Rewrite of the query

Oracle Database 11 g Enterprise Edition Release 11.2.0.2.0 - 64 bit Production version

Hello

I want to rewrite a query in a PL/SQL function that I inherited, which returns a list of e-mail addresses to send a notification by e-mail to.

The function as it is currently written is:

DECLARE
    reporttype  NUMBER;
    count1      NUMBER;
    count2      NUMBER;
    email_addr  VARCHAR( 255 );
BEGIN

    SELECT COUNT( * )
    INTO   count1
    FROM   project_report_type
    WHERE  project_id = :P51_PROJ_ID AND
           type_id IN (SELECT type_id FROM report_type);

    IF (count1 != 0) THEN
        SELECT COUNT( * )
        INTO   count2
        FROM   report_admin
        WHERE  type_id IN (SELECT type_id FROM report_type);

        IF (count2 != 0) THEN
            SELECT listagg(TO_CHAR(resources.resource_email), ', ') WITHIN GROUP (ORDER BY resources.resource_email)
            INTO   email_addr
            FROM   report_admin
            LEFT JOIN resources ON resources.resource_onepass_id = report_admin.user_onepass_id
            WHERE  report_admin.type_id IN (SELECT project_report_type.type_id
                                            FROM   project_report_type
                                            WHERE  project_report_type.project_id = :P51_PROJ_ID AND
                                            project_report_type.type_id IN (SELECT report_type.type_id FROM report_type)
                                           );

            RETURN email_addr;
        END IF;
    END IF;
END;

I'm sure this can be written much more effectively, but I don't know how.

The first charge is to determine if a record exists in the table PROJECT_REPORT_TYPE for the project from the front end page and the PROJECT_REPORT_TYPE. TYPE_ID exists in the REPORT_TYPE table.

If at least one record exists then determine if a record exists in the REPORT_ADMIN table where the REPORT_ADMIN TYPE_ID exists in the REPORT_TYPE table.

If there is at least one record of that result, then create a list of e-mail addresses of RESOURCE table join again on the table REPORT_ADMIN, where REPORT_ADMIN TYPE_ID exists in the PROJECT_REPORT_TYPE table.

I thought of two queries that don't COUNT (*) I could join these two tables together for the values of the query online, SELECT type_id FROM report_type, is a glance toward the top of the table. Therefore, values for TYPE_ID columns must come from the REPORT_TYPE table.

So, I thought that maybe:

SELECT count (*) FROM project_report_type INNER JOIN report_admin count1 ON project_report_type.type_id = report_admin.type_id WHERE project_report_type.project_id =: P51_PROJ_ID;

If I had all the records in this query, then get a list of e-mail addresses?

Can what information I provide?

Thank you

Joe

Hi, Joe,

It depends on what you want to do when no line is detected.

If you want that the function returns NULL if no line is detected, then simply:

Email_address RETURN;

If you want the function to return a fixed string, then you can do something like

RETURN NVL (email_address, '(aucune donnée trouvée) ");

Just what you want, you must execute a RETURN statement, so it would be unwise to put the RETURN statement in an IF block.

Impossible to activate the rewrite of the query, no error

Hello
I created a simple MV with activated query rewrite, and it works well. The MV is very simple:
Mv_sales CREATE MATERIALIZED VIEW
NOLOGGING
REFRESH THE STRENGTH TO DEMAND
ACTIVATE THE QUERY REWRITING
AS
SELECT
s.cust_id,
Sum (s.QUANTITY_SOLD) sold_qty,
Sum (s.AMOUNT_SOLD) sold_amt
S SALES
GROUP BY s.cust_id
;
I tested the mechanism of query rewriting, and everything works as expected.
Now, I created an another MV with a motion very similar to the one above, but with several tables.
An excerpt from the new query:

AND WSF. DIM_SALE_DATE_KEY = DD. DIM_DATE_KEY
GROUP BY

I can create the MV, but the query rewriting will not activate!
If I execute ALTER materialized view mv_test ALLOW to REWRITE the QUERY. It runs without giving me an error, but the MV is not always activate the rewrite of the query.
Am I missing something? Can we not have Query Rewrite on a MV with several tables in the query?

Kind regards.

How we force a query to use transparently a hint, even if the index is not given in the query as a query rewriting.

How we force a query to use transparently a hint, even if the index is not given in the query as a query rewriting.
For example:
If the user runs a query select deptno, avg (sal) from emp group by deptno;
We want the optimizer to use a hint of result_cache with this request, and it should be transparent to the user.
Query should be rewritten to seamlessly
Select / * + result_cache * / deptno, avg (sal)
WCP
Group of deptno;
How can this feature we make? Please advice.
I checked the possibility of SPM and contours, but it is not clear if this rewrite is possible here.

Top query runs too slowly on the real data set. Is there an effective way to rewrite the query which can perform the dough?
Any help or suggestion would be appreciated
Thanks in advance

At the time where the application may not throw anything until after he has retrieved and grouped all the ranks of zone_view. His estimate of 7.5 minutes to scan millions 639 lines really fast enough - it's 85 million lines per minute.

This seems to be where the time went. The only way that the query can be accelerated is to recover some of the conditions that must be applied before the grouping. The only obvious possibilities for this are

(a) filter values of zone_num

(b) move the audit only

NOT EXISTS (SELECT null from warehouse w WHERE w.zoneid = zrn.zoneid AND w.zone_createdate = zrn.zone_createdate AND w.dt_warehouse IS NULL)

within the group, because this condition is applied regardless of the values in calculated fields. The AREA ID, ZONE_CREATEDATE are not null, so I suggest to try:

SELECT ID area, zone_createdate

Of

(

SELECT ID area, zone_createdate,

MAX (CASE WHEN zone_num = 18 AND tranx_date 'n' IS NOT NULL, THEN 1 TIME zone_num = 18 AND tranx_date IS NULL THEN 0 ELSE-1 END) region_18,.

MAX (CASE WHEN zone_num = 110 AND not IS NOT NULL, THEN 1 TIME = 110 zone_num tranx_date AND tranx_date IS NULL THEN 0 ELSE-1 END) region_110,.

MAX (CASE WHEN zone_num = 135 AND tranx_date no IS NOT NULL, THEN 1 TIMES zone_num = 135 AND tranx_date IS NULL THEN 0 ELSE-1 END) region_135,.

MAX (CASE WHEN zone_num = 140 AND tranx_date 'n' IS NOT NULL, THEN 1 TIME zone_num = 140 AND tranx_date IS NULL THEN 0 ELSE-1 END) region_140

OF zone_view

where (IDZone, zone_createdate) NOT IN (select the zone ID, w warehouse zone_createdate WHERE w.dt_warehouse IS NULL)

and zone_num (18, 110, 135, 140)

GROUP BY IDZone, zone_createdate

) zrn

WHERE zrn.region_18 <> 0

AND ((zrn.region_110 = 1) OR (zrn.region_110 = - 1))

AND (((zrn.region_135 = 1) AND (there IS NOT (SELECT null from warehouse w WHERE w.zoneid = zrn.zoneid AND w.zone_createdate = zrn.zone_createdate AND w.dt_posting IS NULL))) OR (zrn.region_140 = 1))

OR ((zrn.region_18 >-1) AND (zrn.region_135 = - 1) AND (zrn.region_140)<>

OR ((zrn.region_110 = 1) AND (zrn.region_135 = - 1) AND (zrn.region_140 <> 0))

)

Unfortunately, if the plan of the query time estimates are correct, most of the duration of the query is spent doing a reading zone_view in a full analysis, and which will not be changed by this query.

If there are many rows for each (IDZone, zone_createdate) zone_view pair, then it is possible that an index on (area ID, zone_num, zone_createdate) would contribute to this request, especially if most (IDZone, zone_createdate) pairs are filtered with the NOT IN (select the zone ID, zone_createdate w warehouse WHERE w.dt_warehouse IS NULL). More radical but probably effective measure would be a functional on index

zone_view (zone_num, IDZone, zone_createdate, case when tranx_date is null then 0 otherwise 1 end)

and using the expression in the query box:

SELECT ID area, zone_createdate

Of

(

SELECT ID area, zone_createdate,

NVL (MAX (CASE WHEN zone_num = 18 then case when tranx_date is null, then 0 or 1 end end),-1) region_18,.

NVL (MAX (CASE WHEN zone_num = 110 then case when tranx_date is null, then 0 or 1 end end),-1) region_110,.

NVL (MAX (CASE WHEN zone_num = 135 then case when tranx_date is null, then 0 or 1 end end),-1) region_135,.

NVL (MAX (CASE WHEN zone_num = 140 then case when tranx_date is null, then 0 or 1 end end),-1) region_140

OF zone_view

where (IDZone, zone_createdate) NOT IN (select the zone ID, w warehouse zone_createdate WHERE w.dt_warehouse IS NULL)

and zone_num (18, 110, 135, 140)

GROUP BY IDZone, zone_createdate

) zrn

WHERE zrn.region_18 <> 0

AND ((zrn.region_110 = 1) OR (zrn.region_110 = - 1))

AND (((zrn.region_135 = 1) AND (there IS NOT (SELECT null from warehouse w WHERE w.zoneid = zrn.zoneid AND w.zone_createdate = zrn.zone_createdate AND w.dt_posting IS NULL))) OR (zrn.region_140 = 1))

OR ((zrn.region_18 >-1) AND (zrn.region_135 = - 1) AND (zrn.region_140)<>

OR ((zrn.region_110 = 1) AND (zrn.region_135 = - 1) AND (zrn.region_140 <> 0))

)

This gives a very different plan on my database, by performing an iteration on relevant areas of performance status:

---------------------------------------------------------

| ID | Operation | Name |

---------------------------------------------------------

|   0 | SELECT STATEMENT |              |

|   4.     HASH GROUP BY.              |

|   5.      ANTI NESTED LOOPS.              |

|   6.       INLIST ITERATOR.              |

|* 7 |        INDEX RANGE SCAN | ZV_F1 |

|* 8 |       TABLE ACCESS BY INDEX ROWID | WAREHOUSE |

|* 9 |        INDEX UNIQUE SCAN | WAREHOUSE_PK |

| * 10 |   TABLE ACCESS BY INDEX ROWID | WAREHOUSE |

| * 11 |    INDEX UNIQUE SCAN | WAREHOUSE_PK |

---------------------------------------------------------

Your plan will be different because you have data volumes (I didn't create millions of lines of test data)

It would be useful to know how many rows there are in the WAREHOUSE, how many distinct (IDZone, zone_createdate) pairs there are in zone_view and the number of rows actually returns the query, and how much is NOT IN (select the zone ID, w zone_createdate warehouse WHERE w.dt_warehouse IS NULL) because these relative numbers determine how these approaches are.

If there is a table containing all of the (area ID, zone_createdate) pairs which could take place in zone_view, which would have may another possible approach:

First filter possible pairs against NOT IN (select the zone ID, w warehouse zone_createdate WHERE w.dt_warehouse IS NULL)

Then attach them to the zone_view to retrieve only the rows in the filtered (IDZone, zone_createdate) pairs.

Good luck.

Rewrite the query, select below or try to get the necessary O/P
Hello..

My example of data.,.

Create table customer (name varchar2 (10), telephone1 telephone2 number (10), number of phone3 (10), (10) number, bitwisephone number (10));

Insert into customer values('a',23456,67890,null,12345);

Insert into customer values ('b', 67459,89760,null, 37689);

create table do_not_call (dont_call number (10));

insert into do_not_call values (67890);

insert into do_not_call values (37689);

Question: -.
--------------

Customer 'a' has value of numbers1 as 23456.check if telephone1 exists in the do_not_call table.
In fact there is no, so set the bit for numbers1 as "o" like wise search telephone2
& phone3.after update of the bitwisephone for each client should be as the output below.

Need to O/P: -.
-------------------

name bitwisephone

a 010
b 001

For that matter... I use "any" operator...

SELECT name, case when numbers1 = all (SELECT dont_call FROM do_not_call) and then put an end to '1' other '0'.
-case when telephone2 = all (SELECT dont_call FROM do_not_call) and then put an end to '1' other '0'.
-case when phone3 = all (SELECT dont_call FROM do_not_call) then '1' other '0' end 'Bits '.
OF THE customer;

Is there any other way to get the necessary O/P?

Rewrite the query with joins, and group by

Hello

It's an interview question.

Table names: bookshelf_checkout
virtual library

And the join condition between these two tables is title

We need to rewrite under request without using the join condition and group by clause?

SELECT b.title,max(bc.returned_date - bc.checkout_date) "Most Days Out"
           FROM bookshelf_checkout bc,bookshelf b
           WHERE bc.title(+)=b.title
           GROUP BY b.title;

You think you're going to lines updates 85K, Oracle think it will update a line.

At the time where the existence of the first test runs that oracle think already up to 49 lines, which is probably why he uses the loop join nested for the second test. (In your version of Oracle, the subquery introduced existence a very bad assumption (small) on the amount of data will survive).

It is possible that you will get better performance if you hint Oracle using a hash join for testing the existence - and you might want to think what test will eliminate most of the data and that we can first force.

Having said that, however, note that MMR_DTL research is a considerable fraction of the cost of the query - and an analysis is an easy thing for Oracle cost properly - if, despite your comments on update a column with a clue to this topic, you will find that the query can be more effective if you use an index. This is more likely to be the case if data ' WHERE CAPITN_PRCS_IND = 5 AND HSPC_IND = 'Y' "is well grouped (perhaps the latest data added to the table).". " You could then reduce the cost of maintaining this index by creating an index based on a feature that indexes only the lines where the predicate are both true so that the 2 update deletes the index entries and allows the index remain as thin as possible.

How to adjust or rewrite lots of join not keys to multiple records on table table

Thank you

you have not answered my question. Are you really calling it 35 million times in 30 minutes?

If so, why?

Hi, PMP,

you have a clue about your date column?

Maybe a component base snap on 'trunc(ods_rbs#mobcdr_dst)' can help.

Query based ViewObject does pull not all attributes, when the query has 'WITH' clause

Hello
12.1.2 and 12.1.3 JDeveloper
When we try to create a custom query based ViewObject, and the query clause of "with."
So not all the columns selected in the query are appearing as attributes of the View object in the wizard.
This is the query. And it performs very well in Toad.
WITH dept_count AS)
SELECT department_id, COUNT (*) AS dept_count
Employees
GROUP BY department_id)
SELECT e.first_name AS employee_name,
DC1.dept_count AS emp_dept_count,
m.first_name AS manager_name,
DC2.dept_count AS mgr_dept_count
E employees,
dept_count dc1,
m employees,
dept_count dc2
WHERE e.department_id = dc1.department_id
AND e.manager_id = m.employee_id
AND m.department_id = dc2.department_id;
Only the EmployeeName attribute is extracted from the query. It does not show the rest of the attributes in the VO Wizard.
(I also tried to create a VO from the EntityObject class and make it editable as false, even in this case all attributes are not displayed.)
I was wondering if something changed in 12 c?
It works in 11.1.1.7
(A friend of mine just asked me this).
Thanks for any help.
Sameer

Jdev dislikes the syntax

You can rewrite as

SELECT e.first_name AS employee_name,

DC1.dept_count AS emp_dept_count,

m.first_name AS manager_name,

DC2.dept_count AS mgr_dept_count

E employees,

(

SELECT department_id, COUNT (*) AS dept_count

Employees

GROUP BY department_id) dc1,.

m employees,

(

SELECT department_id, COUNT (*) AS dept_count

Employees

GROUP BY department_id) dc2

WHERE e.department_id = dc1.department_id

AND e.manager_id = m.employee_id

AND m.department_id = dc2.department_id

who must work and give you the same result.

2.1 EA1: Query Builder does not update the query to display the results
When using the query designer, if you click view results to see the results of the current query, then return to "Select columns" or the tabs 'Create a Where Clause' change the query, the "View results" tab shows again the results of the original query, even if no tables or columns of the original query occurs. By clicking on the button run the report or by setting a refresh interval has no effect.

On another note, the query designer again is not reentrant, because you cannot select (highlight a part where cursor in) a query, and then open the query for this request of change graphically Designer.
Sentinel,

The problem is known and is listed in the known issues in the release notes for the first users. We hope to have this sent to production.

Returning Query Builder is always on our list of things to do. We intend to rewrite the Query Builder and examine a number of requests related to this function. I'm hoping to make it a priority for the next release.

When, on my home page, I click on the link "transparent popup" in the query "did you mean: transparent popup", NO RESULTS appear in this new tab; How to solve?

I had trouble due, apparently, to a file named popuptransparent [dot] xul, which I have 3 cases on my computer (Win XP/Firefox last v.). Using my window of AVG home page, I get "popuptransparent" (try to fix) and the results appear OK. But then when I click to a new tab, on the "transparent popup" link in the query "did you mean: transparent popup", NO RESULTS appear in this new tab. In addition, when I reload then the Panel of AVG which sought to 'popuptransparent' in the first place, it, too, shows now no results. Or a panel shows Google now no results. They show the quantity of results, but just white screens for the results themselves.

Links https://support.mozilla.org/en-US/questions/948804?esab=a & as = aaq and https://support.mozilla.org/en-US/questions/952141?esab=a & as = aaq brings me. I re-installed Firefox v. 20.0.1 nothing works. How to fix?

Should I remove it from my computer all 3 of these instances of xul [dot]?

Regarding the problem of searching, you can check the extension "Disconnect"? I think it could affect the Google sites and third parties who use Google. You can disable or try its button Options here:

Firefox orange (or the Tools menu) button > addons > Extensions category

While you're there, you can disable all extensions essential and unrecognized. When in doubt, turn off.

After restarting Firefox, did you notice a difference?

Could you explain in more detail the next part?

Should I remove it from my computer all 3 of these instances of xul [dot]?

Is this something that came in a security sweep? What question do you think they are originally? They are located in a folder extensions?

I need to stop a download of the query, I thought a stand-alone application but turns require a higher level (FCPX) as a 'parent' and I do not who have, or want to buy.

I need to stop a download of the query, that I thought a stand-alone application but turns require a higher level (FCPX) as a 'parent' and I do not have that, or I want to buy it.

Motion IS a stand-alone application. It is mainly designed to make effects for Final Cut Pro X, but it is not necessary to have with FCPX nor is it necessary to have FCPX to create projects for other purposes. When you open the query, simply select project of work outside the FCPX motion. You can save regular projects of Motion anywhere on your system.

How to activate the query suggestions

How the query suggestions can be enabled in the Firefox address bar?

You're welcome... good to know you got it working.
