Strange Behaviour in a stored Procedure

Question

Hello forum
I am attempting to build an execute script as a part of a wider process.  essentially data is imported into a temporary table and then exported via bcp; so in order to capture the column headings I am using a cursor to build a string and then execute
it.  However, if I "PRINT" the script the script is correct, but if I "EXECUTE" either with EXECUTE or sp_executesql, the script is incorrect.
Here is the Code: -
Set
@ColNameScript =(Select
'Select ')
Set
@TotalCol =(Select
count
from syscolumns
where id
in
(select id
from sysobjects
where
name='voltemp'))
Set
@CurrentCol=1
Declare
Column_Curs Cursor
for
select
name
from syscolumns
where id
in
(select id
from sysobjects
where
name='voltemp')
Open
Column_Curs
Fetch
Next
From Column_Curs
Into @ColumnName
While
@@Fetch_Status=0
Begin
IF @CurrentCol<>
@TotalCol
BEGIN
Set @ColNameScript
=(Select @ColNameScript
+ 
'^'
+ @ColumnName
+'^'
+
' AS ['
+ @ColumnName
+
END
IF @CurrentCol=
@TotalCol
BEGIN
Set @ColNameScript
=(Select @ColNameScript
+ 
'^'
+ @ColumnName
+'^'
+ 
' AS ['
+ @ColumnName
+
'] INTO COLNAMETEMP')
END
Fetch
Next
From Column_Curs
Into @ColumnName
Set @CurrentCol=@CurrentCol+1
End
Close
Column_Curs
Deallocate
Column_Curs
SELECT
REPLACE
(@ColNameScript,
'^','''')
PRINT
@ColNameScript
EXECUTE
@ColNameScript;
If I comment out the EXECUTE command the script is printed as thus: -
Select
'territoryName'
AS [territoryName],'organisation'
AS [organisation],'displayname'
AS [displayname],'URN'
AS [URN],'vacancyid'
AS [vacancyid],'jobtitle'
AS [jobtitle],'Displayfrom'
AS [Displayfrom],'displayto'
AS [displayto],'date'
AS [date],'Advert/vacancytype'
AS [Advert/vacancytype],'Type(s)
of Work' AS [Type(s) of Work],'status'
AS [status],'PageViews'
AS [PageViews],'Total
Interaction' AS [Total Interaction],'Advert
Run' AS [Advert Run],'Job
Live Days' AS [Job Live Days],'Click
through rate' AS [Click through rate],'Days
to go' AS [Days to go],'Clicks
per day' AS [Clicks per day]
INTO COLNAMETEMP
If I include the EXECUTE command the script is printed as thus: -
Select
^territoryName^
AS [territoryName],^organisation^
AS [organisation],^displayname^
AS [displayname],^URN^
AS [URN],^vacancyid^
AS [vacancyid],^jobtitle^
AS [jobtitle],^Displayfrom^
AS [Displayfrom],^displayto^
AS [displayto],^date^
AS [date],^Advert/vacancytype^
AS [Advert/vacancytype],^Type(s)
of Work^
AS [Type(s) of Work],^status^
AS [status],^PageViews^
AS [PageViews],^Total
Interaction^
AS [Total Interaction],^Advert
Run^
AS [Advert Run],^Job
Live Days^
AS [Job Live Days],^Click
through rate^
AS [Click through rate],^Days
to go^
AS [Days to go],^Clicks
per day^
AS [Clicks per day]
INTO COLNAMETEMP

Your script is confusing, as is your description.  First the script.  At the end of the loop, you do 3 things.  You select the string, you print the string, and then you execute the string.  The first select statement will change the
contents of the string TEMPORARILY in the resultset, but it does not change the content of the string.  It seems that you should have updated the string to do this. 
Your execute attempt shouldn't work at all, since you need to enclose the string in parentheses.  So something isn't matching between the script and your discussion.  As an example:
set nocount on;
if object_id('COLNAMETEMP') is not null
drop table COLNAMETEMP;
go
DECLARE @script varchar(2000);
set @script = 'Select ^territoryName^ AS [territoryName],^organisation^ AS [organisation],^displayname^ AS [displayname],^URN^ AS [URN],^vacancyid^ AS [vacancyid],^jobtitle^ AS [jobtitle],^Displayfrom^ AS [Displayfrom],^displayto^ AS [displayto],^date^ AS [date],^Advert/vacancytype^ AS [Advert/vacancytype],^Type(s) of Work^ AS [Type(s) of Work],^status^ AS [status],^PageViews^ AS [PageViews],^Total Interaction^ AS [Total Interaction],^Advert Run^ AS [Advert Run],^Job Live Days^ AS [Job Live Days],^Click through rate^ AS [Click through rate],^Days to go^ AS [Days to go],^Clicks per day^ AS [Clicks per day] INTO COLNAMETEMP'
EXEC @script;
go
DECLARE @script varchar(2000);
set @script = 'Select ^territoryName^ AS [territoryName],^organisation^ AS [organisation],^displayname^ AS [displayname],^URN^ AS [URN],^vacancyid^ AS [vacancyid],^jobtitle^ AS [jobtitle],^Displayfrom^ AS [Displayfrom],^displayto^ AS [displayto],^date^ AS [date],^Advert/vacancytype^ AS [Advert/vacancytype],^Type(s) of Work^ AS [Type(s) of Work],^status^ AS [status],^PageViews^ AS [PageViews],^Total Interaction^ AS [Total Interaction],^Advert Run^ AS [Advert Run],^Job Live Days^ AS [Job Live Days],^Click through rate^ AS [Click through rate],^Days to go^ AS [Days to go],^Clicks per day^ AS [Clicks per day] INTO COLNAMETEMP'
set @script = REPLACE (@script, '^','''')
EXEC (@script);
select * from COLNAMETEMP;
go
