我一直在嘗試使用MYSQL添加約束UNSIGNED到列。下面是我的桌子。在休眠INT(11)UNSIGNED約束
public class UserActivity implements BaseEntity{
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
Long id;
Long entityId;
@Column(columnDefinition = "enum('QUESTION','ANSWER', 'COMMENT', 'TAGS')")
@Enumerated(EnumType.STRING)
Type type;
@ManyToOne
@JoinColumn(nullable = false, columnDefinition="INT(11) UNSIGNED")
CustomerEntity user;
但它不創造因的外鍵和索引沒有建立數據庫約束用戶列。 This和this忍不住。請幫助我。感謝
原木:
Hibernate:
alter table UserActivity
add constraint FK_jfw954ii6gw7mbqdth6y3n0rs
foreign key (user_Id)
references customerDb.customer (Id)
12:31:30.350 [localhost-startStop-1] ERROR o.h.tool.hbm2ddl.SchemaExport - HHH000389: Unsuccessful: alter table UserActivity add constraint FK_jfw954ii6gw7mbqdth6y3n0rs foreign key (user_Id) references customerDb.customer (Id)
12:31:30.350 [localhost-startStop-1] ERROR o.h.tool.hbm2ddl.SchemaExport - Can't create table 'community_db.#sql-43f0_5a07' (errno: 150)
Hibernate:
MySQL的查詢:
ALTER TABLE `community_db`.`Question`
ADD INDEX `fk_Question_Customer_idx` (`author_Id` ASC);
ALTER TABLE `community_db`.`Question`
ADD CONSTRAINT `fk_Answer_Customer`
FOREIGN KEY (`author_Id`)
REFERENCES `customerDb`.`customer` (`Id`)
ON DELETE NO ACTION
ON UPDATE NO ACTION;
和下面是上述MySQL的查詢日誌:
Error Code: 1005. Can't create table 'community_db.#sql-43f0_5d19' (errno: 150) 0.048 sec
你能發佈你得到的實際錯誤嗎? –
在我搜索'UNSIGNED'的日誌中找不到。沒有查詢UNSIGNED和show_sql和format_sql爲真 –
@TimBiegeleisen我已經添加了來自日誌的查詢 –
