Abstract
A method, computer program product, and system delete a row from a child table. The method, computer program product, and system delete the requested child row from the child table if the query corresponds to each of the plurality of parent tables and each of the plurality of parent tables has a row with a linked parent column that has a same value as a linked child column in the requested child row from the child table. Alternatively, deletion is performed if the query corresponds to only one of the plurality of parent tables having a row with a linked parent column that has a same value as a linked child column in the requested row from the child table and, for each remaining parent table, no row has a linked column that has a same value as a linked column in the requested row from the child table.
