Getting Issue when Liquibase trying to execute Oracle query

Hi Team,

Our application having following technologies,
Grails 1.3.7, Oracle XE, Database-migration-1.0 plugin and Liquibase 2.0.1.
In this application we are using Database-migration-1.0 plugin which uses Liquibase 2.0.1 library to manage DB changes.

Here DB changes are done in separate changelog files(eg., r18-base.groovy, r18-to-r19-baseline.groovy, R19-add-contractToSite.groovy) and these files are incorporated into a root file(changelog.groovy).

When we are updating the DB using Could you please clarify this issue?
