A quote from persistence.xml
:
<persistence-unit name="test" transaction-type="RESOURCE_LOCAL">
<properties>
<property name="hibernate.archive.autodetection" value="class" />
<property name="hibernate.show_sql" value="true" />
<property name="hibernate.format_sql" value="true" />
<property name="hibernate.hbm2ddl.auto" value="create" />
...
</properties>
</persistence-unit>
This is what I see in log output:
Sep 30, 2010 12:03:43 PM org.hibernate.tool.hbm2ddl.SchemaExport execute
INFO: Running hbm2ddl schema export
Sep 30, 2010 12:03:43 PM org.hibernate.tool.hbm2ddl.SchemaExport execute
INFO: exporting generated schema to database
Sep 30, 2010 12:03:43 PM org.hibernate.tool.hbm2ddl.SchemaExport execute
INFO: schema export complete
But I don't see the schema (SQL) exported itself. How to get this information out of Hibernate (3.5.6-Final)?
Activate the logging of the org.hibernate.tool.hbm2ddl
category to DEBUG
.
Update: Here is a simplified logback.xml
(I'm using logback as logging backend):
<configuration scan="true">
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<layout class="ch.qos.logback.classic.PatternLayout">
<Pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</Pattern>
</layout>
</appender>
<!-- ### log just the SQL ### -->
<logger name="org.hibernate.SQL" level="DEBUG"/>
<!-- ### log JDBC bind parameters ### -->
<logger name="org.hibernate.type" level="TRACE"/>
<logger name="org.hibernate.tool.hbm2ddl" level="DEBUG"/>
<root level="ERROR">
<appender-ref ref="STDOUT"/>
</root>
</configuration>
Adapt it if you are using log4j (you'll find working configuration here on SO).
