• LEFTOUTER join querry which gives bad result

  Hello

  I have tables like below.when I perform a left outer join issue IDs and startdate he gives invalid results.when I write in request

  It does not correct result because there is no data for 16 jan. It should give no results. But it shows all records. How do I solve this problem

  SQL:

  Select a.id, a.date, b.val, a.tot, b.net, b.cre

  FROM table1 a

  join table2 b left

  "on a.id = b.id and a.date = b. and a.date ='02-Feb-2014."

  In the tables below contains no data for the month of February but still im getting the incorrect data. He must not returnany files right?

  Table1:

  ID	Date	Val	tot
  1	January 1, 13	1	9
  2	2 January 13	3	8
  3	3 January 13	4	7
  4	January 4, 13	5	6
  5	5 January 13	6	5

  Table2:

  ID	Date	NET	CRE
  1	January 1, 13	1	9
  2	13 January 13	3	8
  3	3 January 13	4	7
  4	January 4, 13	5	6
  5	5 January 13	6	5

  "It should not returnany files right?

  Wrong, there is no where clause so it should return all the records in a padded with NULL values for b.

• view inline values, which gives bad result...

  I saw a123 table with data below...

  
  

  	GRANT	AMOUNT	DRCR
  1	1234	1000	D
  2	1234	5000	C
  3	12345	2000	C

  Now I want below o/p of the table of the a123

  12345	-5000

  To do this, I wrote below the query but its appropriate result not give...

  Select grant, credit-debit balance of)

  Select grant, sum (debit) Debit, sum (credit) credit of)

  Select grant,

  Drcr case when 'C' THEN amount *-1 Else NULL END in the form of credit.

  Drcr case when had ' then amount end otherwise null flow

  from a123)

  Grant group);

  top query results are below...

  	GRANT	BALANCE
  1	1234	6000
  2	12345	9000

  Please help me on this thanks...

  Pretty obvious what is wrong:

  you convert credit figures in negative numbers with the case statement

  If you have

  1	1234	1000	D
  2	1234	-5000	C
  3	12345	-2000	C
  4	12345	7000	D

  and after that you are subtracting these figures of your throughput numbers.

  Therefore, do not convert negative credits before subtracting the or if you want to make negativ, then you must add them.

  1000 + 5000 =-4000

  1000-5000 = 6000

• Oracle text index does not return the expected results.

  Hello
  
  My project requires a generic search on 5 different columns and all the VARCHAR2 data type.
  As performance is very slow with AS % search, I try to use for the multi_column_datastore that is recommended for this.
  
  Here's what I did.
  
  1 - Create table.

  CREATE TABLE BILLING_SCHEMA.NAMES_TABLE ( 
      ID                  NUMBER(9,0) NOT NULL,
      ENTITY_NUMBER         VARCHAR2(30) NOT NULL,
      GIVEN_NAMES         VARCHAR2(50) NULL,
      SURNAME             VARCHAR2(30) NULL,
      ORGANISATION_NAME     VARCHAR2(60) NULL,
      DISPLAY_NAME        VARCHAR2(100) NULL 
      )
  /
  
   

  My search must be made on the columns ENTITY_NUMBER, GIVEN_NAMES, surname, ORGANISATION_NAME and DISPLAY_NAME.
  
  2. - insert values into the table

  INSERT INTO NAMES_TABLE VALUES(1, 'GH', NULL, NULL, NULL, 'GROUP OF HOSPITAL')
  /
  INSERT INTO NAMES_TABLE VALUES(2, 'DH', NULL, NULL, NULL, 'DEPARTMENT OF HEALTH')
  /
  INSERT INTO NAMES_TABLE VALUES(3, 'REC', NULL, NULL, NULL, 'DEBTOR FOR RECEIPTS')
  /
  INSERT INTO NAMES_TABLE VALUES(4, 'UN_REC', NULL, NULL, NULL, 'DEBTOR FOR UNMATCHED RECEIPTS')
  /
  INSERT INTO NAMES_TABLE VALUES(5, 'SAM_FUND', NULL, NULL, NULL, 'THE S FUND')
  /
  
   

  3 - create context multi_column_datastore index
  

  BEGIN
  CTX_DDL.CREATE_PREFERENCE('NAMES_TABLE_MULTI', 'MULTI_COLUMN_DATASTORE');
  CTX_DDL.SET_ATTRIBUTE('NAMES_TABLE_MULTI', 'COLUMNS', 'ENTITY_NUMBER, GIVEN_NAMES, SURNAME, ORGANISATION_NAME, DISPLAY_NAME');
  END;
  
  CREATE INDEX NAMES_TABLE_IDX
  ON NAMES_TABLE(ENTITY_NUMBER)
  INDEXTYPE IS   CTXSYS.CONTEXT
  PARAMETERS ('DATASTORE NAMES_TABLE_MULTI')
  
   

  4 - create the trigger that should update the column ENTITY_NUMBER if everything is inserted/updated

  CREATE OR REPLACE TRIGGER NAMES_TABLE_TRIGGER
  BEFORE INSERT OR UPDATE OF GIVEN_NAMES, SURNAME, ORGANISATION_NAME, DISPLAY_NAME  ON NAMES_TABLE
  FOR EACH ROW
  BEGIN
    :NEW.ENTITY_NUMBER := :NEW.ENTITY_NUMBER;
  END
   

  5. the search query
  

  SELECT *
  FROM NAMES_TABLE
  WHERE  CONTAINS(ENTITY_NUMBER,'%TH%') > 0
   

  I am so very confused here because the result returned is only
  

  ID     ENTITY_NUMBER     GIVEN_NAMES     SURNAME     ORGANISATION_NAME     DISPLAY_NAME         
   2      DH                  (null)        (null)         (null)          DEPARTMENT OF HEALTH 
   

  When I wait for him that the 5th inserted record is returned too as it contains "THE S FUND" that begins with "TH".
  
  When I use the search string '% %' and %, no results are returned, although I expect at least two records in each case.
  
  I would appreciate help with this.
  
  Thanks in advance,
  Marilyn

• Find text in secure file gives bad result

  I'm usung Adobe Reader 10.1.4 with Windows 7 32 bit.  When I try to find the text, I get a wrong result if the PDF is secured.  I get the correct result in a file that is not guaranteed.  The same search for the secure file works on another PC also running Adobe Reader 10 and Windows 7.  I uninstalled Adobe Reader and re-installed.  Any ideas on what could cause this?

  After much research of all options of security in programs I thought likely to affect Adobe Reader, I reached nothing a lot of expletives later, I found the solution

  Open Adobe Reader > edit > Preferences > search, click on "empty Cache Contents.

  Everything works again!

• Query to find columns (in relation FK) which gives bad child result...

  I need to find all the columns in a Parent child table. I wrote the below query to do this.

• (9.2.0.5.0) 9i - Oracle Text - Indexing of Oracle files on the FTP server

  I'm using Oracle 9i (9.2.0.5.0) and I cannot upgrade to a newer version of Oracle DB.
  I am new to this technology, and I have not tried it yet myself.
  
  I was reading some articles, documents or references on Oracle text technology and I find that Oracle text must be able to create an index of context on files residing on the FTP server.
  I also discovered that, for this purpose, a 'URL_DATASTORE' should be used.
  
  I'd be happy if someone can answer my question before I decide to start using this technology:
  Is there a limitation that I should be informed when creating index of context on files residing on the FTP server? (file size limit, limitation of the types of files supported)
  -In the creation of the index process are the files indexed, downloaded and copied in the Oracle database permanently or only temporarily until the index is created?
  -Everything is of incremental indexing (when I add new files in the data store that I don't have to rebuild the entire index)?
  There there a formula between context index disk size and the disk size indexed files?
  
  Kind regards
  
  Michal

  Is there a limitation that I should be informed when creating index of context on files residing on the FTP server? (file size limit, limitation of the types of files supported)
  Maximum file size is configurable up to 2 GB. No limitation on the file type from the data store itself, but if you want to process binary file list filter suported file formats will apply (see the appendix in the Administrator's guide)

  -In the creation of the index process are the files indexed, downloaded and copied in the Oracle database permanently or only temporarily until the index is created?
  That temporarily

  -Everything is of incremental indexing (when I add new files in the data store that I don't have to rebuild the entire index)?
  The question, I suspect that you see this as a robot - you expect to provide the address of an FTP site and have it look for all documents. This isn't how it works. Instead, you must place all of the URLS in a table, and text will index these URLS (and only these URLs)

  If new files are added, you must reorganize somehow having the new lines added to your table. Then the text will do an incremental update, it will not have to rebuild the entire index.

  There there a formula between context index disk size and the disk size indexed files?
  It varies a lot depending on the data types and indexing of selected options, but a typical result is that the index will be 40% of the total size of the file. However, if the documents are in the format (for example, Word, PDF) the percentage will be much smaller.

  At first glance, I see that you have a wrapper

• SDO_FILTER which gives weird results

  Hi people,
  
  Not sure if this is a bug or maybe I'm just not see something simple. On 11.2.0.4. I have an area of the area of interest and a line next door representing a piece of water, the two geometries validate the tolerance of 5 centimeters.
  http://www.dziemiela.com/june27.PNG
  The box is more than a mile away from the stream. The flow is relatively small and its MBR is no where close to touch the area. However, according to SDO_FILTER, two geometries are TRUE. I'm puzzled. So I wrote the mess for anyone wishing to give it a shot. I'll be back
  
  Streamy is valid? TRUE
  Véronique is valid? TRUE
  Basic SDO_GEOM. RELATE? DISJOINT
  Distance between 1795.19857225394 M
  MIL SDO_GEOM. RELATE? DISJOINT
  Distance between 1794.97512096382 M
  SDO_RELATE County 0
  SDO_FILTER County 1
  
  If two geometries are distance of 1.7 km and their members are distance of 1.7 km. I would like to say very clearly that these things shouldn't interact. Right? However, filter gives TRUE. Am I a something Klutz?
  
  Thank you
  Paul

  Hi Paul,.

  For geodetic geometry, R-tree index are in 3D. For example, you can see:

  SQL> select sdo_index_name, SDO_ROOT_MBR from user_sdo_index_metadata;
  
  SDO_INDEX_NAME
  --------------------------------
  SDO_ROOT_MBR(SDO_GTYPE, SDO_SRID, SDO_POINT(X, Y, Z), SDO_ELEM_INFO, SDO_ORDINAT
  --------------------------------------------------------------------------------
  STREAMY_SPX
  SDO_GEOMETRY(3008, NULL, NULL, SDO_ELEM_INFO_ARRAY(1, 1007, 3), SDO_ORDINATE_ARR
  AY(.16636, -.759816, .628418, .166646, -.759754, .628538))
  

  sdo_boxy is converted to:
  SDO_GEOMETRY (3008, NULL, NULL, SDO_ELEM_INFO_ARRAY (1, 1007, 3), SDO_ORDINATE_ARR)
  AY (. 166589,-. 759798,.628364,.169393,-. 757698,.630331))

  If the two MBR or minimum limit boxes (MBBs) intersect.

  ... I understand your answer, but then, what are the criteria used internally in this case (since both records have the same date)) to sort the records

  What is the order when you do not have an ORDER BY clause at all? Oracle output lines in whatever order it finds convenient, depending on how the lines are read, what treatment is done for lines and other factors. There is no guarantee that the lines will be in a particular order. If you run the same exact query again, without any change to the table, you can get a different order.

  It goes the same for lines where there is equality in ORDER BY expressions. If the entire ORDER BY clause is "ORDER BY action_date", then you can be certain that the lines with a lower action_date will come before lines with a higher action_date, but, if 2 or more rows have exactly the same action_date, to the second, so they could appear together in an order any. If you rerun the query, without chaniging table, the related rows may appear together in a different order.

  If you want the output in a particular order, to use an ORDER BY clause to mean that order.

• Key combinations give bad result?

  Hello

  I recently bought the HP Pavilion 15-e007tu from an ecomerce store. I just found out that when I press on "shift + 2" for typing ' @' he doesn't but double quotation ("") is a combination. "." In the same way when I press the combination 'shift + single quote', it seems "@" instead of double quotes.

  The keys work incorrectly, interchangeably, except these two the rest work correctly.

  How can I solve this problem? Is this a glitch or a large?

  Thanks for all your help!

  Yes, but the same thing applies to a laptop computer with Windows installed.

  Keyboards are mapped in languages and they may differ by a few keystrokes. A selection of English UK differs from English in the United States or International.

• Count on column month function gives bad result

  Hello

  I'm on OBIEE 11.1.1.7.150120.

  I used the count on the column for the month function and instead of getting 12 as the answer I get 365. (I used a filter on the column year to restrict to one year)

  How could it happen?

  Any help would be appreciated.

  A count on your back 1661600 fact table is not strange because it is normal to have a ton of lines (zero, one or more for each value of your dimensions).

  If you look at the physical SQL what is it? 365 days is because of 1 line of time Sun has multiple matches on your fact table or is dim because your time is at the level of the day (again 365 is really a strange number: exactly the number of days in the year...).

  But the distinct count is your solution, because as soon as your will a request using your time and dimension of any other table with County you will count the number of lines and not the number of months.

• Satellite L10 and keyboard:-shift key gives wrong results

  Hello, Alan

  It will be nice if you can give us more information. What specific keyboard of the country you have? What you want to do exactly? Give us a few examples please.

• bad results for the search for context on the empty element tags

  I use Oracle DBMS 11.1 and 11.2 and created an index on an XML column context (article group: PATH_SECTION_GROUP).
  When you enter a query like
  
  SELECT count (*) FROM my_table t WHERE contains (t.co_xml,'hasPath(/tag1/tag2)') > 0
  
  I get bad results if tag2 is an empty element tag (< tag2 / >) that appears somewhere in the
  XML instance, but is NOT directly under tag1.
  
  For example, the following XML instance is (but shouldn't!):
  
  < a >
  blah blah < tag3 > < tag1 > < / tag3 > < / tag1 >
  blah < tag4 > < tag2 / > < / tag4 >
  < /a >
  
  This seems to happen only for the empty element tags. Is this a known bug and does anyone know of a workaround?
  
  Thank you in advance for your help!

  Like you, I've been looking in the wrong places, bug of thought, rather than documented behavior. Finally, I came across the following excerpt from the next section of the documentation on haspath in Oracle text reference.

  http://download.Oracle.com/docs/CD/B28359_01/text.111/b28304/cqoper.htm#i997393

  Limits

  Because of the way in which XML data section are saved, false match may appear with XML sections that are completely empty as follows:

  A query of HASPATH(A/B/E) or HASPATH(A/D/C) falsely corresponds to this document. This type of fake correspondent can be avoided by inserting some text between the empty tags.

• Oracle text index - unexpected behavior

  We have a SEARCH_TABLE (in Oracle 12.1.0.1.0) with a couple of files (actually about 10,000,000 records):

  ID ADDRESS

  1     | WIMPEL | 57. 9733BK | GRONINGEN |

  2     | JOHAN WILSSTRAAT | 7 ||| 1333PV | ALMERE |

  3     | ABRAHAM KUYPERHOF | 10. 8091XN | WEZEP |

  
  

  To support research on the table addresses, we apply an Oracle text index:

  create index ST_CTX1 on SEARCH_TABLE (address)

  indexType is ctxsys.context

  parameters ("DATASTORE CTXSYS. DEFAULT_DATASTORE');

  
  

  Our research focuses on whole words (without jokers). When searching through the data, it usually comes back with the correct results.

  
  

  SELECT THE ID

  OF SEARCH_TABLE

  WHERE CONTAINS (ADDRESS, 'GRÖNING') > 0

  ;

  Returns nothing, that is correct. Once the search argument 'GRÖNING' is replaced by 'GRONINGEN', ID 1 is correctly selected. According to this behavior, the following query returns no records:

  SELECT THE ID

  OF SEARCH_TABLE

  WHERE CONTAINS (ADDRESS, 'ABR & KUYPERHOF') > 0

  ;

  
  

  Surprisingly, however, the following query returns record ID 3:

  SELECT THE ID

  OF SEARCH_TABLE

  WHERE CONTAINS (ADDRESS, ' A & KUYPERHOF ') > 0

  ;

  (Even if data does not contain the complete word 'A'). This unexpected behavior only seems to occur when you use "A" as the initial character.

  The following query (with the search starting with the character 'J' argument) returns no data. Which is the expected behavior.

  SELECT the ID

  OF SEARCH_TABLE

  WHERE CONTAINS (ADDRESS, 'J & WILSSTRAAT') > 0

  ;

  Anyone has an idea why the text index returns with A situations? Any ideas on how to solve this problem are appreciated.

  According to the list of empty words by default in 11.2, the letters a, d, i, s, and t are listed, so would be removed from the wanted list of tokens.  Thus, 'A & WILSSTRAAT' becomes '& WILSTRAAT' and search text line with a single word.  'j' is not an empty word, so it is considered to be a token is valid and is not in your tables.  Look in CTXSYS. CTX_STOPWORDS to see what you have.
