Inconsistent results returned from the same query

Hi,
My company has a oracle 8i DB as backend for the website it is currently hosting. I wrote a plain SQL select query to retrive results from a table. Usually the query returns 50 to 100 records. We build an xml based on the results and cache the xml for subsequent user hits.
But atleast once or twice a day we get a problem where it returns almost no records. So the resulting xml will be blank and from there on until we delete the cached xml the user sees the page as blank.
I wonder why this happens, does this happen because of more hits to the oracle database?. Or is it because of the indexes created on the table?. Is oracle not able to handle multiple user requests?. We get mostly like 10 to 20 people clicking at the same time. I don't know what is causing the failure.
Does any of you have this inconsistency problems with Oracle?
Thanks in advance

Please post DDL, so that people do not have to guess what the keys, constraints, Declarative Referential Integrity, data types, etc. in your schema are. Learn how to follow ISO-11179 data element naming conventions and formatting rules (you have no idea).
Temporal data should use ISO-8601 formats. Code should be in Standard SQL as much as possible and not local dialect.
What you did post is bad SQL.
The prefix “tbl-” is a design flaw called tibbling and we do not do it. We seldom use temp tables in RDBMS; it is how magnetic tape file programmers fake scratch tapes.
If the schema is correct, then SELECT DISTINCT is almost never used.
Your “bill_parent” looks like a assembly language bit flag; we never use those flags in SQL.
“Funding_Type_Status” is an absurd name for a table. A status is a state of being, not an entity. A type is an attribute property. So this table ought to be column that is either a “funding_type” or “funding_status” (with the time period for the state of being
shown in other columns). But this hybrid is not possible in a valid data model.

Multiple resultsets from the same query?

Hi all,
Can I define a query that will show more than one resultset (of similar structure), based on the different values of a particular characteristic?
Say, characteristic C1 has 3 different values x1, x2 and x3. Is it possible to output 3 different resulsets based on x1, x2 and x3?
Thanks,
Satyajit.

Hi Satyajit,
I hope i am getting your problem right.
By saying "3 different resulsets based on x1, x2 and x3"
did u mean to say that the list of key figures u have specified in your columns portion of your query should be displayed 3 times,First with x1, then with x2 and then x3.?
If thats the case what u can do is drag the characteristic C1 into the columns section of your query designer and keep it in top , followed by the key figures.
Then you can achieve the desired result..
Hope it helps.

Parth.

How can I show all the results returned by a sql query?

Hi guys,
I need your help.
Let's say I have one table: TableA. Fields of TableA are aleg, anon, apes. The following sentence can return, in general, several rows: select anon from TableA where aleg = somevalue. I'd like to show the result of column anon but no luck. If I try to show the results in a TextArea and the origin is an sql query only shows the first row value. I tried Show as: show as text (based in PLSQL) and coding an anonymous plsql block as
DECLARE
v_anon TableA.anon%TYPE;
CURSOR v_cur IS
select anon from TableA where aleg = somevalue;
BEGIN
OPEN v_cur;
LOOP
FETCH v_cur INTO v_anon;
EXIT WHEN v_cur%NOTFOUND;
:FIELD_IN_FORM := v_anon;
END LOOP;
CLOSE v_cur;
END;
but in this case it's not shown any result.
So the first question is what kind of field should I use to show the result. And the second one is what can I do to being able to show all the results returned by the query (provided that is more than one single row).
regards

Hi Denes,
Just starting with apex. I think I know how to show the results in a report region. I've simplified the posted question.
A more detailed question would be: Suppose you have a region where you have put several text areas to accommodate the result of a multi-column query (lets say for TableA) that only returns one row, each column value returned put in a different text area. Also you want to show the values of other fields in TableB that depends on some value just retrieved from TableA and that you want all values retrieved (from TableA and the linked TableB) to be show in the same region. Is that possible? If yes, how?
Thank you in advance

Different results for the same query and same data ! (oracle 9i)

Hi,
This is a mystery for me. I've got on my database exactly the same data that my customer (exported schema). We both launch the same query (generated by the software that we sold him). This query has a criteria IN (SELECT MAX()...) to get only data from the last year.
The query gives 477 rows on my computer (correct answer), but no row on his! We have the same data! The only difference is the Oracle release : 9.2.0.6.0 for him, 9.2.0.1.0 for me.
If he executes the subquery alone, it gives the expected result.
If he replaces the MAX() in the subquery by the returned value (year 2016), he gets his 477 rows.
I've rewritten the query with a NOT EXISTS, and now all is fine. (Less efficient but it works).
I have no rational explication. Did I miss something ?
Thanks for any answer.
This is the query:
SELECT ...
FROM
CRA, GRA, ...
WHERE
/* subselect */
(CRA.COLLCOD, CRA.CRANEXE, CRA.CRANCODBUD, CRA.GRANNUM, CRA.CRANCOD1, CRA.CRANCOD2, CRA.CRANCOD3, CRA.CRANCOD4)
IN (
SELECT b.COLLCOD, MAX(cranexe), b.CRANCODBUD, b.GRANNUM, b.CRANCOD1, b.CRANCOD2, b.CRANCOD3, b.CRANCOD4
FROM CRA b
GROUP BY b.COLLCOD, b.CRANCODBUD, b.GRANNUM, b.CRANCOD1, b.CRANCOD2, b.CRANCOD3, b.CRANCOD4
AND... /* other filters and joins */

v9.2.0.1 was full of bugs. a lot of these bugs had to do with "incorrect results", typically associated with old stats or complex queries (certain types of subqueries were very likely to give wrong resutls, due to the way they were rewritten by the optimizer).
apply the 9.2.0.6 patch set

Compare two results from the same table

i have two results from the same table that i would like to compare. below is my query and the results i want to compare
SELECT tblItemRoutingBOM.ItemRevID, tblItem.ItemID, tblItem.PartNum, tblItem.ItemName, tblItem.ManufacturerPartNum AS [Mfg Part#], tblItemRoutingBOM.Quantity
FROM tblItemRouting
INNER JOIN tblItemRoutingBOM ON tblItemRouting.ItemRoutingID = tblItemRoutingBOM.ItemRoutingID
INNER JOIN tblItem ON tblItemRoutingBOM.ItemID = tblItem.ItemID
WHERE tblItemRoutingBOM.ItemRevID in (61,70)
as you can see i am returning two records using the where clause
ItemRevID, ItemID, PartNum, ItemName, Manufacturer, Mfg Part#, Quantity
61,121,331503,.233 Aluminum Sheet,,1
70,121,331503,.233 Aluminum Sheet,,3
now what i am looking for is to combine these two together into one row with the following added. two columns for each QTY, QTY1 = 1 and QTY2 = 3 with a third column added that is the difference between the two QTY Diff = 2
Any thoughts?

Here are the two statements that i want to combine, results for each are attached
SELECT tblItem.ItemID, Sum(tblItemRoutingBOM.Quantity) AS SumOfQuantity, tblItem.PartNum AS [Part #],
tblItem.ItemName, tblManufacturer.ManufacturerName AS Manufacturer, tblItem.ManufacturerPartNum AS [Mfg Part#]
FROM tblItemRouting
INNER JOIN tblItemRoutingBOM ON tblItemRouting.ItemRoutingID = tblItemRoutingBOM.ItemRoutingID
INNER JOIN tblItem ON tblItemRoutingBOM.ItemID = tblItem.ItemID
INNER JOIN tblUnits ON tblItem.UnitID = tblUnits.UnitID
LEFT JOIN tblManufacturer ON tblItem.ManufacturerID = tblManufacturer.ManufacturerID
WHERE tblItemRoutingBOM.ItemRevID=61
GROUP BY tblItem.ItemID,tblItem.PartNum,tblItem.ItemName,tblManufacturer.ManufacturerName,tblItem.ManufacturerPartNum
SELECT tblItem.ItemID, Sum(tblItemRoutingBOM.Quantity) AS Quantity, tblItem.PartNum AS [Part #],
tblItem.ItemName, tblManufacturer.ManufacturerName AS Manufacturer, tblItem.ManufacturerPartNum AS [Mfg Part#]
FROM tblItemRouting
INNER JOIN tblItemRoutingBOM ON tblItemRouting.ItemRoutingID = tblItemRoutingBOM.ItemRoutingID
INNER JOIN tblItem ON tblItemRoutingBOM.ItemID = tblItem.ItemID
INNER JOIN tblUnits ON tblItem.UnitID = tblUnits.UnitID
LEFT JOIN tblManufacturer ON tblItem.ManufacturerID = tblManufacturer.ManufacturerID
WHERE tblItemRoutingBOM.ItemRevID=70
GROUP BY tblItem.ItemID,tblItem.PartNum,tblItem.ItemName,tblManufacturer.ManufacturerName,tblItem.ManufacturerPartNum

125,6,331504,Velvet Vinyl .008,NULL,
my returned result should combine above with two extra columns (two extra columns because i have two results to combine)

Columns go as such, ID, QTY1 (for 61), QTY2 (for 70), Diff (QTY1-QTY2), PartNum, ItemName, Mfg, Mfg Part#
IF the results from one of those two are empty then i would see something like this
114, 11, 0, 11, 55002, Pepsi Blue Cap, NULL,
117, 5, 0, 5, 331501, Marigold Yellow For ABS, NULL

Why do I get two different results from the same coefficients?

I am getting two different results from the Polynomial Evaluation function.
For the first one, I am getting the coefficients from a Polynomial Fit function. I feed the coefficients from the Fit function into the Poly Eval function and get the correct result of 12.8582 when I evaluate 49940.
For the second one, I create constant array of the SAME values that were returned from the Polynomial Fit function (i typed them in). However, I am getting an incorrect result of -120.7913 when I feed the constant array into the Poly Eval function when I evauate 49940.
How can this happen when I am using the same array values?
Attached is an image of what I am explaining.

Hi Altran,
are you sure about using the "same" coefficients?
Did you compare them? Did you (atleast) set the display properties to 17 significant digits?

URGENT HELP:I want that the query should return in the same way

I have a query
select id from tableid where id in(350,241,251)
This returns me in
241,251,350
I want that the query should return in the same way as specified in "in" clause.
ie output should be in 350,241,251.
I would really appreciate if anyone can help.

You can achieve what you want like this:
select id from tableid where id in (350,241,251)
order by decode(id,350,1,241,2,251,3)in this example the decode explicitly defines the order you want to retrieve the records in.

Optimize query results(timing) returned from custom search query

Casey can you send the following to Oracle Support as soon as you can, we need their input on optimizing returning search results.
To Oracle:
We have noticed in the IdocScript reference guide that there is a way to optimize the query results returning to the user.
Here is the scenario: We have created a custom web query where we send a query to the UCM and return a result using a custom template via url like so
http://dnrucm.dnr.state.la.us/ucm/idcplg?IdcService=GET_SEARCH_RESULTS&QueryText=dDocTitle <matches> `AGREEMENT` <AND> xStateLeaseNum<matches>`00340`&ResultCount=30&SortOrder=Desc&SortField=dInDate&urlTemplate=/ucm/groups/public/documents/oos/hcst-search.hcst
This works fine. The problem is that when a query is broader like
http://dnrucm.dnr.state.la.us/ucm/idcplg?IdcService=GET_SEARCH_RESULTS&QueryText= xStateLeaseNum<matches>`00340`&ResultCount=30&SortOrder=Desc&SortField=dInDate&urlTemplate=/ucm/groups/public/documents/oos/hcst-search.hcst
The query takes an extremely long time to execute and the results template sometimes never comes back, which seems like a timeout.
Is there something else that we can do to optimize the query results?

Hi John,
What version of xMII are you using?
Some things I would try:
1. Clear the Java Web Start Cache - see if that makes any difference.
2. If not, what happens if you save the query under a different name, and then try using it in a new transaction?
3. Please feel free to enter you case into xMII Support via the SAP Support Portal if you are unable to make this work.
Kind Regards,

SDO_FILTER and SDO_RELATE combined in the same query

Is it possible to combine these two operations?
I have a query that ideally should use SDO_RELATE for polygon data (some 25 million records). However it takes too long to run.
For curiosity's sake I tried using SDO_FILTER and again this takes hours. Again for curiosity's sake I combined the two and records are returned in about 2 mins. Please see the query below (to simplify matters I have used point data).
SELECT
FROM
table t
WHERE
MDSYS.SDO_RELATE(
t.geometry,
MDSYS.SDO_GEOMETRY( 2001,
null,
MDSYS.SDO_POINT_TYPE( 501900, 308000, null ),
null,
null
'mask=anyinteract querytype=WINDOW'
) = 'TRUE'
AND MDSYS.SDO_FILTER(
t.geometry,
MDSYS.SDO_GEOMETRY( 2001,
null,
MDSYS.SDO_POINT_TYPE( 501900, 308000, null ),
null,
null
'mask=anyinteract querytype=WINDOW'
) = 'TRUE'
As I see it, in this case SDO_FILTER is doing the primary filtering part. SDO_RELATE is doing primary filtering again followed by secondary filtering the resulting data which is why it is quicker. The data does appear to be correct.
Now am I barking up the wrong tree? Whether I am or not, why is this combination faster than individual use? I would appreciate any thoughts on this please.
Cheers guys
James

something else is going on, although without seeing the real query it is hard to know.
SDO_RELATE is a supoerset of SDO_FILTER. With SDO_FILTER and index query is done, with SDO_RELATE an index query is done, then the relate is done on the geometries returned by the filter query.
What kind of index are you using?
What version of spatial are you using?
Can you post the query window?
Are your geometries valid?

How to compare two fields from the same table in the select statement

Hi, friends
I try to compare tow fields from the same table, but no result,
For example, this
data: cptotchek tyep i.
select count(*) into cptotchek
from aufk where erdat = aufk-idat2 .
The result is cptotchek = 0, but there are the records in aufk , where, aufk-erdat = aufk-idat2.
Please, help me, i don't use the loop statement for optimize my program.
Regards

Hi ,
       it will not return any value   when you are using   column of same table
       such as Date Field   , Because while Using Aggregate Function it will not check with self column
.      For that you have to take data in one internal table and then you can work on it .
     And if you are worried about Performance it will not affect , untill you are selecting only required data .
you can try this way .
data: cptotchek type i.
types : begin of w_aufk.
        include structure aufk .
      types : end of w_aufk .
data : it_aufk type standard table of w_aufk with header line .
select * into corresponding fields of table it_aufk
from aufk .
loop at it_aufk .
if it_aufk-erdat = it_aufk-idat2 .
write : / it_aufk-erdat , it_aufk-idat2 .
else .
delete it_aufk .
endif .
endloop.

How to retrieve multiple columns using "returning" in the Insert query.

hi,
wanted to know how to retrieve multiple columns using "returning" in the Insert Query.
For retrieving one column we write the query as follows:
Insert into TABLE values(1,2,3,4) returning COLUMN1 into PARAMETER
But can we retrive multiple columns in the same query?
am using oracle 10g and coding in .NET

Hi,
You can definetely get multiple values from a single query using the 'returning' clause.
Eg : insert into emp (empno, ename, job, deptno) values (7324,'ADAM','MARKETING',30) returning ename, deptno into var1, var2; PN : var1 & var2 to be declared as varchar2 & number respectively.
More insight into the 'RETURNING' clause in this link.

Measure using UseRelationship not working well when sliced with attributes from the same table

Hi,
I have Measure created using the 'UseRelationship' Function, which uses a different datekey to link to the DateDim than the one the table is directly related by. The measure works as expected except in one scenario.
If I browse the measure using an attribute from the same fact table then the attribute is filtered using active relationship whereas the measure is filtered using the inactive relationship as shown below:
FACT(2 rows)(Active Relationship to Date using DateKey1)
SNo     DateKey1     DateKey2     Geo        Amt
1         20100101     20120101    India      100
2         20100101     20120101    US         200
AmtMeasure:=CALCULATE(SUM([Amt]),USERELATIONSHIP(FACT[DateKey2],'Date'[DateKey]))
If I browse the above measure in excel, with Year selected as 2012, I get 100+200=300. Now if I drag the Geo attribute against the measure I get 2 rows with 100 and 200.
If I do the same in a power view report I don't get any results after dragging the Geo attribute, whereas I get the correct value of 300 without the geo attribute. I checked the DAX query which the power view generates and figured this is being caused because
there are no rows in the table with DateKey1 having year 2012. I understand why this is happening this way in a DAX query and not in MDX, but shouldn't both behave in the same way and what is a work around.
Thanks,
Sachin Thomas

Fetching a partial range of selected result rows from the client side

It has been a while since I started trying to solve this Oracle puzzle.
Basically, what I need it is a way to fetch from the client side a run-time
defined range of result rows of a arbitrary SELECT query.
In low-end databases like MySQL I can do it simply by appending the LIMIT
argument to the end of the SELECT query statment passing the number of
the first row that I want to be returned from the server from the total
result rows available in the result set and the maximum number of rows
that it may return if available.
In higher end databases I am supposed to use server side cursors to skip
any initial rows before the first that I want to retrieve and fetch only
the rows I want up to the given limit.
I am able to achieve this with PostgreSQL and Microsoft SQL server, but I
am having a hard time with Oracle. The main problem is how do I fetch
result rows from a server side cursor and have their data returned to a
client side in a result set like in a straight SELECT query?
I was able to create a cursor and fecth a row into a server side record
variable with the following PL/SQL code.
DECLARE
CURSOR c IS SELECT * FROM my_table;
my_row c%ROWTYPE;
BEGIN
OPEN c;
FETCH c INTO my_row;
CLOSE c;
END;
I want to do this from PHP, so I don't have client side ESQL variables to
store the result set data structure. Anyway, if I can do it just with
SQLPlus I should be able to do it in PHP.
If I do straight SELECT I can get the result set, but in a PL/SQL script
like the one above I don't seem to be able to select the data in the
fetched row record to have returned to the client. Does a straight SELECT
query sends the result rows to a default client side variable?
If anybody can help, I would appreciate if you could mail me at
[email protected] because I am not able to access this forum all the time in
the Web. BTW, is it possible to access this forum by e-mail?
Thanks in advance,

Hello Jason,
On 03-Feb-00 05:34:14, you wrote:
I'm not sure I totally understand your problem, but I think you might be able
to solve it by using the ROWNUM variable. ROWNUM returns the sequenc number
in which a row was returned when first selected from a table. The first row
has ROWNUM = 1, the second has ROWNUM = 2, etc. Just remember that the
ROWNUM is assigned as soon as it's selected, even before an order by. So if
you have an order by clause, it'll mess it up. Here's an example. I hope
that helps.I though of that before but it doesn't help because if you use ORDER BY the
first result row might not have ROWNUM=1 and so on. Another issue is that
I want to be able to skip a given number of result rows before returning
anything to the client.
The only way I see to do it is to get the rows with server side cursor.
But how do I return them to the client? Where does a normal select returns
the rows? Isn't there a way to specify that the fetch or something else
return the rows there?
