How to convert varchar “time” to real time in MySQL?
For this, you can use TIME_FORMAT(). Let us first create a table −
mysql> create table DemoTable1591 -> ( -> ArrivalTime varchar(20) -> ); Query OK, 0 rows affected (0.58 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1591 values('1620');
Query OK, 1 row affected (0.09 sec)
mysql> insert into DemoTable1591 values('2345');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable1591 values('2210');
Query OK, 1 row affected (0.12 sec)Display all records from the table using select statement −
mysql> select * from DemoTable1591;
This will produce the following output −
+-------------+ | ArrivalTime | +-------------+ | 1620 | | 2345 | | 2210 | +-------------+ 3 rows in set (0.00 sec)
Here is the query to convert varchar “time” to real time in MySQL −
mysql> select TIME_FORMAT(CONCAT(SUBSTRING(ArrivalTime, 1,2), ':', SUBSTRING(ArrivalTime, 3,4)), '%h:%i') from DemoTable1591;
This will produce the following output −
+---------------------------------------------------------------------------------------------+ | TIME_FORMAT(CONCAT(SUBSTRING(ArrivalTime, 1,2), ':', SUBSTRING(ArrivalTime, 3,4)), '%h:%i') | +---------------------------------------------------------------------------------------------+ | 04:20 | | 11:45 | | 10:10 | +---------------------------------------------------------------------------------------------+ 3 rows in set (0.00 sec)
