where IN 子句 - 多列（querydsl）

Question

我有两对的三个整数值。
我想将其用作 WHERE 子句中的 IN 列表。

(2019, 5) (2019, 6) (2019, 7)

我想在这样的查询中使用上面的两对列表：

SELECT
    *
FROM
    WEEK_REPORT A
WHERE
    A.user_id IN ('test2','test5' ) AND
    (A.year, A.week_no) IN ((2019,4),(2019,5),(2019,6));

为此，我写了如下源代码：

// lastYear=2019, lastWeekNo=4
Tuple t = JPAExpressions.select(Expressions.constant(lastYear), Expressions.constant(lastWeekNo))
    .from(weekReport)
    .fetchOne();

// currentYear=2019, currentWeekNo=5        
Tuple t2 = JPAExpressions.select(Expressions.constant(currentYear), Expressions.constant(currentWeekNo))
    .from(weekReport)
    .fetchOne();

// nextYear=2019, nextWeekNo=4
Tuple t3 = JPAExpressions.select(Expressions.constant(nextYear), Expressions.constant(nextWeekNo))
    .from(weekReport)
    .fetchOne();

return queryFactory
    .select(weekReport)
    .from(weekReport)
    .where(weekReport.user.eq(user)
        .and(Expressions.list(weekReport.year, weekReport.weekNo).in(t, t2, t3)))
    .fetch();

但是，不会输出正确的结果并发生错误。

java.lang.UnsupportedOperationException: null
    at com.querydsl.jpa.JPASubQuery.fetchOne(JPASubQuery.java:66) ~[querydsl-jpa-4.1.4.jar:na]

我在官方文档里查了一下，没有出来。
有办法吗？

谢谢你。

尝试这个

SELECT
    *
FROM
    WEEK_REPORT A
WHERE
    A.user_id IN ('test2','test5' ) AND
    concat(A.year, A.week_no) IN (20194,20195,20196);
