Fast and slow when issued by app SQL query on the issue mnaually
HelloI have a more general question concerning a specific behavior of Oracle.
I update a feature of an application. The application is not responding and I finally put end. I checked Oracle if a request is long running by using the following statement:
Select s.username,s.sid,s.serial#,s.last_call_et/60 mins_running, q.sql_text from v$ session s
Join v$ sqltext_with_newlines q
On s.sql_address = q.address
When status = 'ACTIVE'.
Type <>'BACKGROUND '.
and last_call_et > 60
order of sid, serial #, q.piece
The result of the above query is:
WITH CONNECTION AS (SELECT * FROM WW_CONN C WHERE (C.FID_FROM I))
N (SELECT FID FROM WW_LINE WHERE FID_ATTR =: B1) AND C.F_CLASS_ID
FROM = 22) OR (C.FIDto IN (SELECT FID FROM WW_LINE WHERE FID_AT))
TR =: B1) AND C.F_CLASS_ID_TO = 22)) SELECT MIN (P.FID_ATTR) AS FI
CONNECTION C, WW_POINT D_FROM P WHERE (P.FID = C.FID_FROM A
C.F_CLASS_ID_FROM ND = 32 AND C.FLOW = 1) OR (P.FID = C.FID_TO
C.F_CLASS_ID_TO ND = 32 AND C.FLOW = 2)
I have another tool that shows me the connection parameter values. So I know that the value of: B1 is 5011 - the id of the feature updates. This query runs for 20 minutes and finally more time stops in front of him. The update process involves several sql statements - if it does not have the update, but is part of the process.
Here's the bit I don't understand: when I run the query in SQL Developer with value 5011: B1 it takes 0.5 seconds to return a result.
Why did the sql statement taking so long on the issue by the application, but takes less than one second when I run it manually?
I sent a dump of the data to the vendor of the application that is not able to reproduce the problem in their environment. Could someone explain to me what is happening here or give me key words for the search?
We use 11 GR 2, 64-bit.
Thank you very much
Rob
Hi Rob,
at least, you should see some differences in the statistics for the child cursor different (one for running the application must show at least a higher value for ELAPSED_TIME). I would like to use something like the following query to verify the information for the child cursors:
select sql_id
, PLAN_HASH_VALUE
, CHILD_NUMBER
, EXECUTIONS
, ELAPSED_TIME
, USER_IO_WAIT_TIME
, CONCURRENCY_WAIT_TIME
, DISK_READS
, BUFFER_GETS
, ROWS_PROCESSED
from v$sql
where sql_id = your_sql_id
Concerning
Martin

The fan frequently betwenn oscilates fast and slow
My satellite phone to old is 15 months - for the past 2 months, he developed a tendency to switch from one mode of ventilation of fast and slow in a cycle of a second. A colleague IT tried air compressed to clean any dust - this made little difference.
Is this likely to lead to failure problem? Is this a case of dissambling fan housing and more thorough cleaning? Any suggestion would be appreciated.

Single SQL query for the analysis of the date of customs declaration under the table of Stock codes
Dear all,
Please tell us a single SQL query for the below,
We have a Table of Stock as shown below,
STOCK_TABLE
ITEM_CODE
(item code)
BAT_NO
(lot no.)
TXN_CODE
(transaction code)
DOC_NO
(number)
BOE_DT
(date of the customs declaration)
I1
B1
I1
I2
I3
B70
I4
B80
I5
B90
T102
1234
JULY 2, 2015
I6
B100
We have to find the date of customs declaration (i.e. the date when the items have come under this particular table) for items that are not attached to any document (that is, who have TXN_CODE, DOC_NO and BOE_DT fields with a NULL value).
For each item in the table of actions, which is not attached to any document, the customs declaration date is calculated as follows.
- If (code section, lot number) combination is present under HISTORY_TABLE, the date of customs declaration will receive the UPDT_DT, the transaction code (TXN_CODE) is an IN or transactions (which can be analyzed from the TRANSACTIONS table).
- If (code section, lot number) combination is NOT currently at the HISTORY_TABLE (or) the transaction code respective to item - batch number combination code is an operation then customs declaration date will be the date of the document (DOC_DT) that we receive from one of the 3 tables IN_TABLE_HEAD that contains the element of that particular lot.
- If the case 1 and case 2 fails, our customs declaration date will be the last date of document (DOC_DT) that we receive from one of the 3 tables IN_TABLE_HEAD containing that particular item and the BAT_NO in expected results will be that corresponding to this document, as appropriate, to another NULL.
- If the case 1 or case 2 is successful, the value of the last field (in the output expected, shown further below) BATCH_YN will be 'Y', because it fits the lot. Otherwise it will be 'n'.

Vs. runtime vs. ViewObject ViewObject SQL query in the xml file.
Hello
I wonder what is the difference between query SQL in the long term, creating a view object in the duration and the creation of a display with an XML object.
I'm not trying to have the result set cached just to pick once.
My code for a creation of a view in a run-time object:
HashSet<Integer> allPersonIdThatUserHasAccessTo = new HashSet<Integer>(); AppModuleImpl am = (AppModuleImpl)ADFUtils.getApplicationModuleForDataControl("AppModuleDataControl"); String sqlStr = "SELECT up.person_id FROM user_person up where up.user_id = " + userId; ViewObjectImpl vo = (ViewObjectImpl)am.createViewObjectFromQueryStmt("AllPeopleUserHasAccessToVo", sqlStr); vo.executeQuery(); RowSetIterator rsi = vo.createRowSetIterator(null); while (rsi.hasNext()) { Row personRow = rsi.next(); Integer personId = ((BigDecimal)personRow.getAttribute(0)).intValue(); allPersonIdThatUserHasAccessTo.add(personId); } rsi.closeRowSetIterator(); vo.remove();When should I use SQL query, when the view object use at time of execution and time to create the view object to an xml file?
In general you should not write this code in a managed bean. Access code or in your case creating a VO belongs behind the façade in the module of the application.
You can create the original Version, but the main difference is that it takes more time. Code everything that the definition of VO created in the data model of the application module would make too and it clears directly after the query only to create the same code again the next time you call the method.
If the goal is not to keep the data, you can create the hashset class and call executeEmptyRowSet() on the VO (https://blogs.oracle.com/smuenchadf/entry/what_does_executeemptyrowset_d for details). This way you only need a VO that takes a parameter and gets you the same result in less time.

Dynamic SQL query in the DB adapter
Hello
I want to use the following custom SQL query in the DB adapter:
SELECT EMP_ID, EMP_NAME, EMP_LOCATION FROM EMP WHERE EMP_ID IN (#iNPUT_PARAMETER)
the problem I'm facing is that I don't know at the time of the development that EMP_ID how much will be passed to the process so that I can not use the input parameter specific number. I cannot use it IN the query within which statement I concatenate all the EMP_ID separated by comma and passed under INPUT_PARAMETER, but when running, he read the full concatenated string as a single string rather than identify them as a list of different: with comma separation. could someone help me in this case
Thank you
SunilUse the following query with two parameters. Build the string with delimiter when running and pass this string and delimiter to query... (in this example, the input value would be the same for both Delimiter1 and Delimiter2.)
Select * from EMP WHERE deptno IN (SELECT SUBSTR (STRING_TO_TOKENIZE, DECODE (LEVEL, 1, 1, INSTR (STRING_TO_TOKENIZE, SEPARATOR, 1, LEVEL-1) + 1), INSTR (STRING_TO_TOKENIZE, SEPARATOR, 1, LEVEL)-DECODE (LEVEL, 1, 1, INSTR (STRING_TO_TOKENIZE, SEPARATOR, 1, LEVEL-1) + 1)) FROM (SELECT #StringToTokenizer | #Delimiter1 AS STRING_TO_TOKENIZE, #Delimiter2 AS DELIMITER FROM DUAL) CONNECT BY INSTR (STRING_TO_TOKENIZE SEPARATOR) ((, 1, LEVEL) > 0)

Remember, there is no order integrated to the rows in a table. The table you have posted is exactly the same as:
AA bb
-- --
1 FG
1 FG
2 SS
1 FG
1 FG
and both are exactly the same as:
AA bb
-- --
2 SS
1 FG
1 FG
1 FG
1 FG
If you use words like 'first', 'previous' or 'row' when it comes to lines, then we must define what these words mean. This is usually done by making reference to a column in the table. For example, if you had a column called r_num, like this:
AA bb r_num
-- -- -----
1 FG 1
1 FG 2
1 FG 9
2 SS 10
1 FG 10.5
Then, it would be wise to say things like 'the table starts with 3 lines consecutive "FG", followed by "SS". After that there is another "FG", which is the last line in the table, WHEN TRIE BY R_NUM. If the part about "WHEN SORTED BY R_NUM" is not known, the words 'begins '. "consecutive", 'followed', 'after' and 'last' have no meaning.
If (and only if) you have somehting like r_num in your table. Then you can get the resutls you want like this:
WITH got_group_num AS
(
SELECT aa, bb, r_num
ROW_NUMBER () OVER (ORDER BY r_num)
-ROW_NUMBER () OVER (PARTITION BY bb
ORDER BY r_num
) AS group_num
FROM table_x
)
SELECT SUM (aa) AS total_aa
, bb
OF got_group_num
GROUP BY bb
group_num
ORDER OF MIN (r_num)

If this table consists of

numbers for homewin, shoot, awaywin probability
and the final result as 1, X, 2
What I want is a sql query that returns to me for each hometeam, awayteam and (if possible in a single line)
all documents of the hometeam which had the same number of prior probability. For example:
CEARÁ (last line), I would like to the sql to show me all the records of CEARA who had _1.40 3.85 or 5.50_ in each of the three issues of probability, BUT the problem is that I do want separate lines... I can do so far is to calculate a sum of House probability, probability of drawing, close probability for each team but the same records are calculated again in each game of probability!
This means if CEARÁ has 1.40-3.85-5.50 in the past it will return me this line only once, and not 3 times (one for each set of probability)
I hope that I've done my duty,
Thank you for your time and lights

DA on updatable report items Sql query using the class
Request Express 4.2.5.00.08
10-11 g Oracle
I have a page, so it has a link/button when he clicks then modal region will appear. Modal region has a as a table (Type SQL Query (updateable report)). All work very well so far.
However, I've now added some complex things.
for example. My region is based on the query of SQL Type (editable report).
SELECT id, name of family, Traghetti, area, d_date, start_time, End_time, displacement, role of table where id =: P10_ID;
I can also add a new line of course.
My problem is, (point) Shift display based on the value of Start_Time point) and so I made sure the class for two items.
for example, Start_Time (' class = "st_tm" ') and Maj ('class to = "Shift_time" '). Start_Time is based on (LOV) and shift is off the point in the sql query, but change the Start_Time.
And now, I created the DA.
1. event: change
Selection type: jQuery Selector
jQuery Selector: .st_tm
Condition: No.
1. action: set value
Set type: Expression Javascript
The JavaScript Expression: $(this.triggeringElement) .val ();
The element affected: P10_X1 (it is a hidden item)
2. action: Plsql Code
Code: start to null; end;
Page items to submit: P10_X1
3. action: Plsql Code
Code: start
If: P10_X1 between '03' AND '11' then
: P10_X1: = 'EARLIES ';
elsif: P10_X1 then '12' and '18'
: P10_X1: = 'LATES ';
on the other
: P10_X1: = 'NIGHTS';
end if;
end;
Page items to submit: P10_X1
NOW another DA
Event: change
Article (s) P10_X1
Condition (in list)
value (HASTY, LATES, NIGHTS)
Action:
Set type: Expression Javascript
The JavaScript Expression: $(this.triggeringElement) .val ();
Affected item:
Selection type: jQuery Selector
jQuery Selector:. Shift_time
Well, I look forward all the above work well, but I'm having a problem.
If I have more than 1 lines on a modal region and if I change the Start_Time value for a row then MAJ (point) is changing but he effect on all lines.
I want, if I make the changes on the line line # 2 while only 2 # MAJ (point) must be not performed any other lines?
Help, please!
Kind regards
RI
I found the solution me thank you.
I removed all the DA mentioned above and created a new.
1. event: change
Selection type: jQuery Selector
jQuery Selector: .st_tm
Condition: No.
Scope of the event: dynamic and light on page load.
Action (Javascript code)
ROW_ID = $(this.triggeringElement).attr('id').substr (4);
If ($(this.triggeringElement). val() > = 03 &. val() $(this.triggeringElement))<= 11)="">
.Val ('EARLIES') $(«#f11_» + row_id);
}
ElseIf ($(this.triggeringElement). > 11 val() & $(this.triggeringElement). val())<= 18)="">
.Val ('LATES') $(«#f11_» + row_id);
}
ElseIf (. val() > $19 (this.triggeringElement)) {}
.Val ('NIGHTS') $(«#f11_» + row_id);
}
also created another DA because I have a disabled report items.
Event: before the page is sent.
$('_:_disabled').removeAttr ("disabled");
and finally created manual process of DML for tabular and everything works fine. (Insert, Update, and delete).
Kind regards.

SQL query for the region of the tree
Hello
I was wondering if someone is able to help me work on a SQL query, to format the data in the table required in a part of the tree... I've never used a tree and I'm fighting to get the right data (if possible).
The data in the table looks like this:
I want to put it in a tree, using level 1 level6 with a final layout that would look like this:
As you can see, the data are formatted in level6 down in the tree, but are filled in the table from level 1. Not all of the columns will be filled, so level2 for anyone 4 (France) is the equivalent of level in the tree like level6 to person 1 (Spain).
This is Apex 4.2.5
Oracle 11.2.0.3.0
Sample data:
CREATE TABLE employees ( employee VARCHAR2(100), level1 VARCHAR2(100), level2 VARCHAR2(100), level3 VARCHAR2(100), level4 VARCHAR2(100), level5 VARCHAR2(100), level6 VARCHAR2(100) ); INSERT INTO employees (employee, level1, level2, level3, level4, level5, level6) VALUES ('Person1','Team One','Recruitment','Human Resources','Fictituous Company','Murcia','Spain'); INSERT INTO employees (employee, level1, level2, level3, level4, level5, level6) VALUES ('Person2','Team Four','Testing','IT','Big Corporate','Hanover','Germany'); INSERT INTO employees (employee, level1, level2, level3, level4, level5, level6) VALUES ('Person3','Big Corporate','Hanover','Germany', null, null, null); INSERT INTO employees (employee, level1, level2, level3, level4, level5, level6) VALUES ('Person4','Brittany','France', null, null, null, null); INSERT INTO employees (employee, level1, level2, level3, level4, level5, level6) VALUES ('Person5','Team Three','Testing','IT','Big Corporate','Hanover','Germany'); INSERT INTO employees (employee, level1, level2, level3, level4, level5, level6) VALUES ('Person6','Public Relations','Government Agency','Brittany','France', null, null);Added example given.
Hello
Apex-user wrote:
Thanks Frank, this is a good example, I can work with that! Your assumptions are correct.
A question I came, however, is that I have a data segment that comes across poorly formatted so to speak... where only the lower levels (1-2, etc.) have been filled from the bottom up.
An example of this data would be:
- INSERT INTO employees (employee, level 1, 2, level3, level4, level5, level6) VALUES ('Person7', 'One Team', 'Test', null, null, null, null);
As you can see that if you rerun the select, the test team is now duplicated, both at the level of the root in the tree as it should.
You are not sure if the sql can be adjusted to account for this, or if it's too hard?
It is obviously a question of data and I am trying to solve this separately (extracted data from another system out of my control).
Thank you!
Sorry, I'm confused.
You say that my assumptions were correct. What includes supported that "If test ' occurs under 'IT' in a row, then the extent of the 'Testing' occurs, it must be under"IT "? Right after you say that assumptions are correct, you give an example where 'Testing' occurs under 'IT' to a single line, but it is not less 'IT' to another line and where is 'One Team' under 'Testing' in a line, but is 'One Team' under 'Recruitment' in another row.
When a situation like this occurs, how you cope? Whenever you have a problem, please post the exact results you want from the given sample data, and an explanation of how you get these results. If you don't know about what would be the ideal results, or if you are flexible on the exact results, then at least give an example and explain your reasons.
Maybe you want to change the got_parent of subquery like this:
WITH unpivoted_data AS
(
SELECT *.
Employees
UNPIVOT (node_name
FOR lvl (level1 AS 1
level2 AS 2
level3 AS 3
level4 AS 4
level5 AS 5
level6 AS-6
)
)
)
got_parent AS
(
SELECT c.node_name
MIN (p.node_name) AS a parent
Of unpivoted_data c
LEFT OUTER JOIN unpivoted_data p ON p.employee = c.employee
AND p.lvl = c.lvl + 1
GROUP BY c.node_name
)
SELECT LPAD (' ' ')
2 * (LEVEL - 1)
) || Node_name AS entity
OF got_parent
START WITH parent IS NULL
Parent = node_name PRIOR CONNECTION
;
In this way, if 'Test' is current 'IT' in one line, but not under what in another line, whether under would consider the 'IT' request and not to be a root. If 'One Team' sudden 'Testing' in a line, but under "Recruitment" in another line, it will be (arbitrarily) consider it under "recruitment".

SQL Query - store the result for optimization?
Good day experts,
I'm looking for advice on a report. I did a lot of analytical functions to get the basic data that I have to do my report and its takes about 50 min for SQL finish. Now, with these data, I need to create 3 different reports and I can't use the SQL even since there are a lot of aggregation (example would be product group in one case and by customer in 2nd). For each of these different group garages I need another report.
So how to create 3 reports of 1 SQL query without running the query 3 times?
First thing that comes to mind is to store the result set in a fictitious table, and then query the table since I get the basic data are about 300 lines and then perform different garages group.
Best regards
Igor
So how to create 3 reports of 1 SQL query without running the query 3 times?
You already know the obvious answer - store data 'somewhere '.
If any 'somewhere' depends on your needs and you have not provided ALL the.
MV - if the query is always the same, you might use a MV and make a complete refresh when you want that new data. The data are permanent and can be queried by other sessions, but the query that accesses the data is frozen in the definition of MV.
GTT (global temporary table) - If a NEW charge of data AND three reports will be ALWAYS executed by a single session and then data are no longer necessary so a TWG may work. The application that loads the TWG can be different for each race, but the data won't be available for a single session and ONLY for the duration of this session. So if something goes wrong and the session ends the data are missing.
First thing that comes to mind is to store the result set in a fictitious table, and then query the table since I get the basic data are about 300 lines and then perform different garages group.
Which is commonly called a "table of REPORT-READY." Those that are useful when data must be permanent and available for multiple sessions/users. Generally, there is a batch (for example the package procedure) that periodically refreshes / updates the data during a window of failure. Or the table can have a column (for example AS_OF) that allows it to contain multiple data sets and the update process let alone the existing data and creates a new set of data.
If your database is about 300 lines you can consider a table report and even use it to contain multiple data sets. Then, the reports can be written to query the data by using a value AS_OF that wraps and returns the appropriate data. You don't need a window of failure since the oldest data are still available (but can be removed when you no longer need.
If you need a set of data, you can use a partitioned table work (with only one partition) to collect the new set of data, then a SWAP PARTITION to 'swap' in the new data. Only, this "Exchange" takes a fraction of a second and avoids a window of failure. Once the swap done no matter what user query will get new data.

I want to map a combination of batch of degree for a class rooms group of such distance that they make full use of the maximum capacity of the class rooms within a group (ideally), or as close to this as possible. Can it be done with a SQL query?
Any response will be appreciated.
The SQL Scripts to generate the required tables and populate data is less to:

Published by: Bilal on December 27, 2012 10:07Bilal, thanks for the nice problem! Another possibility to double check is to write a small PL/SQL function that returns 1 if a duplicate id is found, then equate to 0: "NUMBER of RETURN of Duplicate_Token_Found (p_str_main in VARCHAR2, p_str_trial VARCHAR2). It should analyze the second string and could use p_str_main LIKE '%', | l_id | ', %' for each id. In any case, the query complete (without that) is given below:

I found the need to deduplicate regular expression:AND RegExp_Instr (r_c.itm_path | r_i.path, ',(\d+),.*?,\1,') = 0)
-
Page reports there are two 2 day points of selector (a datefrom and dateto a) as well as a text field with AutoComplete element
When the page load query is called
SELECT
"COL1",.
"COL2",.
"COL3",.
the "table".
WHERE MYDATES BETWEEN: DATEFROM AND: DATETO
Which returns no records as no dates have been set.
How can I modify this search in the clause WHERE on the date element is called only when the dates are chosen, and by default, all the records are displayed.
The other related issue is when I chose a from and to date and research when I return in the view page of report after consulting other pages in the application of the apex, the form fields are always met, how can I delete the session down for these fields when the user leaves the page?
I hope that all makes sense?To_date('01.01.2100', 'dd.mm.yyyy')will give erroneous results on 02.01.2100 :D
A solution (perhaps there's a cleaner...):
WHERE ((:DATEFROM IS NOT NULL AND mydates >= :DATEFROM) OR :DATEFROM IS NULL) AND ((:DATETO IS NOT NULL AND mydates <= :DATETO) OR :DATETO IS NULL)You can change the message "No data found" by changing the attribute of report "when no. found data Message."
EDIT: And for the 2nd question, Alex is right, but also be aware that Firefox retains the values of form element when the page refreshes, you must change the Security page 'Form Auto Complete' to 'Disabled' attribute if you do not want to keep the form element values.
