Answer 1

试试这个：

select datename(month, PackageDate) + ' ' + convert(varchar, year(PackageDate)),
    stuff((
            select ',' + convert(varchar, day(PackageDate))
            from tbl_PackageDate
            where datename(month, t2.PackageDate) = datename(month, PackageDate)
                and year(PackageDate) = year(t2.PackageDate)
                and Packageid = 86
            order by PackageDate
            for xml path('')
            ), 1, 1, '')
from tbl_PackageDate t2
where Packageid = 86
group by datename(month, PackageDate),
    year(PackageDate);
