Table Structure copy

Question

Question 1) If i take table structure through script to create new table with the same structure, will i get indexes also which were created on columns?

 

Question 2) If i took full back today and deferential back up tommarow, while restoring which one i need to restore first full or deferential?

 

Question 3) table 1 had 3 rows and table 2 had 3 rows.

                  then   select * from table1,table2 why 9 rows will come, why not 6?
