不能在MySQL数据库中创建表

Question

我想在MySQL数据库中创建表的SQL以下

CREATE TABLE IF NOT EXISTS `dev_dict`.`TAMILWORD_SECONDARY` (
    `ID` INT NOT NULL , 
    `TAMILWORD_ID` INT NOT NULL , 
    `WORDS` VARCHAR(50) NOT NULL , 
    `CREATED_DTTM` TIMESTAMP NOT NULL , 
    `MODIFIED_DTTM` TIMESTAMP NOT NULL , 
    PRIMARY KEY (`ID`) , 
     UNIQUE INDEX `WORDS_UNIQUE` (`WORDS` ASC, `TAMILWORD_ID` ASC) , 
     INDEX `FK_TAMILWORD_ID_idx` (`TAMILWORD_ID` ASC) , 
    CONSTRAINT `FK_TAMILWORD_ID` 
     FOREIGN KEY (`TAMILWORD_ID`) 
     REFERENCES `dev_dict`.`TAMILWORD` (`ID`) 
     ON DELETE NO ACTION 
    ON UPDATE NO ACTION) 
    ENGINE = InnoDB 

，但得到错误代码：1022。无法写入;表'tamilword_secondary'中的重复键。

感谢帮助我..我有表tamilword已经，并获得同样的错误

CREATE TABLE IF NOT EXISTS `dev_dict`.`TAMILWORD` (
    `ID` INT NOT NULL , 
    `WORD` VARCHAR(50) CHARACTER SET 'utf8' COLLATE 'utf8_general_ci' NOT NULL , 
    `SENTENCE` VARCHAR(100) NULL , 
    `CREATED_DTTM` TIMESTAMP NOT NULL , 
    `MODIFIED_DTTM` TIMESTAMP NOT NULL , 
    PRIMARY KEY (`ID`) , 
     INDEX `SECONDARY` (`WORD` ASC, `SENTENCE` ASC)) 
    ENGINE = InnoDB 

Answer 1

首先创建dev_dict.TAMILWORD表。 除此之外，你的陈述的作品。
