sql server 2008 - How can I nest stored procedures that return XML using FOR XML PATH? -

i have xml path stored procedure returns xml in usual manner (shortened clarity):

create procedure sp_returnsubnode begin select subnode.subnodeid "@subnodeid" ,subnode.somedata "somedata" subnode xml path('subnode') end

i have stored procedure include results of above query within e.g.

create procedure sp_returnmainxml begin select node.nodeid "@nodeid" ,node.nodedata "data" ,[at point phone call sp_returnsubnode , nest it] ,node.moredata "moredata" node xml path ('node') end

but methods have tried assigning results of executing sp_subnode xml datatype , attempting nest have failed.

this seems people want haven't found reference on how it. possible?

you can user defined functions returns xml.

a function returning xml:

create function getsubnode(@p int) returns xml begin homecoming ( select @p '@subnodeid', 'subnoddata' somedata xml path('subnode'), type ) end

use this:

select nodeid '@nodeid', nodedata data, dbo.getsubnode(nodeid), moredata node xml path('node')

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
