SQL查询：

CREATE TABLE  `Acc_inst` (

 `inst_ID` INTEGER NOT NULL AUTO_INCREMENT,`inst_Name` VARCHAR( 255 ),`Inst_Ws` VARCHAR( 255 ),`inst_ph` VARCHAR( 255 ),`inst_Fx` VARCHAR( 255 ),`Inst_E` VARCHAR( 255 )
) ENGINE = INNODB DEFAULT CHARSET = utf8;

1075 – Incorrect table definition; there can be only one auto column and it must be defined as a key

事实上只有自动增量列,它被定义为主键,所以我不明白为什么它给我这个错误
