Create a view with parameter

it's posible create a view with parameters?
i want to create a view and pass it parameters, in the same way when i create a procedure or function.
i never have seen it, but i would like to know if that's posible
thanks

You cannot create a view with parameters. The only way is to use a stored proc to dynamically create the sql statement. The substitution variable approach does not work. SQL*Plus will prompt for the value of the variable at compile time (i.e. when you create the view) and use the value you provide in the view's query.
SQL> create or replace view jws_test_v as
2 select * from jws_test where flag = '&flg'
3 /
Enter value for flg: AA
old 2: select * from jws_test where flag = '&flg'
new 2: select * from jws_test where flag = 'AA'
View created.
SQL> select * from jws_test_v
2 /
no rows selected
SQL> select text from user_views where view_name = 'JWS_TEST_V'
2 /
TEXT
select "LEV1","LEV2","LEV3","LEV4","LEV5","LEV6","FC","FLAG","ONAFT","ONAPT","CU
PEFT","CUPEPT" from jws_test where flag = 'AA'This makes sense, since substitution vartiables are a sqlplus construct, not a sql or Oracle construct. A view constructed in this way would not be callable from anywhere other than sqlplus.

No.AFAIK, there's nothing called as "parameterized MV".
Materialized View store data like tables (and not like Views). So, does it make sense when you say - "table with parameters" ?
Could you please explain your business requirement?
What is the purpose behind those 2 parameters?

Is it possible to create a spatial view with paramete?

Is it possible to create a view with parameter like following:
SELECT GEOM FROM INTERSTATES WHERE MDSYS.SDO_FILTER(GEOM, MDSYS.SDO_GEOMETRY(2003, 8307, NULL, MDSYS.SDO_ELEM_INFO_ARRAY(1, 1003, 3), MDSYS.SDO_ORDINATE_ARRAY(?, ?, ?, ?)), 'querytype=WINDOW') = 'TRUE'
so that I can specify ???? at run time.
If not, is there a way to create a view that perform variable window query?

You may want to look at application contexts, that way you may have code something like this:
create or replace context gis_ctx using gis_params ;
create or replace package gis_params
as
procedure set_bounds( minx in number, miny in number, maxx in number,maxy in number );
end;
create or replace package body gis_params
as
procedure set_bounds( minx in number, miny in number, maxx in number,maxy in number )
is
begin
dbms_session.set_context( 'gis_ctx', 'minx', minx);
dbms_session.set_context( 'gis_ctx', 'miny', miny);
dbms_session.set_context( 'gis_ctx', 'maxx', maxx);
dbms_session.set_context( 'gis_ctx', 'maxy', maxy);
end ;
end ;
To use this method you´ll have to execute
gis_params.set_bounds(-3,40,-2.9,40.1) ;
before doing the select.
SELECT GEOM
FROM INTERSTATES
WHERE MDSYS.SDO_FILTER(GEOM,
MDSYS.SDO_GEOMETRY(2003,
8307,
NULL,
MDSYS.SDO_ELEM_INFO_ARRAY(1, 1003, 3),
MDSYS.SDO_ORDINATE_ARRAY(sys_context ('gis_ctx', 'minx'),
sys_context ('gis_ctx', 'miny'),
sys_context ('gis_ctx', 'maxx'),
sys_context ('gis_ctx', 'maxy'))),
'querytype=WINDOW') = 'TRUE' ;
I f you are in a web environment, read about GLOBAL CONTEXT ACCESSED GLOBALLY .

How can i create a view with jdevlopper 10132

hi,
i want to know how to create a view with JDeveloper 10132.
thanks

Sorry, but I had to jump in here.
7rouz - you've certainly violated the 10 commandments for posting here...
Do you want to:
1). Create a database view directly in the database
2). Model a database view using the database modeller
3). Create an ADF BC View Object
4). Create some type of visual object (web page, Swing panel)
5). something else.
Your question is too ambiguous to yield an answer, unless by luck.

Need help in creating a view with Encryption for hiding the code used by the multiple users

Hi,
Can anyone help me out in creating view with encryption data to hide the stored procedure logic with other users.
I have create a stored procedure with encryted view but while running this manually temporary views are getting created, therefore the problem is if there are 500 entries then 500 temp views will get created.
Any solution to aviod creating temporary views, please refer my code below
USE [etl_validation]
GO
/****** Object: StoredProcedure [dbo].[Pr_DBAccess_mod]    Script Date: 05/23/2014 12:53:22 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[Pr_DBAccess_mod](@ETL_CONFIG_ID INT)
AS
BEGIN
DECLARE @openquery NVARCHAR(MAX),
@DATABASENAME NVARCHAR(100),
@HIERNAME NVARCHAR(100),
@TABLENAME NVARCHAR(100),
@SERVERTYPE NVARCHAR(100),
@SERVERNAME NVARCHAR(100),
@USERNAME NVARCHAR(100),
@PASSWORD NVARCHAR(100),
@ETL_CONFIG_IDN NVARCHAR(100);
SET @ETL_CONFIG_IDN=CAST(@ETL_CONFIG_ID AS NVARCHAR);
SET @TABLENAME='Department';
SET @SERVERTYPE='SQL';
SET @SERVERNAME ='192.168.31.176';
SET @DATABASENAME='AdventureWorks2008R2';
SET @HIERNAME = 'HumanResources';
IF @SERVERTYPE='SQL'
BEGIN
/*SET @openquery= 'SELECT * INTO ##TestTable
                 FROM OPENROWSET(''SQLNCLI'',''server=192.168.31.176;Trusted_Connection=yes;'','''+@query+''')'
SET @openquery= 'CREATE VIEW '+@TABLENAME+@ETL_CONFIG_IDN+
                 ' WITH ENCRYPTION AS SELECT * FROM OPENROWSET(''SQLNCLI'',''SERVER='+@SERVERNAME+';TRUSTED_CONNECTION=YES;'',''SELECT * FROM '+@DATABASENAME+'.'+@HIERNAME+'.'+@TABLENAME+''')'
SELECT @openquery
END
EXECUTE sp_executesql @openquery
END

Hi aa_rif,
According to your description and code message, you execute the sp_executesql statement in your stored procedure, it indeed create many views with a tablename and ETL_CONFIG_ID named. If you need not to use these temporary views, you can delete them when
it contains the tablename in one view name.
In addition, if you want to create view with encryption in SQL Server, you can use directly the ENCRYPTION option to encrypt the T-SQL of a view in create view commands, for more information, see:
http://learnsqlserver.in/4/Create-View-With-Encryption.aspx. if not, you can descript more detail about requriements, so that more forum members can involve into the thread and help you
out.

How to create a view with a column of counts of the occurence of values

I want to create a view with the following result:
ID   COUNT
1     1

3     2
5     3
How would I accomplish this?

Sorry, my mistake. I was thinking about counting distinct events.
I created a table with your example values:
You should do a projection with a calculated column = 1:
And then add this calculated column as an aggregated measure on the aggregation node:

How to create a view with parameters; read the documentation but nothing!

Hello!
I'm new to the Oracle world but together with my coworkers we need to very quickly study Oracle to figure out whether we'll add Oracle to our list of supported databases or not.
Question: How do I create a view with parameters?
I've read the documentation but I could not find this! I found the sql syntax to create a view but no parameters whatsoever...
I have found on the web some very complicated way of doing this, but doesn't Oracle support Views with parameters?
The goal here is to return a recordset, don't forget, so,please don't speak about stored procedures unless you are going to tell me how to get a recordset out of a stored procedure! ;)
Thanks for all your help and attention!
Jorge C.

You can set up a parameterized view via context as follows:
1. Set up a procedure to set your context values:
create or replace procedure p_set_context (p_context IN VARCHAR2,p_param_name IN VARCHAR2,p_value IN VARCHAR2)
as
BEGIN
sys.dbms_session.set_context(p_context,p_param_name,p_value);
END;
2. Create your context using the procedure you just created
create or replace context my_ctx using p_set_context
3. This is the test table I'll use
create table my_table(col1 number)
and populate it:
begin
for v_index in 1..10
loop
insert into my_table values(v_index);
end loop;
end;
and the view that will be parameterised
create or replace view v_my_table as select col1 from my_table where col1 between sys_context('my_ctx','start_range') and sys_context('my_ctx','end_range')
4. Now set the parameters using the procedure above.
begin
p_set_context('my_ctx','start_range','1');
p_set_context('my_ctx','end_range','5');
end;
5. Selecting from my_table will give you 1 to 10 (no surprise there :-) )
selectng from v_my_table will give you 1 to 5
You can use the context to set formats etc using the same principle. A common gotcha to watch for is trying to set the context directly using DBMS_SESSION.SET_CONTEXT instead of creating a procedure. This belongs to SYS and SYS won't have the privileges to set your context so you get an insufficient privileges result leading to much headscratching and unnecessary grants (at least that's my understanding of it).
Sorry Jorge, as you're new to Oracle I should also have pointed out for completeness sake, that you can change the parameters at any time through recalling the p_set_context, for example, following on from above, after your "select * from v_my_table" and seeing 1 to 5, you could then do
begin
p_set_context('my_ctx','start_range','3');
end;
and when you requery 'Select * from v_my_table' you will now see rows 3 to 5.
Bit of a simplistic example, but you can see how easy it is. :-)

Create a View with Aggregation Function (COUNT)

I've been looking up and down for a way to create a view with a few basic fields and some other fields containing aggregation function.
For instance:
To display a view that contain all the Contract Agreement and the corresponding count of the PO releases.
Agreement Nbr, Total PO releases
I need this view so that I can create a search help with this view.
I found something about the "CREATE VIEW" statement, but I don't have any idea how to use it.
Any helps toward this matter is very much appreciated, thanks.

Hello Aldern
I guess you have read about the SQL statement "CREATE VIEW". When we create a view in the dictionary this SQL statement is finally called to create the view on the DB. Thus, since we do not have any aggregation options in views you cannot achieve what you want using views.
The solution for your problem is to create a <b>search help</b> having a <b>search help exit</b>. Within the exit you can do your aggregation functions and add these values to the displayed search help data.
Regards
Uwe

Creating a view with a primary key

I want to create a view with a defined primary key. I understand
the view is created within a select statement, but do not
understand how you would define a particular field as a primary
key in the view. Also if your select statement attempts to build
the view and has duplicate keys in the select result set, what
would happen when the duplicate key is found? Would it just not
include the duplicate key in the view?
Thanks in advance for your help.

I have a rather difficult problem with duplicate invoice numbers
contained in unique records. In other words I have many records
that appear as follows:
3593, 0004009090, CUSTOMER, TAX, 20000117,014011976-01
4411, 0004009090, CUSTOMER, TAX, 20000718,014011976-01
The last field is invoice number '014011976-01' In my case I am
building a flat file using UTL_FILE for loading into SAP
Business Warehouse. In SAP I need to have Invoice number as a
key in which case I can't have duplicate invoice numbers. All
the SQL I have tried to date returns a large amount of records
similar to the above records. I am selecting these records from
4 different schemas which represent 4 different companies. I
realize the data is the problem and that the vendor of the
product I am working with should not allow records with
duplicate invoice numbers, but I have to get the data loaded as
that is what they want and are paying for. So back to my View. I
was hoping to create a view and be able to work in the view to
remove duplicate records prior to writing them to a file. Any
suggestions are welcomed.
Thanks

Cannot create view with parameter bindings

Hi, I'm trying to create this view in SQLPlus:
SELECT order_no, SUM(cut_qty),
SUM(received_qty)
FROM (
SELECT order_no, cut.dated, DECODE(cut.bimetallic, 'F', cut.quantity, cut.quantity/2) cut_qty,0 AS received_qty
FROM cut_shop_orders_dated cut
WHERE cut.dated BETWEEN TO_DATE('&date1','DD/MM/YYYY') AND TO_DATE('&date2','DD/MM/YYYY')
UNION
(SELECT order_no, rec.dated, 0, rec.quantity
FROM received_shop_orders_dated rec
WHERE rec.dated BETWEEN TO_DATE('&date3','DD/MM/YYYY') AND TO_DATE('&date4','DD/MM/YYYY')))
GROUP BY order_no
The problem is that sqlplus asks me for the parameter values and then creates it with these values as literal dates in the to_date function, those not asking for parameter values in runtime.
How can I create it using parameters with no values at design time?
Thanks.
Leandro.

if you want something like :
select * from emp $where_clause;
you can write a procedure with parameter and run it as dynamic sql for example
create or replace procedure pr1 ( p_where varchar2) is
begin
execute immediate 'create or replace view view_name as select * from emp '|| p_where;
end pr1;
/then run it on sql*plus
SQL> exec pr1('where deptno = 10');
make sure you give yourself "create any view" rights explicitly.

Thanks,Create a pivot table and put "milestone_name" in the Columns section under the Labels.
Put "actual_end_date" in the Measures section and change the Aggregation Rule to "Max."
The rest of the attributes keep in Rows section.
