Is it possible to create views with parameters ?

Hi,
As MS-Access, is it possible to create views with parameters ?
Ms-Access syntax : parameters [a] text; select * from table where code = [a]
If yes, can you give samples ?
Regards
Pascal

I suggest you you write a stored procedure that returns a recordset in oracle. Then execute the stored procedure and loop through the record set.
Look in in MS Knowledgebase searching on ADO Stored Proceedures for the VB/C++/VBS .. code.
Look in in Oracle PL/SQL guide for the Stored Proceedure code.

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. :-)

Encapsulating a query in a view with "parameters"

I have a complex query using analytic functions and an inline view, something like:
select * from (
select a, b, c, row_number() over (partition by x, order by y) rn
where b like 'XXX%'
where rn = 1;
(The actual query is a little more complex, but that's the idea). This query performs very well.
As the query is of some general use, I'd like to package it up. However, the 'XXX%' pattern will vary with each use.
If I try to make a view v which is the query minus the XXX% where clause, the optimiser cannot merge the where clause and the view in a query like
select * from v where b like 'XXX%'
This doesn't surprise me too much - merging like that is going to be hard (if indeed it's possible at all!) As a result, the query using the view is significantly slower.
Is there any way of making my original query reusable? For PL/SQL, I can use a function returning a REF CURSOR and taking the pattern as a parameter - but I need to use this from SQL.
I could write a pipelined function and then do select * from table(my_fn('XXX%')). However, this is in 8i, where I don't have that option. Also, for a pipelined function, I'd need to define a record type and an associated table type - what seems like quite a lot of code for what is conceptually pretty simple.
Have I missed any obvious options? I can live with the pipelined function and "no way until 9i" - but only as a general answer. For my current specific issue, that's equivalent to "you can't do this".
I thought of using SYS_CONTEXT, but if I understand correctly, I can only use that in PL/SQL, as I can't set the context outside of an authorised package. Is that right, or is there a way I could use contexts? (Hmm, I need to be able to use the query from SQ, but I could probably execute a PL/SQL procedure before running the query, to set things up - does that help?)
Thanks for any suggestions.
Paul.

SYS_CONTEXT would work, as would package global variables.
I once wrote an example about this (though with TABLE function but for your case the principle stays the same) which you may find here:
Re: TABLE FUNCTION - Using database view - send parameters to the function.

View with parameters

Hello,
Can we create the view with the parameters? How to do that? We need to create the sql script with parameter for super user to query, instead of create sql script then we would like to create the view then user can select only view.
Many thanks in advance. :-)

Hi,
Views using SYS_CONTEXT, as Justin mentioned, are perhaps the most common way to simulate parameterized views in Oracle.
Another method is to use a table (usually a Global Temporary Table) to hold the parameters. The view can then join to the table, use it in scalar sub-queries, IN-sub-queries, etc.
This is the best way if you need to use the same parameterized view two (or more) times in the same query, with different parameters each time.

How to create view with schemabinding on cross datbases(partitioned views)

Hello Everyone,
Please help me to sort this issue. I know it is not possible bind the scheman in below example. But is there any solution to solve this issue.
I've tables like below
create database D1--First database
create table dbo.t1(
id int
create database D2--Second database
create table dbo.t2(
id int
i want to create a view with the schema binding option on this
create database D3
use d3
create view vw_v1
with schemabinding
as
select id from d1.dbo.t1
union all
select id from d2.dbo.t2
I'm getting this below error
Msg 4512, Level 16, State 3, Procedure vw_v1, Line 7
Cannot schema bind view 'vw_v1' because name 'd1.dbo.t12' is invalid for schema binding. Names must be in two-part format and an object cannot reference itself.
Many thanks

CREATE VIEW
SCHEMABINDING
Binds the view to the schema of the underlying table or tables. When SCHEMABINDING is specified, the base table or tables cannot be modified in a way that would affect the view definition. The view definition itself must first be modified or dropped to remove
dependencies on the table that is to be modified.
> When you use SCHEMABINDING,
the select_statement must include the two-part names (schema.object)
of tables, views, or user-defined functions that are referenced.

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.

Creating Views with DI APIs DoQuery-Method in SQL 2005

Hi @All,
I've had the following (solved) problem:
The DB installer of one of our AddOns is also creating a bunsh of views for our UDTs. The installer always executes the following two statements for each view:
IF OBJECT_ID ('[dbo].[@NSP_EXAMPLE_VIEW]', 'V' ) IS NOT NULL
    DROP VIEW [dbo].[@NSP_EXAMPLE_VIEW];
CREATE VIEW [dbo].[@NSP_EXAMPLE_VIEW] AS
SELECT
     T0.U_Field3,
     T1.U_Field1,
FROM
     [dbo].[@NSP_A] T0 INNER JOIN
     [dbo].[@NSP_B] T1 ON
     T0.U_Key=T1.U_Key AND
     T0.U_CostNo=T1.U_CostNo;
This has worked fine for the first 3 views we need. Then came the 4th view and we get an exception from the doQuery. I had to change the SQL-2005 compatibility level back to 80 to create the 4th view because of an incompatible "FOR BROWSE"-statement.
When it was created under level 80 I saw the problem: ONLY the 4th view was extended with the "FOR BROWSE"-Statement by DI-API. I didn't see any difference in the 4th VIEW-statement which could be the reason that only this one gets the "FOR BROWSE"
Anyway! Big thanks to John Mackin and the users of this thread:
[Formatted search;
Adding an SQL-comment "--FOR BROWSE" at the end of the VIEW-creation statement has solved the problem.
(I hope the DI-API query parser will not change this behaviour in the future :-o )
Cheers,
Roland

Thanks for the replies, but casting gave me the original 'General Error' as well.
I tried to make a stored procedure out of it. I used this page as a guide:
http://www.davidhayden.com/blog/dave/archive/2005/12/30/2652.aspx
The stored procedure looks like this:
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go
CREATE PROCEDURE [dbo].[TestItems]
    @PageIndex INT,
    @PageSize INT
AS
BEGIN
WITH tmpItems AS (
SELECT ROW_NUMBER() OVER (ORDER BY ItemCode DESC)AS Row, ItemCode, ItemName
FROM OITM)
SELECT ItemCode, ItemName
FROM tmpItems
WHERE Row between (@PageIndex - 1) * @PageSize + 1 and @PageIndex*@PageSize
END
I am able to call this stored procedure like this:
exec TestItems 10, 10 -- (returns item 91 to 100).
This solution meets my immediate requirements, but I don't like the fact that I added the stored procedure to the administration itself. Is it possible to add the stored procedure to a different database and still use the DI server?
Thanks for your time!

What is the use for CREATING VIEW WITH CHECK OPTION?

Dear Legends,
I have a doubt
What is the use for creating view?
A: First Data Integrity, Selecting Particular Columns..
What is the use for creating a view with check option?
A: As per oracle manual I read that its a referential integrity check through views.
A: Enforcing constraints at DB level.
A: using CHECK OPTION we can do INSERTS UPDATES for a view for those columns who have no constraints... is it right??
A: If we do a INSERT OR UPDATE for columns who have constraints it will show error... is it right???
Please clear my doubt's Legends
Lots of Thanks....

Hi, Karthick,
karthiksingh_dba wrote:
... What is the use for creating view?
A: First Data Integrity, Selecting Particular Columns..Most views are created and used for convenience. A view is a saved query. If the same operations are often done, then it can be very convenient to code those operations once, in a view, and refer to the view rather than explicitly doing those operations.
Sometimes, views are created and used for security reasons. For example, you many want to allow some users to see only certain rows or certain columns of a table.
Views are necessary for INSTEAD OF triggers.
What is the use for creating a view with check option?
A: As per oracle manual I read that its a referential integrity check through views.The reason is integrity, not necessarily referential integrity. The CHECK option applies only when DML is done through the view. It prohibits certain changes. For example, if a user can't see certain rows through a view, the CHECK option keeps the user from creating such rows.
A: Enforcing constraints at DB level.I'm not sure what you mean. Please give an example.
A: using CHECK OPTION we can do INSERTS UPDATES for a view for those columns who have no constraints... is it right??No. Using CHECK OPTION, you can do some inserts and updates, but not others. The columns involved may or may not have constraints in either case.
A: If we do a INSERT OR UPDATE for columns who have constraints it will show error... is it right???If you try to violate a constraint, you'll get an error. That happens in views with or without the CHECK OPTION, and also in tables.
