C# SQL查询中“

我想获取sql表列值time\u start\u int在time\u end\u int之间的值

我犯了一个错误

---

“附近的语法不正确您无法写入要在两值查询之间获取的开始。 但您键入的代码在sql中语法不正确，这不是C语言的问题

"...and start_cd >= " + time_start_int + " and " + start_cd + " <= " + time_end_int

测试此代码：

 SELECT [ID]
      ,[Available]
      ,[Type]     
  FROM [dbo].[Going]
  where start_cd !=0 or end_cd!=0 and time_end_int <= start_cd <= time_start_int

希望能对您有所帮助。

不要连接字符串，这会使您容易受到SQL注入的影响。请转换int-ti字符串，然后连接字符串。我不知道您的数据，所以说起来有点困难。

 SELECT [ID]
      ,[Available]
      ,[Type]     
  FROM [dbo].[Going]
  where start_cd !=0 or end_cd!=0 and time_end_int <= start_cd <= time_start_int 

    SELECT [ID]
      ,[Available]
      ,[Type]   FROM [dbo].[Going]
  where start_cd !=0 or end_cd!=0 and (time_end_int <= start_cd and  start_cd <= time_start_int)
