How do already created Index status valid of UNUSABLE

Dear experts,

I use a user called EMILANINVMASTER, and it contains a table and index.

in this user, programmer has created two index on name of the table called AWSCITYMASTER. both indexes spent in unusable state.

Herewith, I mentioned an index called IDX_AWACSCITYMASTER_OSID for an example

  • How to create indexes on the column xmtype

    Hello

    I have a table as follows

    CREATE TABLE T_TEST_XML (ID_PROCESSUS NUMBER, TXT_XML XMLTYPE);


    I query the table above very frequently with the query

    SELECT * FROM TXS T_TEST_XML WHERE EXISTSNODE (TXS. TXT_XML, '/ order [status = "PEN"]') = 1


    How to create function function index on the TXT_XML column for the xpath expression/order [status = "PEN"]' to improve the query performance?

    Thank you

    In fact if you are limited to the use of older software

    1 consider to define an XML schema and store XML using storage relational object.

    or

    2. If you need to store XML as CLOB to create the index on extractValue(), rather than existsNode() and provide the underlying value at the SQL level rather than the XPATH level.

    SQL> DROP TABLE T_TEST_XML
  2  /

Table dropped.

SQL> CREATE TABLE T_TEST_XML (PROCESS_ID NUMBER, TXT_XML XMLTYPE)
  2  /

Table created.

SQL> create INDEX T_TEXT_XML_IDX on T_TEST_XML( extractValue(TXT_XML,'/order/status'))

  • How to create indexes of service according to

    Hi all

    I already post a thread associated with this thread, but there is little difference in the two threads.

    I had a query as below:

    Select concept_Un, raw_concept_a, relation_name, concept_b, discovered_relations raw_concept_b, where lower (concept_a) like '% of consumers' and lower (concept_a) like '% confidence % ';


    This query taking too long to run and its high rating.

    cost and execution time: 1155K and 03:51:11

    I changed above query using the Forum gurus, below query is changed:


    Select concept_Un, raw_concept_a, relation_name, concept_b, raw_concept_b

    of discovered_relations

    where regexp_instr (concept_Un, ' (consumer.*confidence) |) ((confidence.*Consumer))', 1, 1, 1, 'i') > 0;

    I created indexes for query modified as well:
    creating index SIDEV. IDX_reg_instr on SIDEV. DISCOVERED_RELATIONS (REGEXP_INSTR ("CONCEPT_A",'(consumer.*confidence) |)) (confidence.*Consumer))', 1, 1, 1, 'i'));

    After that the cost and time to get request reduces to:
    After optimization: 40001 and 08:01

    Now the question is whenever my request will vary as a condition, this means that search string can be vary to any value.

    So I need a basic index as function above is the index which can work for any string in the like operator, now my created index only works very well for the fixed string...

    Thank you

    Thank you very much its working well, now, to reduce the cost and duration of execution, I used below queries as you suggest:

    create index idx_fulltext on discovered_relations (concept_a) indextype is ctxsys.context;

    Select * from discovered_relations

    where contains (concept_a, 'Confidence') > 0 and contains (concept_a, 'Consumer') > 0;

    Hello

    No, you didn't.

    The query I used was

    Select str

    of test_idx

    where

    contains (str, '% of the CONSUMPTION and CONFIDENCE %') > 0

    If you read carefully, you'll notice that I used already found lowercase uppercase searchwords.

    This works because the oracle text case insensitiv default you can read documentation:

    "By default, all text tokens are converted to uppercase and then indexed. This

    results in case-insensitive queries. For example, separate queries for each of

    the three words, CAT cat,

    "and Cat all return the same documents.

  • How to create indexes on the ordered collection of XMLTYPE table?

    I use Oracle 11.2.0.2.

    Basically, my XML documents have a 3-level hierarchy:

    event

    + - action [1: n]

    + - param [1: n]

    I try to create indexes on the tables of the orderly collection, but cannot get the right syntax...

    I created a table with an XMLType object-relational column:

    CREATE TABLE T_C_RMP_MNTRNG_XML_FULL_IL4 (
  MESSAGE_ID NUMBER(22,0) NOT NULL ENABLE,
  XML_EVAL_ID NUMBER(22,0),
  VIN7 VARCHAR2(7 BYTE),

  RECEIVED DATE,

    I execute the SELECT statement:

    SELECT EVENT_ID, ACTION_SUB_ID, MESSAGE_ID, ACTION_TYPE, UNIXTS_TO_DATE(ACTION_TIMESTAMP) ACTION_TIMESTAMP
FROM T_C_RMP_MNTRNG_XML_FULL_IL4, 
XMLTABLE( 
  'for $i1 in /monitoring ,

  $i1/eventId,              
  $i2            
  }' 
  PASSING XML_CONTENT COLUMNS 
  EVENT_ID VARCHAR(40) PATH 'eventId',

    How can I create an index on these tables of the ordered collection to improve performance?

    I found the example at http://docs.Oracle.com/CD/E11882_01/AppDev.112/e23094/xdb_rewrite.htm#ADXDB5859 but am not able to apply to this particular case...

    Thank you in advance...

    If the schema is not annotated and XS: Integer and XS: String are mapped to types of data NUMBER and VARCHAR2 (4000), so you must use in your query to avoid typecasting unnecessary operations.

    You must also use XMLTABLEs chained when accessing a parent/child instead of a FLWOR expression relationship, otherwise the CBO cannot rewrite the XQuery query correctly (maybe it's fixed in the latest version).

    If you make these changes, the plan should show the cleaner predicates:

    SQL > SELECT EVENT_ID, MESSAGE_ID, ACTION_TYPE, ACTION_SUB_ID, ACTION_TIMESTAMP

    2 FROM test_table

    3 XMLTABLE ('/ monitoring ')

    4 COLUMNS XML_CONTENT OF PASSAGE

    5 WAY of VARCHAR2 (4000) EVENT_ID "ID."

    6 actions for XMLTYPE PATH 'action '.

    (7) T1,

    8 XMLTABLE ('/ action')

    Shares of PASSAGE 9 COLUMNS

    NUMBER of ACTION_SUB_ID 10 PATH "actionSubId."

    11 PATH of VARCHAR2 (4000) ACTION_TYPE "type."

    12 WAY of NUMBER ACTION_TIMESTAMP 'time '.

    (13) T2

  • How can you change a form you've already created?

    I do not speak for the form fields. I mean if you have a typo in, for example, in the docuyment that you have created in InDesign and now you must go back and correct it. How can you do this and maintain any fields that you have already created?

    If you are not able to do this, it would be a huge flaw in the workflow.

    The easy way is to make the change in InDesign, re-export the PDF file and then use Pages to replace in the Document Menu to replace the content of the original with the corrected file file. He maintains the form fields to their original position.

  • How to create indexes on columns all - the flames begin

    Yes read you it correctly.

    Is it possible to create a procedure that will create an index on each column in a table without specifying the column names?

    index_all_cols exec ('xxx', 'parallel');

    You ask why? There is no reason that I can give you that will quench the flames coming my way. But, finally, it's because (1) I am tired of using excel to generate create statements of the index and (2) I want the speed at the expense of everything else, (3) I do not use a mouse... I know, I would hate first.

  • How can I view the guides of purge in a document already created

    I went to the file, Document format and created a saignement.125 for a document that I have already created, but I do not see the guides to bleed.  Under view Grides and Guides 'Hide Guides' watch.  I have this turned on or off and still do not see the guides to bleed.  If I start a new document with the guides to bleed, I see the guides to bleed.

    Who's going to switch the Preview layout on the page (assuming that you do not have a text insertion point active), but it will not disable the overprint preview. The shortcut is Alt + Ctrl + Shift + Y on Windows, or Cmd + Opt + shift + Y on Mac, or just use the view menu for that.

    There are also buttons at the bottom of the tool box to control page/preview mode, and you can use the view menu to do this, too.

  • How to create indexes on the nested table.

    Hi all
    I held the syntax to create indexes on the nested table.

    I found below synta but when I try it with my table it gives me error

    CREATE UNIQUE INDEX indx_name
    ON nestedtablestore (NESTED_TABLE_ID, id);

    What is here NESTED_TABLE_ID & ID

    They are virtual your nested table

    Here is an example.

    create or replace type obj as object (no integer, address varchar2(100))
/
create or replace type tbl as table of obj
/
create table test_tbl (id integer, name varchar2(100), address tbl) nested table address store as address_nt
/
create unique index address_no_idx on address_nt (no, address)
/

  • How to disable the index to the rows of the table updated

    Hello world

    I have a problem on a table with Oracle11g.

    I would update a table a lines opposite two in a table. This table has an index, and during the inversion, the index is duplicated.

    So, I turn off the index and then rebuild all indexes like this: How to disable the index in oracle

    However, I can't update a table when my index finger is rolled unusable.

    I create my table:

    CREATE  TABLE MY_TABLE(
  ID                         NUMBER(5) NOT NULL,
  TYPE                        NUMBER(1) NOT NULL,
  PRIO                       NUMBER(4) NOT NULL,
  CONSTRAINT PK_MY_TABLE
    PRIMARY KEY (ID, TYPE )
);

CREATE INDEX  PRIO_UK
    ON MY_TABLE(TYPE, PRIO);

    Then I selected all the elements and the results is:

    ID Type Prio
    1110
    2111

    Then, I tried to update this list with this script:

    UPDATE MY_TABLE set PRIO = 11 WHERE ID = 1 AND TYPE = 1;
UPDATE MY_TABLE set PRIO = 10 WHERE ID = 2 AND TYPE = 1;

    I have an error on the first line, because the subscript for type 1 and 11 priority already exist.

    You have another solution to solve my problem?

    I thank you very much.

    Do not disable your index. Just perform your update with a single blow. Like this

    SQL> select *
  2    from my_table;

        ID       TYPE       PRIO
---------- ---------- ----------
         1          1         10
         2          1         11

SQL> update my_table
  2     set prio = case when id = 1 and type = 1 then 11
  3                     when id = 2 and type = 1 then 10
  4                end
  5   where (id = 1 and type = 1)
  6      or (id = 2 and type = 1);

2 rows updated.

SQL> select *
  2    from my_table;

        ID       TYPE       PRIO
---------- ---------- ----------
         1          1         11
         2          1         10

  • Creating INDEX on a BLOB column in a separate tablespace

    Hello


    Our database contains 2 storage spaces :

    -Tablespace DATA : is reserved to hold the data.

    -Tablespace INDX: is reserved to hold the index.


    For some reason, that we must create the indexes on columns of type blob and the pending order are:

    SQL > CREATE INDEX my_index ON DOC_CONTENTS (doc_content) INDEXTYPE IS CTXSYS. CONTEXT;  / / doc_content a blob type.

    SQL> index created

    Now, all indexes are created in the tablespace for DATA that is not good, they should be created in the tablespace INDX (now is empty)

    For this reason, and after a search, I specified the tablespace INDX , which will contain the index, and the used command is:

    SQL > CREATE INDEX my_index ON DOC_CONTENTS (doc_content) INDEXTYPE IS CTXSYS. CONTEXT TABLESPACE INDX;

    *

    ERROR on line 1:

    ORA-29850: invalid option for creating domain index

    NB: also, when I try to use the same command with varchar column, it works.

    SQL > CREATE INDEX my_index ON DOC_CONTENTS (doc_name) TABLESPACE INDX;  / / doc_content a type VARCHAR2.

    SQL> index created


    Do you have an idea on how to create indexes on a blob column in a different tablespace?

    This question has nothing to do with the Oracle objects, but is related to Oracle Text, then perhaps that some moderator moves text objects.

    To specify a storage space for a ctxsys.context Oracle Text index domain index tables, you must create a storage preference, specify storage spaces in attributes of this preference, then use this preference in settings of creating index.  Please see the example below which shows first create domain index tables in the default users tablespace, then the creation of the field tables to be indexed in the example tablespace.
