Oracle JDBC thin driver(10g) returns "int/smallint" as JDBC Decimal type

Hi,
I am using Oracle type 4 thin JDBC driver for 10g. In our code we decide
column type by querying the database using database metadata (as code snippet below)
DatabaseMetaData dbmd = Connection.getMetaData() ;
ResultSet rs = dbmd. getColumns() ;
String fieldName = rs.getString("COLUMN_NAME");
short dataType = rs.getShort("DATA_TYPE");
String typeName = rs.getString("TYPE_NAME");
Now, if I have a table with datatype "integer", "smallint" etc,
DATA_TYPE returned from above is "3" , which is in JDBC is defined constant
for "java.sql.Types.Deciaml"
Question is , How do i exactly get DATA_TYPE code for
"integer" or "smallint" and not "Decimal" ?
I have tested with few other databases with above snippet code and they do return actual DATA_TYPE as "integer" or "smallint"
This is with Oracle 10g database and Oracle 10g thin (type4) jdbc driver.
Thanks,
Chirag

user565580,
As has been already stated, Oracle does not have data-types INTEGER or SMALLINT, only NUMBER.
So even though Oracle lets you write INTEGER, it really creates a NUMBER.
(As Joe mentioned.)
Other databases don't have a NUMBER data-type, they have INTEGER, SMALLINT, etc.
Originally, Oracle database only had three data-types:
CHAR
DATE
NUMBER
If you're going to be working with Oracle database, then you need to adapt yourself to its limitations.
So you'll probably need to define NUMBER data-types using scale and precision.
(As Kuassi mentioned.)
Good Luck,
Avi.

Oracle JDBC thin driver 10g exceptions

Can anyone tell me where I can find more resources about exceptions what I should expect if one node in cluster fails.
Let assume that I am using WebLogic server.
Thanks,

We had a major problem in which we tried to roll the
web app over to running against an Oracle database,
and the number of open connections in our pooling
code (that worked fine with the old database) blew up
when lots of users started getting onto the site.
The connections just were not being released, That statement is non-sensical.
By definition the only point of a connection pool is to NOT release connections.
and any JDBC calls starting spitting out exceptions,
and the Oracle 10g thin client driver was saying that
the maximum number of sessions were open (we were in
the hundreds--we have a per-CPU license, so that
shouldn't be an issue).
We're not sure what to test right now. Whether we
use Statements or PreparedStatements, we try to
always close the Statement (which should close the
ResultSet, if there is one) and then in the finally
part of our try-catch-finally, we try to close the
connection. Is that all we need to do? You must always close the result set first.
Then you must always close the statement.
Then you need to return the connection to the pool - explicitly. Usually, these days, that is done by calling the close method. It is certainly possible that your pool uses another method though.
Can you
think of anything we should be looking for?It is possible you have connection pool mis-configured as well.

How does Oracle JDBC thin driver handle numbers via getString?

Hi,
I have a query regarding how numbers are handled by the oracle jdbc thin driver. The issue I am facing is with regards to the decimal separator (. is en_US and , in pt_BR)
e.g. Consider the below code,
Connection conn = DriverManager.getConnection(...);
Statement stmt = conn.createStatement();
ResultSet rset = stmt.executeQuery("select value from test_table1");
while (rset.next())
System.out.println (rset.getString(1));
test_table1 has a single column of sql type 'number' with a single row having value "123.45"
NLS_NUMERIC_CHARACTERS = ".,"
Database version = 10.2.0.2.0
There is a (generic) method to which a ResultSet is passed and it returns a dictionary of key value pairs. All column values from the ResultSet are retrieved using getString method of ResultSet.
My question is whether the jdbc driver formats numbers (based on the locale) before returning it as a string as part of the getString method?
e.g.
java -Duser.language=pt -Duser.region=BR TestJDBC
prints "123.45" and not "124,45"
Is there a reason why getString always retrieves a number column value with '.' as the decimal separator?
To help make things a bit more clear, all the column values retrieved are then converted into an XML (and hence the conversion to string)
At present, the only way I see out of this is to handle numbers differently.
i.e. something similar to,
if (resultsetmetadata.getcolumntype .. = double OR float OR int OR long.. )
NumberFormat.getInstance().format(rset.getDouble(1));
Is there a better way to resolve this issue?
Thanks,
Binoy

Oracle JDBC thin driver question

Does anyone know if there is a JDBC thin driver available for Oracle that supports "HTTP tunneling" of the SQLNET wire protocol?
Such a driver would package the SQL*NET data stream into HTTP or HTTPS packets and connects to a Servlet proxy on the Web host that unpacks the data and forwards the SQL*NET stream to the Oracle RDBMS and returns the response the same way.
This would help me overcome some firewall issues I'm seeing since HTTP/HTTPS ports are usually opened through a firewall. I know Sybase has a JDBC dirver that does this for their TNS protocol and was hoping some company has developed this for Oracle.
Thanks in advance...

The easiest thing to do is download it as an archive with your applet.
Otherwise, you have to have the files on every client machine.
For netscape, put the classes111.jar in the java classes folder typically:
c:\ProgramFiles\Netscape\Communicator\Program\java\classes.
I'd expect that IE would be setup in a similar way.

JDBC Thin-Driver and Oracle Stored Procedure

I've got a Oracle stored procedure which returns a Oracle record.
How can I retrieve the record in java using the JDBC Thin-Driver ?
Record:
TYPE messagerec IS RECORD
(log_level VARCHAR(2), timestamp VARCHAR2(19), text VARCHAR2(200));

Using PL/SQL BOOLEAN, RECORD Types, and TABLE Types:
Oracle SQLJ and JDBC do not support calling arguments or return values of the
PL/SQL BOOLEAN type or RECORD types. Also, when using the Thin driver, they
do not support calling arguments or return values of PL/SQL TABLE types (known
as indexed-by tables). TABLE types are supported for the OCI driver.
Check the following guide,
http://otn.oracle.com/tech/java/sqlj_jdbc/pdf/a96655.pdf

Is JDBC thin driver 10.1.0.3 compatible with ORACLE-10.2.0.2.0 ?

Hi Everyone,
Please let me know whether the JDBC thin driver 10.1.0.3 Driver compatible with the oracle server 10G version 10.2.0.2.0? We are facing some issues with the compatibility.
The Errors we are getting is : StaleConnectionException while we are using the driver from the Websphere.
Please let us know..Very Urgent.
Thanks in Advance,
Samuel.

Hi Legatti,
Thanks for taking time out and replying me.
We dont know the reason why that error is being caused. Because the error is caused on the production we are not able to make any trail and errors. If we are sure that the driver compatibility is causing the error then we can go ahead and download the latest driver. If the latest driver will solve the problem we have to convince the client that the error is caused due to the incompatible driver. So if you have any documents/information supporting that please help.
Thanks
Samuel.

Oracle server side jdbc thin driver throws ORA-01017

We upgraded our database to 11.2.0.1 from 9.2.0.6.

At the time our issue was resolved, the bug was not published. And, I was told, there was no information in metalink about the isue. I am not sure whether they published some thing in the last few weeks.
This is what resolved our issue.
Step 1: alter system set java_jit_enabled=FALSE;
Step 2: Try your test case. If it is the same issue as ours, your test case will be successful. If it succeeds, Go to step 3. If it does not succeed, it is a different issue.
Step 3: alter system set java_jit_enabled=TRUE;
Step 4: Run your test case. If it is the same issue, it is expected to fail. Go to Step 5 in case of failure.
Step 5: Delete all rows from table java$mc$
Step 6: Restart the database
Step 7: Run your test case. It is expected to be successful.

Oracle JDBC Thin-Driver: Connection still valid (db still open)?

Hi,
I've got a problem with my program. The app opens a connection to an Oracle Database usingt the Oracle JDBC Thin.Driver. Everything works just fine but I can't figure out a way how to find out wheter the connection is still valid, e.g. if the database is still open?
connection.isClosed() return always false :(
Any help is appreciated.
Thanks,
Spaulding

Hi oracle_guru,
unfortunately it's not that easy. :(
You can't just check for
if(conn == null)since the connection won't realize when the db shuts down.
Therefore I created a connection-watcher-thread which uses a prepared statement to check every once in while if the connection is still valid.
Nevertheless, thanks for you reply,
Spaulding

Bug in Oracle JDBC thin driver (parameter order)

[ I'd preferably send this to some Oracle support email but I
can't find any on both www.oracle.com and www.technet.com. ]
The following program illustrates bug I found in JDBC Oracle thin
driver.
* Synopsis:
The parameters of prepared statement (I tested SELECT's and
UPDATE's) are bound in the reverse order.
If one do:
PreparedStatement p = connection.prepareStatement(
"SELECT field FROM table WHERE first = ? and second = ?");
and then bind parameter 1 to "a" and parameter to "b":
p.setString(1, "a");
p.setString(2, "b");
then executing p yields the same results as executing
SELECT field FROM table WHERE first = "b" and second = "a"
although it should be equivalent to
SELECT field FROM table WHERE first = "a" and second = "b"
The bug is present only in "thin" Oracle JDBC driver. Changing
driver to "oci8" solves the problem.
* Version and platform info:
I detected the bug using Oracle 8.0.5 server for Linux.
According to $ORACLE_HOME/jdbc/README.doc that is
Oracle JDBC Drivers release 8.0.5.0.0 (Production Release)
* The program below:
The program below illustrates the bug by creating dummy two
column table, inserting the row into it and then selecting
the contents using prepared statement. Those operations
are performed on both good (oci8) and bad (thin) connections,
the results can be compared.
You may need to change SID, listener port and account data
in getConnecton calls.
Sample program output:
$ javac ShowBug.java; java ShowBug
Output for both connections should be the same
--------------- thin Driver ---------------
[ Non parametrized query: ]
aaa
[ The same - parametrized (should give one row): ]
[ The same - with buggy reversed order (should give no answers):
aaa
--------------- oci8 driver ---------------

Jdbc oracle jdbc-thin driver subname

I am working on Windows 2000 environment, using oracle8i 8.1.7 JDBC-Thin driver for use with JDK 1.2.x. The oralce8i 8.1.7 database is on another linux box. I can access the linux box through its ip address, but not by its hostname since it's not accessiable by the dns server. In my code, in the JDBCUrl, I used ip address instead of the hostname, e.g. "jdbc:oracle:thin:@10.0.113.108:1521:ora1". But I got the error like: "java.sql.SQLException: Io exception: The Network Adapter could not establish the connection". If I add a entry in my working machine's hosts file to map the hostname, I can fix the problem. But I don't know if this is the solution, or there is other better solutions.
Thanks
null

Using a hosts file entry is a common solution for problem where the dns lookup does not contain an entry for a RDBMS server platform.
The real solution is to resolve this issue :
"where the dns lookup does not contain an entry for a RDBMS server platform."
