我正在尝试从表中删除或选择数据，因为我使用的是Spring数据JPA。
我面临的例外是“javax.persistence.PersistenceException: org.hibernate.exception.GenericJDBCException: could not execute query”

实体类如下所述
@Entity
@Table(name = "EMPLOYEE")
public class Employee {
@Id
@Column(name = "ID")
private Long id;
@Column(name = "EMPLOYEE_ID")
private Long employeeId;
@Column(name = "EMPLOYEE_TYPE")
private String employeeType;
public void setId(Long id) {
this.id = id;
}
public void setEmployeeId(Long employeeId) {
this.employeeId = employeeId;
}
public void setEmployeeType(String employeeType) {
this.employeeType = employeeType;
}
}
存储库类是
public interface EmployeeRepository extends JpaRepository<EMPLOYEE, Long> {
}
执行以下查询
EmployeeRepository empRepo;
empRepo.deleteAll();
CREATE TABLE DB.EMPLOYEE
(
ID NUMBER(19) NOT NULL,
EMPLOYEE_ID VARCHAR2(255 CHAR),
EMPLOYEE_TYPE VARCHAR2(255 CHAR)
)
请建议。
答案 0 :(得分：0)
感谢Maciej发布的帖子已被删除我不知道怎么样:)我已经在你的建议的帮助下解决了这个问题，我在做错了 如果与表设计进行比较，EMPLOYEE_ID的数据类型在实体类中是不同的。
