[postgis-users] create xml file from sql table

[zhang zhe]

hello,
I tried your code

 
psql -At -U postgres -c “select table_to_xml(‘building3’,true,true,’’);” postgres > query.xml
 
but it gives erro
ident authentication failed for user "postgres"
 
what should be the user name. I tried with localhost, it gives the same error. 
 
Do you have any idea?
 
Thanks

Hi,
 
You can use psql to run your query from the command line.
 
psql -At -U {username} -c “select table_to_xml(‘building3’,true,true,’’);” {database} > query.xml
 
-A unaligned output (no formatting of results for display purposes)
-t Rows only (ie no header, so your xml file to only has xml in it)
 
If you don’t really need an automated way you can use the “Execute query to file” option in pgAdmin.
 
Regards,
 

Josh
