database name of dev and username/password will be system/manager.
what would my dbName be at the top?
Would my JNDI lookup of a DataSource resource "java:comp/env/jdbc/AccountDB" become "java:comp/env/jdbc/dev" for starters?
In the Resource Factories Reference Code I've add a reference of
Coded Name: jdbc/dev
Type: javax.sql.DataSource
Authentication: Container
and down the bottom of the I've put JNDI Name: MyAccount
according to the AccountClient code of:
Context initial = new InitialContext();
Object objref = initial.lookup("MyAccount");
and put User Name of "system" and Password of "manager"
I'am sure in the source code I have to put
Class.forName("oracle.jdbc.driver.OracleDriver")
else you would get that no sutitable driver error, maybe you don't have to if ejb server is smart enough?
What I'am confuse about is where to specify the jdbc url of "jdbc:oracle:thin:@Abe:1521:dev" ??
Know it won't work because of this vital part. Do you have to put that somewhere else in the deployment tool or properties file, or some other tool??
Please help
Thanks

When running the client after successful deployment with jdbc, I'am getting

One thing I don't like about EJB is that everything is transparent which is good! But its much
harder to debug! :( Tried to see if I can figure it out. Hope someone has seen this problem before?
