is it possible to update an existing row in DB, using liquibase?
You can use the following liquibase syntax to update:
<changeSet author="myname" id="7799"> <update catalogName="dbname" schemaName="public" tableName="TABLENAME"> <column name="COL1" value='1' type="varchar(50)"/> <where>col1='123'</where> </update></changeSet>For the other options available please check Liquibase Update
