How to optimize this query XMLDB
Hello dear community, we have two XMLType table they are very similar but not identical and we do not have the XSD for validation for this exercise.
We need to make a join between these tables and the data code example go like that
create table xmltst ( xmldata xmltype); create table xmltst2 ( xmldata xmltype); declare idata varchar2(4000); idata2 varchar2(4000); begin idata := '<?xml version="1.0" encoding="UTF-8"?> <SWs> <SW s_ID="T6B890.00-01" t_ID="T6B890.00"> <Ds> <De sX="59" sY="-57" rX="7" rY="22" m_ID="L" eTime_s="2014-12-12T02:22:11+08:00" eTime_e="2014-12-12T02:22:42+08:00" mst="0.631"/> <De sX="70" sY="-57" rX="7" rY="23" m_ID="L" eTime_s="2014-12-12T02:22:12+08:00" eTime_e="2014-12-12T02:22:33+08:00" mst="0.217"/> <De sX="69" sY="-57" rX="47" rY="1" m_ID="R" eTime_s="2014-12-12T02:22:16+08:00" eTime_e="2014-12-12T02:22:56+08:00" mst="0.974"/> </Ds> </SW> <SW s_ID="T6B890.00-02" t_ID="T6B890.00"> <Ds> <De sX="56" sY="-1" rX="72" rY="19" m_ID="R" eTime_s="2014-12-12T02:36:01+08:00" eTime_e="2014-12-12T02:36:29+08:00" mst="0.541"/> <De sX="57" sY="-1" rX="39" rY="42" m_ID="L" eTime_s="2014-12-12T02:22:12+08:00" eTime_e="2014-12-12T02:23:01+08:00" mst="0.426"/> <De sX="58" sY="-1" rX="72" rY="20" m_ID="R" eTime_s="2014-12-12T02:36:07+08:00" eTime_e="2014-12-12T02:36:18+08:00" mst="0.716"/> </Ds> </SW> </SWs>'; idata2 := '<?xml version="1.0" encoding="UTF-8"?> <SWs> <SW s_ID="T6B890.00-01" t_ID="T6B890.00"> <Ds> <De sX="59" sY="-57" rX="7" rY="22" m_ID="L" eTime_s="2014-12-12T02:22:11+08:00" eTime_e="2014-12-12T02:22:42+08:00"/> <De sX="70" sY="-57" rX="7" rY="23" m_ID="L" eTime_s="2014-12-12T02:22:12+08:00" eTime_e="2014-12-12T02:22:33+08:00"/> <De sX="69" sY="-57" rX="47" rY="1" m_ID="R" eTime_s="2014-12-12T02:22:16+08:00" eTime_e="2014-12-12T02:22:56+08:00"/> <De sX="72" sY="-57" rX="47" rY="2" armID="R" eTime_s="2014-12-12T02:22:18+08:00" eTime_e="2014-12-12T02:23:28+08:00"/> <De sX="82" sY="-57" rX="7" rY="25" armID="L" eTime_s="2014-12-12T02:22:19+08:00" eTime_e="2014-12-12T02:22:58+08:00"/> </Ds> </SW> <SW s_ID="T6B890.00-02" t_ID="T6B890.00"> <Ds> <De sX="56" sY="-1" rX="72" rY="19" m_ID="R" eTime_s="2014-12-12T02:36:01+08:00" eTime_e="2014-12-12T02:36:29+08:00"/> <De sX="57" sY="-1" rX="39" rY="42" m_ID="L" eTime_s="2014-12-12T02:22:12+08:00" eTime_e="2014-12-12T02:23:01+08:00"/> <De sX="58" sY="-1" rX="72" rY="20" m_ID="R" eTime_s="2014-12-12T02:36:07+08:00" eTime_e="2014-12-12T02:36:18+08:00"/> </Ds> </SW> </SWs>'; insert into xmltst values (idata); insert into xmltst2 values (idata2); end; commit;
The SQL code, we try to optimize:
with tt as ( SELECT /*+ materialize */ x.* FROM xmltst t, XMLTABLE ('/SWs/SW[@s_ID="T6B890.00-01"]/Ds/De' PASSING t.xmldata COLUMNS sX number PATH '@sX', sY number PATH '@sY', rX number PATH '@rX', rY number PATH '@rY', eTime_s varchar2(30) PATH '@eTime_s', eTime_e varchar2(30) PATH '@eTime_e', mst number PATH '@mst' ) x ) ,tt2 as ( SELECT /*+ materialize */ x.* FROM xmltst2 t, XMLTABLE ('/SWs/SW[@s_ID="T6B890.00-01"]/Ds/De' PASSING t.xmldata COLUMNS sX number PATH '@sX', sY number PATH '@sY', rX number PATH '@rX', rY number PATH '@rY', eTime_s varchar2(30) PATH '@eTime_s', eTime_e varchar2(30) PATH '@eTime_e' ) x ) select tt2.*,tt.mst from tt2 left outer join tt on (tt2.sX = tt.sX and tt2.sY = tt.sY and tt2.rX = tt.rX and tt.rY=tt.rY)
CREATE INDEX xmltst_idx ON xmltst (xmldata) INDEXTYPE IS XDB.XMLIndex PARAMETERS ( 'XMLTable SW_tab ''/SWs/Sw'' COLUMNS s_ID VARCHAR2(100) PATH ''@s_ID'', sX NUMBER PATH ''Ds/De/@sX'', sY NUMBER PATH ''Ds/De/@sY'', rX NUMBER PATH ''Ds/De/@rX'', rY NUMBER PATH ''Ds/De/@rY''');
Create an index as above, but it does not seem to be used to explain the plan for the part of XML query.
and a lot of time, I also get this error but I cannot now re - produce for some reason.
I thought that its because I can't index after branch out according to s_ID
SQL Error: ORA-29879: cannot create multiple domain indexes on a column list using same indextype 29879. 00000 - "cannot create multiple domain indexes on a column list using same indextype" *Cause: An attempt was made to define multiple domain indexes on the same column list using identical indextypes. *Action: Check to see if a different indextype can be used or if the index can be defined on another column list.
and this index below seems to have choice as shown explain plan.
Why can't I see the index above in the plan to explain it?
CREATE INDEX "OE"."XMLTST_INDX01" ON "OE"."XMLTST" ("XMLDATA") INDEXTYPE IS "XDB"."XMLINDEX" PARAMETERS ('paths (include (/SWs/SW/@s_ID))');
However, it is still the loop nest join when the join of two tables after the XML in the process... Is it possible to tell Oracle to a join index or some kind of faster join after the XML select part.
My real case got way as many lines to make the join of X - Y and it may be nice to have an index to quickly reach?
When do some small tests, the clause will eventually cause oracle core dump. It should not happen even it is a virtual machine with 3G of memory max and the max_memory_target = 800 M as all my data are not not even 50 M.
We are the team of analysts and Dev team suggest that is a little too much time to contact Oracle Support and I finally create 3 global temporary table with commit preserve rows and operate with performance much better.

How to optimize this query?
Hello

and t1.id = t2.id)
where value_match is not null)
where rnk = 1) s
on (st1.pk = s.pk)
WHEN MATCHED THEN
Update set st1.value = s.value_match, st1.diff_value = s.diff_value, st1.up_date = s.m_date
where st1.value is null.
Explain the plan:
Table1 a record 3Million and table 2 has 1 million records.
I used gather stats before you run this query and 'Full' trick, even in this case, he is running for 45 minutes.
Please suggest the best solution to optimize this query.
Thanks in advance.
Remove the tips.
No need for the separate.
Get the diff by ceil (abs(t2.m_date-t1.m_date)) and the filter for that where value_diff<>
Assing the statement ".. MATCHED" lately in the update clause.
Maybe give exactly to your needs with a small example may be the query may be getting more simplified or not what you want it to do.

How to write this query in the hierarchy
Hi gurus,
Really need your help on this query. Thank you very much in advance.
SELECT t1.key as root_key , (SELECT t2.unit_id AS unit_id level-1 AS level , t2.name, t2.creator FROM tab t2 START WITH t2.unit_id = t1.unit_id -----check each node as root CONNECT BY prior t2.unit_id = t2.parent_unit_id ) t1.name as parent_unit_name FROM tab t1
I'll write a query of the hierarchy as above, and that EACH line (node, totally more than 10200) is checked as root node to see how many sheets are accessible for her... It must be implemented in a single query.
I know inline query should NOT return multiple rows or multiple columns, but the inline elements are necessary and can certainly be made in a correct solution.

How to write this query?
Hi people,
I need to get a query in which a set of records, I get ONLY those which previous registry has a field with a value to this topic. Other values, the field can contain are not necessary.
I know that sounds easy but... I can't get it.
So, for Oracle 10 g 2... Here's my query:
SELECT a.person_id, a.person_status, a.message_id, a.order_id
OF t_HR one
WHERE a.person_status = "rejected".
AND a.id >
(SELECT max (b.id)
OF t_HR b
WHERE b.person_id = a.person_id
and b.order_id = a.order_id
AND b.person_status! "revised =".
B.ID AND < a.id)
ORDER BY desc a.id
Let me explain:
1 - HR table is a table of people. These people has serveral STATUS.
2 - ID is a sequential (each www.voyages-sncf.com has a different identification number).
3 - the application must get THAT all people "rejected".
4. - However, (subquery) I need ONLY those that previous register (the second register) holds a status of "OK". If the person holds a "revised" status he's not, he should be the next register (the third)
5.-L' ORDER ID DESC, so is the first register must have a STATUS = "rejected" and the second a 'OK '. IF the second register = "revised", then the third register must be 'OK '. And I need this query.
HOW DO?
My problem: the subquery gives you previous register of the same guy, but... it does not give you the value of the State, I need, which is 'OK '.
I tried to add to the subquery...
SELECT max (b.id)
OF mod_human_resource b
WHERE b.person_id = a.person_id
and b.order_id = a.order_id
AND b.person_status = 'OK '.
AND b.id < a.id
... but if I have 5 records of that person, the first is "rejected", the second is "accepted", the third is 'new' and the fourth is 'OK'... the subquery gives you the 4th register and which is not correct for me, it must be only the second one (prior to the first State registry).
I need to be a query, because I need to use it on a MERGER for a DWH.
If there is another way (function, or even a procedure) to make the MERGER rather than with a request, which would be ok too. I am poor DWH knowledge.
Thanks in advance.
Hello
So, you need to know if a line is the 'first' line, and you should also know what is the 'next' status, (even the 'first' and 'next' are already defined). This sounds like a job for analytical functions. ROW_NUMBER can tell you if a line is first or not, and LEAD can tell you what a value on the next row.
Since you post CREATE TABLE and INSERT statements for your own table, I'll use the table scott.emp to illustrate.
Consider these data from scott.emp:
SELECT DeptNo
ename
work
FROM scott.emp
ORDER BY deptno
ename DESC
;
Output:
DEPTNO ENAME JOB
---------- ---------- ---------
10 MILLER CLERK
PRESIDENT OF KING 10
MANAGER 10 CLARK
20 SMITH CLERK
ANALYST SCOTT 20
20 JONES MANAGER
20 FORD ANALYST
20 ADAMS CLERK
30 WARD SALESMAN
SELLER OF 30 TURNER
30 MARTIN SALESMAN
30 JAMES CLERK
MANAGER BLAKE 30
30 ALLEN SALESMAN
Now, let's say we want only who know the departments where the forefront (in order descending ename) a job = 'CLERK', and the following line (also in descending by ename order) = "ANALYST" job, and we want to know the ename of the first row. In other words, the correct output is:
DEPTNO ENAME
---------- ----------
20 SMITH
Note that deptno = 10 is not included, even if the first task is to "CLERK." that was because the second job in deptno = 10 is the "PRESIDENT", not "ANALYST."
Here's a way to get these results:
WITH got_analytics AS
(
SELECT ename, deptno, job
ROW_NUMBER () OVER (PARTITION BY deptno
ORDER BY ename DESC
) AS r_num
LEAD (employment) OVER (PARTITION BY deptno
ORDER BY ename DESC
) AS next_job
FROM scott.emp
)
SELECT deptno, ename
OF got_analytics
WHERE r_num = 1
AND job = 'CLERK '.
AND next_job = 'ANALYST '.
;
I hope that answers your question.
If this isn't the case, then, as Dan (and the FAQ forum) said, post CREATE TABLE and INSERT statements for some sample data and the exact results you want from these data.
Post your query, based on the one I have posted more top and ponit out where he gets results.
Always say what version of Oracle you are using (for example, 11.2.0.2.0).

How to optimize the query with a join of virtual tables
I'm working on a query that is get the data of virtual tables 2 and b
one is formed by the Union, all say 4 queries and b is formed by the Union, all say 3 queries
then these two virtual tables and b are joined on a column common and data are extracted from their part.
Problem is that there is about 1 minutes each in the two virtual tables has and b. If individual a and b queries virtual takes about 5 seconds to retrieve data
but the join on column takes about 25 seconds to retrieve data.
Can someone guide me how to optimize the recovery of joining 2 virtual tables having large data

How to optimize this code?
Hi all
The function I want to achieve is very simple. The reading of data from data acquisition, play the sound file if a rising edge is detected and stop playing if a front down is detected.
Attachment is my code, it works, but if I stop the program and restart it, the program will be somewhat stuck (but), so all I can do is to put an end to the task and to reopen the program. I put two structures case for each channel, I believe that the problem is caused by the second case structure.
I am a beginner of labview, could someone optimize me this code?
Thank you!
First, use the charts to your advantage. You can do this fairly simple dynamic conversion of the Data Type in a table of waveforms. Trigger detection can treat an array of waveforms. You can then process all detections of relaxation in a loop, updated what trigger (and level), that you are looking for dynamically.

Leave_Status_text StatusText, NVL (pt.punchtype, 'day') JOIN employee E ON PunchForApproval pa e.Emp_ID punchtype is pa. Empcode LEFT JOIN Leave_status ls TO ls. Leave_Status_id = pa.approve LEFT JOIN punchtype pt ON pt.id = pa. STATUS
WHERE E.Emp_ID IN (SELECT Emp_id FROM employee) ORDER BY pa.id DESC;
Thank youHello
You run this in a PL/SQL procedure? If so, what the procedure called the request?Also, did you see the error even if you add a space to the request here.
WHERE E.Emp_ID IN (SELECT Emp_id FROM employee) ORDER BY pa.id DESC;
-implement-
WHERE E.Emp_ID IN (SELECT Emp_id FROM employee) ORDER BY pa.id DESC;
Kind regards

How to use this query in oracle?
Hi Sir,
I use a SQL query that is
declare @date date ='2012-10-25', @date1 varchar (5)
Set @date1 = DATEPART (W, @date)
impression @date1
that its value means day 25 oct 5 back Thursday it is checking and counting from Sunday in this week so the result is 5 next.
and storing in @date1
the same result I want in oracle.
Thank youTry this...
