[Oracle-l] help with batch operation

The file name can change, but you have to use DDL to do so:

ALTER TABLE table_name LOCATION ( 'new_file_name.csv' );

I found that out the hard way...at least it was in dev. I did
something like this previously for a DW environment.

Part I <http://www.oraclenerd.com/2008/04/validating-process.html> and
Part II <http://www.oraclenerd.com/2008/05/validating-process-part-ii.html>

Essentially what you need to do, is create a simple java class that
can read the contents of your directory,
wrap that up in a PL/SQL Stored procedure then loop through the
directory contents.

I think your best option, to avoid DDL, is to rename the file in the
directory using a combination of Java (directory contents)
and UTL_FILE to rename the file to some "common" name you choose. You
can utilize the same methodology to move
the files after you have completed processing.

Hope this helps.

Hi all,

Thanks Chet,
I actually like the first approach, where I can alter table location.
So, is this how it would be done?
Procedure alter_table_p (vNew_loc in varchar2)
Is
Begin

Execute immediate 'alter table ORIG_TABLE location (:x)' using vNew_loc;

End;

Hi all,

Running Oracle 9.2 on Windows.

I know this is Oracle forum, but it's somewhat related. This question is for those of you who run Oracle on Windows.

I have several ".txt" files in a directory (all different names) and looking for the possibility to do the following using .BAT file:

Take first file

rename it

run procedure (pass it in)

move it into archive dir

delete it from original dir

GOTO 1

Reason I have to do all this is because in step 3 I am using external table to read the ".txt" file and it has to have a unique file name.

That is correct, assuming that vNew_loc is just a file name. The LOCATION
keyword threw me off initially as the location was not changing, just the
file name.

In the first option I forgot to write the sqlplus command between the
copy and the move.

Thanks for your reply, I, however went with "alter table...." option. Easier and cleaner in my opinion.

I read the replies and I assume that all the files are in the same structure as you are reading them using the same external table.
You have several options:
1) If you can process the data from all the files in the same time AND have disk space

you can use:
copy a.txt+b.txt+c.txt target.txt
move *.txt archive\*.old /Y -->move the files and rename them to old, overwrite existing files in archive.
this will give you one big file, target.txt, that is concatenation of all the files and you can process that.
2) Use the for command.

for %i in (*.txt) do call process_file %1
and create file call_process.cmd that do:
copy %1 target.txt --> I prefer copy as the original file remains a is in case of problems, you can use rename.
sqlplus whatever
move %1 archive\%1 /Y --> move the file to archive directory and overwrite old file with that name
exit
