我需要创建一个报告，我正在努力使用SQL脚本。我要查询的表是一个公司\状态\历史记录表，其中包含如下条目（我无法理解的条目）

表公司状况历史栏目：

| id | company_id | status_id | effective_date |

数据：

我想回答以下问题：“获取所有在2017年1月1日至2017年12月31日期间至少处于状态1的公司”

以上是我不知道如何处理的情况，因为我需要添加一些类型的逻辑：

“如果此行状态为1且其日期在日期范围之前，请检查下一行的日期是否在日期范围内。”
“如果此行的状态为1，且其日期在日期范围之后，请在该行之前检查其日期是否在日期范围之内。”

如果您希望查找在任何时刻处于状态1且在请求的时间段内有记录的id：
您希望在状态1和期间内查找id的情况：

如果您希望查找在任何时刻处于状态1且在请求的时间段内有记录的id：
您希望在状态1和期间内查找id的情况：

declare@range\u st date='2017-01-01'
声明日期为“2017-12-31”
挑选
案例
当csh1.status\u id=1和csh1.effective\u date时，可能这就是您要找的？对于这类问题，您需要连接表的两个实例，在本例中，我只是通过Id连接下一个记录，这可能并不完全正确。为了做得更好，您可以使用一个窗口函数（如row_number）创建一个新Id，并根据您的需求标准对表进行排序
如果此行状态为1且其日期在日期范围检查之前
如果下一行的日期在日期范围内，则显示下一行
declare@range\u st date='2017-01-01'
声明日期为“2017-12-31”
挑选
案例
当csh1.status\u id=1和csh1.effective\u date时，我建议使用cte和窗口函数行号。有了它，您可以找到所需的记录。例如：

  ,status_id INT
  ,effective_date DATETIME
)

INSERT INTO @t VALUES
