1. For complex tasks it is usually preferable to create a package with a variety of procedures, so that your solution is modularized. Additional benefit is use of package variables to retain state.
2. Create the following function:
FUNCTION file_present (p_location IN VARCHAR2, p_file IN VARCHAR2) RETURN BOOLEAN IS
BEGIN
v_fp := UTL_FILE.FOPEN(p_location,
UTL_FILE.FCLOSE(v_fp);
RETURN TRUE;
EXCEPTION
WHEN OTHERS THEN
RETURN FALSE;
END file_present;
In your code:
IF file_present('X:\','myfile
--execute the procedure;
END IF;
Note that 'location' must be an accessible directory, as defined in the instance’s initialization parameter UTL_FILE_DIR.
