php - 添加另一个条件程序

这是我的程序。

我如何才能添加另一个条件，该条件应满足driver_latlong表中的updated_time记录应少于1分钟的条件？

这是我的程序

BEGIN
SET @sql = CONCAT(
    'SELECT (DriverLocation.updated_at - NOW()) as Diff, DriverLocation.updated_at,  NOW(), DriverLocation.AutoId, DriverLocation.DriverId,
    @dist:= ( 6371 * acos( cos( radians(',lat,') ) * cos( radians( DriverLocation.Lat ) ) * cos( radians( DriverLocation.Long ) - radians(',lng,') ) + sin( radians(',lat,') ) * sin( radians( DriverLocation.Lat ) ) ) ) AS distance
    FROM driver_latlong DriverLocation LEFT JOIN driver_details DriverDetail on DriverDetail.DriverId = DriverLocation.DriverId where DriverLocation.DriverId NOT IN (',Exclude,') AND DriverDetail.IsActive=',1,' AND DriverDetail.IsOnline=',1,'   having distance <=50000.0 ORDER BY distance ASC LIMIT 0 , 1;');
PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
END

最佳答案

如果您仅提及MySQL获得时间，即NOW()

您将获得差异介于0到60秒（1分钟）之间的记录

然后，您应该将此添加到您的程序中

AND (DriverLocation.updated_at - NOW() BETWEEN  0 AND 60 )
