Schema name in front of trigger name.
I have a doubt that all the triggers in my schema of the database of my application of about 200 users have the schema name before the trigger name. Say, if the trigger is 'Trig_1' & the schema is 'Schema_1', then the trigger name is like 'Schema_1.Trig_1'. But, today, i modified one trigger & created it without the schema extension like, say 'Trig_1' as per my eg. I hope, this does not create any problem.
I hope, my question is clear. Please help in solving the doubt as it is urgent.
Regards.
Please help in solving the doubt as it is urgent.This is a simple enough problem to test. If it's that urgent you would be better off investigating it yourself rather than waiting for a passing guru to pontificate. But as I happen to be in the area... ;)
Prefixing the object name with the schema name is a common enough practice in DDL scripts. When the schema name is omitted the object is created in the schema of the user running the command. If the schema name is included, the object is created in the schema specified. When this is the same as the user running the statement there is no difference. However, specifying the schema name does allow us to run installation scripts as power users i.e. those with privileges like CREATE ANY TABLE, CREATE ANY TRIGGER.
Why would we want to do this? Well, if we want to roll out a change to every schema it's a lot easier to log on as the power user account and run one script which installs a trigger in two hundred schemas than it is to log on as two hundred different accounts and run two hundred scripts.
Whether this reflects your situation is a question only you can answer. How is your application installed? If it's run from a single master script you need to include the schema owner in the DDL.
I hope my answer is clear.

How to get the current schema name
Hi,
Can anybody please tell me how to get the current schema name, there is some inbuilt function for this,but i am not getting that. Please help me.
Thanks
Jogeshok folks, I found the answer at Tom's as usual.
http://asktom.oracle.com/tkyte/who_called_me/index.html
I rewrote it into a function for kicks. just pass the results of DBMS_UTILITY.FORMAT_CALL_STACK to this function and you will get back the owner of the code making the call as well some extra goodies like the name of the code and the type of code depending on the parameter. This ignores the AUTHID CURRENT_USER issues which muddles the schemaid. Quick question, does the average user always have access to DBMS_UTILITY.FORMAT_CALL_STACK or does this get locked down on some systems?

Schema name required in scripts
The oracle instance we are running requires the schema name in front of all db objects when running scripts. If I am logged into this schema, I shouldn't need to include it in the scripts. Can someone tell me how to disable this requirement?
Or by setting CURRENT_SCHEMA as well.

Selection from Another schema by default without schema name qualifier.
Hi
Oracle10g release 2, LinuxOS
i want my schema (User_1) to always select,insert, update, delete the objects from another schema (User_2) without passing full schema qualifier every time whenever i don't pass any schema name explicitly.
i.e. if i pass the following guerry
select * from table_a;
the table of user User_2.table_a (User_2.table_a) will be queried by default instead of table (User_1.table_a)
and the same implementation is also required in Functions , procedures, sequences etc.
WishesThree relatively easy options
1) Create private synonyms in User_1's schema for each object in User_2's schema, i.e.
CREATE SYNONYM table_a
FOR user_2.table_a2) Create public synonyms for each object in User_2's schema. This will make it possible for all users to query user_2's objects without specifying the schema name
CREATE PUBLIC SYNONYM table_a
FOR user_2.table_a3) Change the current schema for the session (potentially in a login trigger)
ALTER SESSION SET current_schema = USER_2There are other options that are a bit more complicated like using enterprise users with shared schemas. But most people are perfectly happy with one of these three.

How to configure the schema name dynamically based on user input.
configure the schema name dynamically based on user input.
For ex:
We have two schemas:
Schema1 - base schema having 15 tables.
Schema2 - tables which is specific to modules. Having only 10 tables which is also available in Schema1
Login to application using Schema 1
Access a particlular module and select the country. Here country selection is identified.
Based on the country selection, we need to connect the schema respectively.
If the user selects France --> It should connect Schema1
If the user selects Germeny --> It should connect schema2.
Used: EclipselinkYou may want to have a different persistence unit for each country, then you just need to switch persistence units, and can put the schema in your orm.xml file.
You may also want to investigate EclipseLink multi-tenant support,
http://www.eclipse.org/eclipselink/documentation/2.5/jpa/extensions/a_multitenant.htm
You can the schema in a persistence unit in code using a SessionCustomizer and the tableQualifier. -
Schema name not present on filename for "Save Package Spec and Body"
In versions previous to 3.0 EA, the filename defaulted to schema.object.sql when using the "Save Package Spec and Body" on the right click of the package/body. This appears to have disappeared. Also, it now defaults to the .PLS ext/type, which I prefer to save them as .SQL (which i can override, but it would be nice in the file type dropdown). Also, I had posted a suggestion about the actual file not including the schema name prefixing the object name when using the "Save Package Spec and Body". i.e. it does create or replace package reader_package instead of what it should be doing which is create or replace package schema.reader_package
Would be nice indeed having the real name as default, and all supported PL/SQL types (as in the preferences) in the extensions dropdown.
As for the schema name inside, I reckon that would do damage for more users than it would do good for others. But a preference would be best of course.

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!
PaulHi 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.

How to parameterize the schema name in APEX
Hi,
How to parameterize the schema name in APEX , in order to access different tables from the respective schema.
For example:-
select NAME display_value, CODE return_value
from paramSchema.DESC_LIST WHERE SELECTION_FLG = 'Y'
order by 1
in the above code, paramSchema will be replaced with the actual schema name duing runtime. I tried doing so by some hidden fields on page, but it didn't worked out.
I took the schema name from the respective server as per the IPof the server.
stored in a hidden field named as schema.
And replaced the same in place of schema name. But no luck.
select NAME display_value, CODE return_value
from :schema.DESC_LIST WHERE SELECTION_FLG = 'Y'
order by 1
Please help me in shorting it out.
Thanks,
AnuradhaHi
In order to do that, you would need to use dynamic SQL by changing the report type to PL/SQL Function Body Returning SQL Query and have code along the lines of
DECLARE
l_sql VARCHAR2(32767);
BEGIN
l_sql := 'select NAME display_value, CODE return_value
from '||:schema||'.DESC_LIST WHERE SELECTION_FLG = 'Y'
order by 1';
RETURN l_sql;
END;However, by doing this, you lose alot of flexibility. The other options would be...
To have seperate report regions that are conditional on the value of the variable.
To use a WITH clause at the tope of the query like...
WITH src_data AS
(SELECT * FROM schema1.my_table
WHERE :schema = 'schema1'
UNION ALL
SELECT * FROM schema2.my_table
WHERE :schema = 'schema2')
SELECT *
FROM src_dataOther than that you could look at using synonyms and doing something similar.
Hope this helps.
Cheers

Hi,
I was looking at DatabaseMetaData::getColumns() while searching for a way to get a table's column names and I run into these ugly params catalog and schemaPattern. Of course nowhere on the sun's site could I find a definition of these terms although they're used quite often in the API documentation. So I turned to a specific DBMS provider and found out that catalog is a fancy term for the system metadata. But what about the String schema param? I usually see a table's schema referred to as the "structure" of the table, what columns it contains of which types. But I've never known this "schema" can have a string name. Anyone so kind to explain it to me or better point me to a text that has definitions and explanations of the concepts used in the JDBC API documentation? And more generally for JDK where do you folks usually go when you want a simple explanation of how things work, not the dry listing of function and parameter names? Look at MSDN for example, it is both a good reference and a reasonable self-contained tutorial. Not that I praise Microsoft but...
BTW I found that probably ResultSetMetaData is more suitable for my initial purposes, but still the questions bother me. So if you have any suggestion please let me know.
Thank you in advanceTo answer your question, what is a table schema name?, it is the name of the schema that the table belongs to. If you have an Oracle database, MYDB, it will have at the very least two users which are SYS and SYSTEM, these are schema names, there are objects that exists in their schema. If you create a new user, JAKE, and then create a bunch of objects as JAKE, these objects are said to belong to the JAKE schema. All objects are like this, not just tables (indexes, sequence tables, triggers, etc.).

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
AngelinaAngelina,
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.
