SONAR数据库很少泄密，直接去研究了一下。经过一天反复实践，把重点的几个表来说明一下。
说明一下，SONAR提供删除项目的功能，但大量数据并没有删除掉。
select * from projects where scope='PRJ' AND qualifier='TRK' order by name;
delete from resource_index where root_project_id in (37641,37902,38053,37456,38204,38355,38506);
delete from sonar.snapshot_sources where snapshot_id
in
(
select id from sonar.snapshots where root_project_id in (37641,37902,38053,37456,38204,38355)
