oracle.jdbc.OracleDatabaseException：ORA-00932：不一致   数据类型：预期DATE得到NUMBER

我最终想要的查询，我猜只是使用spring CrudRepository格式不正确：

select * from user_usage where Prs_Id=1104438622 and createddate > sysdate -1;

desc user_usage

Name          Null     Type           
------------- -------- -------------- 
USAGETYPEID   NOT NULL NUMBER(3)      
PRS_ID        NOT NULL NUMBER(18)     
CREATEDID     NOT NULL NUMBER(10)     
CREATEDDATE   NOT NULL DATE           
COMMENTS               VARCHAR2(4000) 
USERAGENTID            NUMBER(10)

1）POJO

    @Entity
    @Table(name="USER_USAGE)
    public class Usage {

        @Column(name="Prs_Id")
        @Id
        private long prsId;

        @Column(name="createddate")
        private Date createddate;

2）存储库

    public interface UsageRepository extends CrudRepository<Usage, Date>{


        //select * from user_usage where Prs_Id=1104438622 and createddate > sysdate -1; --query that I want eventually 
         @Query("SELECT a FROM Usage a WHERE a.prsId=:prsId and a.createddate>=:createddate-1")
         Usage fetchUsageGreaterThanEqual(@Param("prsId") Long prsId, @Param("createddate") Date createddate);
    }

3）控制器：

    @Autowired
    UsageRepository usageRepository; 
    static Date myDate;

    @GetMapping("/{prsId}")
     public Usage getUsageByPrsId(@PathVariable Long prsId) {
      return usageRepository.fetchUsageGreaterThanEqual(prsId, myDate);
     }

Answer 1

您的Date类很可能是java.util.Date

static Date myDate;

您必须按照here所述将其转换为java.sql.Date

new java.sql.Date(createddate.getTime())

避免出现ORA-00932: inconsistent datatypes: expected DATE got NUMBER

问题

或者，您也可以使用java.time和here

讨论的there类
