When is a query not a query?

I've been tasked with amending a site written by someone
else, and i've got a very strange problem with a particular query.
When i run the query in Query Analyser (replacing the
variables with their corresponding values) it all works fine, and
even copy-pasting it out of Profiler and into Analyser works fine,
but running it in the CF page produces weird results:
It claims not to be a query object, but has a recordcount
property
When i cfdump it, i get "1"
Accessing SelectForSend.article_id works fine as a single
value (the correct value of the first row returned) but attempting
to convert that using ValueList() produces:
The column article_id is not present in the query named
SelectForSend. It is likely that you have misspelled the name of
the column.
Attempting to use the query in a loop or output gives me
Attribute validation error for tag cfloop.
The value of the attribute query, which is currently
"SelectForSend", is invalid.
This all works fine on the live site on its CF5 server, but
not on my testing server on MX7.
I've attached the offending query here, if anyone has any
pointers on this it would be very much appreciated!! Example values
for the vars in the query are as follows:
SelectSubscribers.EID is a string equal to the user's
username
maxId is a int (1750, for example)
(Apologies for the formatting, or lack thereof!)

Cheers for that technical analysis MikerRoo ;)
The dbtype attribute of cfquery doesn't have any way to
explicitly select JDBC, and nor does the datasource in
administrator. I'm guessing therefore that it'll use JDBC by
default, which doesn't work either!
Cheers for your help anyway, time's running out on this so
i'll probably just work around it with a non-working version of the
site. If i do happen to figure out a solution i'll post it here...
Edit: The query runs fine on a page on its own within the
same application... it just gets stranger! Must be something within
the page that's throwing it off...

Copied query not changeable when "Changeable Original" setting used.

Hi
We are letting users create queries in Production. All the authorisations are working as designed. We have settings for query elements set to "Changeable Original" in the object changeability.
When a user creates a new query they can save it, change it, save copies, all as required. The expectation is that they would be able to copy a query that originated in another system but was transported and save it under a new technical name and change it. This is not possible. It is as though the system thinks that the copy originated in the other system and as such cannot be changed.
If we change the query elements to "Changeable Everything" it all works but we do not want this setting for obvious reasons.
Has anyone come accross this? Can anyone suggest a way to fix this issue?
Thanks
Gareth

Hi Chetan, VNK
Thanks for your replies...
We have made the decision to allow query developement to a limited user community in Production. This has it's own name space different from the name space used for the transported queries. There are many reasons for this approach which i won't go into (unless you want me to...)!
The users do have the correct access to create in production. They are able to create and change new reports within their namespace within their InfoArea and all that is working fine. I would expect that opening and existing query in production and saving a copy in their namespace, that the new query should be changeable. Would you not expect this? You are correct, i do not want them to be able to change queries that originated in the development environment but the name space control combined with the changeable original setting in object changeability should control this.
The error i get is not a transport error...it is a system changeability error suggesting that the system thinks the new query was not created in production.
Any further ideas?
Thanks
Gareth

MDX Query not retuern any data on my production server when i check service it is running

Hi All,
MDX Query not return any data on my production server when i check service it is running. when i restart my service i can able to run MDX Query and get data in my production server.

Hi Mnishcal,
According to your description, there is no data returned before restart Analysis Services, right?
We haven't experiencing such issue before. And we cannot reproduce this issue. In your scenario, can you reproduce this issue? Here is a post which explains why you might not see the data you expect when browsing a SQL Server Analysis Services cube that
processed successfully. Please refer to the link below.
http://social.technet.microsoft.com/wiki/contents/articles/19744.ssas-troubleshooting-data-is-not-visible-when-browsing-a-cube.aspx
Besides, are there any error on the log file? The msmdsrv.log file for the SSAS instance that can be found in \log folder of the instance. (C:\Program Files\Microsoft SQL Server\MSAS10.MSSQLSERVER\OLAP\Log)

BEx query not shown in BO 4.0; BICS

Hi,
I have a sample BEx query designed in Query Designer 7.x; I would like to use this query with Web Intelligence of BO 4.0. However, the query is not being displayed.
In CMC -> Authentication we have entered our SAP BW system and we are getting the roles imported. So the connection seems to work.
In the query I have turned on the option "Allow External Access to this Query" (but I think this isn't necessary for BICS?).
However, the query isn't displayed when creating a new WebI document based on BEx. Do I have to do some more steps?
Thanks!
Edit: I now created a new OLAP connection, our BO server can see the query and cube. But: I don't see this OLAP connection in Web Intelligence Rich Client. I am using the administrator login and have full access.
Edited by: SteveXI on Sep 7, 2011 5:29 PM

Hi,
I have created 2 OLAP connection in CMC with SSO and Predefined. (does not work with prompt).
I can see the list of queries from cube with predefined connection, but all are gredout!!. what could be the reason?
With SSO connection i get following error -
com.google.protobuf.UninitializedMessageException: Message missing required fields: bytesValue
Any input is much appreciated.
Thanks.

Why does not my query use an index?

I have a table with some processed rows (state: 9) and some unprocessed rows (states: 0,1,2,3,4).
This table has over 120000 rows, but this number will grow.
Most of the rows are processed and most of them also contain a group id. Number of groups is relatively small (let's assume 20).
I would like to obtain the oldest some_date for every group. This values has to be outer joined to a on-line report (contains one row for each group).
Here is my set-up:
Tested on: 10.2.0.4 (Solaris), 10.2.0.1 (WinXp)
drop table t purge;
create table t(
id number not null primary key,
grp_id number,
state number,
some_date date,
pad char(200)
insert into t(id, grp_id, state, some_date, pad)
select level,
     trunc(dbms_random.value(0,20)),
        9,
        sysdate+dbms_random.value(1,100),
        'x'
from dual
connect by level <= 120000;
insert into t(id, grp_id, state, some_date, pad)
select level + 120000,
     trunc(dbms_random.value(0,20)),
        trunc(dbms_random.value(0,5)),
        sysdate+dbms_random.value(1,100),
        'x'
from dual
connect by level <= 2000;
commit;
exec dbms_stats.gather_table_stats(user, 'T', estimate_percent=>100, method_opt=>'FOR ALL COLUMNS SIZE 1');

BLOCKS                        : 3834I know, this could be easily solved by fast refresh on commit materialized view like this:

min(some_date),
from
t
where
state in (0,1,2,3,4)
grpup by
grp_id;+ I have to create log on (grp_id, some_date, state)
Number of rows with active state will be always relatively small. Let's assume 1000-2000.
So my another idea was to create a selective index. An index which would contain only data for rows with an active state.
Something like this:
create index fidx_active on t (
case state
    when 0 then grp_id
    when 1 then grp_id
    when 2 then grp_id
    when 3 then grp_id
    when 4 then grp_id
end,
case state
    when 0 then some_date
    when 1 then some_date
    when 2 then some_date
    when 3 then some_date
    when 4 then some_date
end) compress 1; so a tuple (group_id, some_date) is projected to tuple (null, null) when the state is not an active state and therefore it is not indexed.
We can save even more space by compressing 1st expression.
analyze index idx_grp_state_date validate structure;
select * from index_stats

Doc's snippet:
13.5.3.6 Full Scans
A full scan is available if a predicate references one of the columns in the index. The predicate does not need to be an index driver. A full scan is also available when there is no predicate, if both the following conditions are met:
All of the columns in the table referenced in the query are included in the index.
At least one of the index columns is not null.
A full scan can be used to eliminate a sort operation, because the data is ordered by the index key. It reads the blocks singly.
13.5.3.7 Fast Full Index Scans
Fast full index scans are an alternative to a full table scan when the index contains all the columns that are needed for the query, and at least one column in the index key has the NOT NULL constraint. A fast full scan accesses the data in the index itself, without accessing the table. It cannot be used to eliminate a sort operation, because the data is not ordered by the index key. It reads the entire index using multiblock reads, unlike a full index scan, and can be parallelized.
You can specify fast full index scans with the initialization parameter OPTIMIZER_FEATURES_ENABLE or the INDEX_FFS hint. Fast full index scans cannot be performed against bitmap indexes.
A fast full scan is faster than a normal full index scan in that it can use multiblock I/O and can be parallelized just like a table scan.
So the question is: Why does oracle do a full table scan?
Everything needed is in the index and one expression is not null, but index (fast) full scan is not even considered by CBO (I did a 10053 trace)

              THEN "GRP_ID" WHEN 3 THEN "GRP_ID" WHEN 4 THEN "GRP_ID" END IS NOT NULL)Let's try some minimalistic examples. Firstly with no FBI.
create index idx_grp_id on t(grp_id);
select grp_id,
       min(grp_id) min
from t
where grp_id is not null
group by grp_id;

Predicate Information (identified by operation id):
   2 - filter("GRP_ID" IS NOT NULL)This kind of output I was expected to see with FBI. Index FFS was used although grp_id has no NOT NULL constraint.
Let's try a simple FBI.
create index fidx_grp_id on t(trunc(grp_id));
select trunc(grp_id),
       min(trunc(grp_id)) min
from t
where trunc(grp_id) is not null
group by trunc(grp_id);

Predicate Information (identified by operation id):
   2 - filter(TRUNC("GRP_ID") IS NOT NULL)Again, index (fast) full scan not even considered by CBO.
I tried:
alter table t modify grp_id not null;
alter table t add constraint trunc_not_null check (trunc(grp_id) is not null);I even tried to set table hidden column (SYS_NC00008$) to NOT NULL
It has no effect, FTS is still used..
Let's try another query:
select distinct trunc(grp_id)
from t
where trunc(grp_id) is not null
| Id | Operation             | Name        | Starts | E-Rows | A-Rows |   A-Time   | Buffers |
|   1 | HASH UNIQUE          |             |      1 |     20 |     20 |00:00:00.85 |     244 |
|* 2 |   INDEX FAST FULL SCAN| FIDX_GRP_ID |      1 |    122K|    122K|00:00:00.49 |     244 |
Predicate Information (identified by operation id):
   2 - filter("T"."SYS_NC00008$" IS NOT NULL)Here the index FFS is used..
Let's try one more query, very similar to the above query:
select trunc(grp_id)
from t
where trunc(grp_id) is not null
group by trunc(grp_id)
| Id | Operation          | Name | Starts | E-Rows | A-Rows |   A-Time   | Buffers |
|   1 | HASH GROUP BY     |      |      1 |     20 |     20 |00:00:00.86 |    3841 |
|* 2 |   TABLE ACCESS FULL| T    |      1 |    122K|    122K|00:00:00.49 |    3841 |
Predicate Information (identified by operation id):
   2 - filter(TRUNC("GRP_ID") IS NOT NULL)And again no index full scan..
So my next question is:
What are the restrictions which prevent index (fast) fullscan to be used in these scenarios?
Thank you very much for your answers.

I'll start off with the caveat that i'm no Johnathan Lewis so hopefully someone will be able to come along and give you a more coherent explanation than i'm going to attempt here.
It looks like the application of the MIN function against the case statement is confusing the optimizer and disallowing the usage of your FBI. I tested this against my 11.2.0.1 instance and your query chooses the fast full scan without being nudged in the right direction.
That being said, i was able to get this to use a fast full scan on my 10 instance, but i had to jiggle the wires a bit. I modified your original query slightly, just to make it easier to do my fiddling.

ERROR BRAIN (738): Variable 0P_KEYDT not in query

Hi all,
Can anyone help with the following error that i am getting while executing a query
ERROR BRAIN (738): Variable 0P_KEYDT not in query
Regards,
P

Make sure you still have the variable in the query. You did not delete it by mistake. Error is it self says that it can not find that 0P_KEYDT in the query. YOu can also try removing and adding it again.
Sometimes the order of making variable matters when you have dependency.

Problem when using About Operator in Contains Query

I'm new to Oracle and this forums too. I have a problem when using about operator in contains query.

Hello (and welcome),
You'd be best asking this question in the Oracle Text forum, here:
Text
And by the way, it will help others to analyse if you put {noformat}{noformat} (lowercase code in curly brackets) before and after your code snippets.
Good luck!

Query not working

Dear Experts,
I am trying to execute a query provided in 'How to define and use user-defined fields' doc under How to guides for SBO 8.8 but it is giving me error "incorrect syntax near...."
The Sample query i m trying to execute, which is for adding 20 in the posting date of current active sales document (not stored in database), is : Select $[$10.0.Date] + 20
This query will be used in Due date to automatically retrieve a date which 20 days forward from the posting date.
When I am executing the above query it is give me error: SQL native client "incorrect syntax near '+' and user-defined value could be created.
Please help resolving this issue. I am using SAP Business one 8.8 SP0 PL09
Regards,
Farhan

Hi
Farhan here is ur querys u can use any one of these
i think this will solve ur prob
SELECT Docnum,DocDate,DATEADD(day,20,DocDate)
FROM ORDR
(OR)
SELECT Docnum,Convert(varchar(11),DocDate,103),Convert(varchar(11),DATEADD(Day,20,DocDate),103)
FROM ORDR

Why is this query not using the index?

check out this query:-
SELECT CUST_PO_NUMBER, HEADER_ID, ORDER_TYPE, PO_DATE
FROM TABLE1
WHERE STATUS = 'N'
and here's the explain plan:-
1
2     -------------------------------------------------------------------------------------
3     | Id | Operation | Name | Rows | Bytes | Cost (%CPU)|
4     -------------------------------------------------------------------------------------
5     | 0 | SELECT STATEMENT | | 2735K| 140M| 81036 (2)|
6     |* 1 | TABLE ACCESS FULL| TABLE1 | 2735K| 140M| 81036 (2)|
7     -------------------------------------------------------------------------------------
8
9     Predicate Information (identified by operation id):
10     ---------------------------------------------------
11
12     1 - filter("STATUS"='N')
There is already an index on this column, as is shown below:-
     INDEX_NAME INDEX_TYPE     UNIQUENESS     TABLE_NAME     COLUMN_NAME     COLUMN_POSITION
1     TABLE1_IDX2 NORMAL     NONUNIQUE     TABLE1      STATUS     1
2     TABLE1_IDX NORMAL     NONUNIQUE     TABLE1     HEADER_ID     1
So why is this query not using the index on the 'STATUS' Column?
I've already tried using optimizer hints and regathering the stats on the table, but the execution plan still remains the same, i.e. it still uses a FTS.
I have tried this command also:-
exec dbms_stats.gather_table_stats('GECS','GEPS_CS_SALES_ORDER_HEADER',method_opt=>'for all indexed columns size auto',cascade=>true,degree=>4);
inspite of this, the query is still using a full table scan.
The table has around 55 Lakh records, across 60 columns. And because of the FTS, the query is taking a long time to execute. How do i make it use the index?
Please help.

If the cardinality is really as skewed as that, you may want to look at putting a histogram on the column (sounds like it would be in order, and that you don't have one).
create table skewed_a_lot
as
   select
      case when mod(level, 1000) = 0 then 'N' else 'Y' end as Flag,
      level as col1
   from dual connect by level <= 1000000;
create index skewed_a_lot_i01 on skewed_a_lot (flag);
exec dbms_stats.gather_table_stats(user, 'SKEWED_A_LOT', cascade => true, method_opt => 'for all indexed columns size auto');Is an example.

Hi,
All the yellow and red lights will have an effect on query performance or execution. Read up on them as there are too many to explain via this forum.
There is a document on SDN on query performance. Some useful links:

Can we restrict changes made in BEx query not to resemble in Universe

Hello Gurus,
I have a question. Lets say if there is a universe created based on BEx query and if later on BEx query is changed (newly added Chars, KF's or change in names) can we restrict the changes not to resemble in Universe?
Please give me any related document or link which will be a big favor for me.
Thanks a lot for your time.

Changes in the BEx query are not reflected always automatically in your universe: Eg. if you add an new restriction or a new keyfigure. You have to maunally refresh the structure of your universe and export it again on your BOBJ server.
Some changes will be automatically available though eg. if you change the code of a customer exit variable which is already used in your BEx query, even if you do not refresh the universe.
Please keep in mind that some kind of changes in the query (removing existing key figures or characteristics) may cause error messages when you try to run your universe (assuming you did not update it).
The recommendation here is to refresh your universe when you change the underlying BEx query. If you do not want to do that then your universe may stop working.
Regards,
Stratos

Oracle ADF refresh as deferred does not execute query on page load

In the oracle ADF page I have two panel boxes. (Oracle ADF 11.1.1.4)
a) Personal information panel box with PanelFormLayout (PersonalInfoViewObj) - ReadOnly View Object
b) Address information panel box with Table (AddressInfoViewObj) - Read Only View Object
For the iterators in a) and b) I have kept refresh condition as deferred and cacheResult=false. Also in b) for af:table, I have kept contentDelivery="immediate"
When page loads it fires SQL query for a) and populate the data in Personal information panel box. However for b) it does not execute the SQL query and the data is not getting populated ( in AddressInformation panel with the tables. Please note data is there in the DATABASE......)
Becasue with the refresh as deferred it was not executing the sql query for Panel b) (panel with Table and table iterator). I have tried refresh as always and refresh ifNeeded/renderModel/prepareModel however in that case it is executing the SQL query two times (twice).
Please let me know the best way to fix this issue.

Hi,
I think you need a method in an application module to init your data.
In your AM : create a method like :
public void init(){
getViewObject().executeQuery();
}In your adfc-config.xml create a methodCall from this method and a "control flow case" from the methodCall to your page.
and keep refresh as "deferred " in your pageDef.

Why does not a query go by index but FULL TABLE SCAN

I have two tables;
table 1 has 1400 rwos and more than 30 columns , one of them is named as 'site_code' , a index was created on this column;
table 2 has more 150 rows than 20 column , this primary key is 'site_code' also.
the two tables were analysed by dbms_stats.gather_table()...
when I run the explain for the 2 sqls below:
select * from table1 where site_code='XXXXXXXXXX';
select * from table1 where site_code='XXXXXXXXXX';
certainly the oracle explain report show that 'Index scan'
but the problem raised that
I try to explain the sql
select *
from table1,table2
where 1.'site_code'=2.'site_code'
the explain report that :
select .....
FULL Table1 Scan
FULL Table2 Scan
why......

But aren't we performing such an investigation, are we? ;-)The way you wrote it, made it sound that a hint would be the solution, not just something for investigation.
select * from .. always performs full scan, so limit your query.No, select * will not always perform a full scan, that's just selecting all the columns.
A select without a where clause or that has a where clause that has low selectivity will result in full table scans.But this is what I have ment.But not what you said.

Mismatch query not working. Not sure what I did wrong.

In my query, I have created two CTE's. One pulls in the records of all people who are assigned to an audience. The other pulls in all people who are assigned to the same audience AND completed a certain course.
What I wanted to do from there, was to do a mismatch query, not to find the PEOPLE, but just the departments that were represented in the audience, but had no people in the list of those who completed the course. (In other words, say the HR Department had
three people in the audience... two completed the course, one did not. The HR Department should NOT show up in my mismatch query because some of their people completed the course. Then, say the IT Department had five people in the audience, and none of them
have completed the course. The IT Department SHOULD show up in my mismatch query. For this case, I don't care about the people who didn't complete it, just the departments where nobody did yet.)
I thought I was doing the mismatch query correctly, but I guess I must not. I will share the relevant parts of my query below (there is more to my query, but I don't think you necessarily need to see it to assist with this particular problem). (Side note:
Yes, I know the way I am doing the fiscal calendar is not ideal, but I've looked up other ways to do it, and do not understand it. Given time, I can break it down and understand it, but I am in a rush to finish this report.)

If anybody can help, I would greatly appreciate it. I'm trying to do this so I can pull these records into a final table to count the records from the other two, but then include these as a 0 count where these departments have nobody certified.
To test if this was working, I created a query using this Mismatch query instead as the main query. Instead, it seemed to give me the exact opposite. It seemed to be giving me all of the Departments (MeasurePC) where the records were represented.

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. Temporal data should
use ISO-8601 formats. Code should be in Standard SQL as much as possible and not local dialect.
This is minimal polite behavior on SQL forums. We have no sample data, so we cannot even guess.
>> In my query, I have created two CTE's. One pulls in the records [sic] of all people who are assigned to an audience. The other pulls in all people who are assigned to the same audience AND completed a certain course. <<
Please, please learn the basic terms. Rows are not records. And THEN learn what “redundancy” means so you will not write two CTEs in the future.
>> What I wanted to do from there, was to do a mismatch query, not to find the PEOPLE, but just the departments that were represented in the audience, but had no people in the list of those who completed the course. (In other words, say the HR Department

This is a Relational Division. It is one of Dr. Codd's original 8 operations.
We do not use the Sybase CURRENT_TIMESTAMP any more. We have DATE data types tody, rtoo. We never tibble in good code; it is a design flaw that used meta-data affixes like “tbl” in schema object _names, PK in column _names, etc. We do not have repeated groups
like “org_code_2”; we do not use arrays in RDBMS. Why is your data so screwed up you have use
CASE
WHEN org_code2 LIKE 'US%' THEN 'US'
WHEN org_code2 LIKE 'CA%' THEN 'CA' END
to clean it up in a query; the DDL should have prevented this problem.
Why are you doing calendar computing in your query? Where is the Calendar table?
“Users.id = UsrOrgs.user_id” says that you have magic, generic “id” that can change its name from table to table. Likewise, a generic, magic “code”, etc. What might be even worse is that totally different data elements have the same name! “Automobiles, squids
and Lady Gaga” programming is not RDBMS.
You have never heard of ISO-11179 and data modeling?
Here is a skeleton for fiscal calendar table to replace your current row by row temporal math:
CREATE TABLE Calendar
(cal_date DATE NOT NULL PRIMARY KEY,
fiscal_month CHAR(10) NOT NULL,
INSERT INTO Calendar
VALUES
('2014-10-01', '2015-01-00', ..),
('2014-09-30', '2015-12-00', ..),
You can use a spread sheet and a text edit to fill in the table for 50 or 100 years.
I like the MySQL convention of using double zeroes for months and years, That is 'yyyy-mm-00' for a month within a year and 'yyyy-00-00' for the whole year. The advantages are that it will sort with the ISO-8601 data format required by Standard SQL and it is
language independent. The pattern for validation is '[12][0-9][0-9][0-9]-00-00' and '[12][0-9][0-9][0-9]-[01][0-9]-00'
