Created index with DESC with USER_IND_COLUMNS. COLUMN = ' SYS_NC00023$ '.

On Oracle 11.2, I observed below

create index ind_jperson_1 on d_jperson(convict_ref);
create index ind_jperson_2 on d_jperson(driver_ref DESC);

select index_name,table_name,column_name,column_position,descend
  from USER_IND_COLUMNS where  table_name='D_JPERSON'

INDEX_NAME     TABLE_NAME     COLUMN_NAME     COLUMN_POSITION     DESCEND
IND_JPERSON_2     D_JPERSON     SYS_NC00023$     1     DESC
IND_JPERSON_1     D_JPERSON     CONVICT_REF     1     ASC

How to find the true picture of this index column?

Hello

DBA_IND_EXPRESSIONS can help you find the real column name.

And it is an expected behavior in Oracle. Have you noticed anything else pre 11.

NOLOGGING will cease to produce data AGAIN... for which you want to execute the instructions.
Nothing wrong... it is created by ORACLE ;-)

read this and cross with your process. You can do it with nologging option.

Performance problem of creating index with LOB/CLOB content

Hello

I have a problem with indexing performance with a table containing columns of text
also a clob and a lob column.

Indexing with 20,000 lines takes about 1 hour on 11.2.0.4 with the last batch of patches 12 on
win x 64.

on a 11.2.0.1, the process is done in a few minutes.

So what can I do to find out where is the problem?

I use filter auto and basic lexer.
Operating system is W 2008 R2 SP and latest patches. OS lang is English.
DB is installed with AL32UTF8 and German and English language packs.

also watched and ctx_user_index_errors and pending and there is no error or waiting in lines.
After the index is created, everything works fine. during the creation of index no other user is connected to the database.

so why 11.2.0.1 is so much faster than 11.2.0.4?
some advice for me?

Thank you!

Hello

so I solved all my problems.

So I made two changes:

1. I declared the variable theNotiz2 for recording the output for the raw text of the column NOTIZ (is a clob), add the output to the Out-Clob parameter

2. I used the same variable for the--> this blob field caused an error with line with lob is not locked... so I said a second variable for this and that solved the problem.

normally, I think it should work with 1 variable... but is an acceptable workaround.

Performance now is OK because the procedure, I can set on which the documents I want to do a search or not.

Second thing, but has nothing to do with Oracle: my frontend application makes a ZIP for each insert in a column lob and if the ctxhx does not index the content, the MDC, and before calling the conversion of plain text, so I have to make a decompression of the blob...

so for now, all problems solved. Thank you for your support.

Cannot create Index with an If statement
Hello:

I would run the code to create an index on a given table, but only if the index does not exist. Here's what I have so far...

DECLARE
c_Count NUMBER;
BEGIN
SELECT COUNT (*) FROM c_Count
OF DBA_INDEXES
WHERE TABLE_NAME = 'SOME_TABLE_NAME '.
AND INDEX_NAME = "SOME_INDEX_NAME."
AND OWNER = 'SOME_OWNER. '
AND TABLE_OWNER = "SOME_OWNER";
IF c_Count = 0 THEN

CREATE INDEXES SOME_OWNER. SOME_INDEX ON SOME_OWNER. UNE_TABLE (SOME_KEY);
END IF;
END;

The SELECT INTO statement works well alone.
Boredom comes with the IF statement. I get the following error message:

PLS-00103: encountered the symbol "CREATE" when waiting for one of the following values: begin case declare exit for goto if loop...

This is the typical error saying that the syntax is incorrect, and that the parser was expecting something else after the IF-THEN statement. Any ideas on what may be a problem? Thanks in advance.

Hello

You must use EXECUTE IMMEDIATE to the DDL in PL/SQL.
```

Field in the list with 2 columns

I am creating listfield with two columns as follows [2 |] Cokes].

There is an example on how to do this?

There is an article on the basis of knowledge to developers to add checkbox to a field, but I don't see anything on the creation of several columns.

Maybe I can get away with adding a field of text instead of a checkbox or have two fields next to the list and sync.

any suggestions?

ListField on nature has a great column.

You can override drawListRow() to ListFieldCallback to divide each row number of columns.

In this case, you will need to control the width of each column using the class font getAdvance() method that returns the width of the displayed string. And if you combine graphics and text in columns, you will need to also use getWidth() instance method of the Bitmap class to calculate the width of each column.

Declare a type of table with multiple columns
I have a table with a column of type, and I want to create one with two columns.

My type is:
create or replace type "NUMBER_TABLE" in the table of the number;

And I use it in function:

FUNCTION GetValues()
return NUMBER_TABLE
as
results NUMBER_TABLE: = NUMBER_TABLE();
Start
Select OrderId bulk collect in: results from (select * from tbl_orders);
-Other code...
end;

I want select it be like this:
Select OrderId, OrderAddress bulk collect into: results from (select * from tbl_orders);

How to do this?
Is that what you are looking for:

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),
  FLEET_ID VARCHAR2(50 BYTE),
  CSC_SW_VERSION VARCHAR2(100 BYTE),
  RECEIVED DATE,
  XML_CONTENT SYS.XMLTYPE ,
  DWH_LM_TS_UTC DATE NOT NULL ENABLE,
  CONSTRAINT PK_C_RMP_MNTRNG_XML_FULL_IL4 PRIMARY KEY (MESSAGE_ID)
) NOLOGGING TABLESPACE CATALOG
VARRAY "XML_CONTENT"."XMLDATA"."action" STORE AS TABLE "T_OR_MON_ACTION" (
  NOLOGGING TABLESPACE "CATALOG"
  VARRAY "param" STORE AS TABLE "T_OR_MON_ACTION_PARAM" (
  NOLOGGING TABLESPACE "CATALOG"
  ) RETURN AS LOCATOR
) RETURN AS LOCATOR
XMLTYPE XML_CONTENT STORE AS OBJECT RELATIONAL XMLSCHEMA "http://mydomain.com/cs.xsd" ELEMENT "monitoring";

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 , 
  $i2 in $i1/action            
  return element r {              
  $i1/eventId,              
  $i2            
  }' 
  PASSING XML_CONTENT COLUMNS 
  EVENT_ID VARCHAR(40) PATH 'eventId', 
  ACTION_SUB_ID INTEGER PATH 'action/actionSubId', 
  ACTION_TYPE VARCHAR2(100) PATH 'action/type', 
  ACTION_TIMESTAMP NUMBER(13,0) PATH 'action/time' 
) T2 
WHERE ( 
  EVENT_ID IS NOT NULL AND ACTION_SUB_ID IS NOT NULL 
)

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

14 WHERE EVENT_ID IS NOT NULL

15 AND ACTION_SUB_ID IS NOT NULL

16;

-dynamic sample used for this survey (level = 2)

Now, if it is still necessary, everything boils down to choosing a technique for index NULL values:

-composite index with a column not zero or constant

-FBI

-bitmap image

Choose the one that best fits your data, the selectivity and activity on the tables.

create xmlindex structured with multiple columns reflecting different XPath expressions

I run a XMLEXISTS query to return documents that contain a specific search template. The search model is based on two distinct XPATHS. I tried to create an XML Index structured to support the request. While I can make it work when I specify that a XPATH, I can't make it work when I specify both.
Oracle version: 11.2.0.3
extendeddata / / DESC

Can someone help me build an index for the query above?
Thank you.

This should work better, with the caveat explained above:
```
SELECT t.*
FROM extendeddata t
WHERE XMLEXISTS('declare default element namespace "urn:iso:std:iso:20022:tech:xsd:camt.054.001.02";(::)
               /Document/BkToCstmrDbtCdtNtfctn/Ntfctn[Acct/Id/IBAN=$iban]'
        Passing Xmlcontent,
                'XXXXXXXXXXXXXXXXXXXXXX' AS "iban"
           )
and XMLEXISTS('declare default element namespace "urn:iso:std:iso:20022:tech:xsd:camt.054.001.02";(::)
               /Document/BkToCstmrDbtCdtNtfctn/Ntfctn[Ntry/CdtDbtInd=$ctddbtind]'
        Passing Xmlcontent,
                'DBIT' as "ctddbtind")
AND rowinsertdate >= TO_DATE(' 2014-01-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS')
AND rowinsertdate < TO_DATE(' 2014-07-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS')
;
```
(see how the predicates in each XQuery expression corresponds to the structure of the index)

BTW, this kind of "DIY" XMLEXISTS works just as well.

It emulates what we would have hoped for a single XMLExists in the first place:
```
SQL> SELECT t.*
  2  FROM extendeddata t
  3  WHERE rowinsertdate >= TO_DATE(' 2015-06-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS')
  4  AND rowinsertdate < TO_DATE(' 2015-07-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS')
  5  AND EXISTS (
  6    SELECT null
  7    FROM XMLTable(
  8           XMLNamespaces(default 'urn:iso:std:iso:20022:tech:xsd:camt.054.001.02')
  9         , '/Document/BkToCstmrDbtCdtNtfctn/Ntfctn'
 10           passing t.xmlcontent
 11           COLUMNS IBAN      VARCHAR2(34) PATH 'Acct/Id/IBAN'
 12                 , CTDDBTIND VARCHAR2(4)  PATH 'Ntry/CdtDbtInd'
 13         ) x
 14    WHERE x.iban = 'XXXXXXXXXXXXXXXXXXXXXX'
 15    AND x.ctddbtind = 'DBIT'
 16  ) ;

someone had such a problem?

concerning

I think the UPDATE GLOBAL INDEXES is the origin of the problem.

Try this,

ALTER TABLE IS_PODACI209 EXCHANGE PARTITION P_201012 WITH TABLE IS_PODACI209_STAGE EXCLUDING INDEXES WITHOUT VALIDATION

Rebuild the indexes manually.

I created a table with a column of data type such as varchar2

with index I executed the query

There is no change between these to explain plans, no performance difference?

is that B-TREE index works well with number data types?

Thank you
REDA
There could be several reasons. After you create the index statistics gather e.g. also maybe your query returns a huge part of table index will be useless. I mean if you ask him % of 80 percent of one table, optimizer will probably not use index. Another reason, perhaps your table is too small, so oracle read both so the whole table, it is not necessary use index. etc...

It is not on the varchar2 data type, if one of these conditions is tru that whatever your index of data type will not be used.

How to create a table with editable column values.
Hello world
I think it's very simple, but I am unable to find how to do this. This is my requirement. I need to create a table with n columns and 1 line initially. the user must be able to enter data into this table and click of a button must insert the data into the database table. Also, there should be a button at the bottom of the table to add 1 line to the table.

I know how to do the insertion of data, but can someone please let me know how to create a table which allows the user to enter data and how to create a line button Add 1?

Thanks in advance!
Raghu,

Go through the tutorial of Toolbox Page & Advanced section of the Guide of the OFA table.

Step 1 - you need to create EO & VO from this EO. This EO will be table of database where you want to insert the data.

Step 2 - create an advanced table region. (See this section in table advanced for more details)

Step 3 - attach this VO in the BC4J region advanced Table component.

Kind regards
GYAN

Creating table in the model with 80 columns
Hello

I am trying to create a model to display 80 columns, but in Word format, I get the message "you cannot create a table with more than 63 columns.
Can how I put the 80 columns in the Template.rtf?

Env: Suite Oracle E business 12
Output required: Excel

Thanks in advance.
It's the MSword limitation and no BEEP, but indirectly there is a limitation of the BEEP ;)

MSWord supports only maximum of 63 columns.
As MS Word supports only the width of page maximum of 22 inches wide and 22 inches high.

Option 1:

Create a table with two columns
Insert a table with 63 columns in the first cell,
Insert a table with 63 columns in the second cell,
How we can get rid of limitations columns.

Option 2:

If you want to use more than 63, then you use templates other than RTF. I recommend XSL.
