如图：程序员在进行如下的统计时，现在提供两种实现方案：
方案一：运用 SEKECT CASE WHEN
EXPLAINSELECT count(*) AS "总数", count( CASE oup.status WHEN "1" THEN oup.id END ) AS "未绑定", count( CASE oup.status WHEN "2" THEN oup.id END ) AS "已绑定", count( CASE oup.status WHEN "3" THEN oup.id END )AS "冻结中"FROM lab_org_uc_passport oup
显示结果：(按行显示)
方案二：
SELECT count(*) AS "总数" FROM lab_org_uc_passport oup UNION ALLSELECT count(*) AS "未绑定" FROM lab_org_uc_passport oup WHERE oup.status = "1"UNION ALLSELECT count(*) AS "未绑定" FROM lab_org_uc_passport oup WHERE oup.status = "2"UNION ALLSELECT count(*) AS "未绑定" FROM lab_org_uc_passport oup WHERE oup.status = "3"
显示结果(按列显示)
