报表开发过程中，我们经常会需要根据所选择的不同指标，展示不同的报表！例如：
显示指标有：金额与合同数，可以根据显示指标选择的内容进行相应报表数据展示
一、环境准备

A.CONTRACT_NO,A.CONTRACT_AMT,A.START_DATE,A.END_DATE,A.REGISTER_DATE,B.* FROM contract_Info A INNER JOIN CRM_INFO B ON A.CRM_NO=B.CRM_NO 根据上述脚本建表后，可得到如下数据：
CRM_CONTRACT_RELATION
V_DIM_CRM_COUNTRY
将上述两个视图导入到资料库，然后关联，接着设计分析
二、仪表盘提示设计
使用变量VAR接受值，然后传值给分析，在分析中通过@{VAR}进行引用
三、分析设计
①国家：
"V_DIM_CRM_COUNTRY"."VALUE"
②vip金额：
ifnull(CASE WHEN '@{VAR}{金额}'='金额' AND "CRM_CONTRACT_RELATION"."CRM_TYPE"='vip' THEN "CRM_CONTRACT_RELATION"."合同金额" WHEN '@{VAR}'='合同数' AND "CRM_CONTRACT_RELATION"."CRM_TYPE"='vip' THEN "CRM_CONTRACT_RELATION"."CNT" ELSE NULL END,0)
③非vip金额：
ifnull(CASE WHEN '@{VAR}{金额}'='金额' AND "CRM_CONTRACT_RELATION"."CRM_TYPE"='uvip' THEN "CRM_CONTRACT_RELATION"."合同金额" WHEN '@{VAR}'='合同数' AND "CRM_CONTRACT_RELATION"."CRM_TYPE"='uvip' THEN "CRM_CONTRACT_RELATION"."CNT" ELSE NULL END,0)
④金额：
}{金额}'
四、仪表盘设计
将分析与仪表盘结合在一起，然后展示报表
五、展示报表
当选择【金额】时，
当选择【合同数】时
通过以上可以发现，我们的报表现在可以通过选择的【显示指标】不一致，显示不同的结果。
