SQL server 里按年按月进行累计值统计

即 4月算从1~4月的累计值

参考如下：

select dt,

account_set_ord,

account_set_title,

account_ord,

account_title,

year,

ym,

cumulative_money_J,

cumulative_money_D,

row_num

from (

SELECT

dt,

account_set_ord,

account_set_title,

account_ord,

account_title,

year,

ym,

cumulative_money_J,

cumulative_money_D,

ROW_NUMBER() OVER (PARTITION BY account_set_ord, account_set_title, account_ord, account_title, year, ym,cumulative_money_J, cumulative_money_D ORDER BY ym) as row_num

from (

SELECT

@DateThreshold as dt,

account_set_ord,

account_set_title,

account_ord,

account_title,

year,

ym,

SUM(income_money) OVER (PARTITION BY account_set_ord, account_set_title, account_ord, account_title, year ORDER BY ym) AS cumulative_money_J,

SUM(expense_money) OVER (PARTITION BY account_set_ord, account_set_title, account_ord, account_title, year ORDER BY ym) AS cumulative_money_D

FROM dws_finance_fund_balance_income_expense_month

WHERE dt = @DateThreshold

) t1

) t4

where t4.row_num = 1

采用 SUM(expense_money) OVER (PARTITION BY account_set_ord, account_set_title, account_ord, account_title, year ORDER BY ym) 来计算累计值

通过 ROW_NUMBER() OVER (PARTITION BY account_set_ord, account_set_title, account_ord, account_title, year, ym,cumulative_money_J, cumulative_money_D ORDER BY ym) as row_num 来进行过滤
