DELETE FROM "TMPTAB"

WHERE

"Product (key)" IN

(SELECT A."Product (key)" FROM "TMPTAB" A inner join "DBTAB" B

ON B."Release Date" IS NOT NULL AND TO_DATE(A."Date (key)",'DDMMYYYY') < TO_DATE(B."Release Date",'DDMMYYYY') AND A."Product (key)" = B."Product (key)")

AND

"Date (key)" IN

(SELECT A."Date (key)" FROM "TMPTAB" A inner join "DBTAB" B

ON B."Release Date" IS NOT NULL AND TO_DATE(A."Date (key)",'DDMMYYYY') < TO_DATE(B."Release Date",'DDMMYYYY') AND A."Product (key)" = B."Product (key)");

ABC = SELECT A."Product (key)", A."Date (key)" FROM "TMPTAB" A inner join "DBTAB" B

ON B."Release Date" IS NOT NULL AND TO_DATE(A."Date (key)",'DDMMYYYY') < TO_DATE(B."Release Date",'DDMMYYYY') AND A."Product (key)" = B."Product (key)";

DELETE FROM "TMPTAB"

WHERE

"Product (key)" IN

(SELECT "Product (key)" FROM :ABC)

AND
