BCP command to export table data to excel with column header

Hi Friends,
Here is a perfect running BCP command / SQL query which exports table data into excel sheet with column headers.

I spent almost 5 hrs to got it working, exporting data without column headers is a very easy job.
but the main task was getting column headers also in the first row of excel sheet..
so here is the script.. enjoy




NOTE: don't forget to replace RED elements with your local environment elements

use database
go
if object_id('spExportData_n') is not null
drop proc spExportData_n
go
create proc spExportData_n
(
@dbName varchar(100) = 'database name',
@sql varchar(8000) = 'select col1,col2,col3....col4 from table',
@fullFileName varchar(100) = 'output file path'
)
as
if @sql = '' or @fullFileName = ''
begin
select 0 as ReturnValue -- failure
return
end
-- if DB isn't passed in set it to master
select @dbName = 'use ' + @dbName + ';'
if object_id('##TempExportData') is not null
drop table ##TempExportData
if object_id('##TempExportData2') is not null
drop table ##TempExportData2
-- insert data into a global temp table
declare @columnNames varchar(8000), @columnConvert varchar(8000), @tempSQL varchar(8000)

select @tempSQL = left(@sql, charindex('from', @sql)-1) + ' into ##TempExportData ' +
substring(@sql, charindex('from', @sql)-1, len(@sql))

exec(@dbName + @tempSQL)
if @@error > 0
begin
select 0 as ReturnValue -- failure
return
end
-- build 2 lists
-- 1. column names
-- 2. columns converted to nvarchar
SELECT @columnNames = COALESCE( @columnNames + ',', '') + column_name,
@columnConvert = COALESCE( @columnConvert + ',', '') + 'convert(nvarchar(4000),'
+ column_name + case when data_type in ('datetime', 'smalldatetime') then ',121'
when data_type in ('numeric', 'decimal') then ',128'
when data_type in ('float', 'real', 'money', 'smallmoney') then ',2'
when data_type in ('datetime', 'smalldatetime') then ',120'
else ''
end + ') as ' + column_name
FROM tempdb.INFORMATION_SCHEMA.Columns
WHERE table_name = '##TempExportData'

-- execute select query to insert data and column names into new temp table
SELECT @sql = 'select ' + @columnNames + ' into ##TempExportData2 from (select ' + @columnConvert + ', ''2'' as [temp##SortID] from ##TempExportData union all select ''' + replace(@columnNames, ',', ''', ''') + ''', ''1'') t order by [temp##SortID]'

exec (@sql)

-- build full BCP query
DECLARE @bcpCommand VARCHAR(8000)
SET @bcpCommand = 'bcp " SELECT * from ##TempExportData2" queryout'
SET @bcpCommand = @bcpCommand + ' C:\Temp\test.csv -c -w -T -U sa -P sa","-CRAW'
EXEC database..xp_cmdshell @bcpCommand
if @@error > 0
begin
select 0 as ReturnValue -- failure
return
end
drop table ##TempExportData
drop table ##TempExportData2
set @columnNames =' '
set @columnConvert =' '
set @tempSQL =' '
select 1 as ReturnValue
