create indexes on the upper part of the column - reminders function is not deterministic

Hi all

I'm having a problem on a database. When you create an index on an existing table on the upper part of a column, Oracle triggers an ORA-30553. I've done this 40 index other databases, with the same and different versions, without problem. When you create the index on a copy of the table, it is created with success...

Here is the code:

SQL > select * from v version $;

BANNER

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

Oracle Database 11 g Release 11.2.0.3.0 - 64 bit Production

PL/SQL Release 11.2.0.3.0 - Production

AMT for 64-bit Windows: Version 11.2.0.3.0 - Production

ERROR on line 1:

Table created.

SQL > CREATE INDEX IDX_SRE_E_MAIL_UPPER on fsynrelatie2 (upper (sre_e_mail)) tablespace idx;

The index is created.

SQL > drop table fsynrelatie2;

Deleted table.

SQL > show parameter query_rewrite_enabled

VALUE OF TYPE NAME

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

query_rewrite_enabled string TRUE

Hi all

Thank you for the answers. I found the problem:

On the table, there are 54 index:

Select index_type, uniqueness, count (*) from user_indexes where table_name = 'FSYNRELATIE '.

Index_type group, uniqueness

INDEX_TYPE	SINGLE CHARACTER	*COUNT ()**
FIELD	ARE NOT UNIQUE	1
BASED ON A NORMAL FUNCTION	ARE NOT UNIQUE	4
NORMAL	UNIQUE	3
NORMAL	ARE NOT UNIQUE	46

3 unique indexes are the primary key and 2 another witch number field contains unique identifiers for rows in other systems. The domain index is an index of Oracle text on a couple of fields. There are 3 indices of function based on a high on a field and 1 on an individual function. This last clue has caused the problem. Apparently, on the creation, this function is deterministic, but when rolling a new version of the software. It became a non-deterministic function. When I delete the index, my original index on upper (sre_e_mail) has been created successfully! Now, I did the deterministic function again and could recreate the function without problem.

Thanks for your comments!

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.

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.

Table dropped.

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

Creating indexes for the table

can someone help me how to create indexes in the table. I m creating own table... I need to select a particular field in the table. So I need to calculate the index position. I use my code like this,

This will returnthe number of columns in the table.

Class array

{

private int Table_Index()
{
for (int x = 0; x)<>
{
table_index = x;
}
Return table_index;
}

}

MainClass can I get this length of Index

Table T1;

int t1 is T1. Table_Index();

This property returns my length (4) of table column

Using this index (t1) I HAV to see what position I'm at table now...

someone help me...

You can use a listfield, he supports methods to get the selected row and its contents.

Why I can't create indexes on the table of RDF data

When I tried to create indexes on the table of RDF data, it always say the table or view does not exist. I created the RDF model using java codes:
Oracle Oracle = new Oracle ("jdbc:oracle:thin:@localhost:1521:orcl", "system", "123");
Chart GraphOracleSem = new GraphOracleSem (oracle, "test2");

And used the following commands in sqlplus to create indexes:
SQL >
SELECT THE SEPARATE OWNER, OBJECT_NAME
FROM DBA_OBJECTS
WHERE TYPE_OBJET = 'TABLE '.
4. AND OBJECT_NAME like ' % TEST2;
OWNER
--------------------------------------------------------------------------------

Hi Shifu,

It is not recommended to use the SYS or SYSTEM to store/manage schema graph RDF data.

Can you please try the following in a SQL * more terminal?

SQL > conn system/eu1

Connected.

SQL >

SQL >

SQL > create user graphuser identified by graphuser;

Created by the user.

SQL > grant connect, resources, unlimited tablespace to graphuser;

Grant succeeded.

SQL > conn graphuser/graphuser

Connected.

SQL > create table graph_tpl (triple sdo_rdf_triple_s) compress;

Table created.

SQL > sem_apis.create_sem_model exec ('graphic', 'graph_tpl', 'three');

PL/SQL procedure successfully completed.

SQL > insert into graph_tpl values (sdo_rdf_triple_s ('graph', '', '', ''));

1 line of creation.

SQL > select count (1) in the mdsys.rdfm_graph;

1

You see the same result?

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

ALTER INDEX dev. "" SYS_IL0000718396C00002$ $"REBUILD TABLESPACE DATA_TEMP

ERROR on line 1:
ORA-02327: cannot create indexes on the LOB data type expression

Thank you

correct syntax is
ALTER TABLE.
MOVE the LOB ()
STORE AS (tablespace );

Where is a name of the / columns LOB, not the name of the segment. Moving type LOB data will move its indexes as well.

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)
/
```

That could leave gaps in the index, but the built-in function NEXT allows you to iterate over any series of clues.

Hello
can you please explain the below topic?
That could leave gaps in the index, but the built-in function NEXT allows you to iterate over any series of clues. -> this line
1. Arrays have a fixed upper bound, but the nested tables are unlimited (see Figure 5-1). Thus, the size of a nested table can increase dynamically.
Table in figure 5-1 against the nested Table

Description of the illustration pls81016_array_versus_nested_table.gif
- Tables should be dense (have consecutive indices). So, you can delete individual items from a table. Initially, the nested tables are dense, but they can become sparse (have non-consecutive indexes). So, you can remove items from a table nested by using the integrated procedure DELETE . That could leave gaps in the index, but the built-in function NEXT allows you to iterate over any series of indexes.
Hello

Look at the second half of the Figure 5-1, the 'Nested Table after destruction". X (9), x.5 and x (2) elements have been removed, so the index values are 1, 3, 4, 6, 7, 8 and 10. There is a gap between 1 and 3, another gap between 4 and 6 and another gap between 8 and 10.

You could not use a simple FOR loop:

FOR j IN 1... 10

LOOP

...

END LOOP;

to iterate over a collection of rare as this, but you can use a loop where you get with the FOLLOWING indices:

j: = x.FIRST;

Then j IS NOT NULL

LOOP

...

j: = (j) x.NEXT;

END LOOP;

index on the column of low cardinality
Hello
Standard edition Oracle 10.2

I have a 'status' column in my table. table contains about 100000 records.
The possible values of status will be 1 or 2 (digital). This column will be 5 to 10 percent of the population, and the rest is null.

Because it is seems that bitmap index is candidate for low cardinality column, but this picture has high of DML operations. SO by web research I learned about this bitmap causes problems of blocking on high DML operations.

So I think that B-tree is only option left. Can you suggest a good index to improve performance on such a column?
You don't need an index based on a function, do you think?

You have a STATUS column where a small percentage of values is not null.

To effectively access these lines whose STATUS is non-zero, simply create an index on the column State.

This should be plenty effective.

The effectiveness of this index (or the fbi if she was forced) is based on the fact that an index b-tree contains entry when the value is null (or all of the values in the case of a composite).

There are those that 100000 is small and 5-10% is not particularly selective and you tell the width of the table, etc., so, even with the index here, it might not if used - i.e. depending on the circumstances it might be more efficient to do a FTS.

It depends on what you want to do.

Get the index of the column of table removed

Is there a way to get the index of the column in a 2D table that has been deleted? In my application, the user has the possibility to use the right click option 'remove a column' on a 2D picture, but I would like to use this information to remove the same column in a different table programmatically. Is this possible?

There is a file published in the documents of the community that refers to a location in a sheet of the user has clicked. Use it like the image below.

How to create indexes for the great table of telecom
Hello

I'm working on DB 10 G on a 5 REHL for telecommunications company with more than 1 million saved per day, we need speed up the result of the query.
We know, there are several types of INDEX and I need professional advice to create a suitable,

many of our requests depend on the MSID (the MAC address of the Modem) column,
```
   
Name           Null Type         
-------------- ---- ------------ 
STREAMNUMBER        NUMBER(9)    
MSID                VARCHAR2(20) 
USERNAME            VARCHAR2(20) 
DOMAIN              VARCHAR2(20) 
USERIP              VARCHAR2(16) 
CORRELATION_ID      VARCHAR2(64) 
ACCOUNTREASON       NUMBER(3)    
STARTTIME           VARCHAR2(14) 
PRIORTIME           VARCHAR2(14) 
CURTIME             VARCHAR2(14) 
SESSIONTIME         NUMBER(9)    
SESSIONVOLUME       NUMBER(9)    
.
.
.
```
Please help,
Hello

first of all, think of all these SQL for the subquery on MAX (fairy) with analytical functions, the examples given on AskTom of rewriting: http://asktom.oracle.com/pls/asktom/f?p=100:11:0:P11_QUESTION_ID:9843506698920

So I'll start with a normal index the MSID (but I think you already have), but provide a compression on the column, I think the same value MSID exist several times in the table. If the performance is not satisfactory or that the plan is not the best, then an option to include more columns can help you.

I think that the first part of the answer will bring more gain.

Cannot create indexes on the flow table

I'm new to ODI.
The problem is that during the execution of an interface, I get the error of the "IKM Oracle Dimension to slow variation"
The command in step "Create unique index on the flow table:

Hello

I'm really really sorry! I just realized that you are working on the SCD. Basically, you are looking for all the column mapped as SCD_NK (key to slowly change natural Dimensions) insofar as shown here

Creating indexes in the XMLType column
Hello

I have the following for XML document stored as an XMLType column.

< ocaStatus xmlns = "http://xmlbeans.apache.org/ocastatus" > < status > < > 934 statusCode < / statusCode > < statusDate > Wed Apr 07 16:05:53 GMT + 05:30 2010 < / statusDate > < userId > u0121845 < / userId > < comment > sent to FLC < / comment > < / status > < status > < statusCode > 934 < / statusCode > < statusDate > Wed Apr 07 15:58:25 GMT + 05:30 2010 < / statusDate > < userId > u0121845 < / username > < Comment > sent to FLC < / comment > < / status > < status > < statusCode > 934 < / statusCode > < statusDate > Wed Apr 07 15:54:02 GMT + 05:30 2010 < / statusDate > < userId u0121845 > < / userId > < comment > sent to FLC < / comment > < / status > < status > < statusCode > 750 < / statusCode > < statusDate > 2010 - 03 - 31 12:39:41.580 GMT + 05:30 < / statusDate > < u0121845 userId > < / userId > < comment > metadata of the Document is correct. < / comment > < / status > < status > < statusCode > 934 < / statusCode > < statusDate > 2010 - 03 - 31 12:39:41.580 GMT + 05:30 < / statusDate > < userId > u0121845 < / userId > < comment > sent to FLC < / comment > < / status > < status > < statusCode > 932 < / statusCode > < statusDate > 2010 - 03 - 31 12:39:41.580 GMT + 05:30 < / statusDate > < userId > u0121845 < / username > < comment > loaded Novus < /. comment > < / status > < status > < > 700 statusCode < / statusCode > < statusDate > 2010 - 03 - 31 12:39:41.580 GMT + 05:30 < / statusDate > < userId u0121845 > < / userId > < comment > Document is deleted from the OCA. < / comment > < / status > < / ocaStatus >

I created as a result of the clues in the XML
CREATING INDEX 'OCA_DEV '. "' OCA_STATUS_CODE_INDEX ' ON 'OCA_DEV '. "DOCUMENT_STATUS_XML"(EXTRACTVALUE('/ocaStatus/status/statusCode'));
CREATING INDEX 'OCA_DEV '. "' OCA_STATUS_DATE_INDEX ' ON 'OCA_DEV '. "DOCUMENT_STATUS_XML"(EXTRACTVALUE('/ocaStatus/status/statusDate'));

However, the problem is that I will be having several status within each XML that violates the indexing.
Is there a way I can still create indexes for multiple State values in each XML file?

Thanks in advance.
Hello

Take a look at the manual xdb (which version do you use?), for the 10.2 version, see: http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14259/xdb04cre.htm#sthref596
It describes how you can index an XMLTYPE. Because you describe how you use, take a look at your needs.

In 11G, you have the XMLINDEX to xmltypes indexing, you will find information here: http://download.oracle.com/docs/cd/E11882_01/appdev.112/e10492/xdb_indexing.htm#CHDFCGGI

a question about creating index on the view
Hi all

I had a problem on the creation of an index on the view

create index sys_ixf_viewpnuc_03 on view_pnuc (ugcode | privatenum);

It's the sql I've run pl/sql

the result of the server is:
SQL error: ORA-01702
01702 00000 - "a view is not appropriate here.

Thanks for giving me a helping hand

TKS
Hello

You can not use the index on the view...

better, you can create a view with the best of the select statement with the specified indexed column...

Since then, the view is nothing other than a select statement. If any changes in the index, alter in the table and create a consequence of the view...

canno't ' t you create an index on a view except the materialized view

Kind regards
Deepak

create indexes on the upper part of the column - reminders function is not deterministic
