mysql count and group by

I have a table as follows:

id       name
1        Complete
2        Incomplete
2        Incomplete
1        packaged
3        complete
4        packaged
4        packaged

How can I do a count statement to get the following output:
complete  2
incomplete 1
packaged 2

The reason that "incomplete" is 1 is because it is grouped by id, the same is with "packaged".  Can someone let me know how I can get a count of "name"  by grouping by 'id" ?

Thank you,
A

you have to "distinct" first:
select name , count(*)
  from ( select id, name from yourtable group by id, name )
group by name

I am getting this error "Every derived table must have its own alias". What does this mean?

Guy Hengel [angelIII / a3]Billing EngineerCommented:
it means the subquery needs an alias:
select name , count(*)
  from ( select id, name from yourtable group by id, name ) SQ
group by name 

Open in new window

SQ is the alias name given to the subquery.
side note about "aliases" for columns and tables in general:
