cross-tabulation

Hi,

I tried to search posts, but I only found solutions for SQL Server/Access. I need a solution to MYSQL (5.X).

I have a table with 3 columns: hostid, itemname, itemvalue. If I do a select, it will return

How do I query the database to return something like

   A    B    C
1  10   3
2  9         40
