Thread: postgresql 7.4.6-6, hibernate-2.1.6, jdbc3
Hi, I have postgresql 7.4.6-6, hibernate-2.1.6, jdbc3 (pg74.215.jdbc3.jar). I get this exception: I have a pretty complex structure, but here I try to do a simple thing: SomeBean foo = (SomeBean) session.get(SomeBean.class, primary_key_value); I have: <property name="show_sql">true</property>, so I tried executing the query it generated directly, it executed without problems. -- Pavel Jbanov http://www.spicesoft.com/~pavel/
Sorry, gone unfinished. :/
The exception is:

What should I look at? Where can be the cause?
Thanks.

Byte f > at > org.postgresql.jdbc1.AbstractJdbc1ResultSet.getByte(AbstractJdbc1ResultSet.java:244) I'd need to see the untranslated exception message to be sure, but.. getByte() expects a numeric value (TINYINT, although SMALLINT/int2 is the closest mapping in PostgreSQL). You appear to be trying to retrieve a text/varchar (or possibly boolean) value that can't be parsed as a numeric value. (there might be a driver bug here -- the JDBC datatype conversion tables indicate you can use getByte() on BIT/BOOLEAN, but I'm not sure what the exact conversion should be) -O
In addition: the query is: select contact0_.contact_id as contact_id0_, contact0_.account_id as account_id0_, contact0_.created as created0_, contact0_.first_name as first_name0_, contact0_.last_name as last_name0_, contact0_.middle_name as middle_n6_0_, contact0_.home_phone as home_phone0_, contact0_.cell_phone as cell_phone0_, contact0_.business_phone as business9_0_, contact0_.additional_phone as additio10_0_, contact0_.fax as fax0_, contact0_.email as email0_, contact0_.email2 as email20_, contact0_.res_address as res_add14_0_, contact0_.res_city as res_city0_, contact0_.res_country as res_cou16_0_, contact0_.res_postal as res_postal0_, contact0_.res_province as res_pro18_0_, contact0_.mail_address as mail_ad19_0_, contact0_.mail_city as mail_city0_, contact0_.mail_country as mail_co21_0_, contact0_.mail_postal as mail_po22_0_, contact0_.mail_province as mail_pr23_0_, contact0_.mail_same as mail_same0_, contact0_.modified as modified0_ from contact contact0_ where contact0_.contact_id=?

Right, I had bool there. I've changed it to bit, now it works. Thanks.

Isn't 0/-1 more common in the SQL world? -O
