UNION ALL 导致缺少列

[wamdy]

当前使用版本(必填,否则不予处理)

1.4.7.2

该问题是如何引起的？(确定最新版也有问题再提!!!)

A->B UNION ALL A->B 导子后一个查询语句中缺少B表的字段

重现步骤(如果有就写完整)

MPJLambdaWrapper<SAD> wrapper;
    {
        wrapper = new MPJLambdaWrapper<>(SAD.class, "sad")
                .selectAll(SAD.class, "sad")
                .selectAssociation("ad", AD.class, SAD::getAD)
                .rightJoin(AD.class, "ad", AD::getSADId, SAD::getId);

    }

    MPJLambdaWrapper<SAD> wrapper1;
    {
        wrapper1 = new MPJLambdaWrapper<>(SAD.class, "sad")
                .selectAll(SAD.class, "sad")
                .selectAssociation("ad", AD.class, SAD::getAD)
                .leftJoin(AD.class, "ad", AD::getId, SAD::getADId);

    }
    wrapper1.unionAll(wrapper);

    this.selectJoinListPage(page, SAD.class, wrapper1);
