oracle报无效sql语句,ORA-00900：无效的SQL语句Oracle错误

我是oracle新手。我正在尝试使用HPDMA工具运行oracle脚本，后者又调用创建表模式的表创建脚本。我得到的脚本之一以下错误：ORA-00900：无效的SQL语句Oracle错误

Table MODEL

declare

*

ERROR at line 1:

ORA-00900: invalid SQL statement

ORA-06512: at line 46

下面是创建表的脚本：46

SET DEFINE OFF;

Prompt Table MODEL;

declare

l_count int;

begin

select count(*)

into l_count

from all_tables

where owner = 'PORTAL'

and table_name = 'MODEL';

if l_count = 0 then

execute immediate

'CREATE TABLE PORTAL.MODEL

end if;

end;

线具有NOCACHE声明。我在其他数据库上运行脚本时没有发生此错误。

任何帮助，将不胜感激。谢谢。
