Hi,

the SQL,

SQL

SELECT CONVERT(VARCHAR(10), VRS_UTCTIME, 121) AS [Date],
MIN(SUBSTRING(CONVERT(VARCHAR(23), VRS_UTCTIME, 121), 12,20)) AS [start_time],
MAX(SUBSTRING(CONVERT(VARCHAR(23), VRS_UTCTIME, 121), 12,20)) AS [stop_time],
MAX(VRS_SPEED) AS [max_speed]
FROM STS_VEHICLE_RUNNING_STATUS
WHERE VRS_DEVICEID = 'ST0001' AND  VRS_UTCTIME BETWEEN '2012-07-02' AND '2012-11-09'
GROUP BY CONVERT(VARCHAR(10), VRS_UTCTIME, 121)

retrieve data as below,

Date            start_time      stop_time       max_speed
----            ----------      ---------       ---------
2012-07-02      10:59:26.000    11:33:36.000    40

2012-09-06      18:45:29.000    19:46:28.000    0.36

2012-10-09      12:10:12.000    01:12:12.000    50

Then, how can remove the SS(HH:MM:SS) part of start_time and stop_time using SQL?

Thanks..

Solution 2

Change the length from 20 to 5 in your SUBSTRING function calls.

Can you please try this one...

SQL

SELECT CONVERT(VARCHAR(10), VRS_UTCTIME, 121) AS [Date],
MIN(LEFT(CONVERT(VARCHAR(8),VRS_UTCTIME, 108),5)) AS [start_time],
MAX(LEFT(CONVERT(VARCHAR(8),VRS_UTCTIME, 108),5)) AS [stop_time],
MAX(VRS_SPEED) AS [max_speed]
FROM STS_VEHICLE_RUNNING_STATUS
WHERE VRS_DEVICEID = 'ST0001' AND  VRS_UTCTIME BETWEEN '2012-07-02' AND '2012-11-09'
GROUP BY CONVERT(VARCHAR(10), VRS_UTCTIME, 121)
