自定義SQL查詢，可將SELECT結果插入Spring Boot JPA Hibernate中的表中

Question

我有一個使用JPA休眠的Spring Boot項目。

我試圖做一個自定義查詢，將select的結果插入到表中。 我該怎么做？

這是我的SQL查詢：

INSERT INTO aggregateTable

  (
    SELECT
      avgSalesA,
      avgSalesB,
      salesMade,
      tableA.employeeid
    FROM

      (
        SELECT
          avg(sales) as avgSalesA,
          count(salesMadeDaily) as SalesMadeTotal,
          employeeid
        FROM companyA
        GROUP BY employeeid
      ) tableA

    INNER JOIN

    (
      SELECT
        avg(sales) as avgSalesB,
        employeeid
      FROM companyB
      GROUP BY employeeid
    ) tableB

    ON tableA.employeeid = tableB.employeeid
  )

Answer 1

您可以簡單地使用JPA：

entityManager.executeUpdate("INSERT INTO aggregateTable (Select avgSalesA, avgSalesB, 
                             salesMade, tableA.employeeid FROM 
                             (SELECT avg(sales) as avgSalesA, count(salesMadeDaily) as 
                             SalesMadeTotal, employeeid FROM companyA GROUP BY 
                             employeeid) tableA INNER JOIN (SELECT 
                             avg(sales) as avgSalesB, employeeid FROM companyB group 
                             by employeeid) 
                             tableB ON tableA.employeeid = tableB.employeeid)");

或者如果您使用Spring Data倉庫

@Modifying
@Query("<your insert query", nativeQuery=true)
public int insert();
