这个需求
mysql
SELECT count(*),left(carno,1) carno,create_time from smartsite_car_manager scm
GROUP BY left(carno,1)
HAVING DATE_FORMAT( scm.create_time, ‘%Y%m’ ) = DATE_FORMAT( CURDATE( ) , ‘%Y%m’ )
查询结果
把查询出来的carno传过 checkAddressByCarCard（carno）；查出来了
private static void checkAddressByCarCard(String no){
String licensePlate[]={“冀”,“晋”,“蒙”,“辽”,“黑”,“吉”,“苏”,“沪”,“浙”,“皖”,“闽”,“赣”,“鲁”,“豫”,“鄂”,“湘”,“粤”,“桂”,“琼”,“渝”,“川”,“黔”,“滇”," 陕",“甘”,“青”,“宁”,“新”};
String region[]={“河北”,“山西”,“内蒙古”,“辽宁”,“黑龙江”,“吉林”,“江苏”,“浙江”,“安徽”,“福建”,“江西”,“山东”,“河南”,“湖北”,“湖南”,“广东”,“广西”,“海南”,“重庆”,“四川”,“贵州”,“云南”,“陕西”,“甘肃省”,“宁夏”,“新疆”};
int index = 0;
for(int i = 0;i<11;i++){
if(no.equalsIgnoreCase(licensePlate[i])){
index=i;
System.out.println(“车辆所在地为：”+region[i]);
}
}
}
