Question

是否有可能在jasper中使用此记录获取此类布局以及如何执行此操作？

color_table

id | color_group | description
1  | primary     | the first
2  | secondary   | the second
3  | tertiary    | the third

color_table_details

color_table_id | color
1              | red
1              | blue
1              | yellow
2              | orange
2              | violet
2              | green
3              | etc

我想要的布局如下。

id       color group       description           color
1          primary           the first           red
                                                 blue
                                                 yellow
2          secondary         the second          orange
                                                 violet
                                                 green

Answer 1

我用以下解决方案解决了这个问题：

1. Added report group to the report
2. Added new variable with type of string (var_name)
3. On the variable expression property of the variable,
    $V{var_name} == null || ${var_name} == ""
    ? "1"
    : ${var_name} + ", 1"
4. Set the reset type of your variable to **Report** and its reset group to the report group you created at step 1
5. Then on your report layout, edit the text field expression of your id, color group and description to the following
    $V{var_name} == "1"
    ? ${field_name}
    : ""
