Hi Tom,
Thanks for this, would the sql be something like
INSERT INTO business_address (business_name_id) select
currval('business_name_business_name_seq');
Is this correct? If so, how do you Insert the other values that are not
associated with the sequence i.e address, town etc....
can i do something like
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">, select
currval('business_name_business_name_seq');
This does not work?!As I get a parse error near "select"
What should be the correct syntax for embedding this.
Thanks
Norm
