Hi All
Nice to be in this Forum.
I have questions to ask on UTL_FILE :roll:
Let me explain the concept
1.When the net is down the user will take the records into on
floppy(CLIENT
2.When the net is up he will update the database(SERVER) with all th
trasaction including the records which he taken into the floppy

He creates one text file in the floppy. The records in that text fil
will be as follows

( '12-Dec-2004','
','1','111111111111','11',11111,11111,'',0,'Z','N' ,'M',
','N',11111,0,' ','12-Dec-2004',' ',0,' ',' ',' ',' ',0,'
','12-Dec-2004','

Question
********
1. Is it possible to pass floppy drive A: as parameter to UTL_FILE
2. If yes then do I need to create directory for this
3. If no then can I copy the file in floppy to other location fro
procedure
4. If yes then how can i do that
5. When I get the line from UTL_FILE handler Iam straight awa
inserting the line. Like for exampl
INSERT INTO CDYYMMDD1 VALUES(vNewLine)
Is is possible
6. How to go to the next line of UTL_FILE
7.How to open that file in a procedure

It will be very useful if you send in any sample code of same issue
Iam here with pasting you the procedure which I have implemented.Bu
it is not working due to the above mentioned Errors(Questions)

Utl_file runs on the Server not the client so the server can't see the A:
drive on the client. Why not have your client issue the commands to the
server as SQL inserts.

what is you client interface/tool?

what version of oracle?

as jim kennedy noted, utl_file is server side...

if you have a situation where client connectivity is a problem, is the issue
only related to writes (inserts)? or do you also have to make provisions for
reads?

in the simplest scenario, where you're just pushing data from the client and
need to buffer it locally if the network connection is down, why not just
save the SQL INSERT statements to a file (presumably on the hard disk, not
on the floppy drive) and then reissue them when the connection is up?
