Mysql - Join Same Rows with null entries

I have mysql table with format like this

Name - Date1 - Date2

After I got result

A - NULL - 1
A - 2 - NULL

I want to join these results as

A - 2 - 1

How t开发者_如何学Pythono achieve this ?

  SELECT Name,
         MAX(Date1),
         MAX(Date2)
    FROM tbl
GROUP BY Name
