HI,

I have one Operating System text file in some directory in UNIX environment . How can I open this file inside one Stored Procedure.

Thanks in advance.

Hello,

to open flat files in the OS use the package SYS.UTL_FILE. You can use the functions/procedures fopen, get_line and fclose to access the datas in the ff.

You get direct access to the file you must enter the path of the file in your initial parameter. Otherwise Oracle can not read or write the file.

The parameter is UTL_FILE_DIR.

Here is a short example:

declare
fptr utl_file.file_type;
buff varchar2(2048);
line_no number(10):=0;
loc_no integer;
begin
fptr:=utl_file.fopen('C:\Oracle\admin\PENT\udump', 'ORA00324.TRC','R');
utl_file.get_line(fptr,buff);
utl_file.fclose(fptr);
exception
when no_data_found then
utl_file.fclose(fptr);
dbms_output.put_line('Number of lines parsed ='||line_no);
when utl_file.invalid_path then
dbms_output.put_line('invalid path');
raise_application_error(-20100,'file error');
when utl_file.invalid_mode then
dbms_output.put_line('invalid_mode');
raise_application_error(-20100,'file error');
when utl_file.invalid_filehandle then
dbms_output.put_line('invalid_filehandle');
raise_application_error(-20100,'file error');
when utl_file.invalid_operation then
dbms_output.put_line('invalid_operation');
raise_application_error(-20100,'file error');
when utl_file.read_error then
dbms_output.put_line('read_error');
raise_application_error(-20100,'file error');
when utl_file.write_error then
dbms_output.put_line('write_error');
raise_application_error(-20100,'file error');
when utl_file.internal_error then
dbms_output.put_line('internal_error');
raise_application_error(-20100,'file error');
when others then
dbms_output.put_line('un-handled');
raise_application_error(-20100,'file error');
end;

Hope that helps ?
