The xml is very long. For inserting into the table I am using xmlparse() function to get XMLType.
While doing this I am getting ORA-01704: string literal too long error. It says can accommodate at the most 4000 characters.
I guess XMLType is stored as a CLOB by default.So it should allow more than 4000 characters.
How can I store xml with more than 4000 characters.
Thanks.
XMLParse is a SQL function, so you can't use a string literal longer than 4000 chars.
Instead, you may declare a PL/SQL VARCHAR2 variable, which can hold up to 32k characters, and then use the XMLType constructor :
DECLARE
xmlstr VARCHAR2(32767) := '<xml string here>';
xmldoc xmltype;
BEGIN
xmldoc := xmltype(xmlstr);
INSERT INTO your_table(xml_data) VALUES(xmldoc);
END;For strings longer than 32k, you'll probably have to load it from a file.

Don't rely on this value, it's wrong.
XMLType datatype inherits the properties of its underlying LOB storage, in the present case CLOB, which can store TBs of data. -
[11g] most efficient way to calculate size of xmltype type column
I need to check the current size of some xmltype column in a BIU trigger.
I don't think it's good to use
length(:new.xml_data.GetStringVal());
or
dbms_lob.GetLength(:new.xml_data.GetClobVal());
What's the most efficient way to get the storage size?
I don't need the string serialized size.
It could also be the internal storage size (incl. administration data overhead).
- thanks!
regards,
Frank> May I ask for what reason you need to know it?
I need to handle very large XML document output, which currently hits the internal xmltype limitation of 4GByte, when aggregating XML document fragments for this.

I don't use dedicated storage clause.
But i am hitting the problem already for aggregation into some xmltype variable in PL/SQL
- BEFORE writing back to a result table.
Can i avoid such problems, when writing to a table DIRECTLY w/o intermediate xmltype PL/SQL variable
- depending on the storage clause?
The reason why asking how to get the size of some xmltype (in table column and/or in PL/SQL variable) is, that i am thinking of a threshold detection.
In case threshold is reached: outsource XML fragment so far to some separate CLOB storage, and insert a smaller meta-information reference representing that in the output document.
Finally leave up to the client system to use <xs:include> (or alike) to construct the complete document.

Find size of table with XMLTYPE column STORE AS BINARY XML
Hi,
I have a table with structure as:
CREATE TABLE XML_TABLE_1
ID NUMBER NOT NULL,
SOURCE VARCHAR2(255 CHAR) NOT NULL,
XML_TEXT SYS.XMLTYPE,
CREATION_DATE TIMESTAMP(6) NOT NULL
XMLTYPE XML_TEXT STORE AS BINARY XML (
TABLESPACE Tablespace1_LOB
DISABLE STORAGE IN ROW
CHUNK 16384
RETENTION
CACHE READS
NOLOGGING)
ALLOW NONSCHEMA
DISALLOW ANYSCHEMA
TABLESPACE Tablespace2_DATA
- So HOW do I find the total size occupied by this table. Does BINARY storage work as LOB storage. i.e. I need to consider USER_LOBS as well for this.
OR foll. will work
select segment_name as tablename, sum(bytes/ (1024 * 1024 * 1024 )) as tablesize_in_GB
From dba_segments
where segment_name = 'XML_TABLE_1'
and OWNER = 'SCHEMANAME'
group by segment_name ;
- Also if I am copying it to another table of same structure as:
Insert /*+ append */ into XML_TABLE_2 Select * from XML_TABLE_1.
Then how much space in ROllbackSegment do I need. Is it equal to the size of the table XML_TABLE_1?
Thanks..I think foll query calculates it right while including the LOB storage as:
SELECT SUM(bytes)/1024/1024/1024 gb
FROM dba_segments
WHERE (owner = 'SCHEMA_NAME' and
segment_name = 'TABLE_NAME')
OR (owner, segment_name) IN (
SELECT owner, segment_name
FROM dba_lobs
WHERE owner = 'SCHEMA_NAME'
AND table_name = 'TABLE_NAME')
It's 80 GB for our Table with XMLType Column.
But for the second point:
Do we need 80GB of UNDO/ROLLBACK Segment for performing:
Insert /*+ append */ into TableName1 Select * from TableName;
Thanks.. -
What is the default size of icons on desktop?
For some reason after installing an application update all the icons on my desktop are now 16X16. What was the default size that came with the OS and what would have changed that setting?
48x48 is the default. I don't know why the setting might have changed, though.

LPX-00004 - Problems while inserting xml files in a xmltype column
I've faced two problems while trying to insert xml files into my table containing a xmltype column:
create table xml_test (id number(20),content xmltype)
I use following java code for writing xml docs into db:
conn.setAutoCommit(false);
OraclePreparedStatement stmt = (OraclePreparedStatement)
conn.prepareStatement("INSERT INTO xml_test (id,content) VALUES(?,?)");
File file = new File(file1);
InputStream in1 = new FileInputStream(file1);
Reader r1 = new BufferedReader(new InputStreamReader(in1, "UTF-8"));
int len = 0;
StringBuffer text = new StringBuffer();
while ((len = r1.read()) != -1) {
text.append((char) len);
in1.close();
r1.close();
XMLType poXML1 = XMLType.createXML(conn, text.toString());
for (int i = 1; i <= 1; i++) {
stmt.setInt(1, i);
stmt.setObject(2, poXML1);
stmt.execute();
conn.commit();
1. problem: occures only if a xml schema has been assoicated to the specific xmltype column. it seems that the length of a specific xml tag in the document is limited. but why?

You can specify that you wish this column to be mapped as a CLOB in your schema if this is the problem. Also note that there is a 64K limit on the size of an individual node in XMLType. -

/Elements that occur at most once in each document can be indexed using extractValue(). Despite the fact that the index appears to be a functional index, when we create the index we automatically re-write the create index into a normal btree index on the column that contains the value for the element identified by the xpath.
Eg in the case of a functional index based on extractValue, defined on XMLType using Object relational storage, with an xpath that identifies a node that occurs at most once in each document is not a functional index, it's re-written into a plain old vanilla btree index. You can actually check this by looking in the system tables
Eg
SQL> connect system/oracle
Connected.
SQL> select table_name, index_name from all_indexes where owner = 'OE' and table_name = 'PURCHASEORDER';
TABLE_NAME INDEX_NAME

2 /
no rows selectedFrom the above we can see that the index created on extractValue has been re-written in a plain old vanilla BTREE index, and there is no definition for it in dba_ind_expressions So assuming you were able to create the index and insert the data you should find that your index is not a functional index.

XMLType column based on XML Schema: several questions
Hi,
I've a table on an oracle db version 10.1.0.4 where I stage the xml files containing orders created on a third party's system using BizTalk.
Although the storage I opted for is based on an XML Schema, defined by this third-party, I am facing big perfomance issues with files bigger than a few hundreds of kBs.
For instance, a 32Mb file takes more than 2 hours to be processed.
Now, after reading other threads in this forum and the documentation, my understanding of the problem is that the whole issue is with the correct indexing of the nested tables.
Here is my current XML Schema definition:
<?xml version="1.0" encoding="UTF-8"?>

When I registered the XMLSchema, the following types and tables were automatically created and you can see the hierarchy below:
(by the way, I could not find any xdb_utilities.printNestedTables mentioned elsewhere)
XML_ORDERS
|_PickData381_T
|___ProdRun382_T
|_____PickWave388_COLL
|_______PickWave383_T
|_________Customer387_COLL
|___________Customer384_T
|_____________InvOrder386_COLL
These objects are then used in the following nested tables:
TABLE_NAME TABLE_TYPE_NAME PARENT_TABLE_NAME PARENT_TABLE_COLUMN
SYS_NTaK/5zar5S0WitSsgu6OKPQ== PickWave388_COLL PickData389_TAB "XMLDATA"."ProdRun"."PickWave"

Note that I cancelled this operation before it was over so I imagine that these figures refer to the statistics as of the time when the operation was interrupted.
So, here are finally my questions.
In order to create the constraints on the nested tables as shown in other threads, do I need to drop the existing xml_orders table and ancillary object types and recreate them or is there a way to add such constraints using the existing system generated object names?
Secondly, the xml_orders table may contain severale documents, not just one and his current primary key is the column ID. So, in order to uniquely identify the deepest element in the xml document, I need first to select the relevant document by means of the id column.
Would it be better to create the indexes containing this id column together with the nested_table_id and array_index?
Thanks for you help.

PS: I wrote a 10 lines xsl transformation that I passed on to Saxon together with the 32Mb file. It took less than 1 minute to produce a flat file that was loaded almost instantly by SQL*Loader. So, what I am looking for is a procedure loading this stuff in less than 2 minutes or possibly less.Does the following help

How to create index on XMLType column extension?
I have an XMLType column named "info" whose corresponding global element has a complexType "InfoType" in namespace "http://example.org/ord". The "InfoType" complexType is extended in two namespaces, "http://example.org/info/zipcode" and "http://example.org/info/street". How do I create a unique index using an "InfoType" element contributed from one of the extension namespaces?
I have included below a SQL script that completely describes the problem.
Thanks in advance for your assistance?

SQL>In you solution a functional index was created. In my case, by breaking the XML abstraction, and using object-relational SQL to create the index (DDL statements are the one case where I feel this is acceptable) I was able to create a pure B-TREE index which has the same effect.. -
Just bought a new imac Retina and still quite new to Mac in general. But everything works fine so far and I find most answers to my newbie questions online somewhere.
There is one quite annoying thing I could not solve so far:
My finder window always opens in the same small size. All things I found online to save a new default size did not work.
I tried closing it and reopen without success. I tried the same with pressing ctrl or alt or cmd or with resizing it while holding ctrl or alt. No change. As soon as I close it and reopen it opens in the unwanted small "default size"
What else can I try to change this default to the size of my choice ?
Greetings from Switzerland
HolgerTry this - Open a new Finder window, adjust its size and column width, now minimize the window (Apple + 'M'), then click on it from the dock to bring it back, then close it ...and now when you open a new window it should maintain all your recent settings.

I want to create a B*Tree XML Index on the above table for the following:
1. CN
2. TN
in the above schema.
Following the doc, this is what I am issuing:
SQL> CREATE INDEX audt_audit_idx1 ON TST_AUDIT_TBL(CHANGE_HISTORY) INDEXTYPE IS XDB.XMLINDEX PARAMETERS ('XMLTABLE IXTAB

Not sure what is going wrong (and what would be a working xmlindex will look like?)Here goes...
1) Schema registration

end;
2) Table creation
CREATE TABLE TST_AUDIT_TBL
NOTE VARCHAR2(25 CHAR) null,
CHANGE_HISTORY XMLTYPE not null,
CHANGE_HISTORY_EXT XMLTYPE null
XMLTYPE COLUMN CHANGE_HISTORY STORE AS OBJECT RELATIONAL XMLSCHEMA "http://www.oracle.com/a.xsd" element "A"
XMLTYPE COLUMN CHANGE_HISTORY_EXT STORE AS CLOB XMLSCHEMA "http://www.oracle.com/a.xsd" element "AX"
3) Retrieving the nested table and column related to the target element :
SQL> select dbms_xmlstorage_manage.xpath2TabColMapping(
2 owner_name => 'DEV'
3 , table_name => 'TST_AUDIT_TBL'
4 , column_name => 'CHANGE_HISTORY'
5 , xpath => '/A/T/TL/C/CN'
6 , namespaces =>'default ''http://www.oracle.com/a.xsd'''
7 )
8 from dual;
DBMS_XMLSTORAGE_MANAGE.XPATH2T
<Result>
<Mapping TableName="SYS_NTr0U7dPWyRu6OVvDN2f5HEg==" ColumnName="CN"/>
</Result>
4) Creating the index :
SQL> create index CHANGE_HISTORY_IX1 on "SYS_NTr0U7dPWyRu6OVvDN2f5HEg==" ("CN");
Index created
If you're going to create multiple indexes like this, you could really benefit from renaming all the nested tables to meaningful names. That can be done via DBMS_XMLSTORAGE_MANAGE as well. -
Inserting XML data into xmltype column
Oracle version: 10.1.0.5
OpenVms Alpha V8.3
1) Tried this and get the error shown below. Removed charset and placed a zero. Same error.
INSERT INTO xml_demo (xml_data) -- column of xmltype
VALUES
xmltype
bfilename('XML_DIR', 'MOL.XML'),
nls_charset_id('AL32UTF8')
ORA-22993: specified input amount is greater than actual source amount
ORA-06512: at "SYS.DBMS_LOB", line 637
ORA-06512: at "SYS.XMLTYPE", line 283
ORA-06512: at line 1
2) This PL/SQL block works. However maximum raw size around 32K. The file can be around 100K. May be I can load it into a table of raw and somehow concatnate it to insert. Not sure whether this is possible but I am sure there must me a simple way of doing this.
Subset of the xml file is pasted below.
set serveroutput on size 1000000
DECLARE
file1 bfile;
v_xml XMLType;
len1 number(6);
v_rec1 raw(32000);
BEGIN
file1 := bfilename('XML_DIR','MOL.XML');
DBMS_LOB.fileopen(file1, DBMS_LOB.file_readonly);
len1 := DBMS_LOB.getLength(file1);
v_rec1 := dbms_lob.substr(file1,len1,1);
v_xml := xmltype(UTL_RAW.CAST_TO_VARCHAR2(v_rec1));
INSERT INTO xml_demo (xml_data) VALUES (v_xml);
COMMIT;
DBMS_LOB.fileclose(file1);
exception
when others then
dbms_output.put_LINE (sqlerrm);
DBMS_LOB.fileclose(file1);

Thanks. I understand what you are saying. I have been copying files in binary mode from NT servers into VMS. I have to get a proper xml file via FTP from the originating system to further investigate.
I have one last item i need help on. If anything looks obvious let me know:

<Resolution v="PT60M"/>
<Interval>
<Pos v="1"/>
<Qty v="50"/>
<EnergyPrice v="50.45"/>
</Interval>
+4) When I do the load:+
the EnergyPrice is saved in the xmltype column as <EnergyPrice v="50"/>
Losing its decimal value of .45
+5) When I select as follows:+
**DEV** SQL>> l
1 SELECT
2 EXTRACTVALUE(x2.column_value,'/MolTimeSeries/Period/Interval/EnergyPrice/@v') v1,

10 ) x2
11* WHERE EXISTSNODE(x.xml_payload,'/MolDocument/DocumentIdentification[@v="MOL_20100331_1500_1600"]') = 1
+6) get the result+

+7) XDB$RAW_LIST_T('1301000000'),+
Does that tell what I am doing wrong? -
How to create index on xmltype column
I have a table having only one column xmlcontent (xmltype). This table stores xml data of about 10GB size. I'm using extract value to move the data to staging tables.
How can I create index on xmltype column?
Create index indexname on table (column) doesn't seem to work.
Sample xmlstructure is given below
<Root>
<Type>Insert</Type>
<Date>2006-12-29</Date>
<Source>8</Source>
<id>data</id>
<key_flds>
<fld><id>Key1</id><val>C</val></fld>
<fld><id>Key2</id><val>429672</val></fld>
<fld><id>Key3</id><val>8</val></fld>
</key_flds>
</Root>
I need to do extract value on all tags and move them to corresponding relational tables.Hi, you need to create them using something like this (what I have used and work rather well - if I did not load the xml into an xml table, the processing took about 10 minutes, while the indexed xml table took just a few seconds). statute_xml is the table name and sxmldoc is the xml column/field.
create index desc_idx on statute_xml
(sxmldoc.existsNode('/SimpleTypeCompanion/EnumerationValue/@description'))
create index sid_idx on statute_xml
(sxmldoc.existsNode
('/SimpleTypeCompanion/EnumerationValue/Text')
create index effdate_idx on statute_xml
(sxmldoc.existsNode
('/SimpleTypeCompanion/EnumerationValue/@effectiveDate')
Hope this helps.
Ben -

When I run select extractvalue(CCD_DOC, 'recordTarget/patientRole/patient/name/family') from CCD; no errors are returned but I also don't get the value. What am I missing?In a word - namespace definitions...
Here's an example written using XMLQuery, rather than extractValue, which is the preferred approach in 10.2.x and later...

Impdp, XMLType column and ora-26093
Hello!
I have some problem with importing XMLType columns with data longer than 2000 symbols.
Oracle Database 11g Enterprise Edition Release 11.1.0.7.0 - 64bit Production
test data:
create table some_tab (id varchar2(10), xml XMLType);
insert into some_tab values('short', XMLType('<foo></foo>'));
-- we use clob to pass more than 2000 symbols
declare
c clob := '<x> || lpad('</x>', 2700, 'a');
begin
insert into some_tab values('long', XMLType(c));
end;
then I export data with expdp...
and if I import dump into other schema on the same server - that's ok,
BUT if I import data into schema on other server - I have this error:
KUP-11007: conversion error loading table ......
ORA-26093: input data column size (2707) exceeds the maximum input size (2000)
KUP-11009: data for row: ....
what I'm doing wrong?

DATAPUMP NOT IMPORTING XMLTYPE OBJECTS. ORA-26093
Currently no workaround is available for this, although 11gR2 should have it fixed.
