我目前正在尝试从Hibernate生成我的ddl方案切换到Flyway迁移。我通过这种方式生成了我的V1__Initial. sql脚本。当我在内存H2数据库上运行它时,一切正常。但是当我尝试在MariaDB上运行它时,我得到了以下异常:

Migration V1__Initial.sql failed
--------------------------------
SQL State  : HY000
Error Code : 1005
Message    : (conn=130) Can't create table `booking`.`booking_cancelled_event` (errno: 150 "Foreign key constraint is incorrectly formed")
Location   : db/migration/V1__Initial.sql (C:\code\ajt\backend\target\classes\db\migration\V1__Initial.sql)
Line       : 463
Statement  : alter table booking_cancelled_event
   add constraint FKnxiyj0m730pl9ol2y4qng7577
   foreign key (cancelled_booking_id)
   references cancelled_internal_booking

V1__Initial.sql中的相应部分:

alter table booking_cancelled_event
   add constraint FKnxiyj0m730pl9ol2y4qng7577
   foreign key (cancelled_booking_id)
   references cancelled_internal_booking;

SHOW ENGINE InnoDB STATUS的输出;:

------------------------
LATEST FOREIGN KEY ERROR

2019-06-23 21:07:30 0x1974 Error in foreign key constraint of table `xxx`.`booking_cancelled_event`:

根据MariaDB文档的ALTER TABLE页面,< code>ADD CONSTRAINT的语法应该是:

ADD [CONSTRAINT [symbol]]
    FOREIGN KEY [IF NOT EXISTS] [index_name] (index_col_name,...)
    reference_definition

根据 MariaDB 文档的 CREATE TABLE 页面,reference_definition的语法应该是:

REFERENCES tbl_name (index_col_name,...)
  [MATCH FULL | MATCH PARTIAL | MATCH SIMPLE]
  [ON DELETE reference_option]
  [ON UPDATE reference_option]

所以您遇到的解析错误很可能是因为您遗漏了一个< code>(index_col_name,...)在< code > cancelled _ internal _ booking 表名之后。
