</liquibase:updateDatabase>

A basic implementation of the update database task. Applies updates in the changelog file to the database.

<database  id="my-database"  driver="${driver.classname}"  url="${jdbc.url}"  user="${username}"  password="${password}"/>  
<liquibase:updateDatabase  databaseRef="my-database"  changelog-file="/path/to/changeLog.xml"/>

Updates the referenced database with the changeset found in the given changelog file.

<liquibase:updateDatabase  changelog-file="/path/to/changeLog.xml">  
	<liquibase:database  driver="${db.driver}"  url="${db.url}"  user="${db.user}"  password="${db.pasword}"/>  
	<liquibase:changeLogParameters>  
		<liquibase:changeLogParameter  name="property1"  value="value1"/>  
		<liquibase:changeLogParameter  name="property2"  value="value2"/>
