Procedure

  1. In the Data Explorer perspective, open an editor.
  2. Enter the following SQL query in the editor and execute it in the order shown below:
    use talend_dq61;
    /*must execute the sql in this order*/
    /*1. delete data from tdq_indicator_value table*/
    delete from tdq_indicator_value where analysis_pk in (select an_pk from tdq_analysis where rep_uuid in ('_EuRp8Ey8EeWI7MB95QH5HA', '_cabpUUzUEeW6FuESwuuXqA'));
    /*2. delete data from tdq_overview_indvalue table*/
    delete from tdq_overview_indvalue where an_pk in (select an_pk from tdq_analysis where rep_uuid in ('_EuRp8Ey8EeWI7MB95QH5HA', '_cabpUUzUEeW6FuESwuuXqA'));
    /*3. delete from tdq_set_indvalue table*/
    delete from tdq_set_indvalue where an_pk in (select an_pk from tdq_analysis where rep_uuid in ('_EuRp8Ey8EeWI7MB95QH5HA', '_cabpUUzUEeW6FuESwuuXqA'));
    /*4. delete from tdq_analyzed_set table*/
    delete from tdq_analyzed_set where match_ind_pk in(select m_pk from tdq_match_indvalue where analysis_pk in (select an_pk from tdq_analysis where rep_uuid in ('_EuRp8Ey8EeWI7MB95QH5HA', '_cabpUUzUEeW6FuESwuuXqA')));
    /*5. delete from tdq_match_indvalue table*/
    delete from tdq_match_indvalue where analysis_pk in (select an_pk from tdq_analysis where rep_uuid in ('_EuRp8Ey8EeWI7MB95QH5HA', '_cabpUUzUEeW6FuESwuuXqA'));
    /*6. delete from tdq_table_analyzed_set table*/
    delete from tdq_table_analyzed_set where an_pk in (select an_pk from tdq_analysis where rep_uuid in ('_EuRp8Ey8EeWI7MB95QH5HA', '_cabpUUzUEeW6FuESwuuXqA'));
    /*7. delete from tdq_analysis table*/
    delete from tdq_analysis where rep_uuid in ('_EuRp8Ey8EeWI7MB95QH5HA', '_cabpUUzUEeW6FuESwuuXqA');

    In this example, you want to delete the two reports which have the identifiers _EuRp8Ey8EeWI7MB95QH5HA and _cabpUUzUEeW6FuESwuuXqA from the talend_dq61 data mart.

  3. Execute the SQL query to delete the reports.
  4. To make sure the reports have been deleted, in an SQL editor, re-run the following SQL query:
    use talend_talend_dq61;
    /* get report UUID */ 
    select  REP_UUID, REP_LABEL  from tdq_analysis where REP_LABEL like 'c%'

Results

The two reports which have the identifiers _EuRp8Ey8EeWI7MB95QH5HA and _cabpUUzUEeW6FuESwuuXqA have been deleted from the data mart.

The reports have been deleted from the TDQ_ANALYSIS table. All facts (analysis results) related to these reports have been deleted from the fact tables.
