These two functions, Timestampdiff and timestampadd, are often used when applying.One, TimestampdiffGrammar:Timestampdiff (INTERVAL,DATETIME_EXPR1,DATETIME_EXPR2).DescriptionReturns an integer difference between a date or datetime expression Datetime_expr1 and datetime_expr2the. The unit of the result is given by the interval parameter. The parameter must be one of the following values: Frac_second. Indicates that the interval is milliseconds

Label:Today's use of the Timestampdiff () function in the project requires the processing of a single piece that scans the scan time to a current time greater than 24 hours. The following values summarize the usage of the Timestampdiff and Timestampadd functions. These two functions, Timestampdiff and timestampadd, are often used in MySQL applications. One,

One, the use of Timestampdiff (interval,datetime_expr1,datetime_expr2)Returns an integer difference between a date or datetime expression Datetime_expr1 and datetime_expr2the. The unit of the result is given by the interval parameter.Instance:Select Timestampdiff (Day,'2017-01-01','2017-01-09 ')Output results:8Select Timestampdiff (MINUTE,'2017-01-01','2017-01-09

Timestampdiff: this function can be used to set the second value across days. The time_to_sec function is only applicable to values in the current day. Use the time_to_sec function with caution if it is a subtraction of two seconds, because it only applies to the subtraction of seconds within one day. If it is more than one day, a negative number will be reduced. Therefore, use the timestampdiff func
