UTL_fILE

Hai,

I have a text file which contains rows upto 1M.
Instead of using SQLLOADER I want to use UTL_FILE concept to insert those records into the
different oracle tables.

Can any one have an idea ,If have please provide an example..

Thanks for the Advance in Help..

Re: UTL_fILE

Hi,

I have never done any file reading using UTL_FILE, although I have used to write out to files. As Oracle features go, it is pretty poor: it has poor error handling, and is pretty slow - especially compared to SQL-LOADER.

Good Luck

Steve
If at first you do not succeed. Destroy all evidence that you even attempted.

Hi

check the enclosed note from Oracle Metalink. Here you'll find how to set up a function to read and write from/to files:

To read from files, check the following section of the note:
-- Open the same file to read from
file_handle :=
UTL_FILE.FOPEN('/tmp','myfile.txt','R');

-- Read a line from the file.
UTL_FILE.GET_LINE (file_handle, retrieved_buffer);

-- Print fetched line out to the SQL*PLUS prompt.
DBMS_OUTPUT.PUT_LINE(retrieved_buffer);

-- CLose the file.
UTL_FILE.FCLOSE(file_handle);

Re: UTL_fILE

SQL*Loader, specially using direct path, loads fast but within sqlloader, you cannot add logic such as "if the row exists then update else insert".
If this is what you need to do, then you will use the UTL_FILE package.

Re: UTL_fILE

Hi there.
Go for the sqlloader.
Faster, easier to handle.
If you read the manual, check for ctl files
( param files for sqlloader ).
There you can set conditions for the load.
