The SchemaUpdate tool will update an existing schema with "incremental" changes. The SchemaUpdate depends upon the JDBC metadata API and, as such, will not work with all JDBC drivers. java -cp hibernate_classpaths org.hibernate.tool.hbm2ddl.SchemaUpdate options mapping_files
In the below table we can understand about the SchemaUpdate Command Line Options:
|
Option
|
Description
|
|
--quiet
|
do not output the script to stdout
|
|
--text
|
do not export the script to the database
|
|
--naming=eg.MyNamingStrategy
|
select a NamingStrategy
|
|
--properties=hibernate.properties
|

|
|
--config=hibernate.cfg.xml

Here we can embed SchemaUpdate in application below code:
Configuration cfg = ....;
new SchemaUpdate(cfg).execute(false);
