I am about to pass 1Z0-051 and have been cramming. Ran across this scenario: Create or replace view. Correct answer: allows insert from view in multitable insert statement. Can I actually insert data from a view? My understanding is no data actually exists in a view. This has created a cavernous feeling of inadequacy.

create or replace procedure my_proc(p_user in varchar2) is

Suppose I execute my_proc many times and for multiple values of p_user. For performance reasons, will l_query be stored in the cache as I am using bind variables or it will not since I have the concatenation with p_user value ?

My local currency is INR, I need to write a query to convert the foreign currency to loacl currency INR.In my case i need to write aSQL for a view.It should not implement through PL/SQL
I have a table as shown below,
SQL> select * from Main_Table;
AA

SUB1
SUB2
Here the SUB1 and SUB2 are "tables" and are similar in their structure. The "Main_Table" will be update dynamically and the no of rows in this table will vary.
Now my question , i need to create a view which will have all the rows from these tables ,in the current case it is something like
create or replace view sample
as
select * from SUB1 union all
select * from SUB2
How can this be achived. I tried as shown below:
spool file_to_exe.sql
select 'select * from ' || AA ||' union all ' from Main_table;
spool off
i will end up in a union all "extra" , if i do like this.
how can achieve this ?..

Create materialized view city-A_db_MV
refresh fast
select * from cityA.Tablea@city-Adb
When i select from city-A_db_MV, it showed the complete table-A of city-A database.
Now if we make any changes to City-A table at the Master site, will it be propagated automatically to the MV site.
I guess we need to create jobs to push / or refresh fast .. isnt it. But exactly how to do it is a question.
Secondly if we make a replication group at Master site at city-A db, how do we refresh that Group and how to monitor whether it is refreshing on time or not? do we need to see the jobs every now and then.
but still a lot of questions unanswered, even though i had read the documents earlier.
1-The MView was created without identifying that after what interval it will be fast refreshed.
2- How to Manually refresh it. Does it support On Commit, I think it is not.
3- Where should be we make a group and then add the table to that group and refresh that group.
Should this group belongs to the Master Site or to MV site?

View 3 Replies View RelatedI have to create a materialized view for a table which does not have index on any field.
While creating a Mview i am getting an error "TABLE DOES NOT HAVE THE PRIMARY KEY CONSTRAINT".
application developers do not want to create an index on the base table onto which MView is to be created.
is there any way to create a materialised view for the table without index, or is it necessary to have the index on the base table before creating MView on it.
How I can create a Materialized View without having any data in it.
For e.g.
I create a Materialialized View based on a View.
CREATE MATERIALIZED VIEW test_mv

AS
SELECT * FROM test_view
In the above case the data fetched by the view test_view gets stored in the Materialized View test_mv. Suppose I want materialized view test_mv to get created with all the columns of test_view but not the data. I will refresh the materialized view test_mv later for data as and when required.
