it is quite long and complicated and produces an accurate result.
such as:
Agent NameMondayTuesdayWednesdayThursdayFridaySaturdaySunday
Emil SookalooPresentAnnual LeaveUnknownUnknownUnknown
Irshaad KhanPresentAnnual LeaveUnknownUnknownUnknown
now
i want a result like this:
Agent NameMonday 2008/20/13Tuesday 2008/10/14WednesdayThursdayFriday 2008/10/10Saturday 2008/10/11Sunday 2008/10/12
Emil SookalooPresentAnnual LeaveUnknownUnknownUnknown
Irshaad KhanPresentAnnual LeaveUnknownUnknownUnknown
As you can see i have commented varialbles in my sp, namely the ones that start with @Ld.
my intension is to do this in the final select statement:
SELECT DISTINCT
[AgentName],
[Monday] as [Monday + ' ' + @ldmonday] ,
[Tuesday] as [Tuesday + ' ' + @ldtuesday],
[Wednesday] as [Wednesday + ' ' + @ldwednesday],
[Thursday] as [Thursday + ' ' + @ldthursday],
[Friday] as [Friday + ' ' + @ldfriday],
[Saturday] as [Saturday + ' ' + @ldfriday],
[Sunday] as [Sunday + ' ' + @ldsunday],
[Hours]
FROM @attendance
but this produces column names that are literally [Friday + ' ' + @ldfriday] for example.
i have tried this : [Friday] as @ldfriday
but it produces a syntax error.
so my question is: HOW DO I DYNAMICALLY GENERATE COLUMN NAMES USING TABLE DATA?
can someone help?

In order to dynamically generate column names, you need to have dynamically generated SQL.
Declare @SQL varchar(max)
Declare @col1Name varchar(50), ...
Set @SQL = 'Select Monday as ' + @col1Name + ' From ...'
exec sp_executesql @SQL
Just out of curiosity, though, usually something like this is better done in whatever UI is going to be displaying the results.

Hi
Thanks for your reply
to satisfy your curiousity this is displayed in a web application, BUT, the clients also include windows mobile apps and windows apps.
the datagrid that displays this data is one of thos irritating 'autogenerate column names' ones and it displays results from a number of different stored procedures.
that is why i need to generate the column names dynamically.
thanks!

This sounds like a situation where if you know the date (from the data) of the first day of the week, then you can generate a list of column names quite easily using a "tally table" whose only contents are the numbers from 1 to 7.
DECLARE @TALLY TABLE (RN int PRIMARY KEY CLUSTERED, WD varchar(9))
INSERT INTO @TALLY (RN, WD)
SELECT 1, 'Monday' UNION ALL
SELECT 2, 'Tuesday' UNION ALL
SELECT 3, 'Wednesday' UNION ALL
SELECT 4, 'Thursday' UNION ALL
SELECT 5, 'Friday' UNION ALL
SELECT 6, 'Saturday' UNION ALL
SELECT 7, 'Sunday'
DECLARE @BEGIN_DATE AS DateTime, @COLUMN_LIST AS varchar(200)
SET @BEGIN_DATE = '10/13/2008'
SET @COLUMN_LIST = ''
SELECT @COLUMN_LIST = @COLUMN_LIST +
'[' + WD + ' ' + CAST(YEAR(DATEADD(d,RN,@BEGIN_DATE)) AS char(4)) + '/' +
RIGHT('0' + CAST(MONTH(DATEADD(d,RN,@BEGIN_DATE)) AS varchar(2)),2) + '/' +
RIGHT('0' + CAST(DAY(DATEADD(d,RN,@BEGIN_DATE)) AS varchar(2)),2) +
CASE RN WHEN 7 THEN '] ' ELSE '], ' END
FROM @TALLY
SELECT @COLUMN_LIST
The above code can be adapted to allow you to specify where @BEGIN_DATE comes from.
