官方提供的例子: testData = table(1 2 3 4 5 6 7 8 9 10 as `id,0 10 10 5 5 99 99 8 9 10 as `val) asof(cutPoints(testData.val,3),testData.val) 实际的例子: select symbol,LABORGETCASH, asof(cutPoints(int(LABORGETCASH)*100,5),LABORGETCASH) as lv from ( select date,symbol,round(LABORGETCASH \ 100000000,2) as LABORGETCASH from loadTable("dfs://stock","cn_finance_cashflow") where quarter = 'Q4'and year = 2021 ) where date = date('2021.12.31') 重点位cutPoints(x)的x必须为整数。
