將多個 @params 傳遞給 JPA 中的存儲過程

Question

@Query(value = "DECLARE @StartDateTime DATETIME = DATEADD(hour,-1,GETUTCDATE()) EXEC [Fetch].[mevisio_downtimedata] " +
            "@StartDateTime = :startDateTime," +
            "@workCenterList = :workCenterList",nativeQuery = true)
    List<DownTimeData> retriveOneHrDowntime(@Param("startDateTime") LocalDateTime startDateTime, @Param("workCenterList") List<String> workCenterList);

得到錯誤：

Answer 1

您不能使用@Query執行存儲過程

您必須在實體上定義NamedStoredProcedureQuery

@Entity
@NamedStoredProcedureQuery(name = "User.plus1", procedureName = "plus1inout", parameters = {
  @StoredProcedureParameter(mode = ParameterMode.IN, name = "arg", type = Integer.class),
  @StoredProcedureParameter(mode = ParameterMode.OUT, name = "res", type = Integer.class) })
public class User {}

然后你可以使用@Procedure來執行它

@Procedure
Integer plus1inout(@Param("arg") Integer arg);
