如何命名SQL FOREIGN KEY约束，将两个表列创建为关系表

Question

我只是想知道是否有一种方法可以在创建表上命名外键

FOREIGN KEY (uuid) REFERENCES employee(uuid));

我试图这样做，并将我的外键命名为fk1，但是语法错误

FOREIGN KEY fk1 (uuid) REFERENCES employee(uuid));

错误

org.springframework.transaction.CannotCreateTransactionException: Could not open JPA EntityManager for transaction; nested exception is com.jda.cloudsql.common.MigrationException: org.flywaydb.core.internal.dbsupport.FlywaySqlScriptException:

  FOREIGN KEY FK1[*] (UUID) REFERENCES EMPLOYEE(UUID)) "; expected "("; SQL statement:

Answer 1

你可以写：

ADD CONSTRAINT `customized_foreign_key_name` FOREIGN KEY (`uuid`) REFERENCES `employee` (`uuid`)
