在oracle里运行这样一段小小的SQL也出错，急急急！

[ralphchen]

create table vc_collection_recordset(
userid varchar2(10) not null,
soundid varchar2(6) not null,
collectime date not null,
constraint FK1 foreign key (userid)
references user_basic(userid) on delete cascade，
constraint FK2 foreign key (soundid)
references voice_file(soundid) on delete cascade
);
运行后
ERROR 位于第 6 行:
ORA-00911: 无效字符
