Schema name of compiling entity automatically prepended - DATA CORRUPTION

- Synopsis -
Forms 6i is prepending the schema name of the user who compiled the form when the schema name is unspecified. When a schema name is unspecified, it should use existance and synonym rules associated with the runtime user. Forms new mode of operation is incorrect and may have caused DATA CORRUPTION on our system.
- Main Text -
When creating a .fmx under Dev 6i, the user name of the user who compiled the form gets automatically prepended to database functions, procedures, and tables, which are called in a form function or procedure. But this incorrect implicit user/schema name remains hidden from the Developer.
Forms should not do this, it should, as it used to, allow the database to handle which schema is to be referenced using synonym and existance rules based on the user running the form, not the user who compiled the form.
This is EXTREMELY BAD. I'm a 12 year veteran of Forms, OCP certified, and this has caused potential DATA CORRUPTION in our database. In our database, we have a main and a test schema, both with all of the same schema elements. We found out that there was a problem when data that was being pulled back from a function was being pulled from the other schema, because the FMB was compiled under that other schema's username.
The fact that forms will behave this way is not apparent through the Developer either. The prepended schema name does not show up in the procedure or function call. I had to go in to the .fmx file with a hex editor to determine that forms was doing this "for" me.
If there is some option that tells Forms not to prepend the schema name, please let me know, but I already looked through every entry in Help with the word schema and didn't find anything.
For any whom work at Oracle, this should be fixed immediately and sent out on the next revision of Developer. This has potentially disastrous affects on data. If a fix has already been made please let me know.
Thanks,

Hi John,
Yes, we're running against Oracle7. Well, at least I know how to fix the problem, now I just have to find time to update the database.
Thanks,
Rob

Schema name is not showing in the Data load

Hi All,
I am trying to load a CSV file using oracle apex data load option. The options are using a new table and file upload(.csv). In the load data page, the schema name is not listing my current schema because of which i could not to upload the CSV file.
Can anyone please help on this ?
I am using oracle apex 4.1.1
Regards
Rajendrakumar.P

Raj,
Did you export this application from another workspace perhaps? I have seen in the past that if you create a data load page based on schema A and then import that application and set it to parse as schema B, it will not work.
The solution - although unsupported - is to simply alter the parse-as schema reference in the APEX export file. A more supported version would be to re-create the data load pages in the target application, so that it picks up on the proper parse-as schema.
Thanks,

How can I automatically prepend comment blocks to stored procedures?

How can I automatically prepend comment blocks to stored procedures?
In my organization, the standard is to comment all stored procedures with a comment block that looks like this:

Passing a Schema Name to a Procedure

Hi,
I'm hoping there's a really simple answer to this...
We have an Oracle database containing many schemata, all customer schemata are identical but hold different data pertaining to each customer.
We also have a 'reporting' schema which has select privileges on all the other schemata.
In this reporting schema we have various ref cursor returning procedures, and we use dot notation to reference the required schema - E.g. 'select * from SCHEMA1.Customers'.
What I'd like to do is pass a schema name as a parameter to a procedure so the one procedure could cover all schemata. - E.g. call p_GetCustomers('SchemaNameParameter'). The procedure would then return the customer data for a given schema.
All I've come up with (thus far) is using EXECUTE IMMEDIATE.
E.g. (very simplified)
create or replace procedure p_GetCustomers(pSchema in varchar2) as
vExecuteString varchar2(100);
begin
vExecuteString := 'select * from '|| pSchema ||'.ICustomers';
execute immediate vExecuteString ;
end;
This does the job in extremely simple procedures/functions, but we have some heavy-duty procedures that would make it extremely hard to do the concatenation as they mention the schema all over the place.
What I'd ideally like is something like...
create or replace procedure p_GetCustomers(pSchema in varchar2) as
begin
select * from pSchema.Customers;
end;
But the above won't compile (table or view does not exist...).
I'd be extremely grateful if somebody could advise on this...
Thanking you in advance (and hope!)...

The owner of the procedure needs to have the ALTER SESSION system privilege granted directly to them, but that is all. The SET CURRENT_SCHEMA <name> just defines the namespace to look in, it does not make you that user. The reporting user (presumably the procedure owner) still needs to have SELECT privileges on all of the tables.

How to exclude schema name from exported files (PL SQL Developer)

Dear all,
Just one question: I am using PL SQL Developer. My goal is to export some data (as .sql and .dmp files) from one database and to import them into the another database (both databases have identical structure - test database and production, just different database names and names of schema. In order to make it possible, I need to exclude schema name from generated export file. I believe that it is possible to do it automatically by setting up parameters of PL SQL Developer. How?
Thank you in advance,
Kindest regards,
Dragana

In the meantime, I have found the answer on my previous question:
Actually, the initial idea (how to exclude schema name from exported files) was wrong. No need for any intervention.
Trick is: Schema name can be changed during the import of exported files (PL SQL Developer during import gives possibility: From User (old schema) To User (new schema) .
Hope that this will be useful info for others.

Any Function module or BAPIs are available to get scheme name for the inter

I have internal order no value in table AUFK-AUFNR , and the internal order corresponding Scheme value is available in IMPR-PRNAM . Now I want to inner join both the tables to extract the data , but there is no common field . Is there any Function module or BAPIs are available to get scheme name for the internal orders?

look at DB-VIEW "V_IVP_OR".

Function not found when package name exists with same name as schema name

Hi all, any help would be appreciated :)
I found an issue with pl/sql resolving a functions location when the db has a package name with the same as the db schema name.
My example:
-- arbitrary test function, not in any package
create or replace FUNCTION testFunc
inTest IN VARCHAR2
RETURN VARCHAR2
AS
BEGIN
RETURN 'a';
END;
-- There is a package called "FM" with functions that are not referenced or used in this example and the db schema is "FM".
-- The following PL/SQL fails with the message: "ORA-00904: "FM"."TESTFUNC": invalid identifier"
select cursor (select testFunc('a') from dual) from dual;
-- The following PL/SQL works:
select * from (select testFunc('a') from dual);
As mentioned the function testFunc is NOT in the FM package. This issue does not happen when I remove the FM package. So it seems like there is an issue with cursors calling functions when there exists any package with the same name as the db schema.
Can anyone tell me why this happens and also what I can add to force the function that is not in any package to be referenced (without Oracle trying to look in the FM package)?
DB: Oracle 11.2.0.2
thanks!
Paul

Hi Paul,
In general I would not advice to have schema and objects with the same name.
Here is what documentation is saying here: How Name Resolution Differs in PL/SQL and SQL
PL/SQL uses the same name-resolution rules as SQL when the PL/SQL compiler processes a SQL statement, such as a DML statement. For example, for a name such as HR.JOBS, SQL matches objects in the HR schema first, then packages, types, tables, and views in the current schema.
PL/SQL uses a different order to resolve names in PL/SQL statements such as assignments and subprogram calls. In the case of a name HR.JOBS, PL/SQL searches first for packages, types, tables, and views named HR in the current schema, then for objects in the HR schema.As you can see above when using PL/SQL for your case Oracle searches first for packages, types, tables, and views named FM in the current schema, then for objects in the FM schema.
And because a package FM is found it is raising an error due to the fact that the procedure could not be found in that package.
I hope this clarify.
Regards.

Need to know schema name and table name associated with a column-URGENT

Hi folks,
I need to know the schema name and the table name associated with a column. Though jdbc has the api to getTableName and getSchemaName, some database vendor like oracle does return empty upon call of mentioned methods. I found that oracle driver does not support that
Can any one give me the solution? It is urgent. Or do you suggest any third pary jdbc driver which can provide those?
Thanks
Angelina

Angelina,
Your question has been discussed several times previously in this forum. Search this forum's archives for "getTableName". Oracle JDBC driver does not implement this (because "it is not feasible" -- according to Oracle).
First of all, I would suggest that you could probably change your application's logic so that you would not need this functionality (but I guess that is not feasible either, right :-)
Alternatively, you could try querying the Oracle database data dictionary.
Good Luck,
Avi.

Default schema names in multi-tier landscape

Hi folks,
We have an interesting problem due to having different named default schemas in each of our 3 hana systems. For example lets say these are our default schemas in our development, staging, and production HANA systems;
DEV_SCHEMA
QA_SCHEMA
PROD_SCHEMA
Each of these replicating data from their corresponding SAP source systems.
Now, we have a view that is developed on DEV hana box and uses DEV_SCHEMA. When this view content is imported to QA or PROD we handle easily with schema mapping. All is well and good although we are not really a fan of this different naming and us developers did not choose this naming (self defense plea here for us brilliant developers whom never make such mistakes... PS: HI LARS! - Go Germany!)
Now we are setting up a connection from BW into HANA using system connection and inside this is a parameter called 'db user'. Although it's called db user it's actually looking for a SCHEMA name. If BW DEV is querying from HANA DEV this schema name would be DEV_SCHEMA. However if BW_QA is querying from HANA_QA then the name would need to be QA_SCHEMA but in our BW landscape we are locked in QA and PROD and normally can not and/or do not want to edit objects in non-native systems. Ideally what we need is our default schemas in HANA to have the same exact name throughout the HANA landscape.
All this said, I can see that it would be great to re-name our entire HANA landscape however that would be a HUGE monumental undertaking as all systems would need to be re-replicated again (at least I think).
Just curious if anybody else has named their schemas differently on each tier? What are most people doing? Naming the default schemas the same consistently or are you using schema mapping?
Thanks,
-Patrick

Hi Luke,
I am new to the project and there seems to be no original version. At some point a bunch of the destination field names were changed on the admin console and errors resulted from it both due to mismatched joins and the use of two word field names. I have documentation of the names for the set of tables in the function area but am having trouble with how everything matches up in the bottom half.. I'll keep working on it

Change schema name without doing export and import

Is there a way of changing the name of a database schema without having to create a new user and exportng objects from the old schema into the new schema?
Are there any system tables that can be changed to modify schema name without creating a new schema?

SQL> select user#,name from user$ where user#=55;
USER# NAME
55 HR
SQL> desc hr.employees
Name Null? Type
----------------------------------------- -------- ---------------------------- EMPLOYEE_ID NOT NULL NUMBER(6)
FIRST_NAME VARCHAR2(20)
LAST_NAME NOT NULL VARCHAR2(25)
EMAIL NOT NULL VARCHAR2(25)
PHONE_NUMBER VARCHAR2(20)
HIRE_DATE NOT NULL DATE
JOB_ID NOT NULL VARCHAR2(10)
SALARY NUMBER(8,2)
COMMISSION_PCT NUMBER(2,2)
MANAGER_ID NUMBER(6)
DEPARTMENT_ID NUMBER(4)
SQL> update user$ set name='RH' where user#=55;
1 row updated.
SQL> commit;
Commit complete.
SQL> select user#,name from user$ where user#=55;
USER# NAME
55 RH
SQL> desc rh.employees
ERROR:
ORA-04043: object rh.employees does not exist
SQL> desc hr.employees
Name Null? Type
----------------------------------------- -------- ---------------------------- EMPLOYEE_ID NOT NULL NUMBER(6)
FIRST_NAME VARCHAR2(20)
LAST_NAME NOT NULL VARCHAR2(25)
EMAIL NOT NULL VARCHAR2(25)
PHONE_NUMBER VARCHAR2(20)
HIRE_DATE NOT NULL DATE
JOB_ID NOT NULL VARCHAR2(10)
SALARY NUMBER(8,2)
COMMISSION_PCT NUMBER(2,2)
MANAGER_ID NUMBER(6)
DEPARTMENT_ID NUMBER(4)
conclusion:
changing the name in user$ does not change then schema name

How to know database name and schema name

Hi ,
Once after logging in the database,how is it possible to know the current database and schema which we r using?Is there any system table where we can get the database names and schema names?
please help me out.itz urgent.
Regards,
Sravan

Probably not.
If the database name is the name of the current database, it would be essentially redundant. If the database name is the name of some other database, in order to get the names of all the tables in the specified schema, you could create a database link to the remote system (which assumes you have a login and password to the remote database with appropriate privileges, that the database server's tnsnames.ora file has an entry for the remote database, etc) and query the remote data dictionary tables. Even if you could do that, however, you could not dynamically create triggers on the remote database since DDL over a database link.
In theory, you could also load an appropriate JDBC driver into the database and write a Java stored procedure that would connect to the remote database (again, with an appropriate user name & password, host name, and port number) and issue DDL against that remote database. I have a hard time believing, however, that this would be a particularly beneficial approach. It would be easier just to put the appropriate code into each database that needs triggers generated or to have a separate Java application that generates triggers for a number of different databases.

Transform the schema name with APPLY_DML_HANDELER

END;
All gets compiled good and runs, but dba_apply_errors shows Ora-23416.
Thanks,
Rohit

Hi Rohit,
ORA-23416: table "string"."string" does not contain a primary key constraint
Cause: The master table does not constaint a primary key constraint or the primary key constraint has been disabled.
Action: Create a primary key constraint on the master table or enable the existing constraint.
It is doable. I've done already done that in 9i. Be conscious that that kind of handler is executed for each LCR. So, that's highly paid.
I think there are new features to do it in a better way in 10g but I haven't tried it yet.
I had a bug somewhat similar that I fixed doing the following:
dbms_rule_adm.grant_object_privilege(
privilege => SYS.DBMS_RULE_ADM.EXECUTE_ON_RULE_SET,
object_name => v_ruleset_name,
grantee => v_new_owner
);

Access other schema's table without specify the schema name

Hi, need ur help again,
I would like to access other schema's table without specify the schema name. for example,
select * from hr.jobs;
What priviledges i need if i want to select the data in this way:
select * from jobs;
Thanks!

Public synonyms have their place, but are not generally a good idea as they will cause conflicts with other schemas and applications. Another think that you can do is issue the
ALTER SESSION set CURRENT_SCHEMA = schema;
The CURRENT_SCHEMA (8i and above) parameter changes the current schema of the session to the specified schema. Subsequent nqualified references to schema objects during the session will resolve to objects in the specified schema. The setting persists for the duration of the session or until you issue another ALTER SESSION SET CURRENT_SCHEMA statement. CURRENT_SCHEMA is a session parameter only, not an initialization parameter.
This setting offers a convenient way to perform operations on objects in a schema other than that of the current user without having to qualify the objects with the schema name. This setting changes the current schema, but it does not change the session user or the current user, nor does it give you any additional system or object privileges for the session.
