File Properties using PL-SQL

Hi Experts,
Basically we have a data source that is in the form of an external file(.csv). So we are trying to automate a process. If any new .csv file appears in the Directory, then automatically a procedure/function is called.
Now, the job will be executed only if the already existing file has new set of data. Hence i found a way to identify that whether its a new or an exisiting file. The last modified date of the file will change *(On Windows, in Directory if we view all the details of the list we get modified date,size etc...)*
However, I am unable to find the way to retrieve its modified-date using pl-sql.
Could anyone please help me...

The load can complete first (and likely with the last line as a bad row) and only load the file partially.

However, I am unable to find the way to retrieve its modified-date using pl-sql. Not a robust approach. It can be done (determining the file properties, including time stamps) using a Java stored proc for example, than can be called from PL/SQL.
However, I would be hesitant to implement this approach into production as it is not robust enough. How is that file delivered? Why can't the delivery process not inform Oracle that the file needs to be loaded? Why can't the deliver process not start SQL*Loader and drive the load process instead?
I would rather be looking at making that file delivery process intelligent - instead of attempting to "detect" new or changed files from PL/SQL.

Extracting compressed file (zip) using PL/SQL

Hi!
Can anyone help me on how to extract data out of a compressed file(ZIP) using pl sql.

Can anyone help me on how to extract data out of a compressed file(ZIP) using pl sql.Bear in mind that the Lempel-Zif-Welch (LZW) compression used in zip files may still have patent issue relating to Unisys (not sure of the patent has expired now or what, it's always been somewhat confusing). So, if you already have software written to zip/unzip files you should use that as it should be licenced already. If you write your own LZW compression/decompression routine for use in any commercial software you may be required to register and submit royalties to Unisys for the privilege. As I say, I don't know the latest, so you may be ok, but it's something to be aware of and check out if you intend to write your own and it's for commercial reasons.

Can you edit file properties using Labview?

Except for the file attributes like 'read-only' and 'hidden', Windows 2000 & XP also have file properties like 'keywords', 'comments' and 'description'.
Is there any way that I can edit these properties in Labview?

RichElswick wrote:
nope, we never got that far and I am no longer on that project.
And it would be a bitch to implement. Basically those properties are implement using propertysheet handlers. That are shell extensions that can be installed in Windows and in the registry added to one or more file types. On loading the property dialog the shell (basically only an Explorer thing) sees that for that specific file type there are property sheet handlers registered and then loads them as an extra property sheet into the dialog.
There is no common API to retrieve and lets forget about changing the information those property sheet handlers deal with programmatically. And every property sheet handler retrieves the actual properties according to his own private information, such as image properties in JPG files but possible also extra information in the meta data of a file on advanced files systems such as NTFS (the security property sheet for instance).
So you would have to create a Windows dialog, load the according property sheet handlers into it and then have the user deal with that interactively. I doubt that this is what you want.

Want To Capture The File name Using the SQL Loader

Hi,
I Am loading The Data To Staging Table Using The SQL*developer, The File That need to be Loaded Will be One Of The Input To the SQL*Loader Concurrent Program.
In One Of The Column Of My staging Table I want To Put The File name.
Can We do the Same.
thanks,
Ankit

Not unless you generate the loader controlfile dynamically.. try this.. pass file name as $1 first parameter. Use the below example and modify as per your requirement
1) create table with following table structure
create table temp_table (x varchar2(20),file_name varchar2(30));
2) create data file - test.dat (contains only values for x)
abc
def
geh
ggg
fff
3) create a host file host file - test.sh with following content:
echo "load data
infile $1
append
into table temp_table
fields terminated by ','
(x,
file_name constant "$1")" > test.ctl
sqlldr <usr>/<pwd>control=test.ctl
4) run the host file from unix prompt with data file name as parameter (ensure test.sh has execute permissions)
test.sh test.dat
Hope this helps

File upload use pl/sql with OAS 4082 and 8i/EE

is there any way to upload/download files (any format) from web browser use FORM and above env. Don't mention samples in OAS document, it simply doesn't work. thanks.

I probably wrong but I interpret this as POST is not supported, http://download.oracle.com/docs/cd/E11882_01/appdev.112/e16659/xdb22pro.htm#ADXDB5550, "Supported HTTP(S) Client Methods"
It says:
"+The semantics of these HTTP(S) methods is in accordance with WebDAV. Servlets and *Web services may support additional HTTP(S) methods*, such as POST.+" (my emphasis - so yes, it is supported).
Today we are using an Appserver with HTTP mod_plsql, the code for the form looks like:
htp.formopen (
curl => 'FileUpload',
cmethod => 'POST',
cenctype => 'multipart/form-data');
the "FileUpload" takes care of the file and inserts it in the dbThe question is how does it do it? A file upload via mod_plsql/EPG is done via the PLSQL document table. It, mod_plsql/EPG, takes cares of the actual upload part - reading the Mime stream of the upload from the browser and inserting it into the document table.
Unfortunately, seems that the 11g documentation lacks details in this regard. Please consult the Oracle® HTTP Server mod_plsql User's Guide (10g).
<li>section 1.7.1 describes the format of the upload table you need to define
<li>section 1.7.4 shows a sample HTML form doing a HTTP post, and the post-process upload PL/SQL procedure that needs to be written to process the contents of the row just created for the uploaded file in the document table

Hi SSISJoost,
I am so glad you responded to this thread. You are absolutely right. I copied the entire code including the project name (guid) and that solved the error problem.
Now, what did you do to get the message box? I added the watch and I could see the values but how do I get these values in a table? If I remember correctly, in your blog, you mentioned something about using derived columns. I am familiar with Derived Columns
but how do I do that? I appreciate your response.
Thank you.

I used a second script task to show all variable values. It has a
MessageBox in it and between all
variables I added a
newline to make it more readable...
But with an Execute SQL Task and parameters you can also put these values in a Table... or you can read the file in a Data Flow Task and add those variables (as metadata) to each record with a Derived Column

Author metadata separated by semi-colons truncated in file properties and "Get Info"

I'm using Acrobat Professional 9.0 (CS3) for Mac to edit the metadata for a collection of PDFs to be made available on the web. When I enter the data, I am inputting a list of authors separated by commas, like this: Smith J, Watson C, Brown J. If I click on "Additional metadata", the data I've already entered is transposed into the various XMP fields. And the commas separating the author names are changed to semi-colons. I gather that this happens because XMP wants to separate multiple authors with semi-colons, and Acrobat wants the metadata in XMP fields to match the metadata stored for the file properties. Fine.
However, if I save such a PDF and then use Get Info on my Mac (OSX 10.4) to look at the file properties, the list of authors is now truncated where the first semi-colon appears. The list is also truncated in Windows XP if I right-click and select properties. The list is also truncated when I look at the file properties in Preview on my Mac, or if I look at file properties using FoxIT, or using Adobe Acrobat Reader 7 or earlier. The only way a site visitor will actually be able to view the full list of authors in a file saved this way is to use Adobe Reader version 8 or later.
I would like to preserve XMP/Dublin Core/etc metadata in the proper format in the XMP code, but would also like users of standard, popular file viewers to be able to access the full list of authors. Is there a way to do this with Acrobat 9?
Also, once I've saved a file and the XMP metadata has been altered, Acrobat seems to permanently change the way that the authors are listed in the file properties. I cannot manually change those settings any longer without Acrobat overriding my changes and converting commas to semi-colons, or surrounding the entire list of authors in quotation marks. Is there a way to get around these Acrobat overrides and manually take control of my metadata again?
Does Windows Vista read the authors list correctly in the file properties if it is separated by semi-colons?
It seems to me that in an attempt to get XMP metadata working smoothly across the entire CS line, Adobe has jumped the gun somewhat and is now forcing Acrobat users to use "file properties" metadata that is really only fully compatible with Adobe products. Is there a way I can get some backwards compatibility on this?
Thanks for any suggestions or insight anyone can provide to this vexing issue.
Phil.

Bridge has some pretty powerful and helpful features. However, I am unable to figure out how to access the non-XMP "file properties" fields through Bridge, and if I add metadata via Bridge, then I run into the same problem regarding the use of semi-colons to separate authors.
If I had more time, or a larger set of files I might investigate the use of ExtendScript to import all my metadata from an Excel file (where it already exists) into the PDF file properties and XMP metadata.
The best solution for my case though appears to be to use Acrobat 9 and to do the double-edit process for each file. I should be able to just cut-and-paste the metadata from the Excel file, and then if I save the Authors list to the end, I can simply paste it once into the XMP field (through the Advanced metadata button) and then return to the regular file properties page and paste it again in there, where Acrobat will add quotes around it.
Lastly, if anyone else happens to find this post and is looking for similar information, I would recommend searching in the Bridge forum as well as the Acrobat forum.
Phil.

Use PL/SQL procedure to guard against malformed CSV files before upload

Hi all,
In my CSV upload utility, I've implemented error checking procedures, but they are invoked only AFTER data has been uploaded to temp table. This doesn't catch the following sample scenarios:
1. The CSV is malformed, with some rows shifted due to fields and separators missing here and there.
2. User has chosen a wrong CSV to upload (most likely number of fields mismatch)
I'm wondering if it is a good idea to have procedure to read in the CSV, scan each line, count the number of fields (null fields but with delimiters showing the field exist is ok) for each record. If every single record matches the required number of fields for that table, then the CSV is ok, and the insert from external table to temp table is allow. This will ensure at least the CSV file has a valid matrix size for the target table, but rest of error checking is left until after temp table is populated.
One of my concerns is, I specify "missing field values are null" in the external table parameters, which is necessary since not all fields are required. Does this specification causes a row with missing trailing separators still considered valid? If so then the stored procedure must be programmed to omit such a case.
What do you think? Many thanks.

Hi, Cuauhtemoc Amox
Thank you for your advice. I have set web adi using PL SQL interface.
I have decided to go futher
i have a procedure like that
procedure delete_old_data ( p_id in number, p_description in varchar2)
as
begin
               begin
               if g_flag ='N' then
               delete from xx_test;
                g_flag='Y';
                else null;
                end if;
                end;
insert into xx_test (p_id,p_descriptiom);
end;
G_FLAG is a global variable with default value ='N' in my package. When web_adi upload
first row from excel sheet, then procedure delete all data from table and change g_flag to 'Y'.
All other rows uploads succesfully; it works fine.
But when user change data in excel sheet and try to upload second time. DELETE_OLD_DATA procedure doesnt work in proper way.
I have found what problem is. when user use same template and try to upload data several times there is same SESSION_ID in database.
i.e. g_flag ='Y' when user try to upload second time. But when user log off and create template again it is work properly.
My question is: How i can different upload attempts? May be there is some id for each upload proccess.
if i can use this ID in my procedure user will have opportunity to use same template.
Thank you

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.

How to upload files from a form using pl/sql ?

Hi
Is it possible to upload the physical files outside the database (under UNIX server)using pl/sql? I already know how to store the files inside the database(wwwdoc_documents$) but I didn't find any documentation about storing the physical files outside the database.
I have in my form the following component:
<input type="file" name="upload">
and I want to let the user browse for the file on his/her disc that he want to use. What I want to do next is to save a copy of that file on our file-server, and then use it in my application. How do I do that in pl/sql?
Any help will be appreciated.
Sebas.

Thanks for the suggestion. I like this approach as Java is more familiar to me than other languages.
Our DBA is out of touch today, so I could not grant the javauserpriv to my database user. I tried to run the script anyway in the chance that my user had the privs, and it seemed to have hung. I am now combing Oracle's site for more documentation so I can write some tests to see if I can get a basic Java object working. Under what heading would I find this?
