Winforms登录应用程序示例？(Winforms login application samples?)

 试试这个， 
 
$count = DB::table('member_profiles')
         ->select(DB::raw('floor(DATEDIFF(CURDATE(),birthday) /365) as age') ,'civil_status')
         ->where('civil_status','single')
         ->where('age','>',25)
         ->where('age','<',35)
         ->count();
 
 这里的floor功能是在十进制值的情况下向下舍入。 由于在sql中无法识别month_between因此您可以使用DATEDIFF() ，它以天为单位并将其除以365以获得年龄值。 
 
 希望你能理解。 

Try this one,
 
$count = DB::table('member_profiles')
         ->select(DB::raw('floor(DATEDIFF(CURDATE(),birthday) /365) as age') ,'civil_status')
         ->where('civil_status','single')
         ->where('age','>',25)
         ->where('age','<',35)
         ->count();
 
Here floor funtion is for rounding down in case of decimal value. Since month_between is not recognized in sql you can use DATEDIFF() which gives you in terms of days and divide it by 365 to get age value. 
 
Hope, you understand.
