What is the proper way to retrieve the value stored in INT column as MySQL TIMESTAMP?

We can use FROM_UNIXTIME() function to retrieve the value, as MySQL TIMESTAMP, stored as INT in the column of a table.

For example, we have a table called ‘test123’ which has a column named ‘val1’. In this column, we stored the integer values as follows −

mysql> Select * from test123;
+------------+
| val1       |
+------------+
|     150862 |
| 1508622563 |
|  622556879 |
| 2147483647 |
+------------+
4 rows in set (0.00 sec)

Now with the help of the FROM_UNIXTIME() function, we can retrieve the column integer values in the form of MySQL TIMESTAMP data.

mysql> Select FROM_UNIXTIME(Val1) from test123;
+---------------------+
| FROM_UNIXTIME(Val1) |
+---------------------+
