Question

此代码在Microsoft SQL Server Management Studio 2008中作为SQL查询运行时有效，但是当设置为“作业”步骤时，则仅适用于第二个条件（更新时间不是月份的最后一天）。这段代码有什么问题？

 --set next invoice date
    declare @data nvarchar(10) --invoice date
    set @data = CONVERT (date, GETDATE());

    update table 
    set invoice_date = case when day(DATEADD(day,1,@data)) = 1 then --is last day of month
                                    (SELECT convert(date,DATEADD(s,-1,DATEADD(mm, DATEDIFF(m,0,GETDATE())+1,0)))) -- set inovice date as last day of next month
                          else --is not last day of month
                                    (select DATEADD(MM,1,@data)) --add one month to inovice date
                            end
    where status = 'current' and invoice_date = @data  -- only for current inovices

试试这个。第一个条件仅适用于去年的每个月。

--set next invoice date
DECLARE @data NVARCHAR(10) --invoice date
SET @data = CONVERT (DATE, GETDATE());

UPDATE table 
SET invoice_date = CASE WHEN DAY(DATEADD(DAY,1,@data)) = 1 
                   THEN --is last day of month
                      CAST( DATEADD(s,-1,DATEADD(mm, DATEDIFF(m,0,@data)+2,0)) AS DATE) -- set inovice date as last day of next month
                   ELSE --is not last day of month
                     (DATEADD(MM,1,@data)) --add one month to inovice date
                        END
WHERE status = 'current' AND invoice_date = @data  -- only for current inovices
