레퍼런스를 보믄..다음과 같이 나오는구먼유~
LONG columns cannot appear in certain parts of SQL statements:
1. WHERE clauses, GROUP BY clauses, ORDER BY clauses, or CONNECT BY clauses or with the DISTINCT operator in SELECT statements
2. The UNIQUE operator of a SELECT statement
3. The column list of a CREATE CLUSTER statement
4. The CLUSTER clause of a CREATE MATERIALIZED VIEW statement
5. SQL functions (such as SUBSTR or INSTR)
6. Expressions or conditions
7. SELECT lists of queries containing GROUP BY clauses
8. SELECT lists of subqueries or queries combined by set operators
9. SELECT lists of CREATE TABLE ... AS SELECT statements
10. SELECT lists in subqueries in INSERT statements
말씀하신 것은 9번에 해당하는군요~
그려서..에러가 나는 것 같은디용~

:: 제가 질문한건요.... long을 서브쿼리로 질의 하는것이 아니라
:: SQL> create table ccc (

::
:: 이 경우에
:: 서브쿼리를 이용하여 또 하나의 테이블 생성시를 이야기 하는 것입니다.
:: SQL> CREATE TABLE ddd
