Split one column record into two columns in MysQL or PHP

I have a problem with the data section from the attendance machine. Data source after exporting from it as follows:

id name att
1 John 01/04/2015 7:59:00
1 John 01/04/2015 17:44:00
1 John 02/04/2015 7:50:00
1 John 04/02/2015 18:14

Where the entry (entry and exit) from the fingerprint time is saved in one column. And I want to split the data like this:

id name in out
1 John 01/04/2015 7:59:00 01/04/2015 17:44:00
1 John 02/04/2015 7:50:00 02/04/2015 18:14:00

How do I split these records into 2 columns in MySQL or PHP (maybe)? Thank.

Assuming there is only one I / O per day, this is as easy as self-connecting on a date and greater time.

select t1.id, t1.name, t1.att as `in`, t2.att as `out`
  from table1 t1
    inner join table1 t2
      on date(t1.att) = date(t2.att) and t1.id = t2.id
        and t2.att > t1.att

demo sql



If you want to create a new table with this data to get rid of the import, you just need to use this query as input create table

, for example:

create table new_table
  as
    select t1.id, t1.name, t1.att as `in`, t2.att as `out`
      from table1 t1
        inner join table1 t2
          on date(t1.att) = date(t2.att) and t1.id = t2.id
            and t2.att > t1.att

You can try this.



        SELECT a.userID,a.name,min(a.att)as `in`,max(a.att) as `out`
        FROM
            (
                SELECT userID,name,str_to_date(att,'%m/%d/%Y%T') as att,str_to_date(att,'%m/%d/%Y') as attd
                FROM attendance
            ) as a
        GROUP BY a.userID,a.attd
