Find the difference between two timestamps in days with MySQL
Use DATEDIFF() function from MySQL to get the difference between two timestamps in days.
The syntax is as follows −
select datediff(yourColumnName1,yourColumnName2) as anyVariableName from yourTableName;
To understand the above syntax, let us create a table. The following is the query to create a table −
mysql> create table DifferenceTimestamp −> ( −> IssueTime timestamp, −> DueTime timestamp −> ); Query OK, 0 rows affected (0.66 sec)
Insert some records in the table with the help of insert command. We are setting dates here. The query is as follows −
mysql> insert into DifferenceTimestamp values(now(),date_add(now(),interval -30 Day)); Query OK, 1 row affected (0.12 sec) mysql> insert into DifferenceTimestamp values(now(),date_add(now(),interval -24 Day)); Query OK, 1 row affected (0.16 sec) mysql> insert into DifferenceTimestamp values(now(),date_add(now(),interval -5 Day)); Query OK, 1 row affected (0.14 sec)
Display all records from the table with the help of select statement. The query is as follows −
mysql> select *from DifferenceTimestamp;
The following is the output −
+---------------------+---------------------+ | IssueTime | DueTime | +---------------------+---------------------+ | 2018-12-07 17:48:28 | 2018-11-07 17:48:28 | | 2018-12-07 17:48:40 | 2018-11-13 17:48:40 | | 2018-12-07 17:48:46 | 2018-12-02 17:48:46 | +---------------------+---------------------+ 3 rows in set (0.00 sec)
Here is the query to get difference between two timestamps in days. The query is as follows −
mysql> SELECT DATEDIFF(IssueTime, DueTime) AS DifferenceInTimestampDays from DifferenceTimestamp;
The following is the output −
+---------------------------+ | DifferenceInTimestampDays | +---------------------------+ | 30 | | 24 | | 5 | +---------------------------+ 3 rows in set (0.00 sec)
