Answer 1

You are creating this table with an execute immediate statement. Which suggests that it doesn't exist yet. Therefore your insert statement is referencing a non-existent table so naturally it won't compile.
If you really want to do this you should put the insert into an execute immediate statement as well. However, I recommend that you don't do this - it is very bad practice to put this sort of processing in the exception handler. Why? Well, what happens if the table T_CALLING already exists? The exception's got no where to go, so your program fails with an Unhandled Exception error.
