Parameters in view query

I'd like to create a view such this:
select ivw.a
from (
select ta.a
from table_a ta
where ta.c = :1
) ivw
How should I create the view object, and how should I pass the paramerers for it?
I tried to use the setWhereClauseParam method of oracle.jbo.RowSet, but it affects to the view object's where clause.
Thanks in advance,
Gábor Tóth

This is some nice functionality the BC4J team might want to implement.
I created the view on the db and then created a EO based on the view. The view is then based on the EO.
You can decide not to base it on an EO.

VIEW Query Problem

Hi Greg,
I had created a view on a table which doesn't have Primary Key, but it has Unique and Not Null constraints on required columns.
I had wrote a procedure to query the data on VIEW. I have experienced strange problem, very first call to procedure will take more time than succeeding requests. For example from second request onwards, it returns data in < 2 Sec, but first transaction is taking 12 Sec to 30 Sec.
I thought that very first time VIEW is taking time to refresh it self. So, I added FORCE keyword in CREATE VIEW stattement. However, that doesn't helped out.
In my further investigation I came to know that base table on which VIEW created, has to be loaded in to memory before querying on VIEW.
So, I had executed a simple select statement on base table, before I execute VIEW query in procedure.
With this change I got results consistently < 2 Sec all the times.
My question is instead of executing the select statement on base table is there a way to load base tables data in memory before querying on VIEW?
Thanks,
Subbarao

Hi,
A view is nothing but parsed SQL statements stored in the database, a view may or may not run faster. If you execute the SQL used to define the view how much time is it taking. If you want try looking at MATERIALIZED VIEW , that may help you.
thanks

create or replace procedure temp (

Spatial vs. materialized views/query rewrite

Dear all,
we are trying to use Spatial (Locator) functionality together with performance optimization using materialized views and query rewrite, and it does not seem to work. Does anybody has experience with this?
The problem in more detail:
* There is a spatial attribut (vom Typ GEOMETRY) in our table;
* we define a materialized view on that table;
* we run a query that could be better answered using the materialized view with query rewrite;
*the optimizer does not choose the plan using the materialized view, query rewrite does not take place;
This happenes, even if neither the materialized view, nor the query contains the spatial attribut.
The explanation given by the procedure DBMS_MVIEW.Explain_Rewrite is:
"QSM-01064 query has a fixed table or view Cause: Query
rewrite is not allowed if query references any fixed tables or views"
We are using Oracle 9R2, Enterprise Edition, with locator. Nevertheless, it would also be interesting, if there is any improvement in 10g?
A more complicated task, using materialized views to optimize spatial operations (e.g., sdo_relate) would also be very interesting, as spatial joins are very expensive operations.
Thanks in advance for any comments, ideas!

Cause: There doesn't exist any materialized view that can be used to rewrite this query.

i.e. query rewrite does not work!
If this works, the next issue is to use materialized views for optimizing spatial operations, e.g., a spatial join. I can supply you with an example, if necessary (only makes sense, I think, after the first problem is solved).
Thanks in advance for any ideas, comments!

Creating a Hierarchy Viewer query

Hello,
I'm having huge difficulties creating a Hierarchy Viewer Query. I've looked through the source code contained withing the demo, but it seems to require great knowledge regarding the component. I'm using a three-node model, each node grouped within it's parent.
So I created a custom View to be used as a result list for the query and this part is working just fine. I can pick the unique ID for the node I want from the search results when the user selects one, but I don't know how I can make that specific node my "anchor", my "current node", after that.
Since I'm looking for a specific "contact_id" selected from the search results, I think the correct way of doing it is finding it's node on the TreeModel, and then setting it as my current anchor.
Please, any tips, directions or suggestions on how can I go about doing this?
Thanks!!

Hi!
Thanks for the attention, but I've been through all the basic stuff. The HV documentation only teaches the most primitive part of it. I searched all blogs related to HV, all articles I could find, I've meddled with the demo source code and all I can think of, but I couldn't find anyone who would give much insight on the mechanics of the component or how to build a really powerful search engine for it.
As a sugestion for the developer team, it would be great if the query for this component allowed us to specify actions to be performed on all levels of the tree, instead of only the root node, since most of the time people use HV as a multi-root tree.

Does XML approach for passing parameters in the query make the query slow?

Hi,
I am using XML approach for passing parameters in a query. This is running very slow but when I pass comma separated values in parameter, it runs very fast.
So it concludes that we should not use XML approach for passing parameters. Please confirm me that Am I right or wrong?
I have also googled to clear my doubt but not get solution till now. please help me.

Sachin

Defining more parameters than a query needs

Hi.
When I run the following code, I get the error "ORA-01036: illegal variable name/number" .
The problem is that I currently define more parameters than the query needs. Thats because I don't know how many bind variables the query uses, and I would not like to parse the query ...
I don't understand why I have to define exactly the same number of parameters, and in the exact order ... It doesn't make sense. As bind variables have names, there should be no problem passing more parameters or parameters in a different order: the binding should be done by name...
I'm currently using Oracle10g, ODP.NET and .NET Framework 2.0.
I would appreciate any help ...
Thank you.

Hi,
BindByPosition is the default behavior as per the docs, and you can change that by setting cmd.BindByName=true which adds a little bit of extra overhead.
That wont fix the error seen when binding a random number of parameters to the statement though. You need to bind the correct number and types of parameters.

Passing parameters to select query in DB link from invoke...

I am having a DB partner link which executes the select query based on user specified parameter.
Now i have created an invoke activity and specified input[this needs to be passed to query] and output parameters[this is query result]. This invoke activity calls DB partner link in which one parameter has been created to be used in select query. So my doubt is , will DB partner link take up the input parameter of invoke activity automatically or do we need to specify any mapping for this?

When you create a db partnerlink the parameter you create for your select is the input and when you create the input variable in the invoke for this partnerlink it is created with the right type for the parameter.
Create an Assign before your invoke and assign a value to the input variable you created in the invoke. That value will be passed and used as the parameter in the select.
Heidi.

How to make Multiple parameters to sql query string seperated by ,(comma) ..

Hi,
I would like to konw how I can make multiple parameters to sql query string seperated by ,(comma) ..
For example, this parameters can be printed like 'abc,dde,ggf,eeg' ,once I use "join(Parameters!rpCode.Value,",")" with report builder ,
By the way, when I test this multiple parameters by Query Designer of report builder there was no problem,.(using Define query parameters, I put abc,dde,ggf,eeg)
however, when I run this report , it won't be executing , with (rsErrorExecutingCommand)
Plz, help me....

If its sql query then it should like this
Select t.*
from table t
inner join dbo.ParseValues(@Parameters,',')f
on f.val = t.ID
ParseValues can be found him
http://visakhm.blogspot.in/2010/02/parsing-delimited-string.html
or easier way is
Select t.*
from table t
where ',' + @Parameters + ',' LIKE '%,' + CAST(t.ID AS varchar(10)) + ',%'

Declaratively set the value of a bind parameter in a view query

Can I declaratively set that I want the value of the bind parameter in the view query to be the value of a specific field in the current row of a specific iterator in my data bindings? Thanks :D

Hm I guess I should mention I'm doing the retrieval in Java, using a ValueChangeListenerIn this case, you will still need to bind an ExecuteWithParams action to your page definition and execute it from your ValueChangeListener after supplying its named data.
In the code spinet, the new value from the ValueChangeEvent is passed to the bind variable.
public void yourValidChangeListener(ValueChangeEvent valueChangeEvent) {
    // get the ExecuteWithParameters operation binding from the bindings
    OperationBinding executeWithParameters = ADFUtils.findOperation("yourExecuteWithParametersBindingId");
    // setup bind variable using the new value from the valueChangeEvent
    executeWithParameters.getParamsMap().put("yourParameterId", valueChangeEvent.getNewValue());
    // execute
    executeWithParameters.execute();
    // check for errors
    if(executeWithParameters.getErrors().size() != 0) {
        // error(s) occured
}

How to pass runtime parameters to Oracle Query from xMII server

Please can anybody help me that how to pass runtime parameter to Orcle Query from xMII server.

It works the same way as I described in this thread [How to pass runtime parameters to MySQL Query from xMII server]. It does not matter the datasource MII will work the same for all queries, at least for passing in parameters. How to write those queries and their datatypes will be the differences.

The answer is the same as for your other thread. The mechanism is the same regardless of the end database. The SQL syntax will be different for each database vendor depending upon which functions you are invoking. The main areas of difference between SQL Server, Oracle, DB2, etc. deal with dates (times also) and strings, but there are others as well.
