Patch fixing HHH-2962 - "ResultCheckStyle.PARAM does not work with PostgreSQL"
------------------------------------------------------------------------------
Key: HHH-2986
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2986
Project: Hibernate3
Issue Type: Patch
Affects Versions: 3.2.5, 3.2.6, 3.3, 3.4
Environment: Hibernate 3.2.5, PostgreSQL 8.2 & 8.3beta
Reporter: Julius Stroffek
Attachments: hibernate.diff
I have created a simple test application which uses a stored procedure
to insert a record into a database using hibernate. I used hibernate
annotations and have overridden insert statement by
@SQLInsert(callable=true, sql="{? = call insert_party(?, ?, ?, ?)}",
check=ResultCheckStyle.PARAM)
However, hibernate throws the exception
...

The patch fixes this issue by calling
CallableStatement.getBigDecimal(parameterPosition).intValue() instead of
CallableStatement.getInt(paramterPosition).
I studied JDBC3 specification whether PostgreSQL driver is wrong
or not and I think that the driver is correct. There is a conversion table
on page B-182 which should correspond to ResultSet object getter
methods only. There is nothing about the conversion being done
in CallableStatement's getter methods.
Hibernate should use CallableStatement.getBigDecimal(parameterIndex).intValue()
to obtain a value of a output parameter of NUMERIC data type.
