How to export more than 1MB in XML format using sqlcmd and without an input file?

问题

In SQL Server 2008, I want to export the result of a stored procedure to a file using sqlcmd utility. Now the end of my stored procedure is a select statement with a "for xml path.." clause at the end.

I read on BOL that if I don't want my output truncated when reaching 1MB file size, I have to use this :XML ON command, but it should be placed on its own line, before calling the stored procedure.

Does any of you experts know if it is possible to do that without specifying an input file for sqlcmd? (I'm calling sqlcmd like this:

exec master..xp_cmdshell 'sqlcmd -Q"exec storedProcedureName @param1=value1, @param2=value2" -o c:\exportResults.xml -h-1 -E',

but "storedProcedureName" and its parameters can change, which would mean 1 input file per passed parameters to sqlcmd)

Also, it seems that I can't use bcp instead of sqlcmd because my stored procedure is creating a temporary table and performing DML statements on it?

Thanks a lot

I answer my question (using powershell):

If you can use powershell as your executing shell, then you can have the :XML ON in the -Q parameter as well, just encode endline character \\n (`n in powershell)

sqlcmd -Q":XML ON\`n exec storedProcedureName @param1=value1, @param2=value2" -o c:\exportResults.xml -h-1 -E
