Insert in varchar2 select xmltype column: extremely slow
I use oracle10gR2 10.2.0.4 and solaris10 64bits
I need to select the data to an xml value in a table of column xmltype (word.testmeta)
and insert into another table (word.testwordyy)
desc word.testmeta; Name Null? Type -------------------------------------- FILENAME CHAR(2000) XMLDATA XMLTYPE desc word.testwordyy; Name Null? Type --------------------------------------- ID VARCHAR2(255) KEYWORD VARCHAR2(4000)
and I use xmltable
insert /*+append */ into word.testwordyy(KEYWORD) select /*+ gather_plan_statistics */ dbms_lob.substr(xmltype.getclobval(b.KEWOR),254) from word.testmeta , xmltable ( '$B/mets/KEWOR' passing word.testmeta.XMLDATA as B columns KEWOR xmltype path '/KEWOR/text()' ) b

and the more the number of rows in the word.testmeta table, the more time spent by rank
I have a small simple XML but I need to process a large amount of them (5000000) as well as the treatment is very very slow when the lines of more than 8000
Is there an optimization or the fastest?
Why? Because you do a manipulation of LOB lob.
Your XMLType is the kind of CLOB storage
Your chain of subtr quantities are manipulationg LOB
Altogether, the XML must be done in memory (XMLSEQUENCEFROMXMLTYPE), the manipulation of strings (CLOB) become bigger and bigger and bigger and will eat all your memory and CPU resources.
How to solve it?
Upgrade to a supported database version (11.2.0.3 and upwards)
Store XML documents in a binary XML format of XMLType Securefile
Use simple methods like XMLCAST to make the string conversion and manipulation
Or...
.. m:System.NET.HttpListener.start reading by doing the hard (and today with a version of database not supported), 10.2 through storage XMLType object / relational and convert you CLOB, XMLType storage for storing XMLType object / relational. Use the functions and operators that are created to make the manipulation of strings instead of DBMS_LOB Package (which is not free memory automatically)

I'm currently running SQL Developer 1.5.5. on Windows XP SP2.
Do a SELECT with 1 xmltype column blocks Developer SQL redraw. Table and select ist following the example of code.
The effect is that the sql worksheet is not redrawn. Mouse on the leaves of results brings each column to display except xmltype column.
Anyone can reproduce for my problem?SQL> desc ibb_formulardaten Name Null? Typ ------------------------------ -------------- ID NOT NULL NUMBER(10) FRM_ID NOT NULL NUMBER(10) DATEN XMLTYPE STATUS NOT NULL VARCHAR2(20) SQL> SELECT id, frm_id, daten FROM ibb_formulardaten WHERE id = 12345;
Thanks a lot for any suspicion!
ChristianWhat happens when you run the select statement in SQL * more? It crash?
Post your insert statements. In this way we can verify it is valid xml.
You can try to download new SQL Developer. Maybe something got corrupted on your current installation.

Questions to extract the XMLtype column attributes
I cannot retrieve the values of a column of the XML data type. There are 16 fields and when I try to extract the data the XML snippet is that each of them in 1 great return value. I have tried everything but the problem seems to be that the domain name is an attribute and everything I try fails. I appreciate any help in advance and I'm extremely new XML so please let me know if you need more information.

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.

How to write a query to extract the Application name?
Here, it should return "anais" and "yu123".
I'm using Oracle 11 g.
Thanks in advance.
Something like the following, where TMP_XML. DOC is my XMLType column:
SQL> select x.* 2 from tmp_xml t 3 , xmltable('/Project/Children/Application/Basics' 4 passing t.doc 5 columns application_name varchar2(30) path 'Attribute[@Name="Name"]' 6 ) x 7 ; APPLICATION_NAME ------------------------------ rty yu123 -
Select the column name when the value = something
Is there a way to select the column name when there is a specific value in it?
As follows:
create table (abc123)
COLUMN1 VARCHAR2 (50).
COLUMN2 VARCHAR2 (50).
Column3 varchar2 (50)
);
insert into abc123 values ('yes', 'Yes', 'No');
insert into abc123 values ('no', 'Yes', 'No');
INSERT INTO ABC123 VALUES ('no ',' no', 'No');
insert into abc123 values ('yes', 'Yes', 'Yes');
SELECT CASE WHEN COLUMN1 = 'Yes' THEN - the name of the column would be here somehow?
WHEN COLUMN2 = 'Yes' THEN - the name of the column would be here somehow?
WHERE Column3 = 'Yes' THEN - the name of the column would be here somehow?
Another null
finish as abc123 columnname
final results for the just Column1 would be:
COLUMN1
NULL VALUE
NULL VALUE
COLUMN1
I'm not sure what I use to get the name of column in there
Thank you.

Thanks for posting the CREATE TABLE and INSERT for the sample data.
Don't forget to post the exact results you want from these sample data. If the results depend on the parameters you want to pass a run time, then give a few different examples, with the the desired results of each.
You can hardcode the values you want, such as the column names in a query. For example:
SELECT CASE WHEN column1 = 'Yes' THEN 'Column1' END like y1
CASE WHEN column2 = 'Yes' THEN 'Column2' END like y2
CASE WHEN Column3 = 'Yes' THEN 'Column2' END like y3

XMLTYPE column is PROTECTED or BASIC FILE BINARY?
Hi all
I'm working on tables with XMLTYPE columns, I need to identify tables with the XMLType column and its storage type is basicfile or secure binary files?
Below is an example:
drop table CHB_SECURE;
drop table CHB_BASIC_FILE;
CREATE TABLE CHB_SECURE_FILE
(
IDENTIFICATION NUMBER,
XMLDATA XMLTYPE
)
XMLTYPE COLUMN 'XMLDATA' STORE AS BINARY XML NAVIGATION;
CREATE TABLE CHB_BASIC_FILE
(
IDENTIFICATION NUMBER,
XMLDATA XMLTYPE
)
XMLTYPE COLUMN 'XMLDATA' STORE AS BINARY XML BASICFILE;
When I check the user_tab_cols of view, I found that oracle create new columns with blob types,
SELECT TABLE_NAME, COLUMN_NAME, DATA_TYPE USER_TAB_COLS WHERE TABLE_NAME IN ('CHB_SECURE_FILE', 'CHB_BASIC_FILE');
CHB_BASIC_FILE ID NUMBER CHB_BASIC_FILE XMLDATA XMLTYPE CHB_BASIC_FILE SYS_NC00003$ BLOB OBJECT CHB_SECURE_FILE ID NUMBER CHB_SECURE_FILE XMLDATA XMLTYPE CHB_SECURE_FILE SYS_NC00003$ BLOB OBJECT Select table_name, column_name, segment_name, a.securefile in the user_lobs where table_name IN ('CHB_SECURE_FILE', 'CHB_BASIC_FILE');
TABLE_NAME COLUMN_NAME NOM_SEGMENT SECUREFIL E CHB_BASIC_FILE SYS_NC00003$ SYS_LOB0000768291C00003$ $ NO. CHB_SECURE_FILE SYS_NC00003$ SYS_LOB0000768288C00003$ $ YES In the view of user_lobs, I found that this new addition of columns, I can identify words securefile or not.
But I can not get this information for xmltype columns.
I think that there is a relationship between the column SYS_NC00003$ and my column of xmltype XMLDATA but I can not get this information
Could you please help me?
Thank you
Cherif
I think that there is a relationship between the column SYS_NC00003$ and my column of xmltype XMLDATA but I can not get this information
Yes, there is a relationship.
The XMLType column is a virtual column that points to the hidden BLOB where the data is actually stored as binary XML.
There should be something more simple, but you can use the DBMS_METADATA API to retrieve the information you need:
SQL > select t.table_name, x.*
user_tables 2 t
3, xmltable (xmlnamespaces (default 'http://xmlns.oracle.com/ku'),
"4 ' / TABLE/RELATIONAL_TABLE/TABLE_PROPERTIES/PROPRIETES_COLONNE/COL_LIST/COL_LIST_ITEM [DATATYPE ="XMLTYPE"]"
5 passage xmlparse (document dbms_metadata.get_sxml ('TABLE', t.table_name))
path of varchar2 (30) 6 column column-name 'NAME '.
7 road of varchar2 (5) is_securefile 'exists(XMLTYPE_PROPERTIES/XMLTYPE_STORAGE/LOB_PROPERTIES/STORAGE_TABLE/SECUREFILE) '.
8 ) x
9 where t.table_name in ('CHB_SECURE_FILE', 'CHB_BASIC_FILE')
10;
TABLE_NAME COLUMN_NAME IS_SECUREFILE
------------------------------ ------------------------------ -------------
False CHB_BASIC_FILE XMLDATA
True CHB_SECURE_FILE XMLDATA

Ask about the structured storage of XMLTYPE column in Oracle Xml db
Dear all,
Version of DB: Oracle 11g (11.2.0.3.0)
I have a table with an XMLTYPE column with a structured storage.
CREATE TABLE Orders ( Order_id NUMBER NOT NULL, Order_etc VARCHAR2(100), Order_desc XMLType NOT NULL ) XMLTYPE Order_desc STORE AS OBJECT RELATIONAL XMLSCHEMA "http://localhost/public/xsd/order_desc_xsd.xsd" ELEMENT "OrderState";
I then recorded the XSD XML Db schema that is required for the structured storage.
Before the creation of the table, I had created a table XMLTYPE (db_objects) and was able to use the query to verify that all objects, the XMLTYPE table got broken into when I signed his XSD below.
SELECT column_name, data_type FROM user_tab_cols WHERE table_name = 'DB_OBJECTS';
And used under query to find data stored in the object-relational structure for my table (DB_OBJECTS) created with definition of XMLTYPE.
SELECT EXTRACTVALUE(xseq.column_value, '/THISROW/OWNER') AS owner , EXTRACTVALUE(xseq.column_value, '/THISROW/OBJECT_NAME') AS object_name , EXTRACTVALUE(xseq.column_value, '/THISROW/OBJECT_TYPE') AS object_type , EXTRACTVALUE(xseq.column_value, '/THISROW/OBJECT_ID') AS object_id , EXTRACTVALUE(xseq.column_value, '/THISROW/CREATED') AS created FROM db_objects do , TABLE(XMLSEQUENCE(EXTRACT(VALUE(do), '/ROWSET/THISROW'))) xseq WHERE ROWNUM <= 10;
Now could someone let me know, How to find how the column of XMLTYPE (Order_desc) was divided between other objects, just as I did for the Table with XMLTYPE (as shown above)?
Thank you very much.
First of all, because you are on 11.2, ExtractValue is obsolete and the documentation lists three options to use instead. Here's an (untested) option
SELECT owner, object_name, object_type, object_id, created FROM db_objects do, XMLTable('/ROWSET/THISROW' PASSING do.object_value COLUMNS -- Set data types accordingly owner VARCHAR2(20) PATH 'owner', object_name VARCHAR2(20) PATH 'object_name', object_type VARCHAR2(20) PATH 'object_type', object_id VARCHAR2(20) PATH 'object_id', created VARCHAR2(20) PATH 'created');Secondly, why the column order matter? You store in a method of object / relational. As long as the XML is valid per the schema, Oracle will be able to store the data and thus to retrieve later. How these data are mainly internal Oracle and shouldn't be touched because it can be changed from one version to another. You can use the schema annotation to control how Oracle cards and stores the XML content, but nothing in there specifies the column order I know.
It seems several details are missing information which could help others to answer your question as to what you need.

Insert the ROWNUM in a column of data type of NUMBER table
Hello
I have a table that has a column named "rank" of the NUMBER data type. Basically, I want to make an analysis of top-n and insert the ROWNUM with other columns in the table.
Definition of table1:
CREATE TABLE
(
col1 VARCHAR2 (10),
Col2 NUMBER,
NUMBER of col3,
rank NUMBER
);
INSERT INTO table1
SELECT col1, col2, col3, rownum
DE)
SELECT col1, col2, col3
FROM table2
ORDER BY DESC of col3
)
WHERE rownum < = 5;
I get an error ORA-01722: invalid number. I think the mistake is virtual ROWNUM is not data type of NUMBER, so I tried to cast as CAST (ROWNUM AS NUMBER), but it does not work, same error. Can can you please shed some light on how to convert a ROWNUM number or if the issue is something else.
you're right, your example worked. It is an example of table I just created just to illustrate the problem, but my real table was always showing the same problem. Weird, isn't? However when I added the column names after that insert the question but statement I resolved. Adding code
INSERT INTO TABLE1
(col1, col2, col3, rank) - added
SELECT col1, col2, col3, rownum
DE)
SELECT col1, col2, col3
FROM table2
ORDER BY DESC of col3
)
WHERE rownum<=>
So that means ROWNUM returns number; and another confusion: why the inclusion of the column has solved my problem when it is not necessary for your example. in any case thank you.
