[Execute SQL Task] Error

Hi experts,


I am trying to get Columns Name from a select statement in MS SQL source. Something likes this:

declare @COLUMN_NAME varchar(max);

set @COLUMN_NAME=''

SELECT @COLUMN_NAME=@COLUMN_NAME+','+COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME='XXX' and COLUMN_NAME not in ('TimeStamp')

select @COLUMN_NAME as ColsList

I use ExecuteSQLTask to get the result set with result name @COLUMN_NAME along with ADO.NET connection type.
And I got a task failed error which is described below:

[Execute SQL Task] Error: An error occurred while assigning a value to variable "strPkgInsertColNames": "Unable to find column  ColsList in the result set.".

Please help me to fix this error, thanks alot

Best Rgds,
