How to ftp a file within PL/SQL procedure?
Hi, all:
Any idea of how to ftp a file within PL/SQL procedure? I have scheduled a job to periodically generate a file and want to ftp this file to another machine. I know crontab can do the ftp part, since we can send email within Oracle, I am wondering whether we can ftp within Oracle as well? Thanks a lot!http://asktom.oracle.com/pls/ask/f?p=4950:8:::::F4950_P8_DISPLAYID:150612348067

How to execute .bat file within pl/sql block
Hi,
I want to execute a batch file (.bat) file withing a pl/sql procedure. Please guide me for it.
RegardsThere are several possible ways to make a call-out from a PL/SQL program to the OS on the database server (but not to the client computer).
You could use java or an external procedure (you'll need to code it in C) for example.
You might be able to make use of UTL_HTTP to talk HTTP to another server or UTL_TCP to talk TCP to another server.

Reading a CSV file with PL/SQL
Hello:
I have a CSV file provided to me by a client. We want to insert the data from this file into a table and perform other processing.
Is it possible to call a CSV file within PL/SQL? If so, how do I begin?
Thanks.Nawneet wrote:
CSV file can load it using SQL loader
go through the below link
http://www.orafaq.com/wiki/SQL*Loader_FAQ
SQL*Loader doesn't work very well in PL/SQL.
Better is External Tables:

Generating Excel file using PL/SQL
Hi,
I wanted to generate the excel file using the below pasted PL/SQL which I have downloaded from one of the tech sites. And as I have very limited knowledge about PL/SQL I really dont know how & where I should compile this below mentioned code and get the desired O/P?
Please reply me ASAP if anybody can help me with this?
Please see the below code and please help me to interpret the same.
CREATE OR REPLACE PACKAGE gen_xl_xml IS
-- Version 0.5
-- Objective : The main objective OF this PACKAGE IS TO CREATE excel files from PL/SQL code
-- Requirement : Excel version 2003 onwards support XML format.
-- The procedures does have TO be called IN specific order at this moment.
-- expected SEQUENCE AS OF now IS
-- At first call create_file -> It creates a FILE WITH NAME that you pass AS parameter. This PROCEDURE writes the
-- excel file header AND some basic requirments like default style.
-- procedures 1. create_style , create_worksheet AND write_cell can be used IN ANY SEQUENCE AS many
-- times AS you need.
-- When done WITH writing TO FILE call the PROCEDURE close_file
-- CLOSE FILE --> This will actually flush the data INTO the worksheet(s) one BY one and then close the file.
-- What colors I can use ?
-- red , blue , green, gray , YELLOW, BROWN , PINK . lightgray ,

k_file constant varchar2(30) := 'YourFile.xls'
begin
create_file(k_file);
-- Call other procedures
close_file;
end;
Don't forget: these procedures are all part of the gen_xl_xml package.
To call them from outside the package, you have to prefix each procedure name with the package name, like this:
declare
k_file constant varchar2(30) := 'YourFile.xls'
begin
gen_xl_xml.create_file(k_file);
-- Call other procedures
gen_xl_xml.close_file;
end; -
How can I load a .xlsx File into a SQL Server Table using a Foreach Loop Container in SSIS?
I know I've REALLY struggled with this before. I just don't understand why this has to be soooooo difficult.
I can very easily do a straight Data Pump of a .xlsX File into a SQL Server Table using a normal Excel Connection and a normal Excel Source...simply converting Unicode to DT_STR and then using an OLE DB Destination of the SQL Server Table.
If I want to make the SSIS Package a little more flexible by allowing multiple .xlsX spreadsheets to be pumped in by using a Foreach Loop Container, the whole SSIS Package seems to go to hell in a hand basket. I simply do the following...
Put the Data Flow Task within the Foreach Loop Container
Add the Variable Mapping Variable User::FilePath that I defined as a Variable and a string within the FOreach Loop Container
I change the Excel Connection and its Expression to be ExcelFilePath ==> @[User::FilePath]
I then try and change the Excel Source and its Data Access Mode to Table Name or view name variable and provide the Variable Name User::FilePath
And that's when I run into trouble...
Exception from HRESULT: 0xC02020E8
Error at Data Flow Task [Excel Source [56]]:SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occured. Error code: 0x80004005.
Error at Data Flow Task [Excel Source [56]]: Opening a rowset for "...(the EXACT Path and .xlsx File Name)...". Check that the object exists in the database. (And I know it's there!!!)
I don't understand by adding a Foreach Loop Container to try and make this as efficient as possible has caused such an error unless I'm overlooking something. I have even tried delaying my validations and that doesn't seem to help.
I have looked hard in Google and even YouTube to try and find a solution for this but for the life of me I cannot seem to find anything on pumping a .xlsX file into SQL Server using a Foreach Loop Container.
Can ANYONE please help me out here? I'm at the end of my rope trying to get this to work. I think the last time I was in this quandry, trying to pump a .xlsX File into a SQL Server Table using a Foreach Loop Container in SSIS, I actually wrote a C# Script
to write the contents of the .xlsX File into a .csv File and then Actually used the .csv File to pump the data into a SQL Server Table.
Thanks for your review and am hoping and praying for a reply and solution.Hi ITBobbyP,
If I understand correctly, you want to load data from multiple sheets in an .xlsx file into a SQL Server table.
If in this scenario, please refer to the following tips:
The Foreach Loop container should be configured as shown below:
Enumerator: Foreach ADO.NET Schema Rowset Enumerator
Connection String: The OLE DB Connection String for the excel file.
Schema: Tables.
In the Variable Mapping, map the variable to Sheet_Name, and change the Index from 0 to 2.
The connection string for Excel Connection Manager is the original one, we needn’t make any change.
Change Table Name or View name to the variable Sheet_Name.
If you want to load data from multiple sheets in multiple .xlsx files into a SQL Server table, please refer to following thread:

Producing text file from PL/SQL procedure (UTL_FILE)?
Hi,
I need to produce a text file from a PL/SQL procedure. My output should be a little over 38K records and my query has 70 fields. I'd like to separate the fields by pipe delimiters in the text file. I can either concatenate all 70 fields into one variable for each record or send all 70 fields over with a pipe, whichever is easier. It looks like I can't spool within PL/SQL but UTL_FILE might be an option from what I'm reading. Does anyone have any good, simple example(s) to produce a text file using this package in calling multiple fields from a LOOP? Our os is UNIX and db is Oracle 9i.
Also, I've read that UTL_FILE has a record output of 1,023 bytes. Is this for each record line or the whole file size? I belive the max # of characters for each line wouldn't exceed 500 characters. The 38K rows I have for the data set would be well over 1MB. If this is the case, is there a work around to produce a larger text file?
Any suggestions and/or examples would be greatly appreciated.
Thanks,
EricAssuming the goal is to create a text file on the database server, you can use UTL_FILE here. Each line can be 1023 characters, but you can have as many lines as you'd like.
Tom Kyte has an example here

How to transfer the tables from one file group to another file group in SQL 2008.?
Hello all,
I have few issues regarding the transfer of the tables from one file group to another file group in SQL 2008 and also How can we backup
and restore the particular database based on file group level.
Let’s say I have a tables stored within the different FG. such as
Tables
File group
Dimension tables
Primary
Fact tables
FG1
FG2…
zzz_tables
DEFAULT_FG
dim.table1 DEFAULT_FG
dim.table2 DEFAULT_FG
Here all I want to transfer the dim.table1 ,dim.table2 from DEFAULT_FG to the Primary File
group .So is there simple methods for transfer the dim.table1,2 from one FG to another .I have tried somewhat but I couldn’t get the exact way .So if someone have better idea please share your knowledge that would be really appreciated.
Secondly after moving those dim.table1 ,dim.table2 from DEFAULT_FG to Primary ,All I want to backup and restore the database only containing the Primary and FG1,FG2… not
a DEFAULT_FG.Is it possible or not.?
Hope to hear from the one who knows better approach for this kind of task .Your simple help will be much appreciated.
Regards,
Anil MaharjanWell after all my full day research on this topic had paid off, I finally got the solution and am so happy to research on these things. It makes
us feel really happy after all our research and hard work doesn't goes as waste.
Finally I got what I am looking for and want to make sure that I am able to transfer the tables from DEFAULT_FG to another FG without tables
having clustered index on that tables .
With the help of the link below I finally got my solution where Roberto’s coded store procedure simply works for this.
Really thanks to him for his great post and thanks to all for your response and your valuable time.

Best way to spool DYNAMIC SQL query to file from PL/SQL
Best way to spool DYNAMIC SQL query to file from PL/SQL [Package], not SqlPlus
I'm looking for suggestions on how to create an output file (fixed width and comma delimited) from a SELECT that is dynamically built. Basically, I've got some tables that are used to define the SELECT and to describe the output format. For instance, one table has the SELECT while another is used to defined the column "formats" (e.g., Column Order, Justification, FormatMask, Default value, min length, ...). The user has an app that they can use to customize the output...which leaving the gathering of the data untouched. I'm trying to keep this formatting and/or default logic out of the actual query. This lead me into a problem.
Example query :
SELECT CONTRACT_ID,PV_ID,START_DATE
FROM CONTRACT
WHERE CONTRACT_ID = <<value>>Customization Table:
CONTRACT_ID : 2,Numeric,Right
PV_ID : 1,Numeric,Mask(0000)
START_DATE : 3,Date,Mask(mm/dd/yyyy)The first value is the kicker (ColumnOrder) as well as the fact that the number of columns is dynamic. Technically, if I could use SqlPlus...then I could just use SPOOL. However, I'm not.
So basically, I'm trying to build a generic routine that can take a SQL string execute the SELECT and map the output using data from another table to a file.
Any suggestions?
Thanks,
JasonYou could build the select statement within PL/SQL and open it using a cursor variable. You could write it to a file using the package 'UTL_FILE'. If you want to display the output using SQL*Plus, you could have an out parameter as a ref cursor.

Dynamic SQL within a SQL Query ?
is there any possibility to do like this ?
SELECT table_name, XXXXXXXX('SELECT Count(*) FROM '||table_name) tot_rows
FROM dba_tables
WHERE owner = 'SCOTT';or any other trick to run dynamic SQL within the SQL Query?
Hoping....that it should be.
Regards,
OrapdevOne small disadvantage: it is executing 202 SQL statements: 3 "user SQL statements" (the one above and the 2 "select count(*)..."), and 199 internal ones ...How did you get to those numbers?
I just traced this statement and found completely different results:

How can i locate the properties files within a ejb container?
when i develop servlet+javabean structure application,in order to imploement decoupling,i
would like to write the config information in the properties files(key-value pair),in
servlet,i use "getResourceAsStream(String relativePath)" method to retrieve the
configuration information from the properties files(i even write the SQL clause
in the files),it alwsys works well.
now,i want to implement such function within the ejb container,that is to read
a properties file from session bean,but i don't know how can i locate the file
within the ejb container by using relative path,i wonder if there is the same
method within ejb container as "getResourceAsStream(.......)" method within servlet
container?
thanks for any helps!
the code snippet is appreciated!In general, you should look at using environment entries (variables) in the
deployment descriptors (both the war and EJB jar rather than properties
files for configuring J2EE applications. The reasons for this are many:
1. This is the official way to do it according to the spec. Properties
files are the J2SE way of doing things
2. As you note, that it's not obvious how you would (legally) read a
properties file inside an EJB.
3. It's consistent between the web and EJB part of your code
4. the weblogic console and tools have good capabilities to edit these
fields.

Hi All,
How can we save the results of a sql query in a html files. Am using HTMLDB.
How to 1. Create HTML files from a sql query in the client drive
2. Store the HTML File into a specified drive (mapped drive)
Kindly help.
Thanks in advanceYou cannot. Not with HTMLDB aka web app server architecture.
The application tier of HTMLDB resides in Oracle. The user connects to the web tier (Apache).
Basic architecture. Web user sends a request to web server. Web server processes the user's request, opens a connections to Oracle and runs the application (HTMLDB) in the Oracle Server.
The application (HTMLDB), within the client-server context, services the web tier. The web tier is its client. The Oracle/HTMLDB server has no idea (and is not interested) in who/where/how/what the web server is in turn servicing. IT IS NOT ITS PROBLEM.
To deliver that file to the user's drive (if that is the requirement), is the problem of the web server. Not the application tier (HTMLDB) that runs on the Oracle Server. Very likely, the Oracle Server will not even be able to communicate directly with the web user - due to proxies, firewalls, and so on.
This is why HTMLDB allows you to design the output of a HTML report to be downloadable as a CSV file. This means that instead of returning a Mime Type of TEXT/HTML to the web server and have the web server passing that along to the web user, it returns TEXT/CSV. The browser is (usually) configured to either save that contents it receives from the web server as a file, or to launch a spreadsheet application (Excel/OpenOffice) to receive that data.
As for submitting a file as a SQL query from a local drive... that is the web user's problem. And the web browser. It needs to have a mechanism in order to provide that file's contents to the web server for processing. The web server talks HTTP - thus that file must be submitted via HTTP. Mapping drives uses NetBIOS as a protocol.. which is something completely different.
And again, this has nothing to do with the HTMLDB application layer inside Oracle (it will process whatever the web server passes to it).
Having clients sharing their drives for write access (in order to allow a server to write to it).. that is truly a Horrible Idea (tm). It will open HUGE security holes in a network. It is contrary to the fundemental principles and concepts of designing web-based systems. -
Find within pl/sql source objects
*
Hello,
do you mean all .sql files on the server or within pl/sql source objects ?
PL/SQL objects like packages are not stored in .sql files but compiled and can be viewed in user_source. So you would have to extract them to a file and execute after changing to get them back into the db. How would you handle this with your version control?
Or do you have sql files stored in CLOBs that are executed? Then you can update them in the database directly.

Using OS Commands within PL/SQL
How can I use Operating system commands from within PL/SQL procedures or functions? Kindly explain with an example.
Thanx,
SBPreviously we have used external procedures to use Windows kernel32.dll to start an external program. However this does not work on Oracle9i.
Instead I have modified an example in Java to acceive this. The following class can start an external program either synchronously or asynchronously and in synchronous mode it will return the programs output.
import java.io.*;
import java.util.*;
public class util
// Executes an operating system command. The command shall be fully qualified.
// The Java connects with silent login. No environment set-up files are run
// and no path is set. The mode can be "sync" or "async" for respectively
// synchronous and asynchronous execution
static public int OSCmd(String cmd, String mode, String[] output)
throws IOException, InterruptedException
System.out.println("OSCmd "+cmd+" ("+mode+")");
output[0]="";
// start command
Process proc = Runtime.getRuntime().exec(cmd);
if (mode.equals("sync"))
// get command's stdout and stderr
InputStream stdout = proc.getInputStream();
InputStream stderr = proc.getErrorStream();
String str;
// Stdout
BufferedReader br = new BufferedReader(new InputStreamReader(stdout));
while ((str = br.readLine()) != null)
output[0]+=str+"\n";
br.close();
// Stderr
br = new BufferedReader(new InputStreamReader(stderr));
while ((str = br.readLine()) != null)
output[0]+=str+"\n";
br.close();
// wait for command to terminate
proc.waitFor();
return proc.exitValue();
return 0;
You need the following permissions:
call dbms_java.grant_permission('COMMON', 'SYS:java.io.FilePermission', '<<ALL FILES>>', 'execute');
call dbms_java.grant_permission('COMMON', 'SYS:java.lang.RuntimePermission', 'writeFileDescriptor', '');
call dbms_java.grant_permission('COMMON', 'SYS:java.lang.RuntimePermission', 'readFileDescriptor', '');
And then create the Java stored procedure:
create or replace function os_cmd2(p_cmd varchar2, p_mode varchar2, p_output in out varchar2) return number
as language java
name 'util.OSCmd(java.lang.String, java.lang.String, java.lang.String[]) return int'; -
Controlling sound of separate html files within the same html page.
I need to allow users to preview audio files for purchasing. I have CF pages that return records form a SQL database. Each record contains the same swf file however, each swf file points to a different mp3 for previews of different audio examples. So far, everything is working fine. My problem is that I need to be able to stop the sound from one swf when I click to play a second swf. The only solutions I see in Flash forums deal with loaded swf files. These are not loaded files they are separate files within a page. The question is: How do control one swf from another swf in the same page. The following items have not worked:
soundChannel.stop();,
soundMixer.stopAll()
