What is the data type for unix_timestamp in MySQL?
The best data type for unix_timestamp in MySQL is integer. The integer data type is as follows
int(11);
The integer data type is useful for condition checking like ( > ,<= ) and indexing. The return type of unix_timestamp is an integer.
However, let us see what we get as UNIX Timestamp, when we convert datetime to timestamp.
To understand the above concept, let us first create a table. The query to create a table is as follows
mysql> create table UnixTime -> ( -> DueTime datetime -> ); Query OK, 0 rows affected (0.55 sec)
Insert records in the form of date using insert command. The query is as follows
mysql> insert into UnixTime values(now());
Query OK, 1 row affected (0.15 sec)
mysql> insert into UnixTime values('2010-10-14');
Query OK, 1 row affected (0.15 sec)
mysql> insert into UnixTime values('2020-09-24');
Query OK, 1 row affected (0.15 sec)Let us now display all records from the table using select command. The query is as follows
mysql> select *from UnixTime;
The following is the output
+---------------------+ | DueTime | +---------------------+ | 2018-12-19 10:07:11 | | 2010-10-14 00:00:00 | | 2020-09-24 00:00:00 | +---------------------+ 3 rows in set (0.00 sec)
Let us see the query to convert datetime to UNIX timestamp
mysql> select unix_timestamp(DueTime) as Output from UnixTime;
The following is the output
+------------+ | Output | +------------+ | 1545194231 | | 1286994600 | | 1600885800 | +------------+ 3 rows in set (0.00 sec)
