Which is better to use of Views and Materialized views so as to have good performance ? Also I need to search for a particular value in the view. Any function in sql to implement this ?
View 3 RepliesIn search queries generally we select 10-25 columns (more can't be displayed on the screen) from 5-10 tables
Say in case of insurance related application, the search might be on policy number, policy holder's first name, policy holder's last name, region, policy type etc.
And not to many columns we are displaying on the screen, say, 4 tables have collectively 4 * 20 = 80 columns, then we are displaying say 12-15 columns with 2-3 columns have aggregates on it.
since the search criteria (e.g. first name, last name, policy number etc.) is not known till last moment it will be a generic dynamic query
Is it possible that instead we create a Materialized view with query with only joining conditions but no filter conditions and selecting only columns to be displayed on the screen and then we will refresh the materialized view (to take care of recent business transactions) and fire refined query with filter criteria on this materialized view
Select col1,col2,col3,col4,col5
From tab1,tab2,tab3,tab4
Where tab1.col1=tab2.col1
And tab2.col2=tab3.col2
And tab2.col2=tab4.col2;
Will it improve performance of the search functionality
I am using apex 4.1. I must hide phone number columns in my IR report, but at the same time the values of that columns should be available to search for using IR Search Field. is there a way to do this ?
if not, that means I have to :
1- Add a text filed P1_PHONE
2- edit my report query to something similar to
> Select * from Table where :P1_phone in (mobile1,mobile2) or :p1_phone is null
3- add button to refresh the report.
but the item P1_PHONE should be on the header of the Report region. is there a way to do this.
I am using theme 23
page template without sidebars
Report template : Reports Region.
how to put the item P1_PHONE on the tab of the page. Just similar to the Search item of in the Application Builder.
can we change the existing materialized view to normal view? if yes how?
View 2 Replies View RelatedI'm trying to create a Materialized View on a remote database from a simple view. The reason is, the data owners don't want to grant explicit tables privileges to external subscribers.
A new schema is created to publish data in the form of a view. I've created mlogs on the master tables, and granted them to the subscriber, but it's still complaining about a missing primary key on the view. A primary key does exist in the master table.
Is there another work around for this situation without having to work inside the data sources' environment?
is it possible to create primary key on view and use this view for creating foreign key .
View 3 Replies View RelatedWe wrote one data load process to load GZ files into Database.during process we will change client facing view definitions to backup table so that we can work on base tables.
This view definition changes are related to FROM and WHERE clause (not columns/type). during load process, client/user may connect to current server and accessing these views. My question is what will be the reflection of changing view definition while user is accessing view?
I created a scenario-
STEP1: Created a view-
create or replace view view_01 as
select object_name from dba_objects union all
select object_name from dba_objects union all
select object_name from dba_objects union all
[code]....
View definition is replaced by new definition while select is executing on that view. select returned number of records as per view definition one.

I would need a SQL script or a command for PLSQL that would search for a keyword %keyword% in all tables of a database instance and in a sepcified schema of a user.
how to do this interactively, without preparing a SQL script with all exisiting tables?
I have an application which deploys the data to Oracle database. It has more than 25 tables and many columns. It does not have any document explaining the deployment, so I am kind of doing reverse engineering here.
I need a script which will fetch the column name or at least table names which will match with either some string or number? I found few examples on net to find out number. But I am struggling to make it work for string.
I can not work on stored proc, as I do not have access to create that on server. So, any script will work.

Assuming I have the following table with its data:
Quote:
| code | description |
| A | $abc + xyz = $cba - 2 |
| B | ($12345 + $12345)/3 |
| C | $poke + $abc = $abc + 456 - 789 |
How can I do a selective search on "description" column for any word that starts with the "$" sign? In the end, this is the resultset that I am expecting:
Quote:
| $ | count of $ |
| $abc | 3 |
| $cba | 1 |
| $12345 | 2 |
| $poke | 1 |
I'm trying to select from table "A" where value1 and value2 match. If the values are not in table "A", try table "B". If the values exist in BOTH tables - only look at the results from table "A".
Table "A" may or may not have "new" data coming into the system.
Table "B" may or may not have "existing" data.
The code I am writing needs to find the "newest" data row for value1 and value2. Eventually the data in table "A" gets "Merged" into table "B" further on in the process.
Supposedly this can be done in a single query using a left outer join and the NVL function, but the person I inherited this from isn't available.
I've been able to get the row back if it exists in "A" or "B", but end up with two rows or no rows if the row exists in both... Arrrg...
I ran this following query and somehow i feel the results are wrong.

We are having this problem of entering duplicated inventory parts in the system which physically refers to the same part. Need to create a select query to search through the list of inventory parts to find out existing parts with similar names.
Requirement is to have a search on a specific character set and it should list even records with 50% of the characters they have entered. Characters can be anywhere in the part name with any case.
For example: input of 'abcd1234' should return the parts with the following name... A nut 234 R49SE B12 A22Hub 156 65 a2 But not... abc 89998AK 47Xbox 360Mauser K98b

View 7 Replies View RelatedI have a create a report for our dept with certain criteria. So far what I need is a report that shows last weeks numbers or sign ups. I can't get the date search or between to work.
What I need is one for month end and one for last 7 days.
here's what I have so far.
select ap.name
to_char(ap.opendate,'MM-DD-YY') "Open Date"

I have one table for eg. TB_Fruits.
In that i have one column FruitsName(Varchar)
In that column i am storing string in comma separated values.
Select FruitsName from tb_fruits;
Result: orange,banana,apple
Now the issue is suppose if i try to insert any of these fruits name again then it should not allow me to insert.
Suppose now if i try to insert ('grapes,banana')
or
('apple,grapes')
the orange,banana,apple can be in any position.
How to check if any of these names already exist or not in the column fruitsname?
I cannot use like or INstr function here. because the position is not fixed not even string.
in one of the data base some of the column values are TE. i wanted to serch in what are the tables this TE values are present. so m running the below function
CREATE OR REPLACE FUNCTION find_in_schema(val VARCHAR2)
RETURN VARCHAR2 IS
v_old_table user_tab_columns.table_name%TYPE;
v_where VARCHAR2(4000);
v_first_col BOOLEAN := TRUE;
[code]....
but v_where := v_where || ' or ' || r.column_name || ' like ''%' || val || '%''' is giving me numaric or value error when i run as select find_in_schema('@TL') from dual; so how can i go ahed with the serch ?
