Standard says (4.41 SQL-transactions):
It is implementation-defined whether or not the non-dynamic or dynamic execution of an SQL-data
statementor the execution of ^^^^^^^^^^^^^^^^^^ an <SQL dynamic data statement>
ispermitted to occur within the ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ same
SQL-transactionas the non-dynamic or dynamic execution of ^^^^^^^^^^^^^^^^^^^^^^^ an SQL-schema
statement.If it does occur, then the effect on any ^^^^^^^^^^^^^^^^^^^^^^^
So, you see that this idea came not to Oracle only...
I don't object against DDLs inside BEGIN/END.
I just mean that it's not required by standard.
If someone is ready to fix this area - welcome.
