Can we have same execution plan for a create table statement where the name of the table changes every time as follows:
create table test
as
select * from t1
Here table name changes from test to another table name next time

say,
explain plan for
create table test1
as
select * from abc
after creating table test1 if I execute the following
explain plan for
create table test5
as
select * from test1
The explain plan doesn't use the earlier explain plan but I need it.Can we do?

Explain plans and execution plans are specific to queries.
You are running two different queries (it might be getting the same data but it is getting it from a different place).
Why would you expect them to be the same?
What are you trying to achieve?
