Обсуждение: Boolean type

I use the Java EJB2.0 standards for creating entitiy beans which are
persisted to a PostGreSQL database.  I create an entity
bean with a boolean attribute with value 'true'.  In the database the record
is inserted and the field value is set to 1. When I retrieve the entity bean
attributes with a findByPrimaryKey() finder method, the getAttribute()
result is 'false' for the inserted 'true' value.  Is this a type
mapping/conversion setting that needs to be set for the application server
(JBoss 3.0-alpha) or does it have to do with the JDBC driver I am using
( I use the driver that came with the Cygwin package, ie postgresql.jar)?

Thanks and regards.

No, this would be a bug. Can you try the latest jar from
jdbc.postgresql.org. If the problem persists, then we can address  it.

TIP 4: Don't 'kill -9' the postmaster

Hi to all,

This is my first msg in this list and I hope it isn't OT...

I've a java server application that accecc a database using a JDBC
driver.
Due to compare the postgres performances I made two tests with the same
java server using MS Sql 2000 and Postgres 7.2 as database.
The test reports a time 3 or 4 time longer when using postgres.
How can I investigate if the bottleneck is the driver or the database?

My first idea is a measure of query execution time with psql and via JDBC;
how can I do that?

TIA, Auri
