How can I get all items to display as columns using SQL pivot when number of items is large?

Question

If I have a table like so:

SalesPerson Product SalesAmount
Bob         Pickles $100.00
Sue         Oranges $50.00
Bob         Pickles $25.00
Bob         Oranges          


        

Answer 1

see,i do not know you exact table design. I am just trying to give you rough idea here,And this is just main part of whole query .

 Declare @item varchar(500)
    Declare @Sql varchar(max)

    create   table t (SalesPerson varchar(50), Product varchar(50), SalesAmount float)
    insert into t values
    ('Bob','Pickles', 100.00)
    ,('Sue','Oranges', 50.00)
    ,('Bob','Pickles', 25.00)
    ,('Bob','Oranges', 300.00)
    ,('Sue','Oranges', 500.00)

    ;With CTE as
    (
     Select distinct product from t
    )

    select 

        @item=stuff((select ','+ '['+ product + ']' from cte for xml path('')),1,1,'')
     from CTE A
    print @item --debug

    set @sql=' SELECT SalesPerson, '+@item+'
    FROM 
    (SELECT SalesPerson, Product, SalesAmount
    FROM t ) ps
    PIVOT
    (
    SUM (SalesAmount)
    FOR Product IN
    ( '+@item+')
    ) AS pvt '
    print @sql --debug
    exec (@sql)
