Hello Expert
I really appreciate if some one help me out , I want to create flat file with .txt extension by using oracle table.
I'm wondering that I can achieve this task by using SQL Developer and few SQL Plus commands but the problem is that I want to create this flat file with some specified columns width.
For example : If I have scott.emp table then I want to create this flat file with the following width:
Empno 10
Ename 60
Job 30
I case if any column value is null then system don't care about it and assign the column specified width. for example if we have job column value is null then system still assign width 30. Can somebody help me out. Thanks in advance......

Actually, you will not need substr. RPAD takes care of truncation if the string is longer then the length specified.
test>select rpad('1234567890',5,' ') from dual;
