How to insert the data from XML to a table

Question

Hi,
I'm using Oracle 10g Express Edition
I need help in How to insert the data from XML file into the table.
Below is the example i'm working on..
I have create ridb user with below mentioned privileges:
Account Status Locked Unlocked
Default Tablespace: USERS
Temporary Tablespace: TEMP
User Privileges :
Roles:
CONNECT
RESOURCE
Direct Grant System Privileges:
CREATE DATABASE LINK
CREATE MATERIALIZED VIEW
CREATE PROCEDURE
CREATE PUBLIC SYNONYM
CREATE ROLE
CREATE SEQUENCE
CREATE SYNONYM
CREATE TABLE
CREATE TRIGGER
CREATE TYPE
CREATE VIEW
& table is created TRIALZIPCODES below mentioned is the DDL:
CREATE TABLE TRIALZIPCODES
STATE_ABBR VARCHAR2(20) NOT NULL
, ZIP_CODE NUMBER(10, 0) NOT NULL
, ZIP_CODE_EXT VARCHAR2(20)
Below is the XML FILE: which is stored in C:\OracleProject Folder
File name: trial.xml
<?xml version="1.0" ?>
<metadata>
- <Zipcodes>
- <mappings Record="4">
<STATE_ABBREVIATION>CA</STATE_ABBREVIATION>
<ZIPCODE>94301</ZIPCODE>
</mappings>
- <mappings Record="5">
<STATE_ABBREVIATION>CO</STATE_ABBREVIATION>
<ZIPCODE>80323</ZIPCODE>
<ZIP_CODE_EXTN>9277</ZIP_CODE_EXTN>
</mappings>
</Zipcodes>
</metadata>
PL/SQL Procedure:which i'm trying to execute from SQLDeveloper
create or replace
PROCEDURE TRIAL AS
BEGIN
DECLARE
-- declare attributes
charString varchar2(80);
finalStr varchar2(4000) := null;
rowsp integer;
v_FileHandle UTL_FILE.FILE_TYPE;
l_context_handle dbms_xmlgen.ctxHandle;
insCtx DBMS_XMLStore.ctxType;
begin
-- DBMS_XMLGEN.setRowTag ( ctx IN ctxHandle, rowTag IN VARCHAR2);
-- DBMS_XMLGEN.setRowSetTag ( ctx IN ctxHandle, rowSetTag IN VARCHAR2);
-- the name of the table as specified in our DTD
DBMS_XMLGEN.SETROWSETTAG(l_context_handle,'zipcodes');
-- the name of the data set as specified in our DTD
DBMS_xmlgen.setRowTag(l_context_handle,'mappings');
-- for getting the output on the screen
dbms_output.enable(1000000);
-- open the XML document in read only mode
v_FileHandle := utl_file.fopen('c:/OracleProject','trial.xml', 'r');
loop
BEGIN
utl_file.get_line(v_FileHandle, charString);
exception
when no_data_found then
utl_file.fclose(v_FileHandle);
exit;
END;
dbms_output.put_line(charString);
if finalStr is not null then
finalStr := finalStr || charString;
else
finalStr := charString;
end if;
end loop;
-- for inserting the XML data into the table
insCtx := DBMS_XMLSTORE.NEWCONTEXT('RIDB.TRIALZIPCODES');
insCtx := DBMS_XMLSTORE.INSERTXML(insCtx, finalStr);
dbms_output.put_line('INSERT DONE '||TO_CHAR(rowsp));
DBMS_XMLStore.closeContext(insCtx);
END;
END TRIAL;
For the first time when i complied i got the errors as :
Procedure RIDB.PROCEDURE1@RIDB
Error(16,14): PLS-00201: identifier 'UTL_FILE' must be declared
Error(16,14): PL/SQL: Item ignored
Error(29,1): PLS-00320: the declaration of the type of this expression is incomplete or malformed
Error(29,1): PL/SQL: Statement ignored
Error(33,1): PL/SQL: Statement ignored
Error(33,19): PLS-00320: the declaration of the type of this expression is incomplete or malformed
Error(36,1): PL/SQL: Statement ignored
Error(36,17): PLS-00320: the declaration of the type of this expression is incomplete or malformed
So i logged in as sys & grant the permission to execute on UTL_FILE to ridb (user):
SQL Statement:
grant execute on utl_file to ridb
So, it got compiled successfully but when i execute it gives me error as:
Source does not have a runnable target.
What does this mean?
So I browse through forum & i got to know that i need to initial the UTL_FILE_DIR ="C:/OracleProject" in init.ora
So can i edit the init.ora with notepad.When i tried to do that it says permission denied
In my system it shows the init.ora file in path C:\oraclexe\app\oracle\product\10.2.0\server\config\scripts
but there is also other file initXETemp in the same path do i need to do the changes in it.
I have tried even editing the SPFILE as mentioned below:
C:\oraclexe\app\oracle\product\10.2.0\server\dbs\SPFILEEXE - I had edit this file using notepad & set the value of UTL_FILE_DIR ="C:/OracleProject". So next time when i restarted i'm unable to log on to the database.
So i had reinstall the software again.
Could you please let me know how to proceed..

Answer 1

hi,
I have created the directory from sys database
CREATE or replace DIRECTORY XML_DIR2 AS 'C:\OracleProject';
& grant read,write access to the user
grant read,write on directory XML_DIR2 to RIDB;
& i had change the tag name in the xml file as shown below:
<?xml version = '1.0'?>
<metadata>
<Zipcodes>
<mappings Record="4">
<STABBRE>CA</STABBRE>
<ZIPCODE>94301</ZIPCODE>
</mappings>
<mappings Record="5">
<STABBRE>CO</STABBRE>
<ZIPCODE>80323</ZIPCODE>
<ZIPCODEEXT>9277</ZIPCODEEXT>
</mappings>
</Zipcodes>
</metadata>
TRIALZIPCODE table as shown below:
CREATE TABLE "RIDB"."TRIALZIPCODE"
(     "STABBRE" VARCHAR2(20 BYTE),
     "ZIPCODE" NUMBER(*,6) NOT NULL ENABLE,
     "ZIPCODEEXT" NUMBER
) PCTFREE 10 PCTUSED 40 INITRANS 1 MAXTRANS 255 NOCOMPRESS LOGGING
STORAGE(INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645
PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1 BUFFER_POOL DEFAULT)
TABLESPACE "USERS" ;
I have tried two methods as shown below:
Procedure 1:
create or replace
PROCEDURE TRIAL_V2 AS
BEGIN
DECLARE
-- declare attributes
charString varchar2(80);
finalStr varchar2(4000) := null;
rowsp integer;
v_FileHandle UTL_FILE.FILE_TYPE;
l_context_handle dbms_xmlgen.ctxHandle;
insCtx DBMS_XMLStore.ctxType;
cnt NUMBER;
xmldoc xmltype := xmltype( bfilename('XML_DIR2','trialxml.xml'), nls_charset_id('AL32UTF8') );
--XML_DIR VARCHAR2(40) := 'C:\\OracleProject';
BEGIN
insCtx := DBMS_XMLStore.newContext('DEV.TRIALZIPCODES');
DBMS_XMLStore.setUpdateColumn(insCtx, 'STABBRE');
DBMS_XMLStore.setUpdateColumn(insCtx, 'ZIPCODE');
DBMS_XMLStore.setUpdatecolumn(insCtx, 'ZIPCODEEXT');
DBMS_XMLStore.setRowTag(insCtx, 'mappings');
cnt := DBMS_XMLStore.insertXML(insCtx, xmldoc);
DBMS_XMLStore.closeContext(insCtx);
END;
Procedure 1 was compiled with out errors but when i execute i got the error as :
Source does not have a runnable target.
Procedure 2_
CREATE OR REPLACE PROCEDURE TRIAL_V3 AS
BEGIN
DECLARE
-- declare attributes
charString varchar2(80);
finalStr varchar2(4000) := null;
rowsp integer;
v_FileHandle UTL_FILE.FILE_TYPE;
l_context_handle dbms_xmlgen.ctxHandle;
insCtx DBMS_XMLStore.ctxType;
cnt NUMBER;
xmldoc xmltype := xmltype( bfilename('XML_DIR2','trialxml.xml'), nls_charset_id('AL32UTF8') );
--XML_DIR VARCHAR2(40) := 'C:\\OracleProject';
BEGIN
INSERT INTO trialzipcode (STABBRE, ZIPCODE, ZIPCODEEXT)
SELECT extractvalue(x.column_value, 'mappings/STABBRE'),
extractvalue(x.column_value, 'mappings/ZIPCODE'),
extractvalue(x.column_value, 'mappings/ZIPCODEEXT')
FROM TABLE(
XMLSequence(
EXTRACT(
xmltype( bfilename('XML_DIR2','trialxml.xml'), nls_charset_id('AL32UTF8') ),
'metadata/Zipcodes/mappings'
) x
END;
END TRIAL_V3;
Procedure 2 was complied without errors but when i execute i got the error as:
Connecting to the database RIDB.
ORA-22288: file or LOB operation FILEOPEN failed
The system cannot find the file specified.
ORA-06512: at "SYS.DBMS_LOB", line 523

ORA-06512: at "RIDB.TRIAL_V3", line 12
ORA-06512: at line 2
Process exited.
Disconnecting from the database RIDB.
Could you please let me know how to proceed...
