Convert INT to DATETIME in MySQL?
You can use the in-built function from_unixtime() to convert INT to DATETIME. The syntax is as follows −
SELECT FROM_UNIXTIME(yourColumnName,’%Y-%m-%d') as AnyVariableName from yourTableName;
To understand the above syntax, let us first create a table. The query to create a table is as follows −
mysql> create table IntToDateDemo -> ( -> Number int -> ); Query OK, 0 rows affected (0.59 sec)
Insert some records in the table using insert command. The query to insert record is as follows −
mysql> truncate table IntToDateDemo; Query OK, 0 rows affected (4.11 sec) mysql> insert into IntToDateDemo values(1545284721); Query OK, 1 row affected (0.19 sec) mysql> insert into IntToDateDemo values(1576820738); Query OK, 1 row affected (0.19 sec) mysql> insert into IntToDateDemo values(1513748752); Query OK, 1 row affected (0.24 sec) mysql> insert into IntToDateDemo values(1671515204); Query OK, 1 row affected (0.18 sec)
Now you can display all records from the table using select statement. The query is as follows −
mysql> select *from IntToDateDemo;
Output
+------------+ | Number | +------------+ | 1545284721 | | 1576820738 | | 1513748752 | | 1671515204 | +------------+ 4 rows in set (0.00 sec)
Here is the query that converts int to datetime using from_unixtime() function. The query is as follows −
mysql> select from_unixtime(Number,'%Y-%m-%d') as DateDemo from IntToDateDemo;
The following is the output displaying the converted datetime −
+------------+ | DateDemo | +------------+ | 2018-12-20 | | 2019-12-20 | | 2017-12-20 | | 2022-12-20 | +------------+ 4 rows in set (0.00 sec)
