错误代码: 1005 Can't create table 'hibernate.bill' (errno: 150)

主要问题以及解决办法是：

1，MySQL支持外键约束，并提供与其它DB相同的功能，但表（外键表和外键主表）类型必须为 InnoDB，外键表和外键主表的类型都要是innoDB

建表约束语句:

user表:

CREATE TABLE `usert` (

`id` int(11) NOT NULL AUTO_INCREMENT,

`password` varchar(255) COLLATE utf8_unicode_ci DEFAULT NULL,

`userName` varchar(255) COLLATE utf8_unicode_ci DEFAULT NULL,

PRIMARY KEY (`id`)

) ENGINE=InnoDB

bill新表中有一个外键约束 tb_bill_fk指向 user表中的id :

CREATE TABLE bill (

id INT PRIMARY KEY NOT NULL AUTO_INCREMENT,

user_id INT,

CONSTRAINT FOREIGN KEY tb_bill_fk (user_id) REFERENCES usert(id)

) ENGINE=INNODB

MySQL外键创建条件: 1.两个表必须是InnoDB数据引擎2.外键表的外键字段必须是主键3.字段类型必须一致创建表时创建外键: create table tbl_client(userName varchar(255) not null, address varchar(255), createDate timestamp not null default now(), createUserName varchar(255), foreign key(createUserName) ref

mysql为表添加外键完成性约束报错Can't create table 'sfkbbs.#sql-513_25' (errno: 150)

代码 alter table sfk_son_module add constraint foreign key(father_module_id) references sfk_father_module(id) on delete restrict on update restrict; (constraint 后面可以加上约束名字) 错误原因是之前两张表的id的类型不一样,一个时int,一个时bigint 解决办法时修改表, alter table sfk_father_module mo

MySQL ERROR 1005: Can't create table (errno: 150)的错误解决办法

在mysql 中建立引用约束的时候会出现MySQL ERROR 1005: Can't create table (errno: 150)的错误信息结果是不能建立引用约束. 出现问题的大致情况 1.外键的引用类型不一样,主键是int外键是char 2.找不到主表中引用的列 3.主键和外键的字符编码不一致 4.还有要建立外键的话,要先建立索引.没有建立索引也会出错. MySQL ERROR 1005: Can't create table (errno: 150)的错误解决办法

Java---Hibernate>>Can't create table './xxx/#sql-b2c_1a.frm' (errno: xxx)解决方法

通用方案:删除相关表,重新生成. 1.关联表之间数据引擎不一致导致: 修改相关表的引擎设定,保持一致. 2.关联表索引字段的引用类型不一样(如A表关联字段是int,B表索引是char): 修改相关表的字段类型,保持一致. 3.主键和外键的字符编码不一致: 修改各自对应表编码格式,保持一致. 4.找不到主表中引用的字段或没有建立关联索引: 要么删索引,要么加字段. Java---Hibernate>>Can't create table './xxx/#sql-b2c_1a.frm' (errn
