在MySQL中将"12684041234"与您要执行的最长前缀匹配

SELECT num_prefix
FROM nums
WHERE '12684041234' LIKE CONCAT(num_prefix, '%')
AND LENGTH(num_prefix) = (
    SELECT MAX(LENGTH(num_prefix))
    FROM nums
    WHERE '12684041234' LIKE CONCAT(num_prefix, '%')
)

表nums有一个以num_prefix前缀值命名的列.

我怎么能在蜂巢中做到这一点？

基于区域设置,我需要找到一周中的第一天(星期日/星期一)在JAVA中,我会这样做:

Calendar FR_cal = Calendar.getInstance(Locale.FRANCE);
Calendar CA_cal = Calendar.getInstance(Locale.CANADA);

DateFormatSymbols dfs = new DateFormatSymbols();
String weekdays[] = dfs.getWeekdays();

System.out.println(weekdays[JO_cal.getFirstDayOfWeek()]);
System.out.println(weekdays[FR_cal.getFirstDayOfWeek()]);

我怎么能在python中做到这一点？

scala> "Foo".capitalize(2)    
res18: Char = o
