Oracle SQL DataModeler and XSD transformation

Hi,
i want to create a Logical Data Model and have a already defined XML schema, how a can i import the XML elements, data types and documentation of each xml element or attribute and then create the Entities, data types and relatioships?
Pedro.

So, in the meantime, the best way to get started is to copy the examples, like the ones in the wiki entry and adapt them to do what you want to do. The places to add your own SQL and your own names are pretty easy to figure out with a little study. There are a few more examples in the Oracle Wiki, and some on the SQL Developer pages on OTN. Many thanks to Sue Harper and Dermot O’Neill. Find their articles at:
http://www.oracle.com/technology/oramag/oracle/07-jul/o47sql.html
http://www.oracle.com/technology/oramag/oracle/07-may/o37sql.html
http://www.oracle.com/technology/obe/hol08/sqldev_srccodexmlext/xmlext_otn.htm
http://wiki.oracle.com/page/SQL+Dev+SDK+Getting+Started
Also, if you want to create an EDITOR style extension, start by creating a User Defined Report and export it as an XML file. There are only a few differences between the two formats, mostly an extra attribute to tell SQL Developer where to hook the editor to the navigator.
Finally - I wrote my own paper on extending SQL Developer: http://www.smdi.com/employee/JohnF/articles/Extending%20SQL%20Developer.zip

Oracle SQL*Net and TNS Protocol

I need to get technical documents on Oracle SQL*Net and TNS Proticol, down to the bit-level definition. I have talked to serveral people in Oracle Documentation, Sales and Tech Support, but no one could give me any clue so far. Any one can help me on this?

SQL*Net is installed by default with SQL*Plus and any of the clients (OEM uses the JDBC OCI driver and some native connectivity).
It is likely that the version of the client you have installed is not one that TOAD can work with or it can't find the client (is the Oracle home/bin directory in the path?)

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,

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

[ask] about oracle sql injection and escalation

Hello,i'm student , i'm studying oracle,now i want to research about oracle sql injection,i had read some tuttorial such as *'Hacking Oracle From Web,Advanced SQL Injection In Oracle Databases,Oracle Hacker HandBook ...'* but when i try to demo on localserver (11.0.1.6) but not run,and this is my demo
-- first,i created table users
create table users (name nvarchar2(50),pass nvarchar2(50))
-- then i created procedure with system user
create or replace procedure system.adduser(u nvarchar2,p nvarchar2)
as
begin
insert into users values(u,p);
end;
-- grant execute privilege to oc user
grant execute on adduser to oc
-- login with user oc and create a procedure
create or replace procedure sqli
as
begin
execute immediate 'grant dba to oc';
end;
-- and then,i run system's procedure
declare
begin
system.adduser('admin','admin'' ; execute immediate ''declare begin sqli() end;');
end;
i hope oracle master help me to i can understand and improving my knowledge
Thanks

The best forum for this is probably Forum Home » Java » SQLJ/JDBC
Presumably you are refering to oracle.sql.TIMESTAMP. While this is intended to (and does) correspond to java.sql.Timestamp it can't be a subclass because it needs to be a subclass of oracle.sql.Datum.

Oracle SQL Developer and Errors (Line Number Incorrect)

First, I wanted to state that Oracle SQL Developer 2 is a standout job.
I wanted to report, though, that when Oracle SQL Developer 2 can't compile a block of code or a simple SQL statement has invalid syntax, it does not have an option to accurately go to the line of code in question. GOING TO the erroneous line of code doesn't need to be a feature, but often times the line no. REPORTED by Oracle SQL Developer is incorrect by 50+ lines.
Is this something I could fix on my end? I have five other developers griping about this.
Thank you!

I don't know if this is the situation you are talking about, but line numbers for errors in SQL in a SQL Worksheet are not line numbers within the statement but rather line numbers in the worksheet. For example, with the following SQL in the worksheet:
select * from dual;
select * from dual;
select * from dual;
select from dual;Running the "select from dual;" statement (as either statement based on cursor position, selected statement or as script), the error is reported on Line 4, Column 7. As I show line numbers (Tools | Preferences | Code Editor | Line Gutter | Show Line Numbers), this makes sense. Without line numbers showing or having the option to go to the error and with more realistic examples with SQL statements scrolling off the page, I can see that the line number in the errors wouldn't be helpful.
I think -K- is talking about the PL/SQL code editors not reporting the correct line number based on the error line not counting the "create or replace" line at the start of a package (and more for triggers).

Oracle.sql.STRUCT and returns from procedures

I need to know how to retrieve information out of a stored procedure. I have a stored procedure that has a IN/OUT parameter that is used to return an array of an oracle TYPE that is set up in the database (it consists of two numbers and a varchar2. So I am returning an array of these types). I need to call this stored procedure from JDBC and retrieve the data out of it. I can setup the outParameter of the statement and also get the Object out of the statement once the procedure is called. But what is returned to me? An array of oracle.sql.STRUCT objects? A single oracle.sql.STRUCT object? A multi-dimensional array of java objects? Or something else?
Thanks
null

as far as I know, the STRUCT is the returned geometry. so you can declare a SDO_GEOMETRY variable and assing the STRUCT directly to this variable.
For example you have a variable 'geo_variable' and assign it the result of a function like this:
geo_variable := SDO_GEOM.SDO_DIFFERENCE(geom1, geom2, tol );
what you see written like this "oracle.sql.STRUCT@6c08b2.." I believe is the stuct @ the memory address 6c08b2..

A silly question about oracle.sql.timestamp and java.sql.timestamp

Hi,
I'm looking at a method that takes objects of type Object and does stuff if the object is really a java.sql.timestamp. If it is not then an error is flagged. In my case it flags an error when an object of type oracle.sql.timestamp is passed to it. Not really entirely comfortable with java (i'm still learning it), here's my stupid question :- why isn't oracle.sql.timestamp a subclass of java.sql.timestamp? Also in various books it indicates that java.sql.timestamp maps to oracle.sql.timestamp. Does that mean you have to physically do the mapping:
i.e.
java.sql.Timestamp t = new Timestamp( new oracle.sql.Timestamp( CURRENTTIMESTAMP ).timestampValue() );
or is there something else to it.
Thanks.
Harold.

2 Weird Errors In Oracle SQL Dev and Toad

I upgraded to vista 32 bit.
Trying to make a connection to ORACLE SQL Developer.
I get the following error:
"An error was encountered performing the requested operation:
Error loading native JDBC driver library
Vendor code 0"
So then I decided to use Toad. In toad I get this:
"ORA-12170:TNS:Connect timeout occurred"
Can anyone help me get these tools back up and running correctly so I can access some remote databases.
Thanks so much,
Jon

When I try sqlplus (which I dont really use) so I hope I am using it correctly.
In command prompt I typeIt seems that you did not provide the TNS connect string when connecting via SQL*Plus to your remote database.
Do this:
sqlplus [ Press Enter]
username: your_user@tns_connect_string
Password: ********What messages do you get?

ORACLE SQL DEVELOPER and SQLPLUS

How can I run the sqlplus command inside of ORACLE SQL DEVELOPER?
Whe I try to run show SGA command , I get "SQLPLUs command skipped"

jung1975,
I have SQL Developer version 1.0.0.14 installed on my PC.
Under the "Tools" menu, there is a "SQL*Plus" item.
However, you need to have access to the "SQL*Plus" executable.
Since my database server is on a different machine (to my PC), that means I need to have Oracle Client also installed on my PC.
Good Luck,
Avi.

Added jTDS as third party DB connector to Oracle SQL Developer and connecti

I have followed the directions for adding a third party db connector to SQL Developer however as soon as I do the connection manager form doesn't come up for both adding a new connection and editing an exisitng one. I have posted here as I am having issues finsing information or getting help through Oracle forums.

Two things:
1 - Confirm you got the jTDS we recommend from here http://www.oracle.com/technetwork/database/migration/omwb-getstarted-093461.html#conf
2 - Confirm you added the entry in the preferences and pointed to the actual JAR file, not just the directory

Oracle SQL Developer and Application Express

Hi all,
I have a SQL Developer 1.5.4.59.40 and have an application developed in Application Express 10G XE with APEX 3.1.2. I have successfully opened my schema which owns an application, but to my surprise there is no node for viewing my application????? How can i view my application?

Hello,
If you go to your parsing scheme in SQL Developer for ex. SCOTT you'll see a node Application Express.
That should list all the applications that have the SCOTT parsing scheme defined in your APEX application.

The client makes the call (e.g. passing the PL/SQL anon block to the server to be parsed and executed).
This is successful. The server returns a zero return code to that client call. This means successful completion of that database call.
The client can now choose to display any message it wants to inform the user of that - from "+hey dude, it worked!+" to "+command completed successfully+" or whatever.
The database does not return a message string in response to that call - only a return code. What the client can do is make another call and request the associated message from the client driver for that return code. In this case, an English language message file (as queried by the driver) will return the message string, "+normal, successful completion+".
