   "MT_ID" NUMBER(10,0),
   "MT_CODE" VARCHAR2(50 BYTE) not null,  
     "MT_DESC" VARCHAR2(600 BYTE) not null,  
     "MT_5497_CODE" NVARCHAR2(50) not null,

     CONSTRAINT TB_MTBasicInfo PRIMARY KEY

原来命令行里建表如果是带引号的，那么在使用的时候也要带引号，如果命令如下：

desc “DBDATAFILESPACE”.“TB_MTBasicInfo”

就不会有任何问题了。

带引号的时候，大小写是敏感的
