Hello.
I'm use Hibernate 3.2GA

In my Mapping documents:
...
<property name="goodsNumeric" lazy="false" insert="true" update="true" not-null="false" unique="false" type="java.math.BigInteger">
<column not-null="false" unique="false" name="`goodsnumeric`" precision="5"/>
</property>
...

Name and version of the database you are using:MySQL 5.0.37

From MySQL documentation
In standard SQL, the syntax DECIMAL(M) is equivalent to DECIMAL(M,0).

But In log and in database scale=2, it's have to be exactly 0.

Debug level Hibernate log excerpt:
12484 [main] DEBUG org.hibernate.tool.hbm2ddl.SchemaUpdate - create table `goodsitembasetype` (e_id bigint not null auto_increment, e_version integer not null, `goodsnumeric` numeric(5,2), `grossweightquantity` numeric(19,6), `netweightquantity` numeric(19,6), `invoicedcost` numeric(16,2), `customscost` numeric(16,2), `statisticalcost` numeric(16,2), primary key (e_id))

What I should do?
