partyname state constituency candidatename district votes
BJP Maharashtra Nagpur-East Nitin Gadkari Nagpur 1200
AAP Maharashtra Nagpur-East Arvind Kejriwal Nagpur 750
BJP Maharashtra Nagpur-West Vicky Nagpur 4800
AAP Maharashtra Nagpur-West Lucky Nagpur 3500
BJP Maharashtra Nagpur-North Rakesh Nagpur 100
AAP Maharashtra Nagpur-North Ravan Nagpur 1500
以下是我对上表的预期输出
查询仅从投票组中按参与方名称和选区选择最大vlue,并显示如下输出。
partyname Count
BJP 2
AAP 1
bcoz bjp来自那格浦尔-东部和那格浦尔西部
所以它显示计数2
而那格浦尔(ag)从那格浦尔(ag)引出-北,那么它仅显示1个计数。
请给我查询...
