Question

我想只获得一行日期：

select Datum, ZONE_2, 0 as SEEFRACHT

        from (

             select to_char(arch_p.ANKUEND_TERMIN,'dd.mm.yy') as Datum, Count (*) as ZONE_2
             from ARCH_PACKSTUECK arch_p
             where (arch_p.lbr_auf_nr like '%02')
             group by to_char(arch_p.ANKUEND_TERMIN,'dd.mm.yy')

             union all

             select to_char(ANKUEND_TERMIN,'dd.mm.yy') as Datum, Count (*) as ZONE_2
             from PACKSTUECK p
             where(p.lbr_auf_nr like '%02')
             group by to_char(p.ANKUEND_TERMIN,'dd.mm.yy')

             order by Datum           
             )

DATUM |ZONE_2|SEEFRACHT
01.02.17  5   0
01.02.17  588 0
02.02.17  52  0
02.02.17  484 0

Answer 1

试试这个

select Datum, sum(ZONE_2) as ZONE_2, 0 as SEEFRACHT
        from (

             select to_char(arch_p.ANKUEND_TERMIN,'dd.mm.yy') as Datum, Count (*) as ZONE_2
             from ARCH_PACKSTUECK arch_p
             where (arch_p.lbr_auf_nr like '%02')
             group by to_char(arch_p.ANKUEND_TERMIN,'dd.mm.yy')

             union all

             select to_char(ANKUEND_TERMIN,'dd.mm.yy') as Datum, Count (*) as ZONE_2
             from PACKSTUECK p
             where(p.lbr_auf_nr like '%02')
             group by to_char(p.ANKUEND_TERMIN,'dd.mm.yy')

             ) as t
        group by Datum           
        order by Datum
