Deleting a report from the data mart

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.
