  I am working with MS SQL Server (2000), and I have a table that looks something like this:

  Meter_Name	Local_Meter_ID	Daily_Hours	Integrator_Value	Reading_Date	Legacy_ID
  A	Area1	24	712	10/10/2006	25A
  B	Area2	24	488	10/10/2006	25B
  C	Area3	24	644	10/10/2006	42C
  D	Area4	24	512	10/10/2006	54D
  E	Area5	24	256	10/10/2006	62E
  F	Area6	24	788	10/10/2006	71F
  A	Area1	16	728	10/9/2006	25A
  B	Area2	20	508	10/9/2006	25B
  C	Area3	22	666	10/9/2006	42C
  D	Area4	24	536	10/9/2006	54D
  E	Area5	24	280	10/9/2006	62E
  F	Area6	24	812	10/9/2006	71F

   

  I would like to run a query which results in something like this:

  Meter_Name	Local_Meter_ID	Legacy_ID	Daily_Hours 10/10/2006	Integrator_Hours 10/10/2006	Daily_Hours 10/9/2006	Integrator_Hours 10/9/2006
  A	Area1	25A	24	712	16	728
  B	Area2	25B	24	488	20	508
  C	Area3	42C	24	644	22	666
  D	Area4	54D	24	512	24	536
  E	Area5	62E	24	256	24	280
  F	Area6	71F	24	788	24	812

   

  If I knew how to create field names from selected data on the fly, I might have gotten this. 

  Incidentally, there will be 90 days of "history" arranged to the right of each meter in the finished product.

  Thanks

  Rob

  Perhaps you can do something with this. You can find the whole thread on http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=6216.

  CREATE PROCEDURE crosstab 
  @select varchar(8000),
  @sumfunc varchar(100), 
  @pivot varchar(100), 
  @table varchar(100),
  @where varchar(1000)=null
  AS
  
  DECLARE @sql varchar(8000), @delim varchar(1)
  SET NOCOUNT ON
  SET ANSI_WARNINGS OFF
  
  EXEC ('SELECT ' + @pivot + ' AS pivot INTO ##pivot FROM ' + @table + ' WHERE 1=2')
  EXEC ('INSERT INTO ##pivot SELECT DISTINCT ' + @pivot + ' FROM ' + @table + ' WHERE ' 
  + IsNull(@where,'1=1') + ' AND ' + @pivot + ' Is Not Null')
  
  SELECT @sql='',  @sumfunc=stuff(@sumfunc, len(@sumfunc), 1, ' END)' )
  
  SELECT @delim=CASE Sign( CharIndex('char', data_type)+CharIndex('date', data_type) ) 
  WHEN 0 THEN '' ELSE '''' END 
  FROM tempdb.information_schema.columns 
  WHERE table_name='##pivot' AND column_name='pivot'
  
  SELECT @sql=@sql + '''' + convert(varchar(100), pivot) + ''' = ' + 
  stuff(@sumfunc,charindex( '(', @sumfunc )+1, 0, ' CASE ' + @pivot + ' WHEN ' 
  + @delim + convert(varchar(100), pivot) + @delim + ' THEN ' ) + ', ' FROM ##pivot
  
  DROP TABLE ##pivot
  
  SELECT @sql=left(@sql, len(@sql)-1)
  SELECT @select=stuff(@select, charindex(' FROM ', @select)+1, 0, ', ' + @sql + ' ')
  
  EXEC (@select)
  SET ANSI_WARNINGS ON
