Spring 引导 "oracle.jdbc.OracleDatabaseException: ORA-00904: invalid identifier" 创建时出错 table

Question

在 spring 引导中，我使用代码优先方法创建数据库表。然后在运行应用程序时，其中一个表的结果显示此错误：

WARN  o.h.t.s.i.ExceptionHandlerLoggedImpl.handleException - GenerationTarget encountered exception accepting command : Error executing DDL "alter table statistic add date timestamp" via JDBC Statement
org.hibernate.tool.schema.spi.CommandAcceptanceExcepti
on: Error executing DDL "alter table statistic add date timestamp" via JDBC Statement]

oracle.jdbc.OracleDatabaseException: ORA-00904: : invalid identifier

class实体如下：

@Entity
@Table(name = "statistic")
public class Statistic {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    private String title;
    private Long value;
    private Date date;
    private String unit;


    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public Long getValue() {
        return value;
    }

    public void setValue(Long value) {
        this.value = value;
    }

    public Date getDate() {
        return date;
    }

    public void setDate(Date date) {
        this.date = date;
    }

    public String getUnit() {
        return unit;
    }

    public void setUnit(String unit) {
        this.unit = unit;
    }
}

有谁知道问题出在哪里？

Answer 1

这是错误的：

alter table statistic add date timestamp
                          ----
                          this

date 是 Oracle 数据类型 的保留字。将列名称更改为其他名称，例如datum、c_date、statistic_date、...然后是运行

alter table statistic add datum timestamp
