# how to get the variable per row, which will be the link target?
#
# first, we extend the multirow so that it contains an additional
# column (other than the columns in the select list from the query).
#
# The name of that column is view_url, and we're using export_vars
# to actually form the value. This invocation of db_multirow has an
# extra parameter at the end, which is a block of code to execute.
# In this block, we set the extra column variable we told it about
# with the -extend {} parameter.
#
# This variable will then be available to anything that reads the
# multirow, which for this case is the template::list::create call
# above.

db_multirow -extend { view_url } template_demo_notes template_demo_notes {} {
    set view_url [export_vars -base view-one { template_demo_note_id }]
