Experts,

What is the basic SYNTAX to use for a DYNAMIC Pivot Table in SQL Server 2008?

My table looks like this:

HOSP_NAME, SUPPLIER, TOTAL_SPEND, CROSS_REF_SPEND, NOT_CROSS_REF_SPEND

I need to have a pivot like this:

 ------------------------------------ SUPPLIER_1_____SUPPLIER_2____SUPPLIER_3
HOSP_NAME_1                             10000.00                1000.00                 10.00
HOSP_NAME_2                             10000.00                1000.00                 10.00
HOSP_NAME_3                             10000.00                1000.00                 10.00
               

I need the SUPPLIER column heading to be the actual NAMES of the SUPPLIERS

you didn't specify from what column the figures are coming from, so I've assumed they are comming from Total_spend column
basically you do it like this:

DECLARE @strSQL VARCHAR(MAX) 
DECLARE @COLS NVARCHAR(2000) 
  
SELECT @COLS = STUFF((SELECT  distinct '], [' + Supplier  
                                FROM yourtable ORDER BY 1
                                FOR XML PATH('') 
                                ), 1, 2, '') + ']' 
  
  
set @strSQL = 'select Hosp_name, ' + @COLS + ' from 
                (select Hosp_name, Supplier, Total_spend from yourtable) o 
                pivot(max(Total_spend) for Supplier in (' + @cols + '))p' --change max to sum if that's your requirement
  
exec(@strSQL)

oops, typo
DECLARE @strSQL VARCHAR(MAX) 
DECLARE @COLS NVARCHAR(2000) 
  
SELECT @COLS = STUFF((SELECT  distinct '], [' + Supplier  
                                FROM yourtable ORDER BY 1
                                FOR XML PATH('') 
                                ), 1, 2, '') + ']' 
  
  
set @strSQL = 'select Hosp_name, ' + @COLS + ' from 
                (select Hosp_name, Supplier, Total_spend from yourtable) o 
                pivot(max(Total_spend) for Supplier in (' + @cols + ')) as p' --change max to sum if that's your requirement
  
exec(@strSQL)
