SQL Server 2005 pivot query help

I'm trying out the pivot function in SQL Server 2005 for the first time and running into a wall getting the result set I desire.

I have two tables defects and employees. I'm trying to get all the defects for employees in my employee table and I don't care about any defects assigned to people outside those that are entered in my employee table (I am thinking to join to it, I have not tried a sub query yet but don't think I'll need to)

I want to get results grouped by (pivoted on) defects.severity field. The fields I want in the result set are: severity, assigne开发者_高级运维d to, employee.name, fix data

Basically I want to roll up the data according to severity and show a count based on the severity levels of defects

Here are my tables:

CREATE TABLE [dbo].[Employees]
(
    [EmployeeId] [int] NOT NULL,
    [ManagerId] [int] NULL,
    [NTID] [nvarchar](50) NOT NULL,
    [FirstName] [nvarchar](50) NOT NULL,
    [LastName] [nvarchar](50) NOT NULL,
    [FullName] [nvarchar](100) NOT NULL,
    [ReportingGroup] [nchar](10) NOT NULL,
    [Added] [datetime] NOT NULL,
    [LastUpdate] [datetime] NOT NULL,
    [UpdateBy] [nvarchar](50) NOT NULL
)

CREATE TABLE [dbo].[defects]
(
    [Defect ID] [float] NULL,
    [SubSystem] [nvarchar](255) NULL,
    [Status] [nvarchar](255) NULL,
    [Severity] [nvarchar](255) NULL,
    [FixDate] [nvarchar](255) NULL,
    [Assigned To] [nvarchar](255) NULL,
    [Summary] [nvarchar](255) NULL,
    [Product List] [nvarchar](255) NULL,
    [Development Type] [nvarchar](255) NULL,
    [Defect Category] [nvarchar](255) NULL,
    [Defect Cause] [nvarchar](255) NULL,
    [Est Ready for Retest] [nvarchar](255) NULL,
    [Fix Stage] [nvarchar](255) NULL,
    [Planned Fix in Deployment Event] [nvarchar](255) NULL,
    [Planned Fix in Event Mgmt Group] [nvarchar](255) NULL,
    [Est Fixed Date] [nvarchar](255) NULL,
    [Other Owner] [nvarchar](255) NULL
)

i got it with this SQL:

select [Assigned To], [1-Urgent],[2-High],[3-Medium],[4-Low]
from (select [assigned to],[Business Severity] from defects where [assigned to] is not null) D
pivot
(count([Business Severity]) for [Business Severity] in ([1-Urgent],[2-High],[3-Medium],[4-Low])) V

thanks all
