Fixed lenght or offset for columns

length like eg : empnum should be in 1 to 5 lenght and empnum from 6 to 25country if there is no data
space should resereved from 26 to 40 and so on.If the field is blank the space should be preserved i tried
lpad,ltrim,nvl but its not working

Answer 1

I hv the following sample of the EMP table :
EID     ENAME     EJOB     ESAL     EDEPT     COMM
1234     BUNNY     ROCKSTAR     23000     20     
1235     YORK          60000     30     15000
2222     ABC     TEACHER     45000     30     
2345     ROCKY     TRAINEE     15000     20     19000
3456     MADDY     BOXER     45000     10     45000
4567     WITTY     STUDENT     12000     30     12000This is the query I used with RPAD, I used "*" as a filler for better readability.
select rpad(e.eid,6,'*')||rpad(e.ename,30,'*')|| rpad(nvl(ejob,'---------'),20, '*')||rpad(e.esal,7,'*')||rpad(e.edept,4,'*')||rpad(nvl(e.comm,0),7,'*') rpad
from emp e;The output is as follows :
1234**BUNNY*************************ROCKSTAR************23000**20**0******
1235**YORK**************************---------***********60000**30**15000**
