HTML DB application using table in a different schema

I need to create a new HTML DB application. The table is in a different schema than mine. The DBA granted me rights to see it and I can see it from iSQL. HTML DB does not give the alternative of selecting this table.

This thread covers your issue.
New to HTML DB, have questions about service admin and schemas
Ask your DBA to add workspace to schema mapping.

Need to build a form based on a table in a different schema

Hello all,
I am still new to APEX. I have been playing with it for a few days.
I have an APEX user 'demo' whose default schema is demo1.
But I need to create a form that can insert,update and delete based on table 'employee' in schema demo2.
Demo has all the rights on employee table in demo2. I also assigned the demo2 schema to demo user's workspace.
But when I am building the form, demo1 is th eparsing schema, but in table/view owner only demo1 is available. I don't see demo2 even though I assigned it to demo user's workspace.
Is it possible to build a form based on a table in a different schema? I tried creating a synonym, but it doesn't show up in the list of tables to select from.
I don't want to create views or anything because there are many tables in different schemas and it's not possible to go on creating views or such for each one.
I was able to access th etable in a report though by prefixing the table name with the schema name.
I would appreciate if someone could point me in the right direction.
Thanks!

Varad,
Thank you for the explanation. So from what I understand, every time I create a form or report based on a table in a different schema, just change the parsing schema in application definition to the new one and create the form or report. So this way my forms and reports or whatever can be based on different tables in different schemas and they would run fine when deployed in a runtime environment (provided the appropriate privileges are there on the objects in context)?
I tried this and I was able to see the different schema and select the table and create the form. I haven't tested in runtime though.
Seems like a feasible option, need to test all scenarios though. If this is a feasible solution then there is no need to create synonyms or views (I am not talking about others' scenarios such as security etc) etc. Just appropriate privileges will do it.
Thanks Varad. Have you used this way of creating a form in your apps? I need to explore more to see if it breaks anything.
So, every time I need to select an object, say a table, in a different schema I need to temporarily change the parsing schema to that schema in the application definition? Is that a correct statement?
I will leave the thread open to see if anybody has any comments.

Moving Subpartitions to a duplicate table in a different schema.

+NOTE: I asked this question on the PL/SQL and SQL forum, but have moved it here as I think it's more appropriate to this forum. I've placed a pointer to this post on the original post.+
Hello Ladies and Gentlemen.
We're currently involved in an exercise at my workplace where we are in the process of attempting to logically organise our data by global region. For information, our production database is currently at version 10.2.0.3 and will shortly be upgraded to 10.2.0.5.
At the moment, all our data 'lives' in the same schema. We are in the process of producing a proof of concept to migrate this data to identically structured (and named) tables in separate database schemas; each schema to represent a global region.
In our current schema, our data is range-partitioned on date, and then list-partitioned on a column named OFFICE. I want to move the OFFICE subpartitions from one schema into an identically named and structured table in a new schema. The tablespace will remain the same for both identically-named tables across both schemas.
Do any of you have an opinion on the best way to do this? Ideally in the new schema, I'd like to create each new table as an empty table with the appropriate range and list partitions defined. I have been doing some testing in our development environment with the EXCHANGE PARTITION statement, but this requires the destination table to be non-partitioned.
I just wondered if, for partition migration across schemas with the table name and tablespace remaining constant, there is an official "best practice" method of accomplishing such a subpartition move neatly, quickly and elegantly?
Any helpful replies welcome.
Cheers.
James

You CAN exchange a subpartition into another table using a "temporary" (staging) table as an intermediary.

NOTE : Since your source and target tables are in different schemas, you will have to move (or copy) the staging table STG_part_subpart from the first schema to the second schema after the first "exchange subpartition" is done. You will have to do this for every subpartition to be exchanged.

How can i import tables from a different schema into the existing relational model... to add these tables in the existing model? plss help

how can i import tables from a different schema into the existing relational model... to add these tables in the existing relational/logical model? plss help
note; I already have the relational/logical model ready from one schema... and I need to add few more tables to this relational/logical model
can I import the same way as I did previously??
but even if I do the same how can I add it in the model?? as the logical model has already been engineered..
please help ...
thanks

Hi,
Before you start, you should probably take a backup copy of your design (the .dmd file and associated folder), in case the update does not work out as you had hoped.
You need to use Import > Data Dictionary again, to start the Data Dictionary Import Wizard.
In step 1 use a suitable database connection that can access the relevant table definitions.
In step 2 select the schema (or schemas) to import. The "Import to" field in the lower left part of the main panel allows you to select which existing Relational Model to import into (or to specify that a new Relational Model is to be created).
In step 3 select the tables to import. (Note that if there are an Foreign Key constraints between the new tables and any tables you had previously imported, you should also include the previous tables, otherwise the Foreign Key constraints will not be imported.)
After the import itself has completed, the "Compare Models" dialog is displayed. This shows the differences between the model being imported and the previous state of the model, and allows you to select which changes are to be applied.
Just selecting the Merge button should apply all the additions and changes in the new import.
Having updated your Relational Model, you can then update your Logical Model. To do this you repeat the "Engineer to Logical Model". This displays the "Engineer to Logical Model" dialog, which shows the changes which will be applied to the Logical Model, and allows you to select which changes are to be applied.
Just selecting the Engineer button should apply all the additions and changes.
I hope this helps you achieve what you want.

How to gather table stats for tables in a different schema

Hi All,
I have a table present in one schema and I want to gather stats for the table in a different schema.
I gave GRANT ALL ON SCHEMA1.T1 TO SCHEMA2;
And when I tried to execute the command to gather stats using
DBMS_STATS.GATHER_TABLE_STATS (OWNNAME=>'SCHMEA1',TABNAME=>'T1');
The function is failing.
Is there any way we can gather table stats for tables in one schema in an another schema.
Thanks,
MK.

You need to grant analyze any to schema2.

Need query to compare the columns of 2 diff tables of 2 different schemas.

There are two different tables(sample1, sample2) in different schemas(s_schema1, s_schema2).
I want the query to compare the columns of two different tables of two different schemas and provide whether the data as well as the count of data in
the column are same .
if not provide the data which is not similar in the columns of two different table.
NOTE:
I need queries for both the cases.
(i) The datatypes in columns of two different tables are same.
(ii) The datatypes in columns of two different tables are diffrent.

Joining two tables in two different schema

Hi All,
I have a requirement to join two tables in two different schema. How to join these two tables in view object.
Many thanks in advance.
Regards
Kaushik Gopalakrishnan

1) If these tables are in one and same database instance, then you can join them by specifying the fully-qualified table names (inlcuding the schema name), for example:
SELECT ...
FROM schema_A.table1 T1, schema_B.table2 T2
WHERE T2.parent_code = T1.code
AND ...2) If the tables are in different database instances, then you can create a database link in one of the databases and access the table from the other database via the DB link, for example:
SELECT ...
FROM schema_A.table1 T1, schema_B.table2@mydblink T2
WHERE T2.parent_code = T1.code
AND ...3) If the tables are in different database instances and there is no option for DB links, then you cannot join the tables in an ADF ViewObject.

Any way to use a single application but point it to different schemas?

From the searching I have done, it appears that when an end-user runs an application, it can only be associated with a pre-defined schema, which I guess I just need confirmation of. What I was hoping to be able to do was either dynamically change to a different schema at run-time, or create an end-user that is associated with a different schema than the one the application is associated to so the user could use the one application but access a given schema.
The scenario is that in our production environment, we need to maintain a separate schema for each client we manage data for. But we'd like to maintain one application end users would use but could run against any one of the client schemas. However, it seems that we willneed to make a copy of the application within the production workspace for each client schema that would be the owner schema if I understand how this works. Thus, if we have 7 different schemas we would have to have 7 copies of the application, one associated with each application.
Thanks in advance!

Thanks Scott for quick response.
We will go with different workspace for each schema.
Just to give you quick background of my requirement. We have a 3 oracle E-Business versions (11.5.8, 11.5.9 and R12 in future) and APEX installed on another 11g database. We don't want to installed APEX on EBS database because of DB patching issues, our EBS 11i database version is 9i DB, future oracle EBS supoort and at the same time we want to use APEX 3.1.2 with 11g. We want use APEX for custom EBS Web UI development.
We are planning to create separate schema on APEX database for each EBS instance and DB link which points to EBS database. Under APEX schema we are planning to create a view (on our custom table which are same across all EBS instances) using DB link under each schema.
We will develop APEX application under one of the workspace and they deploy to other workspaces. We have also looked into creating APEX pages based on pl/sql procedure and we can do dynamic sql to query data from EBS instances. But its lots of code (create pl/sql api for every table) and we can not take a advantages of some of the APEX build-in wizard like master-detail, APEX record locking etc
Based on your APEX experience; Do you think this the way we should go? OR Is there any better way?.
Thanks in advance

How to find the list of un used table names in a schema?

Hi,
I have a doubt in Oracle. The doubt is that If we are using any tables in Function Or Proc.... Then...We can list all those used table names from USER_DEPENDENCIES system table. Right...
But, If the table is used with Execute Immediate Statement, then, those table names are not coming out with USER_DEPENDENCIES system table. Because they are identified at run time and not compile time.
It is fine. And I agree.. But, If I want to list out those tables also...then...How to do? Any idea?
I think ‘USER_SOURCE’ system table may not be the right one. If there is any other system table avails for this purpose...then..it would be very grateful to extract right...
So I am wanting that exact system table.
Please let me know about this, if you have any idea or check with your friends if they have any idea.
Regards,
Subramanian G

Hi Guys,
Thanks for all your answers.
Yes....You are all right. We can list out the used tables upto certain extent. Anyhow, I have done some R&D to derive the SQL's which is given below:
SELECT TABLE_NAME FROM USER_TABLES
MINUS
SELECT DISTINCT UPPER(REFERENCED_NAME)
FROM user_dependencies
where
referenced_type='TABLE' and UPPER(NAME) in
select distinct UPPER(object_name) from user_objects where UPPER(object_type) in
'MATERIALIZED VIEW',
'PACKAGE',
'PACKAGE BODY',
'PROCEDURE',
'TRIGGER',
'VIEW',
'FUNCTION'
UNION
SELECT UT.TABLE_NAME FROM
SELECT TABLE_NAME FROM USER_TABLES
MINUS
SELECT DISTINCT UPPER(REFERENCED_NAME)
FROM user_dependencies
where
referenced_type='TABLE' and UPPER(NAME) in
select distinct UPPER(object_name) from user_objects where UPPER(object_type) in
'MATERIALIZED VIEW',
'PACKAGE',
'PACKAGE BODY',
'PROCEDURE',
'TRIGGER',
'VIEW',
'FUNCTION'
AND REFERENCED_OWNER=(SELECT sys_context('USERENV', 'CURRENT_SCHEMA') FROM dual)
) UT,
( SELECT * FROM USER_SOURCE
WHERE NAME IN
( SELECT DISTINCT NAME FROM USER_SOURCE
WHERE TYPE NOT IN ('TYPE')
AND
UPPER(TEXT) LIKE '%EXECUTE IMMEDIATE%'
) US
WHERE
UPPER(US.TEXT) LIKE '%'||UPPER(UT.TABLE_NAME)||'%'
AND
(UPPER(US.TEXT) NOT LIKE '%--%')
The above SQL Query can list out unused tables by checking the Dynamic SQL Statement also upto some level only.
Once we extracted the list of unused tables, having a manual check would be also greater to verify as it is should not impact the business applications.

Subramanian G

Compare table structures in different schemas. help please

Hi all,
I have a question...
I have tables on different schemas some thing like
Schema A
Table 1
Table 2
Table 3
Schema B
Table 1
Table 2
Table 3
Now situation is Table 1 and Table 2 will have similar structure or Table 1 in Schema B will have additional columns.
like so... on... for all other tables...
example !
Schema A:
Desc Table 1;
Name                                  Type            Null
No                                Number            Notnull
Name                           Varchar2(10)     Not null
Fee                              Number (10,2)   Not null
Scheam B;
Desc Table1;
Name                                  Type               Null
DX_No                                Number            Notnull
DX_Name                           Varchar2(10)      Not null
DX_Fee                              Number (10,2)   Not null
comments                          Varchar(2)        Now I need to write a procedure sort of thing to compare these tables which are in different in column names in both schema and get it exported to Excel sheet.
and here thing is first three columns SHOULD BE TREATED AS SAME even though prefix of DX_ exist since REST OF THE PART OF COLUMN NAME IS SAME.
and in same way commets is new coloumn in schema B only..So that should be highlighted excel sheets..
I am not sure how OAD or SQL Developer handle this...Is there any plsql block I can write to do above..
Thanks in advance..

An example of one method (this is just a starting point, you'll have to build it out to suit your needs).
create table emp as select * from scott.emp where 1=0;
alter table emp add (junk number(1));
select
      t1.column_name as t1_column_name
   , t2.column_name as t2_column_name
from
   select column_name
   from
      dba_tab_columns
   where
      table_name = 'EMP'
   and
      owner       = user
) t1
full outer join
   select column_name
   from
      dba_tab_columns
   where
      table_name = 'EMP'
   and
      owner       = 'SCOTT'
) t2
on (t1.column_name = t2.column_name)
where
   t1.column_name is null
or
   t2.column_name is null;
T1_COLUMN_NAME                 T2_COLUMN_NAME
JUNK
1 row selected.
TUBBY_TUBBZ?If you need to remove prefix's ... you would just do that in the select list (using regexp_replace, translate, substr, whatever you think is appropriate for your situation).
Edited by: Tubby on Nov 6, 2010 12:38 PM
Forgot to mention that this code will report differences between two schemas, regardless of where the additional columns reside ... if you have a 'master' schema that is the definitive source, then you would want to use the query provided by Xtender.

Replicate using streams to a different schema

All,
I'm performing replication using streams, I have read the doc and steps by steps notes on metalink getting the replication successfully.
But now, I want to do the same but on differents schemas ie.
source DB: Schema= A Table=test
Destination DB: Schema= B Table=test
On both databases the schemas are basically the same but with different names.
What changes o additional steps I need to perform in order to complete the replication?
Thanks in advance..!

There are demos of both Change Data Capture (superior for what you appear to be doing) and Streams in Morgan's Library at www.psoug.org. Some of them duplicate exactly what you describe.
PS: There is a specific Streams forum. In the future please post Streams related requests there. Thank you.

Acess table located on different schema

hi ,
oracle 10.2.0.1.0
I have production database and i'm able to access video_asset_language located on different schema (CAM) of same db.there is synonym for the table here (at production ) .If I query user_synonyms the last column DBLINK has entry here.
Now from development DB I created a synonym for the table video_language_asset located in CAM schema. it says "translation error " . Synonym is created but not able to fetch from the table. If I query user_synonyms the last column DBLINK has no entry here.
Please suggest what I need to do .
thanks
Kishna

- Verify you have been granted select access to the table (from user_tab_privs_recd)
- Verify the database link exists, if not create it (get the definition using dbms_metadata.get_ddl
- get the correct synonym definition, and replace the synonym when (get the definition using dbms_metadata.get_ddl)

Tables in a different schema not visible from function

I'm getting a really weird error in a function that I wrote. I have user "A" who has access to schemas for users "B" and "C". I need to update a table in schema "B" with data from schema "C". So, I created a function that selects information from a table in schema "B", uses that information to find the data of interest in schema "C" and then I update the table in schema "B" with the information I just looked up in schema "C". Clear so far?
Anyway, when I try to create the function (I"m using SQLPLUS for all of this) I get an error message that the tables I am referencing in schema's "B" and "C" do not exist. However, if I modify the function so that I select a column that doesn't exists from a table in schema "B", then I get an error pointing this out to me. So, it seems weird that I have enough visibility into schemas "B" and "C" to know if I am accessing data by the correct column names, but when the column names are correct, I get an error message saying "table or view does not exist". I am in my development environment, and user "A" is granted the "DBA" role.
So, here is my function. Note that I have qualified the table names with the schema owner (i.e. B.KPF_FOLDER_ITEMS) Any tips would be greatly appreciated. Database is 9i

How to export and import dependent tables from 2 different schema

I have a setup where schema1 has table 1 and schema 2 has table2. And table 1 from schema1 depends upon table 2 from schema 2.
I would like to export and import these tables only and not any other tables from these 2 schemas with all information like grants,constraints.
Also will there be same method for Oracle 10g R1,R2 and Oracle 11G.
http://download.oracle.com/docs/cd/B12037_01/server.101/b10825/dp_export.htm#i1007514
Looking at this For table mode it says
Also, as in schema exports, cross-schema references are not exported
Not sure what this means.
As I am interested in only 2 tables I think I need to use table mode. But if I try to run export with both tables names, it says table mode support only one schema at a time. Not sure then How would the constraints would get exported in that case.

Move table to a different schema

How can i move a particular table from one schema to another.
I have no mutual depenencies on anyother tables.

Couldn't you just use CREATE TABLE <tablename> AS SELECT * FROM oldschema.<tablename> in the new schema, then drop the table in the old schema? Or, is your situation more complex than that? You might need to create a synonym to point to the new table from the old schema...
For this to work, you'll need to make sure that the new schema has select privileges on the old schema's table. If it doesn't, while logged into the old schema, use:
GRANT SELECT on <tablename> to <newschema>;Then, if you still need to access the table from the old schema once it's moved, you'll need to grant those privileges from the new schema:
GRANT SELECT on <tablename> to <oldschema>;(Though, using roles is a better option than granting privileges directly to a schema...)
