update ureport2_data
set r_data = replace(r_data, '<datasource name="master" type="jdbc" username="username" password="password" url="url" driver="org.postgresql.Driver">', '<datasource name="System" type="buildin">')
where r_data like '%<datasource name="master" type="jdbc" username="username" password="password" url="url" driver="org.postgresql.Driver">%'
