Cannot create a file using UTL_FILE.FOPEN

Question

Dear All,
I am using this syntax for creating a file in window
i have declare this like this
l_file_id UTL_FILE.file_type;
l_file_name := 'DHL_'||110570284||'_'||TO_CHAR(SYSDATE,'ddmmyyyy')||'.txt'
l_file_id :=UTL_FILE.FOPEN('C:\D2R',l_file_name,'W');
Is this syntax work?
My database version is oralce 10g
Thanks

First of all, UTL_FILE is PL/SQL package and is executed on database server side, not on client side. Therefore, it is trying to create file in directory C:\D2R on database sefrver. So if you want to create file in directory C:\D2R on your client box - you can't. Next point - you are specifying directory explicitly which old and obsolete syntax. It requires, for security reasons to add C:\D2R to init.ora parameter UTL_FILE_DIR, otherwise UTL_FILE will raise an error. You should use directory objects:
CREATE DIRECTORY dir AS 'C:\D2R';and grant READ/WRITE on it to users. Then use:
l_file_id :=UTL_FILE.FOPEN('DIR',l_file_name,'W'); -- use directory name in upper caseAnd keep in mind, as I already mentioned UTL_FILE is PL/SQL package and is executed on database server side which means it runs under OS user oracle. Therefore OS user oracle must have write permission on C:\D2R.
