關于create table命令上的重復鍵，我收到1022錯誤。看完查詢后，我不知道在哪里進行復制。有人可以看到嗎？

SQL query:

-- -----------------------------------------------------

-- Table `apptwo`.`usercircle`

-- -----------------------------------------------------

CREATE TABLE IF NOT EXISTS? `apptwo`.`usercircle` (

`idUserCircle` MEDIUMINT NOT NULL ,

`userId` MEDIUMINT NULL ,

`circleId` MEDIUMINT NULL ,

`authUser` BINARY NULL ,

`authOwner` BINARY NULL ,

`startDate` DATETIME NULL ,

`endDate` DATETIME NULL ,

PRIMARY KEY (? `idUserCircle` ) ,

INDEX? `iduser_idx` (? `userId` ASC ) ,

INDEX? `idcategory_idx` (? `circleId` ASC ) ,

CONSTRAINT? `iduser` FOREIGN KEY (? `userId` ) REFERENCES? `apptwo`.`user` (

`idUser`

) ON DELETE NO ACTION ON UPDATE NO ACTION ,

CONSTRAINT? `idcategory` FOREIGN KEY (? `circleId` ) REFERENCES? `apptwo`.`circle` (

`idCircle`

) ON DELETE NO ACTION ON UPDATE NO ACTION

) ENGINE = INNODB;

MySQL said: Documentation

#1022 - Can't write; duplicate key in table 'usercircle'
