我有以下MySQL表：

我需要获取Mvt = 60200的所有行，并将该行中的每个GC和LC记录乘以1.1，并将包含更改的新行添加回同一个表中，并将FY设置为2011.
我怎样才能在一份声明中做到这一切？ 是否有可能在1个语句中完成所有这些（我对SQL知之甚少）？ 这可以在标准SQL中完成，因为数据库将被移植到另一个数据库服务器吗？ 我不知道它将是哪个服务器。
答案 0 :(得分：9)
在标准SQL中（在特定于供应商的实现中可能有更好的方法，但我倾向于更喜欢标准的东西）：
insert into mytable (
Version, Yr_Varient, Period, CoA, Company, Item, Mvt, Ptnr_Co, Investee,
FY, GC, LC
) select
Version, Yr_Varient, Period, CoA, Company, Item, Mvt, Ptnr_Co, Investee,
2011, GC*1.1, LC*1.1
from mytable
where Mvt = 60200
-- and FY = 2010
您可能还希望根据测试结果稍微限制您的选择语句，例如取消注释上面的and FY = 2010行以停止复制所有2009和2008数据（如果有的话）。我认为你只想在GC和LC上增加10％，继续前一年的事情。
这样做的方法是运行select，根据您的请求提供FY，GC和LC的修改数据，并将所有这些行重新输入insert。

insert into mytable (
Version,Yr_Varient,FY,Period,CoA,Company,Item,Mvt,Ptnr_Co,Investee,GC,LC)
SELECT Version ,Yr_Varient,"2011" as FY, Period, CoA, Company , Item , Mvt ,Ptnr_Co , Investee , GC*1.1 as GC, LC*1.1 as LC FROM <table Name>
WHERE Mvt = 60200
答案 2 :(得分：0)
INSERT INTO _table_
(Version,
Yr_Varient,
FY,
Period,
CoA,
Company,
Item,
Mvt,
Ptnr_Co,
Investee,
GC,
LC)
SELECT
Version,
Yr_Varient,
2011,
Period,
CoA,
Company,
Item,
Mvt,
Ptnr_Co,
Investee,
GC * 1.1,
LC * 1.1
FROM
_table_
WHERE
Mvt = 60200
AND FY <> 2011
此语句应适用于任何SQL数据库。
