JasperReports Server：使用输入参数在报表中进行多选查询

Question

请帮助我在我的报告中传递一个输入参数，以便我可以使用带有参数的多选查询。

在我的报告中，我使用的是$x{IN,ADMIN1,admins}，但得到了

错误：参数admins的java.lang.string类型错误，admins应该是一个数组或集合。

Mysql查询：

Select ADMIN1,WEEK1,WEEK2,WEEK3,(((WEEK3-WEEK2)/WEEK2)*100) as percentage_change, (WEEK3-

WEEK2) as MSU_Difference,SUMWEEK2,SUMWEEK3,SUMWEEK,WEEK4,WEEK5,(((WEEK5-WEEK4)/WEEK4)*100)

 as percentage_change_PRE,admin,ORGNo,OrgAbbr,msus from ((select admin as ADMIN1, sum(msu) 

as WEEK1 from sccp_raw where dt >= date_sub(date($P{start_date}), INTERVAL 14 DAY) and dt 

< date_sub(date($P{end_date}), INTERVAL 13 DAY) group by admin order by WEEK1) as 

q1,(select admin as ADMIN2, sum(msu) as WEEK2 from sccp_raw where dt >= 

date_sub(date($P{start_date}), INTERVAL 7 DAY) and dt < date_sub(date($P{end_date}), 

INTERVAL 6 DAY) group by admin order by WEEK2) as q2,(select admin as ADMIN3, sum(msu) as 

WEEK3 from sccp_raw where dt between $P{start_date} and $P{end_date} group by admin order 

by WEEK3) as q3,(select sum(msu) as SUMWEEK2 from sccp_raw where dt >= 

date_sub(date($P{start_date}), INTERVAL 7 DAY) and dt < date_sub(date($P{end_date}), 

INTERVAL 6 DAY))as q4,(select sum(msu) as SUMWEEK3 from sccp_raw where dt >= 

date_sub(date($P{start_date}), INTERVAL 14 DAY) and dt < date_sub(date($P{end_date}), 

INTERVAL 13 DAY))as q5,(select sum(msu) as SUMWEEK from sccp_raw where dt BETWEEN 

$P{start_date} and $P{end_date})as q6,(select sum(msu) as WEEK4 from sccp_raw where dt >= 

date_sub(date($P{start_date}), INTERVAL 372 DAY) and dt < date_sub(date($P{end_date}), 

INTERVAL 371 DAY)) as q7,(select sum(msu) as WEEK5 from sccp_raw where dt >= 

date_sub(date($P{start_date}), INTERVAL 365 DAY) and dt < date_sub(date($P{end_date}), 

INTERVAL 364 DAY)) as q8,(select sum(msu) as MSU from sccp_raw where dt between 

$P{start_date} and $P{end_date}) as q9,(select a.dt,a.admin,b.ORGNo, b.OrgAbbr, sum(a.msu) 

as msus from sccp_raw a left join (select ORGNo, ADMINS, OrgAbbr from orig) b on 

a.admin=b.ADMINS where a.dt between $P{start_date} and $P{end_date} group by a.admin)as 

q10)  where $X{IN,ADMIN1,admins} and ADMIN1=ADMIN3 and ADMIN2=ADMIN3 and admin=ADMIN3 

group by ADMIN1 order by WEEK3 desc; 

参数配置：

parameter "admins":  

class: `java.util.Collection`  

Default Value Expression: "select admin from sccp_raw group by admin"  

还帮助我了解是否要创建此下拉列表以选择为“所有管理员”，然后选择管理员列表。

对于Collection类型的multiselect参数，您不需要给出“All”来选择iReport中的所有值作为该参数的默认值，默认情况下表示所有值都被选中。

但如果参数是单选，那么查询 jasperreport 服务器输入控件将在输入控件值中获取“全部”：-

 SELECT * FROM (
 SELECT 'All Admins' admin from sccp_raw 
 UNION
 SELECT DISTINCT admin from sccp_raw) a
 ORDER BY admin

而 iReport 查询将是：-

  SELECT *
  FROM table
  WHERE ($P{admins}='All Admins' OR Admin=$P{admins}) 

例如，使用 ireport 中的示例 HSQL 数据库查看此报告：-

  <?xml version="1.0" encoding="UTF-8"?>
  <jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports"  
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<parameter name="p_SHIPCOUNTRY" class="java.lang.String">

            </jasperReport>

您必须在 jrxm 文件中使用 java.util.Collection。

Here, send your multi ids from your selection to your .jasper file.
      String qGelirGrubu = "1,2,3,4,5";
      String[] convertedGelirArray = qGelirGrubu.split(",");
      List<Integer> convertedGelirList = new ArrayList<Integer>();
      for (String number : convertedGelirArray) {
           convertedGelirList.add(Integer.parseInt(number.trim()));
      }
     parameters.put("qGelirGrubu1", convertedGelirList);

在您的 .jrxml 文件中； 像这样定义你的参数；

<parameter name="qGelirGrubu1" class="java.util.Collection"/>

您的 SQL 查询可以像这样使用您的参数；

select * from TABLE_NAME A where A.ID IN (1,2,3,4,5);像 .jrxml 文件中的那样：

 select * from TABLE_NAME A where  $X{IN,A.ID,qGelirGrubu1} 

$X{IN,COLUMN_NAME,YOUR_PARAMETER_NAME}
