查询Sql Server - 显示其他查询的空白行

Question

您好我的查询有问题：

Select 'N' as Tipo,CONVERT(VARCHAR(10), Noleggio.DataInizioNoleggio, 105) as Data,DATENAME(WEEKDAY, Noleggio.DataInizioNoleggio) as GG,
Trasporto as CodArt,
Trasporto,Matricola,TipoMezzo,
'' as Totale
from Noleggio

除了这些参数，我还有一个名为 - DataTermineNoleggio

我必须在 DATA 中打印 DATAFINENOLLEGGIO 的值，在一个只包含该参数的空行中，我把它应该是结果的图像。我该怎么办？

我想你想要实现的目标：

select '',
   CONVERT(VARCHAR(10), Noleggio.DataTermineNoleggio, 105) as Data,
   '','','','','','' 
from Noleggio

但是从我可以理解，你想要一种方法来显示你的行的“开始日期”和“结束日期”...这不会更容易：

Select 'N' as Tipo,
      CONVERT(VARCHAR(10), Noleggio.DataInizioNoleggio, 105) as DataInizio,
      CONVERT(VARCHAR(10), Noleggio.DataTermineNoleggio, 105) as DataTermine,
      DATENAME(WEEKDAY, Noleggio.DataInizioNoleggio) as GG, 
      Trasporto as CodArt,
      Trasporto,
      Matricola,
      TipoMezzo,
      '' as Totale 
from Noleggio
