oracle - Create a Sequence with START WITH from Query

Question

How can I create a Sequence where my START WITH value comes from a query?

I'm trying this way: CREATE SEQUENCE "Seq" INCREMENT BY 1 START WITH (SELECT MAX("ID") FROM "Table");

But, I get the ORA-01722 error

The START WITH CLAUSE accepts an integer. You can form the "Create sequence " statement dynamically and then execute it using execute immediate to achieve this.

declare
    l_new_seq INTEGER;
begin
   select max(id) + 1
   into   l_new_seq
   from   test_table;

    execute immediate 'Create sequence test_seq_2
                       start with ' || l_new_seq ||
                       ' increment by 1';
end;
