Table based on Public Synonyms

I have 2 schemas and have created public synonyms and given access from the 1 schema to the 2nd schema.
When I create Page / Region of type Report and form (or form) in schema 2, the table name does not accept the public synonyms defined in schema 1. I can create a report region manually using the the SQL Report and select col1, col2 from tab1_of_schema1 but while using the wizard and selecting the table, am unable to use the table ? I even tried schema1.tab1_of_schema1 but it gives " * Table / View does not exist." error. Why is this ?
Is this a limitation ? I do not want to create views and write instead-of triggers.

This was raised during the evaluation of 2.2, and this was the response:
Sorry, don't know if this is already addressed, (but i cannot test this in 2.2, with my scenario, so would appreciate you mention if it is handled). I have 2 schemas, schema1 and schema2. There are tables in schema1 which have public synonyms and grant all access to schema2.
While creating a new application in schema2 and creating Page, we cannot select public synonyms defined in schema1, and have to unnecessarily create views in schema2 (this is not nice for us). Even if view is created, it gives an error saying " Source tables for forms and tabular forms must have a primary key. " why should views have primary key ? Either do not allow views there, or ask for the primary key (like in create region). Sequences defined in schema1(again public synonyms) are not accessible.(we have to write triggers or custom pl/sql for the same).
Response
We do not do very well with objects that are not owned by the schema assoicated with your current application. I have logged an enhancement request for 3.0 to see if we can improve this all around.

View Owner and table name of public synonym

A schema user has created a public synonym of a table to another user, say U1.
How could U1 view all the details of the public synonyms, such as a list of all the public synonyms, and the corresponding owner and table names?

select synonym_name
, table_owner
, table_name
from all_synonyms
where owner = 'PUBLIC'
order by 2, 3
/Be warned that this is likely to be a very long list, so you might want to also filter on
and table_owner not ('SYS', 'SYSTEM')or similar.

Do I need to deploy Public Synonym in Target Schema?

Hi,
I need to develop and deploy a mapping. I need to use source table in source schema but a Public Synonym for a terget table. This destination table for the public synonym is not target_schema where mapping is to be deployed. Do I still need to deploy the public synonym into my target schema where mapping is or not? I was 3wandering since its a public synonym and the actual destination table is already in database I may not have to deploy this synonym. Thanks for the help in advance..

OWB does not currently directly support public synonyms. You will have to deal with these synonyms outside OWB and if you use the synonym from a mapping you can trick OWB to use it by creating and using a dummy table in the mapping.

Problem to resolve existing public synonym ?

Hello,
I would like to know if there are some circumstances under which a valid
public synonym on a table still brings up
ORA-00980 (in Oracle Reports).
The situation is this:
We have two main schemas, one is crowded with tables and all stored
procedures, and one with a single but
large table. This table has a public synonym and can be selected from in
SQLPlus and so on. No [schema.] is needed.
But in Oracle Reports, the synonym "cannot be resolved". All other tables
can be selected, but the update on the
special large table failes.
Or is Reports behaving different from SQL*Plus ? One of our developers gave
up using synonyms
and started adding [schema.]table to the statements.
Has anybody here made similar observations ?
I re-created the public synonym last night, because we thought it maybe caused by our
recent db upgrade, but the situation did not change.
What could it be ?
ThanX in advance.
Jan

Jan,
You didn't state what version of the database you are using, nor whether you are accessing the table in the Reports data model or in a PL/SQL trigger. There are known bugs about when accessing a synonym under specific conditions, although a common theme seems to be when accessing from within a PL/SQL block. You should contact Oracle Support and work with them to resolve this issue for your specific situation.

Stewart

Create a view based on a public synonym

Hi I'm trying to create a view based on a public synonym, but getting "ORA-01031: insufficient privileges" error.
When i retrieve records from the same public synonym, i could able to do so. But when i try to create a view based on that synonym, it is not possible. Why is it? Can anyone please explain?

Public Synonyms for Nested Tables - Insertion Problem

Hi,
we are facing a problem during implementation. Our DB set up
is , we will be having two schema named OWNR and COPY.
In the schema, OWNR we have to create all the tables,
types,procedures, packages and obj.....This schema will have
both DDL and DML privileges.
In the schema, COPY we are not supposed to create any tables,
objects. We have to create public synonyms for all the tables,
types, procedures... in OWNR and grant ALL privilege to the
schema COPY.The schema, COPY will have only DML privileges.
The problem is we have some nested tables in our application.
When I try to insert into the synonym which is created for the
nested table, it is not allowing me to insert..The whole
implementation is stucked..Please help.The scripts are given
below.......
We have a type name SITA_ADDRESS_TY which is used by the nested

Our middle tier can connect only to COPY schema alone..Is there
anything to be done in the DBA side to achieve this??.
Please help from your valuabe experience...Or can you ask your
collegues if they have got a soln to this probs..Our
implementation team is stucked with this...
Thanks

Hi
I am not sure but maybe you need to use this command:
SQL> insert into ums_sita_address values
('EK','EK','DXB',SITA_ADDRESSES_TY());
SITA_ADDRESSES_TY() instead SITA_ADDRESSES_NT

Cannot see columns for some of the public synonyms

Background Info
I am using the Oracle 8.1.6 JDBC driver and connecting to Oracle 8 database. My plan is to give the user the option to initially select the type of tables that they want to see i.e. USER tables, SYSTEM tables, VIEWS and SYNONYMS. Based on the user selection I first display all the tables (for that type) and for each table selected by a user display the relevant columns.
I am doing this by using the DatabaseMetaData.getTables () and then the DatabaseMetaData.getColumns () methods
Problem
When I use these methods for SYNONYMS I cannot see the columns for lot of the public synonyms. Some the SYNONYMS for which I cannot see the columns are
ALL_JOBS, COLS, CLU, CAT, TABS.
As part of the debugging process, I found a java file OracleDatabaseMetadata.java file (as part of 8.0.4 sample files). In this file I see that calls are being made against ALL_TAB_COLUMNS. For each of the synonym that I am seeing the problem, there are no columns in ALL_TAB_COLUMNS. But when I do a desc ALL_JOBS in SQLPLUS, I get the columns for ALL_JOBS. So now I am confused on what is happening in the 8.1.6 JDBC driver.
Has anyone else run into the same problem.
Thanks

There are some cases where Discoverer cannot determine with certainty that the Totals or subtotals you create will be correct. It flags those totals as Values that cannot be aggregated. Go to Options-> Sheet Format and you can set what string you would like to see placed in those cells that Discoverer determines cannot be aggregated correctly.
Assuming that the blank totals are non-aggregable by Discoverer, there are some things you can do to to alter either your business area or worksheet or calculation that will enable you to get the totals you want. As this analysis takes some time and iterations, it is usually best handled through Oracle Support. Also see the doc and RN references to the EnhancedAggregationStrategy in the Preferences.
Also, given the version you are using it seems that you have just started using 9.0.2. You should strongly consider upgrading to OracleAS 10g (9.0.4) or at least upgrade to the latest 9.0.2 patch -> 9.0.2.54.

Form based on a synonym

Hi,
A simple question : is it possible to create a form based on a synonym? (public, private, no matter)?
Suppose I want to deploy an application within a schema where all the synonyms (with the same names) are pointing to the real schema.
Also, something is telling me that it is not possible because when I create a form region based on table, the lov is only presenting the "real" tables and views.
The last question, if not possible, why isn't it? Many customers are using FORMS with this architecture, it will be a step more to bring them to APEX.
Thank a lot, Bruno-Pierre

Do you suggest anything to get around this? As I mentionned, many customers use the generic schema with synonyms approach so we'll have to be creative!
I could create in the generic schema all the views used by the application (the synonym list). A lot of inconvenients but working...

How to create materialized view based on a synonym

Hi all,
I am trying to create simple materialized view based on a synonym and that synonym is pointing a view in other database (using dblink). I am getting table or view not found error . I am able to select synonym if i use select but not in materialized view. Please help me.
Thanks,

The best way to do this is to create a materialzed view based on the underlying code of the original view. If you don't have this handy, issue the following in sqlplus:
select text
from user_views
where view_name = 'NAME_OF_VIEW'
You can then cut and paste the sql statement into your create materialized view statement.
Please note, you will probable have to set the long parameter to a higher value to reveal the complete statement for example:
SQL> set long 2048

Create a public synonym for a db link - "Connection desccriptor not found".

I want to create a public synonym for a db link.
The existing db link name is tst.world ( which is in db links table and is working fine).
I created the following db link using the following command:
create public synonym "syn.world" for "tst.world";
It created the synonym successfully.
If I try the following, it throws error "Connection desccriptor not found".
select * from [email protected];
It says "Connection desccriptor not found".
Any suggestions.
Thanks in Advance.

Well then, lookup the Documentation on the CREATE SYNONYM statement in the SQL Language Reference manual.
The documentation lists the types of objects which you can create synonyms for.
You can create synonyms for objects referenced across DBLinks.
You cannot create synonyms for DBLinks.

A dynamic table based on run-time created view object -- please help!

Hello!
I'm trying to create a dynamic table based on an run-time created view object. All go ok, but table binding component take the first view/iterator state and don't reflect changes they have. Please, take a look:
1. At run-time the view is being replaced by new red-only one based on query in application module:
getQueryView().remove();
createViewObjectFromQueryStmt("QueryView", statement);
2. Page definition file contains an iterator (using iterator or methodIterator - doesn't matter) binding and table, which binds to the iterator, like:
<methodIterator id="distributeQuery1Iter" Binds="distributeQuery1.result"
DataControl="QueryServiceDataControl" RangeSize="10"/>
<table id="distributeQuery11" IterBinding="distributeQuery1Iter"/>
3. The page code uses <af:table>. But, if I use table binding (it's right) like this:
<af:table var="row" value="#{bindings.distributeQuery11.collectionModel}">
<af:forEach items="#{bindings.distributeQuery11.attributeDefs}" var="def">
the table will never changed (i.e. still show the first view instance).
When I tried to use iterator binding directly (it's bad and cannot provide all needed features unlike CollectionModel from table binding) I saw that table works!
(Code is somehing like:
<af:table var="row" value="#{bindings.myIterator.allRowsInRange}">
<af:forEach items="#{bindings.myIterator.attributeDefs}" var="def">
Why the table binding do not reflect changes in iterator? Or should I use different approach?
Thanks in advance!
Ilya.

I got it to work! I used a hybrid approach comprised of some of your code and some of Steve Muench's AcceessAppModuleInBackingBean example.
In the setBindings method, I execute an app module method that redefines the query, then I used your code to delete and recreate bindings and iterator:
public void setBindingContainer(DCBindingContainer bc) {
this.bindingContainer = bc;
rebuildVO();
The rebuildVO() method looks like the code you provided in your example:
private void rebuildVO() {
DCDataControl dc;
DispatchAppModule dApp;
DCBindingContainer bc;
DCIteratorBinding it;
OperationBinding operationBinding;
ViewObject vo;
DCControlBinding cb;
try {
bc = getBindingContainer();
dc = bc.findDataControl(DATACONTROL);
dApp = (DispatchAppModule)dc.getDataProvider();
// Execute App Module Method to rebuild VO based upon new SQL Statement.
dApp.setDispatchViewSQL();
vo = dApp.findViewObject(DYNAMIC_VIEW_NAME);
it = bc.findIteratorBinding(DYNAMIC_VO_ITER_NAME);
it.bindRowSetIterator(vo, true);
// logger.info("Remove value binding...");
cb = bc.findCtrlBinding(DYNAMIC_VIEW_NAME);
cb.getDCIteratorBinding().removeValueBinding(cb);
bc.removeControlBinding(cb);
// logger.info("Creating new value binding...");
FacesCtrlRangeBinding dynamicRangeBinding =
new FacesCtrlRangeBinding(null,
bc.findIteratorBinding(DYNAMIC_VO_ITER_NAME), null);
// logger.info("Add control binding...");
bc.addControlBinding(DYNAMIC_VIEW_NAME, dynamicRangeBinding);
} catch (Exception e) {
e.printStackTrace();
And my App Module method that redefines the view object looks like this:
public void setDispatchViewSQL() {
String SQL =
"begin ? := PK_BUsiNESS.F_GETDISPATCHVIEWSQL();end;";
CallableStatement st = null;
String ViewSQL = null;
try {
st = getDBTransaction().createCallableStatement(SQL,
DBTransaction.DEFAULT);
* Register the first bind parameter as our return value of type LONGVARCHAR
st.registerOutParameter(1, OracleTypes.LONGVARCHAR);
st.execute();
ViewSQL = ((OracleCallableStatement) st).getString(1);
findViewObject(DYNAMIC_VO_NAME).remove();
ViewObject vo = createViewObjectFromQueryStmt(DYNAMIC_VO_NAME, ViewSQL);
vo.executeQuery();
} catch (SQLException s) {
throw new JboException(s);
} finally {
try {
st.close();
} catch (SQLException s) {
s.printStackTrace();
When I run it I get my desired results. One thing I don't quite understand is why when the page is first rendered it shows the last set of records rather than the first. Now I have to figure out how to put navigation URLS in each of the table cells.
Thanks for your help; I would not have gotten this far without it,
Jeff

DB Links vs. Public Synonyms Security issue

I have been debating on using either a public synonym or a db link for my purpose. I have a dev, test, and prod database. I have applications that have been developed using a public synonym. I know that if I were to switch to db links I would have to go back and change the applications to have access to the tables. I was wondering if it would be more secure to just have the public synonyms with select privilege or have db links. I need to decide if I should use db links for various users in the same DB (e.g. prod) and to use db links from one DB to another. Can someone explain what the security risks are between the two and which would be safer to use?
Thanks

I appreciate that you have taken the time to read my post. The version of the database I am using is 10g. I guess to clarify my post I am asking if someone can provide me advantages and disadvantages of using either public synonyms or db links. I don't know if I am clear, but when I refer to a DB Link I am referring to the following type of access where a client in a database A can access information in a remote database B (e.g. schema1.table2@databaseB). I am not sure what you mean by "Database links are two entirely different technologies that do two entirely different things". But I would appreciate if someone with DBA experience can provide some insight regarding security issues associated with using public synonyms and db links.
Thank you,

What can i do for creating view on a public synonym?

Hi people,
I have create a public synonym for other users object as,
SQL> create public synonym pdep for scott.dept;
Synonym created.
then i tend to create a view on this public syn as,
SQL> create view vpdep as select * from pdep;
create view vpdep as select * from pdep
ERROR at line 1:
ORA-01031: insufficient privileges
I have privilege to create view.also i can create view on a public synonym of my own objects.for ex,
SQL> create public synonym cdep for dept;
Synonym created.
SQL> create view vcdep as select * from cdep;
View created.
what could be the reason behind this?is there any privilege required for me.pls suggest me.
Regards
VIDS

Hi vidusnat!
This is from Oracle's onlinedocumentation:
>
Privileges Required to Create Views
To create a view, you must meet the following requirements:
You must have been granted one of the following system privileges, either explicitly or through a role:
o The CREATE VIEW system privilege (to create a view in your schema)
o The CREATE ANY VIEW system privilege (to create a view in another user's schema)
You must have been explicitly granted one of the following privileges:
o The SELECT, INSERT, UPDATE, or DELETE object privileges on all base objects underlying the view
o The SELECT ANY TABLE, INSERT ANY TABLE, UPDATE ANY TABLE, or DELETE ANY TABLE system privileges
In addition, in order to grant other users access to your view, you must have received object privileges to the base objects with the GRANT OPTION clause or appropriate system privileges with the ADMIN OPTION clause. If you have not, then grantees cannot access your view.

I hope that this will bring a little light into darkness!

DB Link Public Synonym

Hi Guys
I have a public SYNONYM that was created to access a table on the remote database using a DB Link.
We are able to access the DB Link using SQL Plus and the Synonym BUT when the same is used inside the cursor query of a PL/SQL block we get the following error message!
This is driving me crazy... need your expert suggestion :)

Hi,
As I say, when we access the synonym (that links to a table through a DBLINK) we have this issue. The code can be as simple as
DECLARE
var1 int := 0;
CURSOR S1 IS SELECT col1, col2 from TB_DBLINK;
BEGIN
LOOP through Cursor S1
END;
Here the TB_DBLINK is:
CREATE PUBLIC SYNONYM TB_DBLINK FOR TB_DBLINK@DBL1
The TB_DBLINK on the DBL1 is also a Public Synonym... So it means that a Public Synonym is being created for a Public Synonym!
Able to access this using SQL Plus simple select though :(
