Answer : How to create a pivot table in SQL Server 2005

is status a char field ? remove it...
what are the column names of your numeric items?
yes there are pivot/unpivot extensions to the select statement ...
however you need dynamic sql to use them...
my gut feel to that is to still use the technique i described above or this procedure...
http://www.microsoft.com/sql/ce/techinfo/20bol.asp
EXEC sp_TRANSFORM 'SUM','PM_EmpAssignedID','vw_Loc_Pos_Dflt_Rem2','PM_PositionsID','Position'
IF OBJECT_ID('sp_Transform', 'P') IS NOT NULL
DROP PROCEDURE sp_Transform
GO
CREATE PROCEDURE sp_TRANSFORM
/*
Purpose: Creates a Pivot(tm) table for the specified table,
view or select statement
Author: [email protected]
Version: 1.1
History: march 2000 version 1.0
july 2002 version 1.1
Input parameters:
@Aggregate_Function (optional)
the aggregate function to use for the pivot
default function is SUM
@Aggregate_Column
name of column for aggregate
@TableOrView_Name
name of table or view to use
if name contains spaces or other special
characters [] should be used
Can also be a valid SELECT statement
@Select_Column
Column for first column in result table
for this column row values are displayed
@Pivot_Column
Column that is transformed into columns
for this column column values are displayed
@DEBUG
Set this flag to 1 to get debug-information
Example usage:
Table given aTable
content: Product Salesman Sales
P1 Sa 12
P2 Sb 10
P2 Sb 3
P3 Sa 12
P1 Sc 8
P3 Sa 1
P2 Sa NULL
CALL
EXEC sp_Transform 'SUM', 'Sales', 'aTable', 'Product', 'Salesman'
or EXEC sp_Transform @Aggregate_Column='Sales', @TableOrViewName='aTable',
@Select_Column='Product', @Pivot_Column='Salesman'
Result:
Product| Sa | Sb | Sc | Total
-------+----------+----------+---------+---------
P1 | 12,00 | 0,00 | 8,00 | 20,00
P2 | 0,00 | 13,00 | 0,00 | 13,00
P3 | 13,00 | 0,00 | 0,00 | 13,00
