Sql server 如何获得第一&；SQl Server表中表行的最后一次访问

需要这样的结果（其中速度=0）

试试这个：

First-OccurrenceDate  Last-OccurrenceDate
04/01/2015            06/01/2015 

SELECT MIN(Date) AS First-OccurrenceDate, MAX(Date) AS Last-OccurrenceDate
FROM   MYTABLE
WHERE  SPEED = 0

试试这个：

First-OccurrenceDate  Last-OccurrenceDate
04/01/2015            06/01/2015 

SELECT MIN(Date) AS First-OccurrenceDate, MAX(Date) AS Last-OccurrenceDate
FROM   MYTABLE
WHERE  SPEED = 0
