I'd like a custom export file from mySQL.
I have a table:
name . number . class
--------------------------------
name1 . 100 . 1
name2 . 101 . 3
name1 . 100 . 5
Now i'd like to export this data into a excel file.
But where it is duplicate number i'd like to concat the class data.
Output from table above would be:
name1 100 1 5
name2 101 3
The classes should be seperated with whitespace.
Is this possible?
Maby i have to create another table and concat the data in the first step, and later export that table?

Use GROUP_CONCAT
SELECT name, number,GROUP_CONCAT(class SEPARATOR ' ') FROM table1 GROUP BY name
