.. that you experts I hope can crack like a digestive biscuit... how does one update, or merge or whatever is right technical term for it - a my.table from my.another table (both are schematically identical, no foreign keys, one primary key) but.. does it a way so when there is a duplicate only NULLs in my.table get updated/replaced with proper values from my.another table? many thanks, specially for actual syntax hints.
