Creating indexes in the XMLType column
HelloI 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

I want to create indexes for child nodes. I read THAT XML structure cannot have collection as index it should be singleton.
So can someone tell me no work around to create indexes for these nodes, or whatever it is that I missed as follows.

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 )The plan of the explain command looks like this (sorry, don't know how to get it formatted any 'eye-team'):

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

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.

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.

ADF and the use of the XMLType columns
After discovering the Jdeveloper 11 g was able to generate business components/data controls for complex web services (see this tutorial excellet http://www.oracle.com/technology/tech/fmw4apps/agile/pdf/adf11g-agile.pdf), I assumed that jdev 11 g should now have the same capacity on XMLtype columns with a registered scheme, and was therefore a good match for our enforcement objectives be able to edit
parts of an XML document to aid in the face of components and Assembly/store the document in a way centic document in a relational/XML database XMLType column hybrid.
I tested this point, has created a table with an XMLType column binary, saved the schema in database (11g) and jdev(11g) and generated my components.
I was very disappointed at the discovery of the structure of data controls stops at the level of the attribute in the table (ie the XMLType column), so none of the structure of the XML document is revealed or can be used in a meaningful way through data control.
Am I missing something here? should not control data generated reveal the XML structure and allow the use of components of forms/table faces on some parts of the structure of the document? I'm not a java programmer, so was really hoping to do this with data not generated controls beans not.
If it is just to treat it as a CLOB, what's the point of registered xsd schemas?Yes, it is through java. Sorry

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 >

WHERE TYPE_OBJET = 'TABLE '.
4. AND OBJECT_NAME like ' % TEST2;

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?

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 & IDThey 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) /Published by: Karthick_Arp on November 23, 2010 01:41

The XML is very long. For insertion in the table, I use xmlparse() function to get XMLType.
While doing this I'm ORA-01704: string literal too long error. It is said can accommodate maximum 4,000 characters.
I guess that XMLType is stored as a default CLOB. So it should allow more than 4000 characters.
How can I store data xml with more than 4000 characters.
Thank you.XMLParse is a SQL function, you cannot use a string literal is longer than 4000 characters.
Instead, you can declare a PL/SQL VARCHAR2 variable, which can contain up to 32 k characters and use the XMLType constructor:
DECLARE xmlstr VARCHAR2(32767) := ''; xmldoc xmltype; BEGIN xmldoc := xmltype(xmlstr); INSERT INTO your_table(xml_data) VALUES(xmldoc); END; For strings longer than 32 k, you may need to load it from a file.

Help - query on the XMLType column?
Hello
Please could someone help me to write a query to extract data from XMLType column in the script below:
Here is my example of WHAT XML stored in the XMLType column:
I want to retrieve ActivityDate and ActivityTime where ActivityID/ID = 'something'...<?xml version="1.0" encoding="UTF-8"?> <cf:IncidentReportGroup xmlns:cf="http://xml.crossflo.com/jxdm/3.0.3" xmlns:j="http://www.it.ojp.gov/jxdm/3.0.3" xmlns:ext="http://xml.crossflo.com/jxdm/3.0.3/extension" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:i="http://www.it.ojp.gov/jxdm/appinfo/1"> <cf:IncidentReport> <ext:Incident> <j:ActivityID> <j:ID>99999999999999</j:ID> </j:ActivityID> <j:ActivityDate>2007-01-13</j:ActivityDate> <j:ActivityTime>01:25:00Z</j:ActivityTime> </ext:Incident> </cf:IncidentReport> </cf:IncidentReportGroup>
Here is the example query I wrote but no luck:
SELECT extractValue(xml_doc, '/cf:IncidentReport/ext:Incident/j:ActivityDate','/cf:IncidentReport/ext:Incident/j:ActivityTime') FROM TABLEA where existsNode(xml_doc,'/cf:IncidentReport/ext:Incident/j:ActivityID[j:ID="99999999999999"]')SQL> var ID varchar2(20) SQL> exec :ID := '99999999999999' PL/SQL procedure successfully completed.

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 $;

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!

Hello
I have a requirement to insert a new XML tag in the existing XMLTYPE column.
Oracle version: Oracle Database 11 g Enterprise Edition Release 11.1.0.7.0 - 64 bit Production
create table rds_xml_config (module_name varchar2 (32), module_type varchar2 (100), config_xml xmltype);
insert into rds_xml_config values ('TRANSMIT_SEQ', 'INTERFACE',' < transmit_seq > <!-file sequence number will be updated after each race-> < file = "RTP" Type_de_fichier > < file_seq_num > 2457 < / file_seq_num > < / file > < file Type_de_fichier = 'RTS' > < file_seq_num > 2453 < / file_seq_num > < / file > < Type_de_fichier = "RTL" file > < file_seq_num >) 2522 < / file_seq_num > < / file > < / transmit_seq > ');
I have to add < file = "RTX" Type_de_fichier > < file_seq_num > 0 < / file_seq_num > < / file >.
As a temporary work around, I used below the update statement.
Update rds_xml_config
Set config_xml =' < transmit_seq > <!-file sequence number will be updated after each race-> < file = "RTP" Type_de_fichier > < file_seq_num > 2457 < / file_seq_num > < / file > < file Type_de_fichier = 'RTS' > < file_seq_num > 2453 < / file_seq_num > < / file > < Type_de_fichier = "RTL" file > < file_seq_num > 2522 < / file_seq_num > < / file > < file = "RTX" file_type > < file_seq_num > 0 < / file_seq_num > < / file > < / transmit_seq > '
WHERE module_type = "INTERFACE".
AND module_name = "TRANSMIT_SEQ";
SEQ numbers will be modified for each race of the file, so I cannot use the work temporary around during migration to production, have we a way to add new XMLtag.
Thank you
