Oracle Text multi column index based query returns no rows

Hello

I have a MAH_KERESES_MV table with 3 columns OBJEKTUM_NEV, KERESES_SZOVEG_1, KERESES_SZOVEG_2. I create the following Oracle multi column text index:

ctx_ddl.create_preference exec ('MAH_SEARCH', 'MULTI_COLUMN_DATASTORE');
ctx_ddl.set_attribute exec ('MAH_SEARCH', 'COLUMNS', 'OBJEKTUM_NEV, KERESES_SZOVEG_1, KERESES_SZOVEG_2');

create index MAX_KERES_CTX on MAH_KERESES_MV (OBJEKTUM_NEV)
indexType is ctxsys.context
parameters ("DATASTORE MAH_SEARCH");
But the query returns no rows, although if I make the query with the 'like' operator, and then I get the results as expected:

SELECT id, OBJEKTUM_NEV
OF MAH_KERESES_MV
WHERE CONTAINS (OBJEKTUM_NEV, "C") > 0;

Can some body please help? TIA,

Tamas

You can do it in Oracle Text, well it is not necessarily desirable.

You can search the

WHERE CONTAINS(OBJEKTUM_NEV, '%C%')>0;

And it will probably work in a simple test. However, using a leader like this wildcard prevents them the index on the table "list of words" used, so such a request can be very slow on a large system.
You can improve this by using SUBSTRING_INDEX, but making your much bigger index. And you could always hit the 'expansions too' problem if %C % expansion is more than about 15,000 words (depending on version and different settings).

Also be aware of differences in case - %C % will match 'fact' or 'FACT', as part of a CONTAINS, but not part of a TYPE.

If a view object query returns no rows, can the vacuum to be tested at all?

All those who know or have also experienced:

I guess that the answer should be Yes, but I tried anyway, I still didn't worked. Here is the code (it's a method behind a command button, a bean of support (I use JDeveloper 10.1.3.4).) In the code, LoggedInStudent is the name of a view object; ZBLCModule is the name of the application module):

    public String commandButton1_action() {
        FacesContext fc = FacesContext.getCurrentInstance();
        ValueBinding vb = fc.getApplication().createValueBinding("#{data}");
        BindingContext bc = (BindingContext)vb.getValue(fc);
        DCDataControl dc = bc.findDataControl("ZBLCModuleDataControl");
        ApplicationModule am = (ApplicationModule)dc.getDataProvider();
        ZBLCModuleImpl zblcam = (ZBLCModuleImpl)am;
        LoggedInStudentImpl studentsFound = (LoggedInStudentImpl)zblcam.getLoggedInStudent();
        
        String navCase = null;
        
        // Test (1): if the view cache is empty; always bombs up the application if it IS empty:
        if(studentsFound.getAllRowsInRange().length == 0) {
            navCase = "userNotFound";
        // (2) The following three tests gets to run only when the cache is not empty; they work fine.
        } else if (((Number)studentsFound.first().getAttribute("HoursAttm")).floatValue() == 0.0) {
            navCase = "noHours";
        } else if (((Number)studentsFound.first().getAttribute("Balance")).floatValue() > 0.0) {
            navCase = "notZero";
        } else if (!(studentsFound.first().getAttribute("Validated").equals(" "))) {
            navCase = "validated";
        } else {
            navCase = "zeroBal";
        }
        return navCase;
    }

When the view object query returns a line, the whole of the application works without error. When the query returns no rows, test (1) always bombs toward the top of the application, prompting a Houston-30003 error.

(1) test, I tried the following:

  if (studentsFound.getAllRowsInRange().length == 0)
  if (studentsFound.first() == null)
  if (studentsFound.getEstimatedRowCount() == 0)
  if (studentsFound.isDead()) //I do not know what isDead() does; just tried desperately.
  if (studentsFound.equals(null))
  if (studentsFound.getCurrentRow() == null)

With each of these events, I got an error of Houston-30003. It does not matter what looks like the conditional test; It is important only when the objects from view cache is empty. If the view cache is not empty, everything, including the test (1), works very well. And when the cache is empty is not because of the failure of the connection to the database, but because the student is not in the data table and line are for the student.

It is a requirement of the company to do something when the view object query returns no rows. Can it be tested at all? How?

Or is there something wrong in the first lines in the method before the {color: green} String navCase = null; {color} line?

Thank you very much for your help!

Hello

What you have done, is to get a handle to the object that CAN execute queries to the database.
However, you do not query the database.

Just add:

  LoggedInStudentImpl studentsFound = (LoggedInStudentImpl)zblcam.getLoggedInStudent();
  //New line
  studentsFound.executeQuery();

The code that Shay has given you is when you do not have a request for all module, but since you are talking about a command etc button I guess that the module of the application is already active.
The line I gave you should be enough to make it work.

I'd be careful with the

studentsFound.hasNext();

I suggest to use estimatedRowCount();

Oracle Text, multi_column_datastore describe index
Referring to the Re: Oracle Text, ctxsys.context problem with column number

TOAD or SQL Navigator, you can click on an object any (such as a table, index) and click on the "script" tab where the code is generated to create.

Assuming that I am a person who sees the index for the first time where/how I can find multi_columns/settings with which the index has been created?

For example:
```
exec ctx_ddl.drop_preference( 'myds' );
exec ctx_ddl.create_preference( 'myds', 'MULTI_COLUMN_DATASTORE' );
exec ctx_ddl.set_attribute( 'myds', 'COLUMNS', 'item_barcode, item_title, item_subtitle' );
CREATE INDEX i_index_test
   ON item (item_title)
   INDEXTYPE IS ctxsys.context
   PARAMETERS ( 'datastore myds' );
```
And script says:
```
CREATE INDEX PLSQL.I_INDEX_TEST ON PLSQL.ITEM
(ITEM_TITLE)
INDEXTYPE IS CTXSYS.CONTEXT
PARAMETERS('datastore myds')
NOPARALLEL;
```
Where can I find datastore "myds"?
You can use ctx_report to get information about an index.

I use it for SQL * more like this:
```
set pagesize 0
set heading off
set trimspool on
set long 500000

spool index.sql

select ctx_report.create_index_script('MyIndexName') from dual;

spool off
```
The only thing it will not give you is the source for all of the procedures used in the user_datastore. You can get to user_sources.

Stupid old backpacker (me) cannot understand why this query returns 1 row

Hi all

In reference to {: identifier of the thread = 2456973}, why do

select sum(count(decode(job, 'CLERK', 1, null))) CLERKS
, sum(count(decode(job, 'SALESMAN', 1, null))) SALESMANS
from emp group by job;

only 1 rank and not 1 for each task? In fact, I had to test it myself to believe.

It returns the data as if the query were

select sum(CLERKS), sum(SALESMANS)
from (select count(decode(job, 'CLERK', 1, null)) CLERKS, count(decode(job, 'SALESMAN', 1, null)) SALESMANS
         from emp group by job)

Using only a single aggregate (count or sum) returns 1 row per job, as expected

Exactly the point ;-)

It seems that Oracle actually do, a group of 'double' in the same operation.
Attend plans to explain in this example:

SQL> select count(decode(job, 'CLERK', 1, null)) CLERKS
  2       , count(decode(job, 'SALESMAN', 1, null)) SALESMANS

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

There are GROUP BY hash and SORT GLOBAL times.

It is really unnecessary to an aggregate on an aggregate - if two aggregates are used "in the same group level.
Sum() aggregates are used on an already aggregated value, so it doesn't look like Oracle which actually cures like 'first do the internal aggregate using the group specified by and then do the external aggregation on the result with any group.'

Look at this example where I combine aggregates "double" with "single" aggregates:

SQL> select sum(count(decode(job, 'CLERK', 1, null))) CLERKS
  2       , sum(count(decode(job, 'SALESMAN', 1, null))) SALESMANS
  3       , count(decode(job, 'SALESMAN', 1, null)) SALESMANS2
  4       , count(*) COUNTS

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

When you mix "doubles" and "single" aggregates, Oracle decides that unique aggregates belong to the 'outer' aggregation
SALESMAN2 did a count on the aggregated work column which is the result of the 'internal' group by - so only 1.
The count (*) is also the result of the aggregation of the 'internal '.

I don't know if it's documented or if it is an 'effect' of internal code used for GROUPING SETS or the internal code used to enable the analytical functions like this:

SQL> select count(decode(job, 'CLERK', 1, null)) CLERKS
  2       , count(decode(job, 'SALESMAN', 1, null)) SALESMANS
  3       , sum(count(decode(job, 'CLERK', 1, null))) over () CLERKS2
  4       , sum(count(decode(job, 'SALESMAN', 1, null))) over () SALESMANS2

Personally, I think that I would have preferred if Oracle has raised an error on this "double aggregation" and therefore require me to write this way (if it's the result I wanted):

select sum(CLERKS), sum(SALESMANS)
from (select count(decode(job, 'CLERK', 1, null)) CLERKS, count(decode(job, 'SALESMAN', 1, null)) SALESMANS
         from emp group by job)

I don't really see a good use case for aggregations of 'double'-, but rather that he could give you undetected bugs in your code, if you happen to do double aggregation without noticing.

Interesting thing to know ;-)

Attributes XML makes my query returns no rows

Hi all

I have a strange problem.

I ask an XML, but the attributes in one of the tags my query will return no rows. If I delete the attributes, the query works as expected.

The XML code is below; This is the Report tag attributes that cause problems:

<result errorCode="0">
     <return>
          <Report
               xsi:schemaLocation="Items_x0020_status_x0020_information http://******-****/ReportServer?%2FReports%2FContent%20Producer%20Reports%2FItems%20status%20information&amp;rs%3AFormat=xml&amp;rc%3ASchema=True"
               Name="Items status information" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
               xmlns="Items_x0020_status_x0020_information">
               <Tablix1>
                    <Details_Collection>
                         <Details ItemId="914P7" Username="test" user_role="IT"
                              first_name="Barry" last_name="Donovan" organisation=""
                              content_format="On_Screen" modified_date="26/05/2011 13:16:49"
                              item_status="Draft" status_date="" component_name="" demand="" />
                    </Details_Collection>
               </Tablix1>
          </Report>
     </return>
</result>

My query is:

     select
            a.item_id
           ,a.username
           ,a.user_role
           ,a.first_name
           ,a.last_name
           ,a.supplier_id
           ,a.format
           ,a.modified_date
           ,a.item_status
           ,a.completion_date
           ,a.component_code

         from   dual
               ,xmltable
                ('/result/return/Report/Tablix1/Details_Collection/Details'
                   passing p_xml
                   columns
                      item_id         varchar2(1000) path '@ItemId'
                     ,username        varchar2(1000) path '@Username'
                     ,user_role       varchar2(1000) path '@user_role'
                     ,first_name      varchar2(1000) path '@first_name'
                     ,last_name       varchar2(1000) path '@last_name'
                     ,supplier_id     varchar2(1000) path '@organisation'
                     ,format          varchar2(1000) path '@content_format'
                     ,modified_date   varchar2(1000) path '@modified_date'
                     ,item_status     varchar2(1000) path '@item_status'
                     ,completion_date varchar2(1000) path '@status_date'
                     ,component_code  varchar2(1000) path '@demand'
                ) a;

I tried to strip the attributes to the tag, which works, but some XML I look back are large enough (number of records), so that cause problems in itself. I would rather deal with it and don't mess with the XML itself if possible.

Any help would be much appreciated!

Thank you much in advance.

You have stated that in the request too:

SQL query returning no rows, please help!
I have a table that contains the user checks for a specific procedures alongwith the date stamp. Now, I want the list of all procedures that are not accessible by users in the last 6 months. Or, all of the procedures that have not been used/accessible during the last 6 months.

That's what I'm trying, but is does not return all rows:

Hello

NOT IN never returns TRUE if the subquery returns NULL values. If proc_name doesn't have a NOT NULL constraint, change the subquery to
```
WHERE        proc_name     NOT IN ( SELECT  proc_name

Registration of image data to text - multi-column file

Hello

I'm currently grabbing images using functions IMAQ and am averaging of each image through the columns using IMAQ LinearAverages.vi. I am currently saving these values (IE a size of profile line 1: n) to a text file. However, I have a large amount of images (M) to capture, so I would like to display each image line profile data to an individual column.

At the moment the text file captures all of the data, but in a single column, not very useful for the purposes of post-processing. Can someone suggest a nice way to do this? Records in a spreadsheet file better?

I would appreciate any advice.

Kind regards

Seems to me that if the pid is different.
Select * from where a pid = "ACT714";<-- no="">
Select * from b where pid = "ACT714";<-- trailing="">

Try
Select count (*) of a, b
where trim (a.pid) = trim (b.pid);

If it works, you might want to consider how you store data, if they are supposed to be equal.

Check also if you compare with the data type varchar2, char data type.
I generally avoid the reasons char data type.

SQL query returns no row vs. multiple lines

Hello

I am trying to get the result of a simple sql query,
If there is no row returned, he would have "No. ROWS" in the result set.
Other wise all the rows containing data is necessary.

Let me know how this could be achieved. Under query works for the latter and not first case as mentioned below

OUTPUT

+ (box 1) when we use B_ID = 123456 +.

IDS
-----
'NO LINE '.

+ (box 2) when we use B_ID = 12345 +.
IDS
-----
1 11112345
2 22212345

create table TEMP_AAA
(
  A_ID VARCHAR2(10),
  B_ID VARCHAR2(10)
)

INSERT INTO TEMP_AAA(A_ID,B_ID) VALUES('111','12345');
INSERT INTO TEMP_AAA(A_ID,B_ID) VALUES('222','12345');
INSERT INTO TEMP_AAA(A_ID,B_ID) VALUES('333','12000');
INSERT INTO TEMP_AAA(A_ID,B_ID) VALUES('444','10000');

WITH 
MATCH_ROWS AS
(
       SELECT A_ID||B_ID IDS FROM TEMP_AAA WHERE B_ID=12345
),

MATCH_ROW_COUNT AS
(
       SELECT COUNT(1) AS COUNTS FROM MATCH_ROWS
),

PROCESSED_ROWS AS
(
       SELECT
             CASE WHEN COUNTS = 0
                  THEN 
                   (SELECT NVL((SELECT IDS FROM TEMP_AAA WHERE B_ID=12345),'NO ROWS') IDS FROM DUAL)
                  ELSE
                   MATCH_ROWS.IDS
             END IDS     
        FROM MATCH_ROWS,MATCH_ROW_COUNT
)

SELECT * FROM PROCESSED_ROWS;

Hello

I think you want to put this on a report or something. I have what would be easier to do this logic there. But if you want that this is possible.
Like this

with
temp_aaa as
(select '111' a_id ,'12345' b_id from dual union all
select '222'      ,'12345'  from dual union all
select '333'      ,'12000'  from dual union all
select '444'      ,'10000'  from dual
)
, wanted_rows as
( select  '123456' B_ID from dual)
select
  temp_aaa.A_ID || temp_aaa.B_ID IDS 

from
  temp_aaa
  ,wanted_rows
where
  temp_aaa.b_id = wanted_rows.b_id
union all
select
  'NO ROWS'
FROM
  DUAL
WHERE
  (SELECT COUNT(*) FROM TEMP_AAA, wanted_rows WHERE TEMP_AAA.B_ID = wanted_rows.B_ID) = 0

In addition, you mix var and number of always use the same type or convert explicitly (to_number or to_char)

WITH
MATCH_ROWS AS
(
       SELECT A_ID||B_ID IDS FROM TEMP_AAA WHERE      B_ID           =12345
--                                                    varchar2(10)   number
),
...

And again in the

                  THEN
                   (SELECT NVL((SELECT IDS FROM TEMP_AAA WHERE B_ID           =12345),'NO ROWS') IDS FROM DUAL)
--                                                             varchar2(10)   number

Kind regards

Export query returns no rows

Dear guy,
I jam with this problem for 2 days and have you guy help me to check it out. Here's my parfile
TABLES IS UMARKETADM. TRANS_DATA
CONTENT = DATA_ONLY
EXCLUDE = STATISTICS
QUERY = UMARKETADM. TRANS_DATA: "WHERE transid in (select id from umarketadm.trans t where t.last_modified > to_date (5 January 2014 00:00:00 ',' DD/MM/YYYY hh24:mi:ss') and t.state in (2.6))" "
DUMPFILE = SHARED_DIR:Demand.dmp
Network_link = remote_db
and the result is:
. . exported "UMARKETADM." "" TRANS_DATA ". 6,398 KB 0 rows
Main table 'SYSTEM '. "" SYS_EXPORT_TABLE_01 "properly load/unloaded
But when I check in, select the table:
Select count (*) in umarketadm.trans_data
where transid in (select id from umarketadm.trans t where t.last_modified > to_date (5 January 2014 00:00:00 ',' dd/mm/yyyy hh24:mi:ss') and t.state in (2.6));

then it results in: 1271258 lines
Yes, is there some things wrong with my parfile?
So thank you and best regards
Ch

Hello

I think that maybe it's a quirk of how works on network lnk datapump. I think the memory some of the rferences becomes 'local' rather than distance.

You can try?

TABLES IS UMARKETADM. TRANS_DATA

CONTENT = DATA_ONLY

EXCLUDE = STATISTICS

QUERY = UMARKETADM. TRANS_DATA: "WHERE transid in (select id from umarketadm.trans@remote_db t where t.last_modified > to_date (5 January 2014 00:00:00 ',' DD/MM/YYYY hh24:mi:ss') and t.state in (2.6))" "

DUMPFILE = SHARED_DIR:Demand.dmp

Network_link = remote_db

See you soon,.
