dynamic field name in sql

I have a SPROC that displays data from a table. This table has a column for each month (Jan, Feb, Mar,...)
The information within the DB is displayed on our MOSS2007 site via a data grid view. 3 months are displayed...Last Month, 2 months prior, and 3 months prior.
For example in July the SPROC and the webpage displays Apr, May, and June and change automatically every month. No work required on our end.
As far as the data goes this works fine, however the column names are displayed as whatever I name them I need them to dynamically change when the month chages.

My question is can you declare and set a variable and name the column the variable you declare? I have attached the SPROC below for you to look at.

Thanks for your help...
Chris.

Additionally I have tried the below code but get the following error...
I added a Declare @MYMONTH and a set @MYMONTH statement and tried to use "AS @MYMONTH"

Incorrect syntax near '@MYMONTH'.

I would do that more like this (see code snippet).  You are getting error currently because you have the variable @MYMONTH as the name of the column which is not allowed.

You can use dynamic SQL to do that. Check this out:

To change the columns dynamically, you have two choices:

1. Maintain 12 versions of the SQL and run the appropriate one.   Probably not what you are asking for.

2. Use dynamic SQL.  Following is an example of how to change the code. The example only shows 1 column, but I think you can extrapolate to the others:

DECLARE @SQL VARCHAR(4000)

SET @SQL = 'Select  Department, Description,
(case
when month(current_timestamp) = 1 then Dec
when month(current_timestamp) = 2 then Jan
when month(current_timestamp) = 3 then Feb
when month(current_timestamp) = 4 then Mar
when month(current_timestamp) = 5 then Apr
when month(current_timestamp) = 6 then May
when month(current_timestamp) = 7 then Jun
when month(current_timestamp) = 8 then Jul
when month(current_timestamp) = 9 then Aug
when month(current_timestamp) = 10 then Sept
when month(current_timestamp) = 11 then Oct
when month(current_timestamp) = 12 then Nov
end
) as  '


--folllowing is the part that generates the column name dynamically
SET @SQL= @SQL +
case
when month(current_timestamp) = 1 then 'Dec'
when month(current_timestamp) = 2 then 'Jan'
when month(current_timestamp) = 3 then 'Feb'
when month(current_timestamp) = 4 then 'Mar'
when month(current_timestamp) = 5 then 'Apr'
when month(current_timestamp) = 6 then 'May'
when month(current_timestamp) = 7 then 'Jun'
when month(current_timestamp) = 8 then 'Jul'
when month(current_timestamp) = 9 then 'Aug'
when month(current_timestamp) = 10 then 'Sept'
when month(current_timestamp) = 11 then 'Oct'
when month(current_timestamp) = 12 then 'Nov'
end
--

SET @SQL = @SQL + ', Owner from dbo.tablename
where year = ''2009'''

EXEC (@SQL)
END

Thanks dqmq that seems to work for the single month...but I am still new to SQL and a little confused on how to display the three months and make sure that all 12 months will work as we go thru the year.

Do I need to recreate your code above for EACH month? I tried to copy your code and change the months but I still only get the one column.

Thanks again and sorry that you have to hold my hand thru this...:)

Why not just use the method I showed without dynamic SQL?

The example code that you have does not dynamically change the field names. on your code I would stll call the fields "as One_Month_Prior" I need them to be the name of the month that is actually being displayed.

Sorry

In Dynamic SQL you can do something like this. This will change the column names dynamically for all columns
ALTER PROCEDURE [dbo].[SPUnit_WIGs10]
 
AS
BEGIN
 
DECLARE @MYMONTH char(4)
SET @MYMONTH = Month(CURRENT_TIMESTAMP -60)
 
EXEC

(case 
when month(current_timestamp) = 1 then Dec
when month(current_timestamp) = 2 then Jan
when month(current_timestamp) = 3 then Feb

when month(current_timestamp) = 5 then Apr
when month(current_timestamp) = 6 then May
when month(current_timestamp) = 7 then Jun
when month(current_timestamp) = 8 then Jul
when month(current_timestamp) = 9 then Aug
when month(current_timestamp) = 10 then Sept
when month(current_timestamp) = 11 then Oct
when month(current_timestamp) = 12 then Nov
end
) as '+DateName(Month,CURRENT_TIMESTAMP-30)+', 
(case 
when month(current_timestamp) = 1 then Nov
when month(current_timestamp) = 2 then Dec
when month(current_timestamp) = 3 then Jan
when month(current_timestamp) = 4 then Feb

when month(current_timestamp) = 7 then May
when month(current_timestamp) = 8 then Jun
when month(current_timestamp) = 9 then Jul
when month(current_timestamp) = 10 then Aug
when month(current_timestamp) = 11 then Sept
when month(current_timestamp) = 12 then Oct

This will result in the following SQL being executed:
Select  Department, Description, Jun, May, Apr, Owner From dbo.Unit_WIGS2 where year = 2009

Next month, this will adjust automatically.  If your column names are not all 3 characters, as it looks like september is sept, then you can do this:


USE [GSFC_Wigs]
GO
/****** Object:  StoredProcedure [dbo].[SPUnit_WIGs10]    Script Date: 07/02/2009 10:41:52 ******/

Oh, thats right! I wasn't even looking at the sql. You do not need the case staement since we are using DATENAME formula to get the Month name.
mwvisa1's solution should be what you are looking for.

We all agree: use dynamic SQL.  We all agree to generate the month name column headers from the current_timestamp.  

The difference is whether to use a case statement to generate the month name or to use the datename function (note: you could also use the convert function).   The case statement is more cumbersome, but it gives you complete control of the month names.  For example, in your question you have "Aug" for August and "Sept" for September.   The case statement can be used to reproduce those names, whereas the datename function is not quite so flexible, always returning 3 characters in the solutions provided.  

While I proposed the case, I would go with the less cumbersome approach if the resulting month names are acceptable.  

>Do I need to recreate your code above for EACH month?
For the CASE approach, you need to add the other two columns into the SQL you are constructing.  It's basically, a copy/paste of the prior month column and then subtracting more days from the other month columns.  

One more thing, VERY IMPORTANT: note that in all the solutions you are subtracting 30-60-90 DAYS from current_timestamp to derive the month. That is not a good general solution--for example, will not work well when 28, 29, or 31 day months are involved.  You really should subtract months.  Instead of:

Current_Timestamp - 30
Current_Timestamp - 60
Current_Timestamp - 90

use this:

DateAdd (M,-1,Current_Timestamp)
DateAdd (M,-2,Current_Timestamp)
DateAdd (M,-3,Current_Timestamp)

I agree with dgmg.  You can think of March as a good argument against subtracting 30 to get previous month as you could end up in January since February only has 28-9 days.  Use the DateAdd as shown.

Note you can pull the 2009 from the current timestamp as well.
