Reading an EXCEL file from Oracle PL/SQL (HP-Unix server)

Hi,
I have the following requirement:
1. Get the EXCEL file from the remote FTP location
2. Read the EXCEL file and convert it into the CSV file format.
3. Put the CSV file into another FTP location.
I need to get all these points done using Oracle PL/SQL procedure.
I am using the Oracle 9i installed in HP-Unix environment.
Please help me in getting this done.
Thanks

Ok, setting up Excel as an External Database connection....
1- Go to Control Panel>Administrative Tools>Data Sources (ODBC)>System DSN and create a data source with appropriate driver. Name it EXCL.
2- In %ORACLE_HOME%\Network\Admin\Tnsnames.ora fie add entry:
EXCL =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.12.0.24)(PORT = 1521))
(CONNECT_DATA =
(SID = EXCL)
(HS = OK)
Here SID is the name of data source that you have just created.
3- In %ORACLE_HOME%\Network\Admin\Listener.ora file add:
(SID_DESC =
(PROGRAM = hsodbc)
(SID_NAME = <hs_sid>)
(ORACLE_HOME = <oracle home>)
under SID_LIST_LISTENER like:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = d:\ORA9DB)
(PROGRAM = extproc)
(SID_DESC =
(GLOBAL_DBNAME = ORA9DB)
(ORACLE_HOME = d:\ORA9DB)
(SID_NAME = ORA9DB)
(SID_DESC =
(PROGRAM = hsodbc)
(SID_NAME = EXCL)
(ORACLE_HOME = D:\ora9db)
Dont forget to reload the listener
c:\> lsnrctl reload
4- In %ORACLE_HOME%\hs\admin create init<HS_SID>.ora. For our sid EXCL we create file initexcl.ora.
In this file set following two parameters:
HS_FDS_CONNECT_INFO = excl
HS_FDS_TRACE_LEVEL = 0
5- Now connect to Oracle database and create database link with following command:
SQL> CREATE DATABASE LINK excl
2 USING 'excl'
3 /
Database link created.
Now you can perform query against this database like you would for any remote database.
SQL> SELECT table_name FROM all_tables@excl;
TABLE_NAME
DEPT
EMP
But you're limited to Windows based servers for this.
As for converting Excel to CSV and doing it yourself. I hope you know the internal format of MS Excel files cos you're gonna need to know it. It would be far easier if the "user" creating the Excel file could save a copy out in CSV format for you and then it's just a case of FTP'ing the file and using external tables to read the data.

Hi,
You are trying to read file wrong way. In the tutorial of Java Excel Api: "JExcelApi can read an Excel spreadsheet from a file stored on the local filesystem or from some input stream.". You are trying to read from file system. So you must get file input stream then you can read it. Please search forums KM file read.

Update Existing Excel File from Oracle DB

The user has an Excel Sheet that they populate manually.
There is a application that pulls data from salesDB.
Target : Eliminate the manual updating process of DB.
Solution:
1.Add a Button o VB .NET application like "Generate Report"
2. Create DB connectivity to that Excel sheet and make it pull values from DB instead of manual entry
So that button should produce an Excel document with updated fields reading from salesDB
Questions
1. Which solution is better?
2. what would be the step by step approach for each solution ?
3. Any link to articles that talk about Excel report generation from Oracle would be great.

Hello,
if you need more than a simple csv file then you can find free tools at
https://xml-spreadsheet.samplecode.oracle.com/ or
https://exceldocumenttype.samplecode.oracle.com/
While they both use a MS XML format they differ in the way they return the output file
- write with utl_file (1)
- return a CLOB (1 and 2)
- directly to a web browser through a PL/SQL DAD (2)
- via a user defined type (2)

Has anybody downloaded the student schema file from oracle pl/sql by benjam

from a newbie:
where is the file for the 3rd edition?

This works for me:
PROCEDURE A_DATA_B( p_ID IN SCHEMA2.TABLE1.ID@dblink%TYPE,
                    p_MATCH IN SCHEMA2.TABLE2.MATCH@dblink%TYPE,
                    p_STATUS IN SCHEMA2.TABLE3.STATUS@dblink%TYPE,
                    p_MSG IN SCHEMA2.TABLE1.MSG@dblink%TYPE,
Alternatively create a synonym for the table (you can't create a synonym for a schema):
create synonym ref_table1 for SCHEMA2.TABLE1.ID@dblink
PROCEDURE A_DATA_B( p_ID IN REF_TABLE1.ID%TYPE,
                    p_MATCH IN REF_TABLE2.MATCH%TYPE,
                    p_STATUS IN REF_TABLE3.STATUS%TYPE,
                    p_MSG IN REF_TABLE1.MSG%TYPE,
but I don't like the idea of depending on a schema in another instance at all.
Can you create a reference set of tables in a schema on the current database, to be the source for the data types?

Display excel file from jsp

hi i am trying to read an excel file from a location on the app server and display it in the browser (ie). the excel file should open up and not display the open/save dialog.
following is the code that i am using. i am not able to get it to work. getting an illegalstateexception and also i am getting all garbage diplayed in the browser. no excel. kindly help.
<%@ page import="java.io.*" contentType="application/vnd.ms-excel"%>
<%@ taglib uri="/WEB-INF/tlds/sapphire.tld" prefix="sapphire" %>
<%@ taglib uri="/WEB-INF/tlds/c.tld" prefix="c" %>
<%
//response.reset();
//response.setHeader("Pragma", "no-cache");
//response.setHeader("Cache-Control", "no-cache");
//response.setDateHeader("Expires", 0L);
ServletOutputStream so = response.getOutputStream();
String filename = "C:\\example1.xls";
String mimetype = "application/vnd.ms-excel";
ByteArrayOutputStream output = new ByteArrayOutputStream();
InputStream in = new BufferedInputStream(new FileInputStream(filename));
byte bytebuff[] = new byte[500];
for(int lengthread = 0; (lengthread = in.read(bytebuff)) != -1;){
output.write(bytebuff, 0, lengthread);
byte data[] = output.toByteArray();
response.setContentType(mimetype);
so.write(data);
in.close();
so.close();
%>

A JSP calls getWriter() by default.
Every time you have a carriage return outside <% %> it gets written to the writer.
The Illegal state exception would be because you are getting the outputStream after the writer.
This is better done in a servlet, but can be done in a JSP, try it with code like this:
<%@ page import="java.io.*" contentType="application/vnd.ms-excel"
%><%@ taglib uri="/WEB-INF/tlds/sapphire.tld" prefix="sapphire"
%><%@ taglib uri="/WEB-INF/tlds/c.tld" prefix="c"
%><%
%> Note that there is no text at all outside of the <% %> (not even carriage returns)
Also, why are you writing to a ByteArrayOutputStream (ie into a memory byte array), and then writing the byte array to the servletoutputstream?
Just put a buffer around the servlet outputstream and write directly to that.
ServletOutputStream so = response.getOutputStream();
BufferedOutputStream output = new ByteArrayOutputStream(so);

Error while reading excel file from application server into internal table.

Hi experts,
My requirement is to read an excel file from application server into internal table.
Hence I have created an excel file fm_test_excel.xls in desktop and uploaded to app server using CG3Z tcode (as BIN file type).
Now in my program I have used :
OPEN DATASET v_filename FOR INPUT IN text mode encoding default.
DO.
READ DATASET v_filename INTO wa_tab.
The statement OPEN DATASET works fine but I get a dump (conversion code page error) at READ DATASET statement.
Error details:
A character set conversion is not possible.
At the conversion of a text from codepage '4110' to codepage '4103':
- a character was found that cannot be displayed in one of the two
codepages;
- or it was detected that this conversion is not supported
The running ABAP program 'Y_READ_FILE' had to be terminated as the conversion
would have produced incorrect data.
The number of characters that could not be displayed (and therefore not
be converted), is 445. If this number is 0, the second error case, as
mentioned above, has occurred.
An exception occurred that is explained in detail below.
The exception, which is assigned to class 'CX_SY_CONVERSION_CODEPAGE', was not
caught and
therefore caused a runtime error.
The reason for the exception is:
Characters are always displayed in only a certain codepage. Many
codepages only define a limited set of characters. If a text from a
codepage should be converted into another codepage, and if this text
contains characters that are not defined in one of the two codepages, a
conversion error occurs.
Moreover, a conversion error can occur if one of the needed codepages
'4110' or '4103' is not known to the system.
If the conversion error occurred at read or write of screen, the file
name was '/usr/sap/read_files/fm_test_excel.xls'. (further information about
the file: "X 549 16896rw-rw----201105170908082011051707480320110517074803")
Also let me know whether this is the proper way of reading excel file from app server, if not please suggest an alternative .
Regards,
Karthik

Hi,
Try to use OPEN DATASET v_filename FOR INPUT IN BINARY mode encoding default. instead of OPEN DATASET v_filename FOR INPUT IN text mode encoding default.
As I think you are uploading the file in BIN format to Application server and trying to open text file.

How can one read a Excel File and Upload into Table using Pl/SQL Code.

How can one read a Excel File and Upload into Table using Pl/SQL Code.
1. Excel File is on My PC.
2. And I want to write a Stored Procedure or Package to do that.
3. DataBase is on Other Server. Client-Server Environment.
4. I am Using Toad or PlSql developer tool.

If you would like to create a package/procedure in order to solve this problem consider using the UTL_FILE in built package, here are a few steps to get you going:
1. Get your DBA to create directory object in oracle using the following command:
create directory TEST_DIR as ‘directory_path’;
Note: This directory is on the server.
2. Grant read,write on directory directory_object_name to username;
You can find out the directory_object_name value from dba_directories view if you are using the system user account.
3. Logon as the user as mentioned above.
Sample code read plain text file code, you can modify this code to suit your need (i.e. read a csv file)
function getData(p_filename in varchar2,
p_filepath in varchar2
) RETURN VARCHAR2 is
input_file utl_file.file_type;
--declare a buffer to read text data
input_buffer varchar2(4000);
begin
--using the UTL_FILE in built package
input_file := utl_file.fopen(p_filepath, p_filename, 'R');
utl_file.get_line(input_file, input_buffer);
--debug
--dbms_output.put_line(input_buffer);
utl_file.fclose(input_file);
--return data
return input_buffer;
end;
Hope this helps.

Uses the library to get UTL_FILE to read a excel file in PL SQL?

Good day.
Someone can give me some code that uses the library to get UTL_FILE to read a excel file in PL SQL?
I intend to use this library because I want to run a script on my machine to treat an excel file without having to make changes on the server.
Thank you.

Thank you.
Ranit's links are useful, you should read them.
Also check out the FAQ on this forum:Re: 5. How do I read or write an Excel file?
UTL_FILE is not the best choice for reading data from Excel files.
It also will not be able to read an Excel file located on your client computer. As with any PL/SQL code on the database, it can only access things that the server itself can see, so that doesn't include hacking across the network, bypassing network security, and hacking into the client computers operating system to read files directly from it's hard disk. This isn't how client server architecture is intended to work.
