Dear DBA Gurus,

Assume I have an emp table under Scott Schema with the following structure.

Name                                  Null?    Type
----------------------------------------- -------- -------------------------
---
EMPNO                           NOT NULL NUMBER(4)
ENAME                                            VARCHAR2(10)
JOB                                                VARCHAR2(9)
MGR                                                NUMBER(4)
HIREDATE                                           DATE
SAL                                                NUMBER(7,2)
COMM                                               NUMBER(7,2)
DEPTNO                                             NUMBER(2)

I need to calculate the size of the table assuming one of the rows is having all the columns maxsize possible. Say, 4+10+9+4+7+7+7+2=50. I need to do this for all the tables under a particular schema. How do I do this using Sql or Pl/Sql?

Any help in this regard will be very much appreciated.

TIA and Regards,

Ranganath
