need some help with an opennms query/insert

Hey guys,

I am an OpenNMS admin and new to Postgres. I have just updated around 1100 devices manually with multiple categories and left out a category from each... What I would like to do is run a sql statement that will select any node with a category ID of X and add to that node a category ID of Y....

pgsql 8.1.5

table looks like this:

public.category_node (trimmed to one nodeid)

categoryid nodeid
27 865
26 865
I want to search all rows for categoryid of 27, then insert a row with categoryid of 30 to that same nodeid. so it would look like this.

categoryid nodeid
27 865
26 865
30 865

I think I have this much:

SELECT "categoryid" FROM "public"."category_node" WHERE "categoryid" = '27'

Is this the right track? and then, how do I insert a row?

thanks!

-P
