以下是我的MySQL查询
SELECT id
FROM member_measurement_records
WHERE date in (SELECT MAX(date) from member_measurement_records GROUP BY type)
我想用laravel eloquent写的。 你能帮我么。因为我是新手。

嗯，有几种方法可以做到这一点。
使用DB facade
$data = DB::table('member_measurement_records')->where('date', DB::raw("(select max(`date`) from member_measurement_records GROUP BY type)"))->get();
使用雄辩和原始查询
$data = MemberMeasurementRecords::whereRaw('date = (select max(`date`) from member_measurement_records GROUP BY type)')->get();
使用Eloquent和DB facade
$data = MemberMeasurementRecords::find(DB::table('member_measurement_records')->max('date')->groupBy('type'));

尚未测试过，但您可以尝试一下：
（假设您的相应模型称为public void printTitles(){
Date todayDate = new Date();
System.out.printf("_______________________________________");
System.out.printf("\n\t\t\tInvoice 1");
System.out.printf("\n\t\t\t\t%td-%<tb-%<tY", todayDate);
}
public void printHeaders(){
System.out.printf("\n---------------------------------------");
System.out.printf("\n| ID |\t\t\tDESC\t\t|\tAMT\t |");
System.out.printf("\n---------------------------------------");
}
public void printRows(String id, String desc, int fee) {
System.out.printf("\n| %s | %.20s| %,8d|", id, desc, fee);
System.out.printf("\n---------------------------------------");
}
public void printResult() {
System.out.printf("\n|\t Sub Total\t\t %,8d|",subTotal);
System.out.printf("\n---------------------------------------");
System.out.printf("\n|\t Tax(5%%)\t\t\t\t %,8d|", tax);
System.out.printf("\n---------------------------------------");
System.out.printf("\n|\t Total\t\t\t\t %,4d|", total);
System.out.printf("\n---------------------------------------");
System.out.printf("\n\t\t\t\tTHANK YOU!");
System.out.printf("\n_______________________________________");
}
