Time format in MySql database - mysql

Question

In the table theGlobal from MySql Database I have the field theTime set on char 50 and the field theType set on char 1.
On table theGlobal import with LOAD DATA INFILE Syntax two different .csv files.
In the first .csv file I have this row:
"T","0:01"
"B","1:05"
The format of 0:01 and 1:05 is mm:ss
In the second .csv file I have this row:
"L","00:07:10"
"L","01:21:39"
The format of 00:07:10 and 01:21:39 is hh:mm:ss
The result of import in the table theGlobal transform the mm of first .csv on the hh and the ss of first .csv on the mm.
E.g:
+---------+----------+
| theType | theTime |
+---------+----------+
| B | 1:05:00 |
| T | 0:01:00 |
| L | 00:07:10 |
| L | 01:21:39 |
+---------+----------+
I need for all rows in the field theTime the format hh:mm:ss.
+---------+----------+
| theType | theTime |
+---------+----------+
| B | 00:01:05 |
| B | 00:00:01 |
| L | 00:07:10 |
| L | 01:21:39 |
+---------+----------+
How to resolve this?
Please help me, thank you so much in advance.

Answer 1

While loading the data, you can assign it to a variable first, then do whatever with the variable and load it in the actual column. In your case this would look something like this:
LOAD DATA INFILE 'file.txt'
INTO TABLE t1
(column1, #var1)
SET column2 = TIME(STR_TO_DATE(#var1, '%i:%S'));
Adjust the STR_TO_DATE() parameter as needed. Here's a table explaining it (it's for date_format() but it's the same for str_to_date()).
Oh, and store the data in a time column, not varchar.
