如何命名SQL FOREIGN KEY约束，将两个表列创建为关系表

i was just wondering if there is a way to name a foreign key on create table

i tried to do this and name my foreign key as fk1 but i've got syntax errors

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

error

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:

你可以写：

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