Question

我有以下sql表：

MONTH   CODE    DESCR    QTY    PRICE
201401  3641    HO       29      3829
201401  3641    IL       2      2
201401  3641    Office   34     43576
201401  3641    Other    38     424
201401  3641503 HO      2904    13584
201401  3641503 IL      2045    2833
201401  3641503 Office  106     237
201401  3641503 Other   79      129
201401  364     HO      37      182
201401  364     IL      8        9
201401  364     Office  750     1317
201401  364     Other   5        6

从这个表我想创建另一个看起来像这样的表：

  MONTH   CODE      HO_qty    IL+Office_QTY   Other_QTY    HO_Price  IL+Office_Price   Other_Price
 201401  3641       29           36(34+2)      38          3829        43578(43576+2)    424
 201401  3641503    2904         2151          79          13584       3070              129
 201401  364        37           758            5          182         1326               6

关于进场的任何指示？

Answer 1

认为这可能就是你要找的东西：

Select 
 MONTH, CODE,
 sum(case when descr in ('Office','IL') then QTY end) as `IL+Office_QTY`,
 sum(case when descr = 'HO' then QTY end) as `HO_qty`,
 sum(case when descr = 'Other' then QTY end) as `Other_QTY`,

 sum(case when descr in ('Office','IL') then PRICE end) as `IL+Office_Price`,
 sum(case when descr = 'HO' then PRICE end) as `HO_Price`,
 sum(case when descr = 'Other' then PRICE end) as `Other_Price`
from Table1
group by MONTH, CODE

根据行从MYSQL表中选择数据
