SQL & PL/SQL :: Generate DDL Scripts To All VIEWS From A Specific Schema
Mar 8, 2013
My requirement is to Generate DDL Scripts to all VIEWS from a Specific Schema.For that I Used Below Shown Script.
SELECT DBMS_METADATA.get_ddl ('VIEW', view_name)
FROM user_views;
I Got The Out Put as Show below,
CREATE OR REPLACE FORCE VIEW "PSDBA"."CV_VW" ("EMPNO",
"ENAME",
"HIREDATE",
"ORIG_SALARY",
"CURR_SALARY",
"REGION",
"MANAGER_ID",
"COMMISION",
"CV"
);
But My Question Is How to Filter The SCHEMA NAME From The Received OutPut Script.

I need to generate a list of the programs on all channels for a specific day showing the channel number, supplier, package, program name, rating code, and show time. This will be similar to a program guide, only not package specific. This is a date-driven report, therefore it should only display programs for a single date specified. This is what I have but I cannot get it to run.
CREATE VIEW PROG_LINEUP AS
SELECT DISTINCT S.PROGTIME AS "SHOWTIME", S.PROGNAME AS "PROGRAM TITLE",
C.CHNUM AS "CHANNEL #", SU.SUPNAME AS "SUPPLIER", R.RATING AS "RATING"
FROM SCHEDULE S, CHANNELS C, SUPPLIERS SU INNER JOIN
PROGRAM P ON P.PROGNAME = S.PROGNAME INNER JOIN
CHANNEL_PACKAGE CP ON CP.CHID = S.CHID
INNER JOIN RATING R ON R.RATINGID = P.RATINGID
WHERE S.PROGTIME = '18-DEC-10'
ORDER BY S.CHID;

We are using erwin to generate Er diagram.But with that tool unable to generate the ERD for specific object.Or suggest any other tool from which i can generate the ERD of specific object.
i.e. Lets take an example.
I have a table with one primary key and 10 foreign keys. So now if i select the main table the tool should draw the ERD based on the Constraints ('P' and 'R') so all the different table which have the relation those table should only display. Right now we are getting all the tables ERD(more than 1500 tables) which is not neccesary.

is there some open source or free tool which can graphical display V$ Views. Can TOAD do that in a good maner?
in UNIX there is the "sar" command, but a Java tool "ksar" for displaying the statistics in user friendly fashion.

I have a created a materialized view which is based on a view on remote database. Now how do I refresh the view.
Materialized view is created by
CREATE MATERIALIZED VIEW mv_employee_name
AS SELECT EMPLID, EMPL_NAME
FROM VEMPDATA@REMOTEDB
WHERE REGION = 'US';
I am wondering how the refersh happens or how do I specify the refresh clause.REFRESH FAST option is looking for VIEW LOG on the master table but in this case its a remote view, so I cannot create any object on remote db.

I have a database which consists of various orders and various field.
I have a variable called createddatetime . I want that whenever i should run the database it should display records from
Yesterday 06:00:00 am to Current Date 05:59:59 am
Now to implement this i tried to put this syntax
and to_char(Createddatetime,'dd/mm/yyyy HH24:mi:ss') between 'sysdate-1 06:00:00' and 'sysdate 05:59:59'
But nothing comes up
where as definitely there are records between times because when i do and Createddatetime between sysdate-1 and sysdate I see valid records coming up.

I have to convert some existing materialized views (fast refresh) to partition materialized views.
Database version is oracle 10.1.0.4. I have decided to use on prebuilt table option to do the partitioning as it minimizes the time to transfer from the master site.
1) stop replication
1) create interim tables with similar structure as the materialized views
2) transfer all data from the materialized views to the interim tables
4) script out the materialized views structure and add in on prebuilt table option in the scripts
5) drop the materialized views
6) rename the interim tables with the same name as the materialized views
7) run the scripts to create the materialized views with on prebuilt table option
8) refresh the newly created materialized views -> it should take a short time since I am using on prebuilt table option
But I am facing one major issue. That is if I drop the materialized views, the materialized view logs of the master tables are purged. When the materialized views are refreshed fast, there are some data missing. the data that are purged out when the materialized view are dropped.
Do you happen to know other ways that existing materialized views can be converted to partitioned materialized views? Do you have any workaround to prevent the materialized view logs from being purged?

I want to import a schema from one database schema to another schema b from db STBTST to STATST and from schema CMSSTAGINGB to CMSSTAGINGA
I first want to test this to my own schema (mvanmannekes) CMSSTAGINGA is filled at the moment.
So i've created a dump from STBTST-CMSTAGINGB For importing im using this statement:
impdp mvanmannekes/password schemas=cmsstagingb remap_tablespace=cmsliveb_data:cmslivea_data
remap_tablespace=cmsliveb_index:cmslivea_index
remap_schema=cmsstagingb:mvanmannekes directory=expdp_dir dumpfile=cmstagingb.dmp
I'm getting this:

We have an application with many separate databases (one per customer). Given they share the same business requirements (service hours, change mgmt etc), we're interested in potentially consolidating the separate DBs (which are relatively small) into separate schemas within a fewer no of databases to reduce the overhead.
Our issue is that the application is hard-coded to use a specific administrator and application connection user name. Changing this is unfortunately not an option.
Given this limitation, is there any possibility to map a generic user into a customer-specific schema based on the database service that they connect to? Each customer connects to different database services but may use the same user name. We considered using private synonyms but this seems to acheive the opposite (i.e. many different users could connect and map to a single users schema). One thing to point out is that where there is a single user name, it is acceptable for a single password to be used across the different customer DBs as they will be a single admin/user.

A user is using an ad hoc tool similar to SQL Developer called PeopleSoft Application Designer.
He creates a connection to the db, then issues an alter session set current_schema = 'restricted_schema'. The connected user does not have direct privileges on the "restricted_schema" which they call SYSADM.
After changing the schema context in that manner he creates objects in SYSADM. A schema trigger is then fired and grants privileges on the new objects created in SYSADM. Doing the same in either SQL Plus or SQL Developer does not fire the schema trigger.
I think SQL Plus and SQL Dev are working as they should. Altering the session like that does not change your identity - just the schema context. But, when you examine v_$session, the connection with this other tool looks exactly the same as one from SQL Plus or SQL Dev when changing the schema context in the session.
Instead of trying to figure out what this other tool is doing, is there any way for that schema trigger to fire when using this process from one of our tools?

I am writing a checker that should hit all the views one after other in database and report if there is an SQL error ( Page: Data cannot be retrived from the view XYZ).
The query I am running is
"select * from $view fetch first 1 rows only".
better query which runs faster as I have to query all the views in db in the script ( script runs every 10 mins on cron).

I have a table tblcustomer and a view called vworder. I need to create a trigger such that any data being added into vworder first checks if the field customerid has the data in customerid of tblcustomer.. all it has to do is spit out a error "Customer ID not found"
So I created a view such as
Quote: create or replace TRIGGER trig_order
BEFORE INSERT OR UPDATE ON vworder
FOR EACH ROW
DECLARE
cust_id VARCHAR2(20);
BEGIN
SELECT customerid INTO cust_id FROM tblcustomer WHERE customerid = :new.customerid;
EXCEPTION
WHEN NO_DATA_FOUND THEN
Raise_application_error(-20000, 'Customer ID Does Not Exist');
END;
But it comes with error
Quote: ORA-25001: cannot create this trigger type on this type of view 25001. 00000 - "cannot create this trigger type on views" *Cause: Only INSTEAD OF triggers can be created on a view. *Action: Change the trigger type to INSTEAD OF.
I am not an expert at all and I need to finish this today itself.

I have a table "tl" which is partitioned--say 30 partition and for each partition there is a seperate view like as follows
create view view_t130 as select * from tl partition (p30);
create view view_t129 as select * from t1 partition (p29);
.
.
.
create view view_t101 as select * from t1 partition (p01);
my question is how to use hints on this table if your are using view to access the data from internal table.
Normal structure is if i don't wrong:-
index( <<view name|view alia name>> <<table name|table alias name>> name of index)
Consider my case
select * from view_t130 where <index_column> --not picking up index
i want to give expicit index hint.so i used the same structure that i specified above but it didn't work.
select /*+ index( view_t130 t1 <index_name) */ * from view_t130 where <index_name>
how to give explicit index hint..but one constraint is i cannot give any alias names for internal tables because those(view structure) are generated by predefined scripts..so it's not possible to change it.
