Hello,
I have two tables like these:
TABLE_1: people registry
fields: ID_T1, SURNAME, NAME
ID_T1 is primary key
TABLE_2: work groups
fields: ID_T2, TASK
ID_T2 is foreign key related to ID_T1
the first table is the list of employees, the second the task.
Sometime I need to insert a new employee and at the same time the task
for him:
I want to INSERT TO table 1 JOHN DOE (the ID is assigned automatically
since it's a primary key) and INSERT TO table 2 the ID and the task
name for JOHN DOE. Is it possible to create a single query? What is the
best way to do this?
Thanks,
Filippo

You need to manage the transaction: begin a
transaction, execute your first insert, retrieve the
ID with curr_val(), execute the sencond insert and
commit the transaction.

maybe you could create a view for the join of the two tebles,
then make that view writable by creating the
appropriate triggers.
Then a single insert into the view would in fact create everything.
