How to convert string to time in MySQL?

You can use format specifier. Following is the syntax −

select str_to_date(yourColumnName,'%d/%m/%Y %h:%i %p') as anyAliasName from yourTableName;

Let us first create a table −

mysql> create table DemoTable
   -> (
   -> DueDate varchar(100)
   -> );
Query OK, 0 rows affected (0.51 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values('11/02/2019 10:35');
Query OK, 1 row affected (0.20 sec)

mysql> insert into DemoTable values('21/12/2018 12:01');
Query OK, 1 row affected (0.19 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

Output

This will produce the following output −

+------------------+
| DueDate          |
+------------------+
| 11/02/2019 10:35 |
| 21/12/2018 12:01 |
+------------------+
2 rows in set (0.00 sec)
