英文:
@OneToOne Uni directional with cascading didn’t delete by sql query
问题
<br>
我尝试创建两个表（主表和辅助表）<br>并使用@OneOnOne关系。（我正在使用Postgres）<br>
我像这样定义了主表：
Class Table1{
@GeneratedValue
@Id
@Column
private int Id;
@OneToOne(cascade =CasscadeType.ALL)
public Table2 table2;
我的问题是，当我尝试通过SQL查询删除表（从Table1中删除）时，数据从Table1中删除，但它没有从与Table1相关联的table2中删除行。

@OneToOne(cascade =CasscadeType.ALL)

你可以尝试这样做：
@OneToMany(cascade=CascadeType.ALL)
英文:
You should try this:
@OneToMany(cascade=CascadeType.ALL)
