Hi all,
We have an application based on DB2 database, We are testing this same
application on PostgreSQL database. By default we are in autocommit on
mode.
On DB2 (and Oracle), the query SELECT FOR UPDATE locks the row until the
resultset is closed. On PostgreSQL database (all versions) this same query
never locks (because we are in autocommit on mode). But this is a bad
implementation of JDBC specification : "If a connection is in auto-commit
mode, then all its SQL statements will be executed and committed as
individual transactions.[...] The commit occurs when the statement
completes or the next execute occurs, whichever comes first. In the case
of statements returning a ResultSet object, the statement completes when
the last row of the ResultSet object has been retrieved or the ResultSet
object has been closed."
Is it possible to lock row in autocommit on mode on PostgreSQL database ?
