How to model this data

Question

In the sample data below, there are rows that contain header names, followed by a row with the data.
The problem is that some of the "header" column values change.  They represent "sizes" boxes.
Name | BoxType | Color | Qty | 45 | 11 | 13.5
Compx | F | Red | 32 | 1 | 0 | 34
Name | BoxType | Color | Qty | 75 | 11 | 12.5
QuickMartZ | G | Blue | 68 | 13 | 7 | 77
Name | BoxType | Color | Qty | 75 | 11 | 45
QuickMartZ | F | Blue | 22 | 17 | 72 | 12
How could I model this data or re-shape it into a schema such as
Table
=========
AccountName
BoxType
Color
Qty
Size
Ultimately I need to be able to extract a "rolled up" count of the boxes by size and their quantity
Something like this
AccountName
BoxType
Color
Qty_Size1
Qty_Size2
Qty_Size3
Qty_Size4
Qty_Size5
Qty_SizeN...

Answer 1

Without some value which links the two rows together (other than the order of rows how do we know the box in the line above Compx belongs to it?) I don't think this is going to be possible as a set based solution.
You could use a cursor to move through the rows RBAR:
DECLARE @table TABLE (name VARCHAR(20), boxType VARCHAR(20), color VARCHAR(20), qty VARCHAR(4), col1 INT, col2 INT, col3 FLOAT)
INSERT INTO @table (name, boxType, color, qty, col1, col2, col3)
VALUES
('Name', 'BoxType', 'Color', 'Qty', 45, 11, 13.5),
('Compx', 'F', 'Red', '32', 1, 0 , 34),
('Name', 'BoxType', 'Color', 'Qty', 75, 11, 12.5),
('QuickMartZ', 'G', 'Blue', '68', 13, 7 , 77),
('Name', 'BoxType', 'Color', 'Qty', 75, 11, 45),
('QuickMartZ', 'F', 'Blue', '22', 17, 72, 12)
DECLARE @name VARCHAR(20), @boxType VARCHAR(20), @color VARCHAR(20), @qty VARCHAR(4), @col1 INT, @col2 INT, @col3 FLOAT,
@pname VARCHAR(20), @pboxType VARCHAR(20), @pcolor VARCHAR(20), @pqty VARCHAR(4), @pcol1 INT, @pcol2 INT, @pcol3 FLOAT
DECLARE @products TABLE (name VARCHAR(20), boxType VARCHAR(20), color VARCHAR(20), qty VARCHAR(4), size1 FLOAT, size2 FLOAT, size3 FLOAT)
DECLARE @boxes TABLE (name VARCHAR(20), boxType VARCHAR(20), size1 FLOAT, size2 FLOAT, size3 FLOAT)
DECLARE c1 CURSOR
FOR SELECT *
FROM @table
OPEN c1
FETCH c1 INTO @name, @boxType, @color, @qty, @col1, @col2, @col3
WHILE @@FETCH_STATUS <> -1
BEGIN
IF @name = 'name'
BEGIN
SET @pname = @name
SET @pboxType = @boxType
SET @pcolor = @color
SET @pqty = @qty
SET @pcol1 = @col1
SET @pcol2 = @col2
SET @pcol3 = @col3
END
IF @name <> 'name'
BEGIN
INSERT INTO @products (name, boxType, color, qty, size1, size2, size3) VALUES (@name, @boxType, @color, @qty, @col1, @col2, @col3)
INSERT INTO @boxes (name, boxType, size1, size2, size3) VALUES (@name, @boxType, @pcol1, @pcol2, @pcol3)
END
FETCH c1 INTO @name, @boxType, @color, @qty, @col1, @col2, @col3
END
CLOSE c1
DEALLOCATE c1
SELECT *
FROM @products
SELECT *
