我有一个用数据库编写的过程。 my_procedure(val1,val2)
所以,可以说我有一个这样的数据库查询:
MM_TO_UNITS
我想将其转换为Spring的Data JPA @Query。像这样:
select field1 as fieldName, field2 as fieldId
(select * from mydb.my_procedure(id)) as aValue // A procedure call
from mydb.my_table
我们允许这样做吗?
更新
例如,我有以下要转换的查询。
@Query (" HERE I WANT THE ABOVE QUERY TO IMPLEMENT")
public List<MyTable> getDetails ()
我想做类似的事情
select id, name, roll,
(select * from db.calculate_fee (date, id)) fee
from Student
where id = 1 AND roll = 5
反正有这样做吗?

您是否尝试过使用本机查询?
@Query(nativeQuery = true, value = "select field1 as fieldName, field2 as fieldId...")
List<MyTable> getDetails();
(顺便说一句,由于存储库是接口,'getDetails'不需要public)

@NamedStoredProcedureQueries({
@NamedStoredProcedureQuery(name = "getAllEmployees",
procedureName = "get_all_employees",
resultClasses = Employees.class)
})
@Procedure(name = "getAllEmployees")
List<Employees> getAllEmployees();
