Connecting grid to view\query

I need some tutorial sample project explaining how to connect a grid to view\query from a DB. I failed to google it - any links?

The grid is called JTable.

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

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!
Cheers,
Gergely Lukacs

Hi Dan,
thanks for your rapid response!
A simple example is:
alter session set query_rewrite_integrity=trusted;
alter session set query_rewrite_enabled=true;
set serveroutput on;

END LOOP;
END;
The message you get is:

i.e. query rewrite works!

ALTER TABLE TESTTABLE

FOR i IN 1..Rewrite_Array.count
LOOP
DBMS_OUTPUT.PUT_LINE(Rewrite_Array(i).message);
END LOOP;
END;
The messages you get are:
QSM-01064 query has a fixed table or view
Cause: Query rewrite is not allowed if query references any fixed tables or views.
Action: No action required.
QSM-01019 no suitable materialized view found to rewrite this query
Cause: There doesn't exist any materialized view that can be used to rewrite this query.
Action: Consider creating a new materialized view.
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!

Crystal reports 2013 , SAP MDX Driver not able to connect with BW BEX Query

Hi All,
We just installed Crystal 2013, and want to create crystal report on SAP BW CUBE/BEX Query through SAP MDX Driver.
1.When start connecting through SAP MDX Query option from new connection , SAP Systems which are in SAPLOGON are not appearing in initial screen. where as from OLAP Connection we are able to connect to SAP BEX Query.
2.Even from SAP Tool kit we are not able to connect to BEX query, we are getting ERROR MESSAGE.
and we are using SAP BI BO PLATFORM 4.1 sp01 .
Please suggest me , if I am missing any configuration settings.
Regards,
Joseph

Hi Joseph,
Before you start building the report, make sure the right transports have been loaded on the SAP System. The right Transport files are the ones found inside the installation zip you download from SAP's server. They're under the "Collaterals\Add-Ons\SAP\Transports" folder.
For more info on Transports, authorizations etc, please have your BASIS admin go through this wiki:
Crystal Reports 2008 and BW - Installation and Configuration - Business Intelligence (BusinessObjects) - SCN Wiki
To resolve your first issue, please follow the steps from this thread:
Problems with SAPLogon.ini for SAP GUI and Crystal 2011
P.S: Crystal Reports for Enterprise 4.1 does a better job at handling BEx queries that the CR 2013 designer. It directly connects to BEx queries via the BICS connectivity driver and doesn't need the Transports to be there on the SAP System. You might want to give this flavour of CR a try too.

Save Query - An error occurred while creating connection strings for the query

A workbook trying to edit and reload I get the following error "Save Query - An error occurred while creating connection strings for the query" No Power Pivot data model or anything.

I am getting the same error when editing a Power Query in an Excel spreadsheet. It happens when I change a Group By step to do a Sum instead of Count Rows.

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.

Materialized view query (Oracle 9i)

Hi,
Does a table named profit_mvw already exist?
The following example illustrates the two steps required to register a user-defined table. First, the table is created, then the materialized view is defined using exactly the same name as the table. This materialized view sum_sales_tab is eligible for use in query rewrite.
CREATE TABLE sum_sales_tab
PCTFREE 0 TABLESPACE demo
STORAGE (INITIAL 16k NEXT 16k PCTINCREASE 0) AS
SELECT s.prod_id, SUM(amount_sold) AS dollar_sales,
SUM(quantity_sold) AS unit_sales
FROM sales s GROUP BY s.prod_id;
CREATE MATERIALIZED VIEW sum_sales_tab
ON PREBUILT TABLE WITHOUT REDUCED PRECISION
ENABLE QUERY REWRITE AS
SELECT s.prod_id, SUM(amount_sold) AS dollar_sales,
SUM(quantity_sold) AS unit_sales
FROM sales s GROUP BY s.prod_id;

How do I remove the grid in view permanently??

I can't remove the grid in view of CS5. It comes up on every photo I open though I uncheckk it it each time. How do I

Usually if you open an image into photoshop, turn off the grid and then close photoshop, that will keep the grid off.
Close photoshop by using File>Exit or Photoshop>Quit Photoshop

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

Thank you for your help

Hi,
i m answer my self about this question
it is possible to use a extraction file generated by S2 system in S1 system to query directely this file and we can also to use this file by view query transaction
