tsql - What is :XML ON in T-SQL query to export data into XML using SQLCMD? -

on blog post exporting info xml tsql using bcp or sqlcmd came across line of code:

:xml on select * dbo02.exceltest xml auto, elements, root('doc')

i tried using in sql query , triggering via sqlcmd in batch file, did homecoming right xml file. without :xml on returns unusual values described on webpage.

strangely enough, ssms (2008) shows wrong syntax when parsing or executing query.

what :xml on , how utilize it? , why doesn't ssms recognize line of code?

it explained in msdn page (search ":xml"): sqlcmd utility

that pages states:

xml output result of xml clause output, unformatted, in continuous stream.

when expect xml output, utilize next command: :xml on.

note sqlcmd returns error messages in usual format. notice error messages output in xml text stream in xml format. using :xml on, sqlcmd not display informational messages.

to set xml mode off, utilize next command: :xml off.

the go command should not appear before xml off command issued because xml off command switches sqlcmd row-oriented output.

xml (streamed) info , rowset info cannot mixed. if xml on command has not been issued before transact-sql statement outputs xml streams executed, output garbled. if xml on command has been issued, cannot execute transact-sql statements output regular row sets.

note :xml command not back upwards set statistics xml statement.

in ssms, if enable "sqlcmd mode" (in query menu), next error trying utilize :xml command:

scripting warning. command xml not supported. string not processed.

this due particular command not beingness needed within context of query editor.

xml tsql bcp sqlcmd sql-server-2008
