jasper 表中单列内的多行

Question

我只是贾斯珀报告的初学者，我在一个问题上被困了几天。我有两张桌子

药物{ID,medication_name}和剂量_时间{ID,medication_id,dose_time}

正在申请

SELECT m.id,m.medication_name,d_t.dose_time FROM medication `m`
LEFT JOIN dose_time d_t ON m.id=d_t.medication_id;

给了我三个结果

现在我想要的是跟随贾斯珀报告

但我可能会卡住并且只能生成以下 jasper 格式

我的jrxml文件如下

您可以为此使用交叉表。转到窗口并单击调色板。比调色板会显示正确。最后，将“交叉表”拖到摘要部分并填写向导。
