Thomas Fox commented on TORQUE-305:
-----------------------------------
An aspect which is not traightforward to solve is the automatic generation of
primary keys for the inserted values.
In databases which use autoincrement like mysql, this is not a problem as one
can leave out the primary key column and then get an id automatically.
For databases which use sequences, a sql expression must be inserted to get the
correct pk value. This case should be handled automatically.
Anybody using the idbroker must specify the id values manually, as theere is no
way to query the idbroker from the database.

> It would be nice if the torque criteria api would support inserts with a
> given sub query like the following:
> INSERT INTO table_a (column_a, column_b, column_c)
> SELECT
> /* Literal number values with column aliases */
> value_a AS column_a,
> value_b AS column_b,
> column_x
> FROM table_b
> WHERE ...;
