PL/SQL :: How To Find If Column Default Value Is Stored As Metadata
Aug 17, 2012
I'm using Oracle 11g enhanced ADD COLUMN Functionality. Adding new columns with DEFAULT values and NOT NULL constraint no longer requires the default value to be stored in all existing records.
Sometimes we change DB columns from NOT NULL with DEFAULT to NULL with DEFAULT. This operation "materialize" column default. Is there an easy way (Dictionary view) how to find, that COLUMN default value is stored as metadata or is "materialized" ?
Oracle RDBMS version : Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production

There is one DBMSJOB i created schedule to run every day at 22:00 hrs. The jobname is IT_TO_DUM_LOADING and the job type is Stored procedure.
I queried all_source and found stored procedure does not exist in database.
SQL> select text from all_source
2 where type = 'PROCEDURE'
3 and name ='IT_TO_DUM_LOADING';
no rows selected
But i could see the job details in dba_scheduler_jobs view. I cannot use WHERE clause in dba_scheduler_jobs to restrict and find only the job row as i receive time zone error. How it is possible to view the job in dba_scheduler job view whereas i could not find the stored procedure of its in all_source?

For ex:
Proc A

end............
[code]...
This loop goes on and on . I want to find the names of all procedures invoked at run time when main api is executed. Is it possible to find all of them using toad ? Is there any tool for doing this ?

I have a table called cust_file, his table consists of a lot of columns (one of these columns called cus_tax) and have a lot of data,I use oracle 11g, I want to change the default value of the column cus_tax to be equal 1, I wrote
ALTER TABLE cust_file MODIFY(cus_tax DEFAULT 1); table alteredbut
after I inserted new data to test the operation, I found that the new record has a value
= null for the column cus_taxthen
I tested using the following query select
data_default from all_tab_columns where table_name='CUST_FILE' and column_name='CUS_TAX'; no rows selected...
Change the default value of the column cus_tax.

Application Express ver. 4.1
I have created a form. Some of the elements are hidden such as updated_by and update_date. I have provided the default values for these attributes as pl/sql expression in the "default section" (Application->page->edit page item). I am using the Process Row process that is automatically created when a form is created.
The problem is when I click the update button, the updated_by and update_date is passed as null values which throws an error from the database.

I am trying to name a column from data stored in a row (Phone number) I want to name it from the first 3 digits (Area code) and I have no clue how to do it I have googled but I think the query is a little too complicated for me to explain it and get a result from google or find it in a section of a book.
My phone numbers are strings, so I initially look for the first 3 characters and then start separating and counting, I can do that, the only problem I have is naming the column WITH the the first three digits that I just separated.

I am trying to name a column from data stored in a row (Phone number) I want to name it from the first 3 digits (Area code) and I have no clue how to do it I have Googled but I think the query is a little too complicated for me to explain it and get a result from Google or find it in a section of a book.
My phone numbers are strings, so I initially look for the first 3 characters and then start separating and counting, I can do that, the only problem I have is naming the column WITH the the first three digits that I just separated.
I am trying to learn by myself how to use databases and am using the HR database that comes in oracle since I read in a forum that it is a great way to learn how to use queries.
I read about using Pivot to do it, but in pivot I need to know how many area codes there are. I will post a screen shot of the table that I am working on the other post
[URL].....
I can group by phone number with this:
SELECT SUBSTR(PHONE_NUMBER, 1, 3) AREA, COUNT(SUBSTR(PHONE_NUMBER, 1, 3)) TOTAL_COUNT
FROM EMPLOYEES
GROUP BY SUBSTR(PHONE_NUMBER, 1, 3);
But what I am interested in doing is that instead of Area appearing as a column, that the actual first 3 digits would appear as the column name.
This is kind of what I am trying to do, but instead of AREA appearing as column name I would like for each one of the area codes to appear as column name, here is the
SELECT DE.DEPARTMENT_NAME, EM.SEX, SUBSTR(EM.PHONE_NUMBER, 1, 3) AREA, COUNT(SUBSTR(EM.PHONE_NUMBER, 1, 3)) TOTAL_COUNT FROM EMPLOYEES EM, DEPARTMENTS DE WHERE DE.DEPARTMENT_ID = EM.DEPARTMENT_ID GROUP BY DEPARTMENT_NAME, EM.SEX, SUBSTR(PHONE_NUMBER, 1, 3) ORDER BY DEPARTMENT_NAME;

Oracle database version is : 10G.
When we try to query a column from a table the output is shown as "?????". Seems the data in that column is stored in a different character set, which is not recognised while displaying the output. The column size is 35byte.
The nls parameter table shows the character set as "we8mswin1252".
get this issue resolved.

I have a table named PRODUCT (ID Number , ProductImage BLOB). I have inserted some records in. I want to create a form for user to view this table.
When I create Data Block, in Data Block Wizard, if I select option 'Table or View' to retrieve data, it's ok (Data type of item ProductImage is Image, when I run form and query, it display image normally).BUT, I want to retrieve data from stored procedure in a package. This is my package
PACKAGE my_pkg IS
TYPE my_rec IS RECORD
(
myID PRODUCT.ID%TYPE,
myImage PRODUCT.ProductImage%TYPE
);
[code].....
I select option 'Stored Procedure' in Data Block Wizard, then select my stored procedure (my_pkg.Do_Query). Next I choose 2 columns from my stored procedure (ID, ProductImage). The wizard still applys data type of ProductImage as Image. I finish Data Block Wizard and Layout Wizard... run form, query and an error message display:
FRM-40364: The data type of item 'ProductImage' does not match the corresponding column in the stored procedure.
I try to change 'myImage PRODUCT.ProductImage%TYPE' -> 'myImage BLOB' in my package but still get that error.

I am having to pull out all the dependencies for a column as below.
When I select a column in a table, it should list
1. All Views that use this column and table
2. All Stored procs that use this column and table
3. All Functions that use this column and table
4. All Pl/SQL scripts that use this column and table.
Is there a easy way of getting this information from the Oracle dba tables?

I have to build something like an export-interface-mappingtool. So user defines more or less a query and I have to display the attributes of this query to enable a mapping.
If I build up a ref cursor fom this query, I did not find the possibility to read its metadata (mostly Type/length is enough).
What I do not want to do is creating a temp. table or parse the query string to derive it from the dictionary.
Is it possible at all to get the metadata of a dynamic SQL ?
