按一列返回数据的存储过程-sql 2012

我正在sql 2012中运行此存储过程。当时的日期范围是2014-01-01到2014-02-01。我正在对2014年1月的31天进行滚动计算。SP的求和正确，但我的结果集与之相差一天。它不会返回2014年1月1日，而是返回2014年2月1日。正在对每个录制的应用一个全日制戳记，因此我正在进行一次中间测试。此逻辑在某些SP中工作正常，而在其他SP中则处于关闭状态

有人有什么建议吗

@Y@StartDate Date=Convert（varchar（10），DateAdd（d，-50，getdate（）），110）

2014年2月21日（您的问题发布时）计算至2014年1月2日。@Today使用您的公式计算至2月2日。我想你只需要调整你的偏移量
