[Zope-DB] Multi table update from one input form

[Norman Khine]

I know, too long winded -- anyhow I found from the psql list that, as you
suggested previously to use a subselect sql statement, so here what the
final statement looks:
id: sql_INSERT_business_address
arguments: street_name town county postcode county_id

INSERT INTO business_address (street_name, town, county, postcode,
county_id, business_name_id) values (<dtml-sqlvar street_name
type="string">, <dtml-sqlvar town type="string">, <dtml-sqlvar county
type="string">, <dtml-sqlvar postcode
type="string">, <dtml-sqlvar county_id type="int">,
business_name_business_name_seq.last_value);

thanks for all your help

Norm
