    Select count of type by person

    I have a database table that is a list of items. It has columns for id, type_id, date, staff_id, memo, etc. I'm trying to select the number of items (i.e. using the count() function) of each type per person. So the output table would be like:


    Name: | Count of Type 1: | Count of Type 2 | .......
    --------------------------------------------------------------------
    Chris | 3 | 2 |
    John | 2 | 1 |


    Any ideas? I think it's a matter of counting the items based on type_id and then grouping them by staff_id, but I can't seem to get it.

    Any help is appreciated! Thanks.

    its depends of what u want and use group by as u need
    for example

    PHP Code:
    //change * to what you want count to
    $sql '
    select name, count(*) as countNumber
    from table
    group by itemId
