1 个工作日回到 SQL DB2

Question

我需要 select 来自数据库的数据，日期是过去一天但在工作日。是否有特定的功能（Excel 有公式 =Workday）？

我正在使用 VBA 指令将数据从 DB2 下载到 excel。

这是我用于日历日的代码。

strSQL = "SELECT *"
strSQL = strSQL & " FROM PDB2I.DI_HIS_EXH_RAT_01"
strSQL = strSQL & " WHERE CAR_DT = CURRENT DATE - 1 DAY"

提前感谢任何指示

Answer 1

检查星期几并相应更改

select * from table_x where timestamp_x > (select PREV_WEEKDAY from(select sysdate as current_date,
       case when to_char(sysdate,'D') in (1,2,7)
            then next_day(sysdate-7,'Friday')
            else sysdate-1 end as prev_weekday
from dual))

Answer 2

select * 
from mytable 
where mydate = current date - 
    (case when dayofweek(current date) = 1 then 2 -- sonntag
          when dayofweek(current date) = 2 then 3 -- montag
          else 1 end) days
