Find the type of all tables in Java, can i do that

Hello all
In my postgres database, I have many tables (>100 tables). I want to check all these tables to see if the first field of these tables are correct type and default value. E.g. I want to check the first field is type "int4" and default value is something like
item_id int4 NULL DEFAULT nextval(item_id_seq'::regclass),
Suppose that I have a list of all tables in this database. I am trying to create a Java program to go through all those tables, get the first fields of these table and check its type and its default value
Can I do it in Java or I can only do it manually ?
Thank you very much for any help

You may find Connection#getMetaData() useful.
Here is it's API documentation: http://java.sun.com/j2se/1.5.0/docs/api/java/sql/Connection.html#getMetaData()

How to find the list of all tables populated

How to find the list of tables populated in the implentation of a particular company. DD02L contains all the tables SAP having. But i want only which are configured for a particular company.
Also how to find the list of reports used by all users in a particular company. TSTC contains all transactions. But i require only reports used by a particular company.

Hi Mohamed
You use Solution Manager to do the comparison for you. There are some nice features that will highlight all your customised coding. Have a look at the SolMan resources on the Support Portal e.g. using SolMan for upgrade comparisons.

Get the names of all tables

First I want to tell you: I'm a amateur concerning Java Programming.
My task is to write a java program - using JCO -, which retrieves the names of all tables (a user can access).
Can anybody help me, please?

Hi Michael,
i can't help you because i don't know anything about JCO!
It's simply funny and i'm happy to see a "known face" here!
Perhaps this will help you:

How to find the list of existing tables in a schema using DB link?

Hi
I know how to find the list of existing tables in a schema using the following query
SQL> select * from tab;
but, how to list the tables using a DB link?
For Example
SQL> select * from tab@dblink_name;
why this doesn't work?
Pl advice me
Thanks
Reddy.

ORA-02019: connection description for remote database not foundHave you used this database link successfully for some other queries?
The error posted seems to indicate that the DB Link is not functional at all. Has it worked for any other type of DML operation or is this the first time you ever tried to use the link?

Try out with the help of this package, which will give out the total bytes, unused bytes, calculate the free bytes from total byes-unused bytes.
dbms_space.unused_space(
upper(oname),upper(tbname),upper('TABLE'),

How to find the deleted data in tables

guys,
how to find the deleted data in tables example: i want to see whether anyone deleted data in MB5B report tables like mbew, etc.,
regards,

Hi,
MBEWH is actually the history table of MBEW. It will record all the changes. As I have told you earlier if you have deleted the record dirctly from the table then it will not come even in the table MBEWH
That means no changes have been made.

Find the names of all open forms from inside a PJC

Hi,
is it possible to find the names of all open forms from inside a PJC (pluggable java bean)?
I have tried the window bean but it retrieves currently open windows and reads the title of each window, but what i need is to find the form name not the window title.
oracle forms version: 10g
Thank you
Edited by: user542352 on Jun 26, 2009 1:07 AM

You don't need to know names of all open forms to close them.
Try to do someting like this :
When you need to close all forms, set some global variable flag and call exit_form
in WHEN-WINDOW-ACTIVATED of each form check your global flag and if set, also exit_form.

Finding the type of the BrokeredMessage body (Windows Azure Service Bus)

Hi all
I was wondering if it is possible to find the type stored in the BrokeredMessage body (payload)? I need the body type prior to calling BrokeredMessage.GetBody<T>().
Kind regards
OS

Instead of using a custom property, another alternate is to use the BrokeredMessage.ContentType property.
According to the documentation, this is recommended way to indicate the type of the content of the message body.
