Parsing Vector into a Table

Hi all,
Firstly, an advanced thankyou for anyone willing to help.
I'm writing a JSP to display a table from a database, but the bean used passes back a vector (consisiting of more vectors) to the JSP and I have no idea how to parse through said vectors so I can output it to a table.
Here's my code so far:
The (segment of) bean:
     public Vector<Vector<Object>> getAllStock()
                                        throws SQLException
          Vector<Object> row = null;
          Vector<Vector<Object>> rows =
                              new Vector<Vector<Object>>();
          connectToDb();
          try
               results = statement.executeQuery(
                                        "SELECT * FROM Stock");
               while (results.next())
                    row = new Vector<Object>();
                    row.add(results.getString(1));
                    row.add(results.getString(2));
                    row.add(results.getInt(3));
                    row.add(results.getInt(4));
                    row.add(results.getFloat(5));
                    rows.add(row);
          catch (SQLException sqlEx)
               //Error message
          disconnectFromDb();
          return rows;
     }And then the JSP:
<HTML>
    <HEAD>
        <TITLE>The tableName Database Table </TITLE>
    </HEAD>
    <BODY>
        <H1>Displaying full stock list </H1>
        <%
                Vector resultset = stockacc.getAllStock();
        %>
        <TABLE BORDER="1">
            <TR>
                <TH>Stock Code</TH>
                <TH>Stock Desc</TH>
                <TH>Current Level</TH>
                <TH>Reorder Level</TH>
                <TH>Price</TH>
            </TR>
            <% while(resultset.next()){ %>
            <TR>
                <TD> <%= resultset.getString(1) %></td>
                <TD> <%= resultset.getString(2) %></TD>
                <TD> <%= resultset.getString(3) %></TD>
                <TD> <%= resultset.getString(4) %></TD>
                <TD> <%= resultset.getString(5) %></TD>
            </TR>
            <% } %>
        </TABLE>
    </BODY>
</HTML>All help and advice greatly appreciated!

Many thanks for all the timely replies!
I'm trying to implement your solution (stevejluke), and here's what I've got so far:
<HTML>
<%@ page import="java.util.*" %>
<%@ page import="java.net.*" %>
<jsp:useBean id="stockacc" class="stockBeans.StockAccess" />
    <HEAD>
        <TITLE>The tableName Database Table </TITLE>
    </HEAD>
    <BODY>
        <H1>The tableName Database Table </H1>
        <%
               Vector table = (Vector)stockacc.getAllStock();
              Iterator rows = table.iterator();
              Vector currentRow = (Vector)rows.next();
              Iterator columns = currentRow.iterator();
        %>
        <%= columns.next() %>
        <TABLE BORDER="1">
            <TR>
                <TH>Stock Code</TH>
                <TH>Stock Desc</TH>
                <TH>Current Level</TH>
                <TH>Reorder Level</TH>
                <TH>Price</TH>
            </TR>
            <TR>
               </TR>
        </TABLE>
    </BODY>
</HTML>Bearing in mind I'm just trying to see if anythings making it through, hence I'm just using <%= columns.next() %> for now.
However, I don't think the vector (of vectors; not too confusing!) is being created when I do:
Vector table = (Vector)stockacc.getAllStock();As I'm getting a NoSuchElement exception being thrown.
Can anyone advise?
Thanks again.

Python script to parse 'iwlist scan' into a table

Hi,
I've written a small python script that parses the output of the command "iwlist interface scan" into a table.
Why ?
Like many arch linux users I think, I use netcfg instead of something like network manager or wicd. So the most natural way to scan for wifi networks in range is iwlist scan. But the output of this command is huge and I find it difficult to retrieve information. So this script parses it into a table : one network, one line.
Example output
Name Address Quality Channel Encryption
wifi_1 01:23:45:67:89:AB 100 % 11 WPA v.1
wifi_2 01:23:45:67:89:AC 76 % 11 WEP
wifi_3 01:23:45:67:89:AD 51 % 11 Open
wifi_4 01:23:45:67:89:AE 50 % 11 WPA v.1
wifi_5 01:23:45:67:89:AF 43 % 4 Open
wifi_6 01:23:45:67:89:AG 43 % 4 WPA v.1
Details
It reads from stdin so you use it like that: iwlist wlan0 scan | iwlistparse.py
The width of the columns is determined by what's in it.
You can easily do a bit more than just parsing the info: in the example above, the quality has been calculated to percents from a ratio (e.g. 46/70).
It is sorted, too.
Customization
It's python so it's easy to customize. See the comments in the code.

I hope you find it useful. Please report bugs, I haven't tested it a lot. You may have to customize it though, because I think not all iwlist scan outputs are the same. Again, see comments, it should be easy.

This tool is very helpfull. I am trying to add a new function to the existing code to parse the signal level parameter from the output of iwlist wlan0 scan, but I am getting lot of issues .Since I am new to python script can anyone help me to extract the signal level also from the scan put put.
The parametr to be used is Signal level=-44 dBm ,I am trying to create a one more column with Signal level and print its out in the table.
Example:-
Signal level
-44db
The error I am getting
File "iwlist_parser_Testing.py", line 146, in <module>
main()
File "iwlist_parser_Testing.py", line 144, in main

XML into a table??

I am making an application that takes an XML file and puts the content into a table.
I managed to parse the document with a SAX parser so far, but I am not sure how i can put the parsed results into the table, if anyone has done a similar thing, then please help. Some code examples will help a lot.
it is a bit complicated as i will also need a table where its cells can span more than one column.
Where do I begin?
your help is greatly appreciated

How to parse XML Column and insert values into a table

Hello,
I am working on a simple project to demonstrate how to load and extract XML using SQL, I have already made a table that contains a column of XMLTYPE and loaded an XML file into it (code below)
create or replace directory XMLSRC as 'C:\XMLSRC';
drop table Inventory;
create table Inventory(Inv XMLTYPE);
INSERT INTO Inventory VALUES (XMLTYPE(bfilename('XMLSRC', 'Inventory.xml'),nls_charset_id('AL32UTF')));
select * from Inventory;
I now however need to get the XML data back out of that and loaded into a new table. Troubleshooting guides I have read online seem to only be dealing with parsing an external XML document and loading it into a table, and not what I need to do which is parse a column of XML data and load that into a table. The project trivial with simple tables containing only 3 columns.
The table that needs to be loaded is as follows:
create table InventoryOut(PartNumber Number(10), QTY Number(10), WhLocation varchar2(500));
The XML document is as follows:
<?xml version="1.0" encoding="UTF-8"?>
<dataroot xmlns:od="urn:schemas-microsoft-com:officedata" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="Inventory.xsd" generated="2012-04-09T17:36:30">
<Inventory>
<PartNumber>101</PartNumber>
<QTY>12</QTY>
<WhLocation>WA</WhLocation>
</Inventory>
</dataroot>
Thank you for any help you can offer.

First of all, thank you for your help!! Still stunned that you actually took the time to write out an eample using my tables/names/etc. Thank you!!
Attached is the code, there seems to be an issue with referencing the other table, Inventory.Inv, I checked and that table and the Inv column are showing up in the database so I am not sure why it is having issues locating them, take a look at the code I wrote as well as the output (*I included the real version number for you this time :)
EDIT: In your code right here:
select xt.*
3 from Inventory inve,
4 XMLTable('/dataroot/Inventory'
5 PASSING inve.Inv
I think is where I am messing it up, perhaps not understanding fully what is going on, as you write "Inventory inve" and "inve.Inv" ---- Is inve a keyword that I am just not familiar with? I think this is where the issues lies in my code.
END EDIT
EDIT2: Well that looks like it was it, changed that to how you have it and it now works!!! Could you please explain what that few lines is doing, and what the xt.* and inve are doing? Thanks again!!!
END EDIT2
drop table InventoryOut;
create table InventoryOut (PartNumber number(10), QTY number(10), WhLocation varchar2(500));
insert into InventoryOut (PartNumber, QTY, WhLocation)

Can't figure out how to parse JSON list of lists into a table

JSON returned (from google analytics) has an entry like:
"rows": [
        "(none)",
        "148"
        "email",
        "2"
        "organic",
        "183"
        "referral",
        "140"
In Power Query the column heading is "List" and each row has "List" which I can drill into. But I need to instead expand this into a table with 4 rows and 2 columns.

I thought to transform this JSON into XML Spreadsheet format, but I just did a test and Power Query cannot parse Excel XML Spreadsheet files. Frankly I was surprised that it couldn't read it since it is a native Excel format.
If I were to transform my JSON into a format that Power Query can understand and that allows me to specify data types and ideally also formats, what text file formats should I be considering. XML Spreadsheet is the only text file format I know that
allows you to specify data types. But I have a feeling that I am overlooking some other options.
OData would be great except that Power Query insists on also asking for the metadata in a separate call. It would be great if Power Query could RESTify the OData request by either not making the $metadata request (another argument to the OData function?)
or just continuing on if that HTTP call failed.

Parse XML Elements/Attributes from CLOB into Oracle Table

Hi!
I have an XML file (loaded into a CLOB) which I need to parse and have each individual element and attribute inserted into an oracle table for manipulation.
Eg: XML File...
<PERSON>
<PER_ID changed="1">1</PER_ID>
<SURNAME changed="1">MARTIN</SURNAME>
<ADDRESS>
<STREET_NO changed="1">1</STREET_NO>
<POSTCODE changed="1">LE3 8RA</POSTCODE>
</ADDRESS>
</PERSON>
There will only ever be one address.
From this I need to extract
* PER_ID and related changed attribute
* SURNAME and related changed attribute
* STREET_NO and related changed attribute
* POSTCODE and related changed attribute
and insert a single record into the table below:
CREATE TABLE PERSON AS
( PER_ID VARCHAR2(10)
, ID_CHANGED VARCHAR2(1)
, SURNAME VARCHAR2(30)
, ID_CHANGED VARCHAR2(1)
, STREET_NO VARCHAR2(5)
, ID_CHANGED VARCHAR2(1)
, POSTCODE VARCHAR2(10) );
Any assistance/advice would be very much appreciated. I've tried using DBMS_XMLSave / DBMS_XMLStore which works great at pulling in elements (PER_ID, SURNAME, etc) straight into the table but doesn't look at the changed attributes, and I need both.
Thanks a million in advance to anyone who can crack this!!

Not a perfectly framed question. How do you want to load the XML file? Hoping you want to parse the xml file and load it into a table you can do this.
This is the xml file
karthick% cat emp_details.xml
<?xml version="1.0"?>
<ROWSET>
<ROW>
<EMPNO>7782</EMPNO>
<ENAME>CLARK</ENAME>
<JOB>MANAGER</JOB>
<MGR>7839</MGR>
<HIREDATE>09-JUN-1981</HIREDATE>
<SAL>2450</SAL>
<COM>0</COM>
<DEPTNO>10</DEPTNO>
</ROW>
<ROW>
<EMPNO>7839</EMPNO>
<ENAME>KING</ENAME>

<HIREDATE>17-NOV-1981</HIREDATE>
<SAL>5000</SAL>
<COM>0</COM>
<DEPTNO>10</DEPTNO>
</ROW>
</ROWSET>
You can write a query like this.
SQL> select *
2    from xmltable
3         (
4            '/ROWSET/ROW' passing xmltype
5            (

How to load a XML file into a table

Hi,
I've been working on Oracle for many years but for the first time I was asked to load a XML file into a table.
As an example, I've found this on the web, but it doesn't work
Can someone tell me why? I hoped this example could help me.
the file acct.xml is this:
<?xml version="1.0"?>
<ACCOUNT_HEADER_ACK>
<HEADER>
<STATUS_CODE>100</STATUS_CODE>
<STATUS_REMARKS>check</STATUS_REMARKS>
</HEADER>
<DETAILS>
<DETAIL>
<SEGMENT_NUMBER>2</SEGMENT_NUMBER>
<REMARKS>rp polytechnic</REMARKS>
</DETAIL>
<DETAIL>
<SEGMENT_NUMBER>3</SEGMENT_NUMBER>
<REMARKS>rp polytechnic administration</REMARKS>
</DETAIL>
<DETAIL>
<SEGMENT_NUMBER>4</SEGMENT_NUMBER>
<REMARKS>rp polytechnic finance</REMARKS>
</DETAIL>
<DETAIL>
<SEGMENT_NUMBER>5</SEGMENT_NUMBER>
<REMARKS>rp polytechnic logistics</REMARKS>
</DETAIL>
</DETAILS>
<HEADER>
<STATUS_CODE>500</STATUS_CODE>
<STATUS_REMARKS>process exception</STATUS_REMARKS>
</HEADER>
<DETAILS>
<DETAIL>
<SEGMENT_NUMBER>20</SEGMENT_NUMBER>
<REMARKS> base polytechnic</REMARKS>
</DETAIL>
<DETAIL>
<SEGMENT_NUMBER>30</SEGMENT_NUMBER>
</DETAIL>
<DETAIL>
<SEGMENT_NUMBER>40</SEGMENT_NUMBER>
<REMARKS> base polytechnic finance</REMARKS>
</DETAIL>
<DETAIL>
<SEGMENT_NUMBER>50</SEGMENT_NUMBER>
<REMARKS> base polytechnic logistics</REMARKS>
</DETAIL>
</DETAILS>
</ACCOUNT_HEADER_ACK>
For the two tags HEADER and DETAILS I have the table:
create table xxrp_acct_details(
status_code number,
status_remarks varchar2(100),
segment_number number,
remarks varchar2(100)
before I've created a
create directory test_dir as 'c:\esterno'; -- where I have my acct.xml
and after, can you give me a script for loading data by using XMLTABLE?
I've tried this but it doesn't work:
DECLARE
acct_doc xmltype := xmltype( bfilename('TEST_DIR','acct.xml'), nls_charset_id('AL32UTF8') );
BEGIN
insert into xxrp_acct_details (status_code, status_remarks, segment_number, remarks)
select x1.status_code,
        x1.status_remarks,
        x2.segment_number,
        x2.remarks
from xmltable(
'/ACCOUNT_HEADER_ACK/HEADER'
passing acct_doc
columns header_no      for ordinality,
          status_code    number        path 'STATUS_CODE',
          status_remarks varchar2(100) path 'STATUS_REMARKS'
) x1,
xmltable(
'$d/ACCOUNT_HEADER_ACK/DETAILS[$hn]/DETAIL'
passing acct_doc as "d",
          x1.header_no as "hn"
columns segment_number number        path 'SEGMENT_NUMBER',
          remarks        varchar2(100) path 'REMARKS'
) x2
END;
This should allow me to get something like this:
select * from xxrp_acct_details;
Statuscode status remarks segement remarks
100 check 2 rp polytechnic
100 check 3 rp polytechnic administration
100 check 4 rp polytechnic finance
100 check 5 rp polytechnic logistics
500 process exception 20 base polytechnic
500 process exception 30
500 process exception 40 base polytechnic finance
500 process exception 50 base polytechnic logistics
but I get:
Error report:
ORA-06550: line 19, column 11:
PL/SQL: ORA-00932: inconsistent datatypes: expected - got NUMBER
ORA-06550: line 4, column 2:
PL/SQL: SQL Statement ignored
06550. 00000 - "line %s, column %s:\n%s"
*Cause:    Usually a PL/SQL compilation error.
and if I try to change the script without using the column HEADER_NO to keep track of the header rank inside the document:
DECLARE
acct_doc xmltype := xmltype( bfilename('TEST_DIR','acct.xml'), nls_charset_id('AL32UTF8') );
BEGIN
insert into xxrp_acct_details (status_code, status_remarks, segment_number, remarks)
select x1.status_code,
        x1.status_remarks,
        x2.segment_number,
        x2.remarks
from xmltable(
'/ACCOUNT_HEADER_ACK/HEADER'
passing acct_doc
columns status_code    number        path 'STATUS_CODE',
          status_remarks varchar2(100) path 'STATUS_REMARKS'
) x1,
xmltable(
'/ACCOUNT_HEADER_ACK/DETAILS'
passing acct_doc
columns segment_number number        path 'SEGMENT_NUMBER',
          remarks        varchar2(100) path 'REMARKS'
) x2
END;
I get this message:

My oracle version is 10gR2 Express Edition
I do need a script for loading xml files into a table as soon as possible, Give me please a simple example for understanding and that works on 10gR2 Express Edition
Thanks in advance!

The reason your first SQL statement
select x1.status_code,
        x1.status_remarks,
        x2.segment_number,
        x2.remarks
from xmltable(
'/ACCOUNT_HEADER_ACK/HEADER'
passing acct_doc
columns header_no      for ordinality,
          status_code    number        path 'STATUS_CODE',
          status_remarks varchar2(100) path 'STATUS_REMARKS'
) x1,
xmltable(
'$d/ACCOUNT_HEADER_ACK/DETAILS[$hn]/DETAIL'
passing acct_doc as "d",
          x1.header_no as "hn"
columns segment_number number        path 'SEGMENT_NUMBER',
          remarks        varchar2(100) path 'REMARKS'
) x2
returns the error you noticed
PL/SQL: ORA-00932: inconsistent datatypes: expected - got NUMBER
is because Oracle is expecting XML to be passed in. At the moment I forget if it requires a certain format or not, but it is simply expecting the value to be wrapped in simple XML.
Your query actually runs as is on 11.1 as Oracle changed how that functionality worked when 11.1 was released. Your query runs slowly, but it does run.
As you are dealing with groups, is there any way the input XML can be modified to be like
<ACCOUNT_HEADER_ACK>
<ACCOUNT_GROUP>
<HEADER>....</HEADER>
<DETAILS>....</DETAILS>
</ACCOUNT_GROUP>
<ACCOUNT_GROUP>
<HEADER>....</HEADER>
<DETAILS>....</DETAILS>
</ACCOUNT_GROUP>
</ACCOUNT_HEADER_ACK>
so that it is easier to associate a HEADER/DETAILS combination? If so, it would make parsing the XML much easier.
Assuming the answer is no, here is one hack to accomplish your goal
select x1.status_code,
        x1.status_remarks,
        x3.segment_number,
        x3.remarks
from xmltable(
'/ACCOUNT_HEADER_ACK/HEADER'
passing acct_doc
columns header_no      for ordinality,
          status_code    number        path 'STATUS_CODE',
          status_remarks varchar2(100) path 'STATUS_REMARKS'
) x1,
xmltable(
'$d/ACCOUNT_HEADER_ACK/DETAILS'
passing acct_doc as "d",
columns detail_no      for ordinality,
          detail_xml     xmltype       path 'DETAIL'
) x2,
xmltable(
'DETAIL'
passing x2.detail_xml
columns segment_number number        path 'SEGMENT_NUMBER',
          remarks        varchar2(100) path 'REMARKS') x3
WHERE x1.header_no = x2.detail_no;
This follows the approach you started with. Table x1 creates a row for each HEADER node and table x2 creates a row for each DETAILS node. It assumes there is always a one and only one association between the two. I use table x3, which is joined to x2, to parse the many DETAIL nodes. The WHERE clause then joins each header row to the corresponding details row and produces the eight rows you are seeking.
There is another approach that I know of, and that would be using XQuery within the XMLTable. It should require using only one XMLTable but I would have to spend some time coming up with that solution and I can't recall whether restrictions exist in 10gR2 Express Edition compared to what can run in 10.2 Enterprise Edition for XQuery.

How to insert data from APEX form into two tables

Hi,
I'm running APEX 4.1 with Oracle XE 11g, having two tables CERTIFICATES and USER_FILES. Some of the (useless) fields are cut to reduce information:
CREATE TABLE CERTIFICATES
CERT_ID NUMBER NOT NULL ,
CERT_OWNER NUMBER NOT NULL ,
CERT_VENDOR NUMBER NOT NULL ,
CERT_NAME VARCHAR2 (128) ,
CERT_FILE NUMBER NOT NULL ,
) TABLESPACE CP_DATA
LOGGING;
ALTER TABLE CERTIFICATES
ADD CONSTRAINT CERTIFICATES_PK PRIMARY KEY ( CERT_ID ) ;
CREATE TABLE USER_FILES
FILE_ID NUMBER NOT NULL ,
FILENAME VARCHAR2 (128) ,
BLOB_CONTENT BLOB ,
MIMETYPE VARCHAR2 (32) ,
LAST_UPDATE_DATE DATE
) TABLESPACE CP_FILES
LOGGING
LOB ( BLOB_CONTENT ) STORE AS SECUREFILE
TABLESPACE CP_FILES
STORAGE (
PCTINCREASE 0
MINEXTENTS 1
MAXEXTENTS UNLIMITED
FREELISTS 1
BUFFER_POOL DEFAULT
RETENTION
ENABLE STORAGE IN ROW
NOCACHE
ALTER TABLE USER_FILES
ADD CONSTRAINT CERT_FILES_PK PRIMARY KEY ( FILE_ID ) ;
ALTER TABLE CERTIFICATES
ADD CONSTRAINT CERTIFICATES_USER_FILES_FK FOREIGN KEY
CERT_FILE
REFERENCES USER_FILES
FILE_ID
NOT DEFERRABLE
What I'm trying to do is to allow users to fill out all the certificate data and upload a file in an APEX form. Once submitted the file should be uploaded in the USER_FILES table and all the fields along with CERT_ID, which is the foreign key pointing to the file in the USER_FILES table to be populated to the CERTIFICATES table. APEX wizard forms are based on one table and I'm unable to build form on both tables.
That's why I've created a view (V_CERT_FILES) on both tables and using INSTEAD OF trigger to insert/update both tables. I've done this before and updating this kind of views works perfect. Here is where the problem comes, if I'm updating the view all the data is updated correctly, but if I'm inserting into the view all the fields are populated at CERTIFICATES table, but for USER_FILES only the fields FILE_ID and LAST_UPDATE_DATE are populated. The rest three regarding the LOB are missing: BLOB_CONTENT, FILENAME, MIMETYPE. There are no errors when running this from APEX, but If I try to insert into the view from SQLDeveloper, I got this error:
ORA-22816: unsupported feature with RETURNING clause
ORA-06512: at line 1
As far as I know RETURNING clause in not supported in INSTEAD of triggers, although I didn't have any RETURNING clauses in my trigger (body is below).
Now the interesting stuff, after long tracing I found why this is happening:
First, insert is executed and the BLOB along with all its properties are uploaded to wwv_flow_file_objects$.
Then the following insert is executed to populate all the fields except the BLOB and it's properties, rowid is RETURNED, but as we know RETURNING clause is not supported in INSTEAD OF triggers, that's why I got error:
PARSE ERROR #1918608720:len=266 dep=3 uid=48 oct=2 lid=48 tim=1324569863593494 err=22816
INSERT INTO "SVE". "V_CERT_FILES" ( "CERT_ID", "CERT_OWNER", "CERT_VENDOR", "CERT_NAME", "BLOB_CONTENT") VALUES (:B1 ,:B2 ,:B3 ,:B4, ,EMPTY_BLOB()) RETURNING ROWID INTO :O0
CLOSE #1918608720:c=0,e=11,dep=3,type=0,tim=1324569863593909
EXEC #1820672032:c=3000,e=3168,p=0,cr=2,cu=4,mis=0,r=0,dep=2,og=1,plh=0,tim=1324569863593969
ERROR #43:err=22816 tim=1324569863593993
CLOSE #1820672032:c=0,e=43,dep=2,type=1,tim=1324569863594167
Next my trigger gets in action, sequences are generated, CERTIFICATES table is populated and then USER_FILES, but only the FILE_ID and LAST_UPDATE_DATE.
Finally update is fired against my view (V_CERT_FILES), reading data from wwv_flow_files it populates BLOB_CONTENT, MIMETYPE and FILENAME fields at the specific rowid in V_CERT_FILES, the one returned from the insert at the beginning. Last, file is deleted from wwv_flow_files.
I'm using sequences for the primary keys, this is only the body of the INSTEAD OF trigger:
select user_files_seq.nextval into l_file_id from dual;
select certificates_seq.nextval into l_cert_id from dual;
insert into user_files (file_id, filename, blob_content, mimetype, last_update_date) values (l_file_id, :n.filename, :n.blob_content, :n.mimetype, sysdate);
insert into certificates (cert_id, cert_owner, cert_vendor, cert_name, cert_file) values (l_cert_id, :n.cert_owner, :n.cert_vendor, :n.cert_name, l_file_id);
I'm surprised that I wasn't able to find a valuable source of information regarding this problem, only MOS note about running SQLoader against view with CLOB column and INSTEAD OF trigger. The solution would be to ran it against base table, MOS ID 795956.1.
Maybe I'm missing something and that's why I decided to share my problem here. So my question is how do you create this kind of architecture, insert into two tables with a relation between them in APEX ? I read a lot in the Internet, some advices were for creating custom form with APEX API, create a custom ARP, create two ARP or create a PL/SQL procedure for handing the DML?
Thanks in advance.
Regards,
Sve

Thank you however I was wondering if there was an example available which uses EJB and persistence.

Question about reading csv file into internal table

Some one (thanks those nice guys!) in this forum have suggested me to use FM KCD_CSV_FILE_TO_INTERN_CONVERT to read csv file into internal table. However, it can be used to read a local file only.
I would like to ask how can I read a CSV file into internal table from files in application server?
I can't simply use SPLIT as there may be comma in the content. e.g.
"abc","aaa,ab",10,"bbc"
My expected output:
abc
aaa,ab
10
bbb
Thanks again for your help.

Oracle 10g performance degrades while concurrent inserts into a table

Hello Team,
I am trying to insert into single table via multiple threads, Some of these threads perform reasonably well but some will take really longer time, As the time goes on performance drastically degrades (even down by 500 to 600 times). With AWR report i see that there quite huge number of buffer gets there. I am not sure how can i reduce those. If i ran on a single thread this operation is consistent.
I tried quite a few options like
1. Increasing SGA Memory
2. Moving redo logs to another disk drive.
3. Trying it on a empty table
4. Trying it on a table which has huge data (4 Million rows)
5. I have even tried partitioning the table with HASH algoritm
Note: Each thread i am pupming equal amount of data (let say 25K rows).
Can any body suggest me a clue what could be the culprit here.
Thanks in Advance

Read the trace file to find the statement you're interested id - the line above it will be a +"PARSING"+ line, and will include a reference to the statement hash_value look like +'hv=3838377475845'+.
Use the hash_value to query v$sql to get the sql_id and child_number;
Use the sql_id and child number in a call to dbms_xplan.display_cursor:
PARSING IN CURSOR #7 len=68 dep=0 uid=55 oct=3 lid=55 tim=448839952404 *hv=3413100263* ad='2f6ede48'
select ... etc. (the statement I want the plan for)
SQL> select sql_id , child_number from v$sql where hash_value = *3413100263*;

SQL*Loader-929: Error parsing insert statement for table

Hi,
I get the following error with SQL*Loader:
Table MYTABLE loaded from every logical record.

SQL*Loader-929: Error parsing insert statement for table MYTABLE.
ORA-01031: insufficient privileges
I am positive that I can SELECT the sequence and INSERT into the table with the user invoking sql*loader.
Where does that "ORA-01031" come from?
Regards
...

Options:
1) you are wrong about privileges OR
2) you have the privilege only when you connect via SQL*Plus (or whichever other tool you used to test the insert).
Is it possible that during your test you enabled the role which granted you the INSERT privilege - and that SQL*Loader doesn't do this?
Can you see the table in this list?
select *
from user_tab_privs_recd
where table_name='MY_TABLE'
and owner='table owner whoever';
select *
from user_role_privs;Any roles where DEFAULT_ROLE is not YES?

Upload .txt file into Database Table

Hi,
I was wondering if someone could please point me in the right direction. I've been looking around the forum but can't find anything to help me achieve the following.
I would like to be able to upload a .txt file using a webpage. Then store the information inside this file into database tables.
eg. contents of mytextfile.txt:
richard
10 anywhere street, anytown, somewhere
111 222 333 444
joe
9 somestreet, elsewhere
999 888 777 666
peter
214 nearby lane, overhere
555 555 555 555
I would like to insert this data into a table.
eg. table name = CONTACTS
userid = primary key (using sequence)
username = (line 1 - richard, joe, peter)
address = (line 2)
phone_no = (line 3)
As you can see the records will appear 1 at a time and will have a blank line between records. Is there anyway for me to upload a file like this and have it placed into tables?
I have seen http://otn.oracle.com/products/database/htmldb/howtos/howto_file_upload.html but this seems to be for uploading a whole file and downloading the same file, rather than extracting data from the file.
I hope I have managed to explain my problem.
Many thanks,
Richard.

Richard,
HTML DB allows you to upload CSV files via the Data Workshop. That data would then be parsed and inserted into a specific table. Alternatively, if you have your data in an Excel spreadsheet, and it is less than 32k, you can copy & paste the data directly into HTML DB's Data Workshop, which will then parse and import it into the Oracle database.
The one obstacle you may have to overcome is converting your data from the format you outlined to CSV format. Specifically, you would have to make this:
richard
10 anywhere street, anytown, somewhere
111 222 333 444
Look something like this:
"richard","10 anywhere street, anytown, somewhere","111 222 333 444"
Hope this helps,
- Scott -
