I am using 7.2 and JDBC. I have a very simple situation where I
insert an item with a primary key which is a SERIAL. In the same
transaction I need to insert a reference in a separate table to this
item. Of course, race conditions could occur if I didn't use this
special isolation level. But is there no way in which I could use
row-level locking instead? Certainly, I am not updating the table I
just inserted to, so the FOR UPDATE would never unlock. Is the
isolation level my only option? I noticed that psql displays the oid
after an INSERT. That would be exactly what I need but JDBC doesn't
seem to offer this.
(Right now I set the isolation level and just get the SERIAL's current value.)
|---table1----------------| |---table2-----------------|
| id SERIAL PRIMARY KEY | | id SERIAL REFERNCES table1 |
Short version:
I just inserted into table1 and need these in the same transaction.
How can I get the id I just inserted into table2? Thanks folks.
