Hello, I am trying to use the INSERT ON CONFLICT syntax to build an SCD 2 table loader.
here are the behaviors I need to achieve: SCD 2 table: TAB_OUT new candidate records: TAB_IN The table TAB_IN contains the new candidate records to be submitted to TAB_OUT. *Case 1*: The record presented by TAB_IN is already present in TAB_OUT and the fields were not modified -> DO NOTHING *Case 2*: The record presented by TAB_IN is not present in TAB_OUT -> INSERT NEW RECORD (*OK*) *Case 3*: The record presented by TAB_IN is already presente in TAB_OUT and the fields were modified -> CLOSE existing record in TAB_OUT(*OK*) -> *INSERT new RECORD (KO)* I can't find a way to retrieve the list of records that were updated ON CONFLICT. I have tried the RETURNING but, it is retrieving the list of records processed either in the INSERT or the UPDATE. Am I missing something or it is not possible with this syntax? Thanks in advance Johann
