Spring Data JPA Query: Prepopulate/update one table based on total amount of true/false values from another table

问题

I have an issue with populating a table based on the results from another table. Table 1 collects submission data for a user on a given project. The submission data collected consists of tasks that the user carried out on the project and is stored in the table as a boolean value (true if they carried out the task and false if they haven't). The table values can be found in the Entity class below:

此处涉及问题:将一个表格根据另一个表格的结果进行填充。表格1收集用户在给定项目上的提交数据。收集的提交数据包括用户在项目上执行的任务,并以布尔值的形式存储在表格中(如果他们执行了任务则为true,否则为false)。表格的值可以在以下的Entity类中找到:

@Entity
@Table(name = "trackersubmission")
public class TrackerSubmit {
    // ... (其他属性和构造函数)
}

Additionally, Table 2 is an overview of the first which should collect the total number of each task carried out by each user over all the projects they have carried out. This can be seen below:

此外,表格2是表格1的概述,应该汇总每个用户在他们进行的所有项目中执行的每个任务的总数。如下所示:

@Entity
@Table(name = "prooverview")
public class ProjectPerformance {
    // ... (其他属性和构造函数)
}

I have created the following Query statement in an attempt to update Table 2 based on submissions in Table 1.

我已经创建了以下的查询语句,试图根据表格1中的提交来更新表格2。

@Query("UPDATE ProjectPerformance p INNER JOIN "
        + "(SELECT user_id, osra, wsra, quoting, scoping, idcopier, componentchecker, nodetool, review, leadrole, parc, onsite, statuscheck FROM TrackerSubmit GROUP BY user_id WHERE statuscheck = TRUE ) x"
        + "ON p.user_id = x.user_id"
        + "SET p.osra = COUNT(x.osra = TRUE), p.wsra = COUNT(x.wsra = TRUE). p.quoting = COUNT(x.quoting = TRUE), p.scoping = COUNT(x.scoping = TRUE), p.idcopier = COUNT(x.idcopier = TRUE, ), p.componentchecker = COUNT(x.componentchecker = TRUE), p.nodetool = COUNT(x.nodetool = TRUE), p.review = COUNT(x.review = TRUE), p.leadrole = COUNT(x.leadrole = TRUE), p.parc = COUNT(x.parc = TRUE), p.onsite = COUNT(x.onsite = TRUE)")

However, when I attempt to run this query I am flagged with the SQL error:

然而,当我尝试运行此查询时,我收到SQL错误:

2020-07-31 10:22:15.456 ERROR 2452 --- [ main] o.h.hql.internal.ast.ErrorTracker : line 1:22: expecting "set", found 'INNER'
2020-07-31 10:22:15.458 ERROR 2452 --- [ main] o.h.hql.internal.ast.ErrorTracker : line 1:22: expecting "set", found 'INNER'

antlr.MismatchedTokenException: expecting "set", found 'INNER'

Any help is much appreciated!

希望能提供帮助!

Appears to be an issue with your query.

Few imp points

  1. Update needs to be followed by SET
  2. Update can be done on one table at a time. So if you want to make an update, the query will be line

update table set field = (select column from table a join table b on condition where condition`) or something similar.
