Yes - that's right. It saves you from having to keep track of things like
PKs in your application, although in fact any column can be an auto
increment column.

>When I insert a new row, how do I know which row I just inserted?  IOW, how

InstantDB has a proprietary extension:

Object idbConnection.getLastValueInserted(String tableName, String
columnName)

that does this. See

http://instantdb.enhydra.org/software/documentation/jdbc.html

for details.

>Also, Is this a SQL92 standard?

No. AFAIK, there is no standard way of supplying auto values or determining
the last inserted.
