我想查询行以查看基于上一季度月份的注册记录,例如:
当前月/年: 2018年1月
查询应按注册月份显示所有记录: 2017年10月, 2017年7月, 2017年4月等等。
我使用以下查询,但只能选择过去3个月的行。
SELECT name, date, amount, agreement, bank
FROM `account`
WHERE (YEAR(date) = YEAR(CURRENT_DATE - INTERVAL 3 MONTH) AND MONTH(date) = MONTH(CURRENT_DATE - INTERVAL 3 MONTH))

你可以像这样做算术:
# create summary data frame from HIST
df <- HIST %>%
group_by(Fonte, UF) %>%
summarise(SUMMW = sum(MW))
# calculate total bar height for each UF value, & sort accordingly.
df2 <- df %>%
group_by(UF) %>%
summarise(bar.heights = sum(SUMMW)) %>%
ungroup() %>%
arrange(desc(bar.heights))
# convert UF in the summary data frame to factor, with levels in the sorted order
df$UF <- factor(df$UF, levels = df2$UF)
rm(df2) # you can remove df2 after this; it's not needed anymore
# plot
ggplot(df,
aes(x = UF, y = SUMMW, fill = Fonte))+
theme(axis.text.x = element_text(angle = 90, hjust = 1)) +
geom_col()
您似乎理解如何处理年份组件,但类似于:
select a.*
from account a
where mod(month(date), 3) = mod(month(current_date), 3);

手动试试这个
select *
from account
Where current_date >= dateadd(year, -1, Getdate())
And Month(current_date) In (
Month(Getdate()),
(Case When Month(Getdate())+3 > 12 Then Month(Getdate())+3-12 Else Month(Getdate())+3 End),
(Case When Month(Getdate())+6 > 12 Then Month(Getdate())+6-12 Else Month(Getdate())+6 End),
(Case When Month(Getdate())+9 > 12 Then Month(Getdate())+9-12 Else Month(Getdate())+9 End)
)
